Chapter 1

Parking Heater Definition –What is a Parking Heater?

A parking heater is an electro-mechanical device that uses air or liquid (water) to warm/heat the interior and engine of a motor vehicle to a suitable temperature.

By burning various fuels such as diesel or petrol in its combustion chamber, it transfers this heat to flowing air or liquid (water) through its heat exchanger system. The heated liquid or air, then flows to other parts of the vehicle.

These heaters feature modern technologies with various sensors and microprocessors to ensure seamless operation. The technology ensures safety, low fuel consumption and the overall efficiency of this system.

Of course, this is possible with the various parts of parking heaters that perform different functions. Besides, it will also depend on the design and the model of the heater.

Parking Heater

You will learn more about this shortly, keep reading.

VVKB Parking Heater

This is a VVKB Parking Heater

Basically, with an electric or diesel parking heater, you can conveniently heat various parts of the vehicle even before starting the engine. It is an auxiliary heating system for vehicles such as cars, commercial vehicles, buses, etc.

More importantly, you can control how a parking heater works using a smartphone, remote control or a timer. So, you don’t have to leave the house or be in the vehicle to start the heating process.

Such performance is only possible when you buy a quality parking heater that conforms to all quality regulations/standards such as CE, FCC and RoHS, just to mention a few.

In short, vehicle heaters are convenient to operate, improve comfort and guarantee significant cost saving.

In case you are new to the parking heating technology, then this is a must-read eBook.

Now, let’s see how this vehicle heater works.

Chapter 2

Parking Heater Function: How does a Parking Heater Works?

In this section, you are going to learn how a parking heater works. It will focus on the basic working principles, without going into an in-depth analysis of each component.

You’re going to learn more about every component/parts of the parking heater later in chapter 6.

For now, I want you to have a quick overview of the diagram below. I will use it to explain the working principle of a parking heater.

VVKB Parking Heater Features

A section of VVKB Parking heater – Image source: SOLIDROP

Now, let’s jump right into the main subject of this section:

As a quick reminder, parking heaters are available for nearly any vehicle, be it cars, trucks, buses, etc. They use a simple principle of operation to warm both the passenger compartment and engine of the vehicle.

Such parking heaters basically have what we call a dual function capability.

With these parking heaters, you can warm your vehicle without the engine running. They are basically auxiliary heating systems.

Their structures, positions and designs are completely different from the normal heating systems in the cabin of a car.

Here is a step-by-step process how the heating process takes place:

Step 1: Start the Parking Heater

First, you should install the parking heater as per the manufacturer’s instructions. It is a simple process as you will see later in chapter 7 of this complete guidebook on how a parking heater warms up cars.

Second, you can go ahead to switch on the gasoline or diesel parking heater using any of these:

  • Mobile phone
  • Preset timer
  • Remote control

This will depend on the design and configuration of the parking heater system.

Once you turn on the parking heater, its control system or computer circuit board will run system diagnostic tests to ensure every component is in a proper working condition.

You can see this in the image above part no. 3. This system controls and executes various commands depending on the signal it receives.

In short, it is through this system that the parking heater manufacturer can easily automate the working process alongside various safety measures.

Once the parking heater system is in good condition, the motor fan will begin to rotate. As a result, it will supply high speed air into the system.

At this stage, you can choose appropriate settings of the machine and you will begin to see various parameters on the heater’s display. For example, the parking heater will display the ambient temperature of the system.

Furthermore, you can set the system to a heating mode.

Step 2: Air and Fuel Flows into the Parking Heater

To generate heat, combustion must take place.

Well, the idea here is not very different from the internal engine combustion of motor vehicles.

So, here is what happens next:

After step 3, the motor speed slows down as the ignition plug kicks in. By doing so, it preheats the combustion tube.

parking heater system air and fuel flow

Parking heater system showing flow of air and fuel

I hope you can see the combustion chamber (part no. 6).

The fuel pump/dosing pump begins to deliver fuel to the parking heater system. The fuel can be from the vehicles’ tank or a separate system.

At the same time, the glow plug (part no. 5) receives electric current which it uses to ignite the fuel after atomization. Meanwhile, the combustion air fan (part no. 4) keeps pushing air into the combustion chamber.

As the ignition plug ignites the mixture of fuel and air, the temperature/heat and flame monitoring sensors will detect and monitor every step in the combustion chamber.

Remember, combustion can only take place after the system reaches a suitable temperature (depending on the design). Besides, there should be a sufficient amount of fuel and air.

At this stage, the heater system will control flow of air, fuel and of course the combustion in the system.

So, both air and fuel will continue to burn and the exhaust leaves the system. You can see the position of the exhaust system in image 2 above.

Up to this, there is combustion going on within the parking heater system. This implies that, there will be heat within this system.

Now, how does this heat reach other components or parts of the car?

Let’s see what happens next:

Step 3: Warming Passenger Compartment & Engine

Since we have a sufficient amount of heat in the parking heater, it is now time to distribute it to other sections of the car.

So here, the parking heater may use either water or air. Like in the examples above, the two parking heaters use air.

As you can see from the diagram, cold air enters while hot air leaves the parking heater system. That is the same scenario you will find in those that use water (cold water enters and leaves when hot/warm).

This is exactly what happens:

Once there is sufficient amount of heat in the parking heater, it will warm (transfer heat) the flowing air/water via its heat exchanger. You can see the location of heat exchanger in image 2 above.

Air or water will then flow to the car’s heat exchanger system from where it will direct warmth to the interior section (passenger compartment). That is, it uses the car’s ventilation system.

Depending on the design of the fuel operated heaters, the warm water/air will then flow to the engine. It warms the engine making it easy to start your vehicle even during cold weather.

From the engine, used water/air flows back to the parking heater and this cycle continues. Remember, this water/air is generally cold or has dissipated significant amount of heat as it flow through the car’s heat exchanger and the engine.

Step 4: Switching Off Parking Heater

Once both the car’s interior and engine have attained a desirable temperature/heat, you can go ahead to switch off the fuel operated heaters.

When the system receives a signal to stop the heater, its fuel pump will stop working. This will cut off the fuel supply.

At the same time, the ignition plug will run for a while to burn all the remaining fuel. On the other hand, the high-speed motor will also blow all burned carbon or residue from the heater while cooling it at the same time.

The fan’s speed will later reduce until it stops. It will also switch off the current supply of the system.

As you can see, the working principle of parking heaters is simple and straight forward.

Remember, the sequence of events in this system may vary depending on their unique designs. Therefore, it is important that you refer to the technical manual to know more about the parking heater model/brand.

With all these in mind, now let’s move to yet another critical aspect of fuel operated heaters.

Chapter 3

Parking Heater Benefits: Why Do You Need a Parking Heater?

parking heater benefits

Unlike other car accessories, we do not just install parking heaters for the sake of it. This equipment plays a pivotal role in extremely cold weather, more so when the temperatures drop to freezing point.

I know many of you have come across many forums on how cold weather affects fuel efficiency and overall driving experience. In most cases, you will find one of the most common advices being parking the car in warm places with an aim of increasing initial engine temperature.

But, the question is: What if you cannot afford such a place?

Well, this is the point where you need a gasoline, diesel or an electric parking heater depending on the design of your car.

So, below are some of the key parking heater benefits:

1. Guarantees Safety by Ensuring Clear Visibility

At times, not even the scraper will remove all ice from your windscreens. Even if it removes, there is a chance of leaving misting or humid surface.

To make it worse, there is always a possibility of ice forming again.

car interior and windscreen

The interior of the car and windscreen remain clear without wither ice or mist

This makes a car heater a perfect alternative for this job since it will cause all ice to melt, leaving a clear surface without any obstructions. By defrosting all windows, you will obviously have a clear view hence more safety.

2. Ensure Significant Cost Savings in the Long run

In most cases, a diesel parking heater may cost between £399 and £430, depending on the size, design, power rating, etc. On the other hand, the idling fuel cost in a year is more than £2,206.

Parking heaters use a small amount of fuel to preheat the passenger compartment and the car’s engine. Therefore, this will reduce the idling time and cost.

At the same time, with these parking heaters, your car will bypass cold starting the engine. Cold starting burdens the engine, hence resulting in high and fast wear.

As a result, you may end up repairing your engine frequently, which will result in high costs. So, bypassing cold starting will result in significant cost saving.

3. Parking Heaters Improve Comfort

Gone are the days when you could freeze in the car when the snow covers the entire surface or, the external environment is extremely cold.

The parking heater will maintain a comfortable temperature. Thus, you will not shiver or experience frozen hands while driving.

Uncomfortable car interior due to cold

As a result, it will improve your driving experience during all seasons.

4. Convenient and Easy to Operate

The modern control heaters are fully automated with better control mechanisms for low fuel consumption, safety system diagnostic and easy to operate features.

A general purpose control panel for VVBK car heaters

Depending on the design of your fuel operated car heater, you can switch it on using a wireless remote or an app installed in a mobile phone. During the heating process, you can monitor the operation conditions of the parking heater.

Of course, the fact that you do not have to scrape ice from the windscreens and windows makes it even more convenient too. In addition to this, it will save you a lot of time as well.

5. They Offer Intelligent Ventilation during Summer

Its design is such that the parking heater can cool cars during summer through the ventilation system that prevents excessive heat buildup.

Normally, it allows fresh external air to flow freely into the car when parked. This makes it a perfect accessory for both winter and summer seasons.

6. Low Environmental Pollution

The amount of exhaust gas your vehicle will produce when in idling state is much higher than that of parking heater. So far, there is a preliminary research that has established that using a parking heater to warm car engine and passenger compartment reduces pollution by over 47%.

In short, buying a high quality and reliable fuel operated heaters with versatile control systems alongside on-board diagnostic features will definitely give you a peace of mind.

Now that you know the benefits parking heater, which design or model is suitable for your car?

Keep reading to learn more about the various types of parking heaters available in the market.

Chapter 4

5 Main Types of Parking Heaters Recommended

There are many types parking heaters available in the market. Mostly, you may classify these heaters depending on their shape, size, design, heating mechanism, etc.

For the scope of this parking heater guidebook, the discussion will be restricted to the following:

  1. Air based parking heaters
  2. Coolant based parking heaters
  3. Electric parking heaters
  4. Diesel parking heaters
  5. Gasoline parking heaters

Now, let’s have a quick overview of these types of parking heaters you can consider for your car, delivery van, yacht or buses.

Air Based Parking Heaters

The parking air heating systems are by far the most popular accessories in this industry due to their cost effective design. They are low power consumption heating systems that are easy to install.

Below is an example of an air parking heater:

Air parking heater

Air parking heater

The working principle of air parking heaters is based on the following key principles:

  • Heater system draws in fuel and air, which mix and burn to produce heat.
  • Meanwhile, the blower of parking heater system sucks cold air. This can either be from the outside environment or vehicle system, depending on the design.
  • It then forces this air to flow through the parking heater’s heat exchanger. During this stage, this air becomes heated.
  • The parking heater, then forces the air into the vehicle system, thereby elevating temperature to the required threshold.

Due to its design, the air parking heaters release the heat faster since all heated air is blown into the vehicle system directly.

In most cases, you can install an air parking heater system under your vehicle’s chassis or cabin.

Moreover, you can use a timer, remote/wireless system or mobile phone to activate the heating system.

These are air based parking heaters are easy to operate and they come in many shapes or sizes. This will depend on the heating capacity that your lorry, truck or car requires.

A good example of air based parking heater is the VVKB 12V 5KW Parking Heater Apollo-V2.

Coolant Based Parking Heaters

The good thing about the coolant based parking heaters is that, they heat both the passenger/driver’s cabin alongside the car engine. Therefore, you not only realize a comfortable environment within the car, but also avoid instances of cold starting the engine.

coolant based parking heaters

One of the most popular accessories in this category is the water parking heaters. At times, you may refer to them as liquid parking heaters.

Water parking heater

Water parking heater

In most instances, you should install the water parking heaters within the engine compartment. This is because it will use the water circuit system of the vehicle.

The design and structure of this accessory resembles that of the air parking heaters except that, we replace air with the water.

That is, once there is combustion is the heating chamber, cold water from the vehicle system will flow through the parking heater’s heat exchanger system.

The hot/warm water will then flow to the car’s heat exchanger (part of the vehicle’s ventilation system) where it dissipates some heat. A fan will then blow this heat into the vehicle’s system, thereby heating the passenger and driver compartment.

At the same time, this water will again flow through the engine. It heats up the engine, thus bypassing instances of cold starting.

Like the air parking heaters, you can also start these systems using a digital panel, wireless/remote device or mobile phone.

In addition to these dual functionalities of water parking heaters, you can use them to aerate the car during summer.

When you observe these two parking heaters, it is quite clear that the main difference is how the system extracts heat from the heat exchanger of the device to other parts of the car.

It forms the first and a critical classification criterion of various types of parking heaters.

Next, the main focus will be on how these systems generate this heat. Let’s begin with:

Electric Parking Heater

This is an environmentally friendly parking heater since it does not produce any emission like in the case of fuel operated designs.

With a conventional 230V power source, you can heat both the car engine and passenger compartment. This makes it a cheaper way to heat the car during cold weather.

Furthermore, the design of these heaters is such that whenever the heater is on, the car battery begins to charge automatically. A good example of an electric parking heater Webasto’s eThermo Top Eco whose working principle is almost the same as the VVKB Electric Heater.

electric heater parts

Components and parts of an electric heater

Once you connect it to a source of power, the coolant will circulate through the electric parking heater, vehicle’s heat exchanger system and to the engine. This cycle continues until both the engine and passenger compartment attains sufficient heat.

The electric parking heater heats the coolant then it dissipates this energy to the surrounding air in the vehicle’s heat exchanger. The vehicle’s fan blows the hot/warm air to the vehicle’s interior.

This coolant then flows back to the engine to heat it up. You can see how this works in the image above (follow the direction of the arrows).

Apart from heaters that use electric energy, there are those that use either gasoline or diesel.

Diesel Parking Heater

These parking heaters use diesel as their main source of fuel, hence, their name. They are suitable for diesel vehicles since it is easy to integrate them with the existing fuel system.

A good example of such accessories is the VVKB Apollo-V1 New Diesel Air Parking Heater.

diesel parking heater

Diesel parking heater

Depending on the design of the diesel parking heater system, you can use either air or water to transfer the heat it generates to other parts of the vehicle.

Gasoline Parking Heater

Just like the name suggests, these parking heaters use gasoline as the main source of fuel. They burn gasoline to produce heat that elevates the temperature of either air or water.

Moreover, gasoline parking heaters are common in vehicles that use gasoline as their main source of fuel.

So, generally, there is no big difference between the gasoline parking heater and diesel parking heater except for their main source of fuel.

You can read this article to learn more about: gasoline vs. diesel engines.

Apart from these five critical ways of classifying various types of parking heaters, the design and functionality are also critical aspects to consider.

For instance, you may have a removable all-in-one unit, which by far is one of the most popular in many cars.

As a rule of thumb, it is important to choose a parking heater that fits perfectly in your car without necessarily making several adjustments to the existing system. This will reduce installation costs significantly.

That being said, let’s now review some of the critical aspects that determine the price of a parking heater.

Chapter 5

Parking Heater Price: What is The Parking Heater Cost?

The parking heater price varies depending on a wide range of factors, some of which I will discuss in this section. This is why it is nearly impossible to give a fixed value.

First, let’s have a quick overview of various parking heater costs (these are few samples):

Type of Parking HeaterBrandPrice ($)
12V 15Kw Diesel Air Parking HeaterVVKB429.90
24V 5Kw Diesel Air Parking HeaterVVKB679.00
12V 2.5Kw Diesel Air Parking HeaterVVKB673
12V 2KW Gasoline Air Parking HeaterWebasto432.17 to 447.92
2.2Kw Diesel Air Parking HeaterWebasto452.27 to 468.75

As you can see, there is variation in parking heater cost.

So, what exactly contributes to the unit price of parking heater?

5.1. Brand & Model of the Parking Heater

We are in a free market where every manufacturer is at liberty to have their unique pricing model. It is for this reason that you will find that the VVKB parking heaters are more cost competitive than Eberspacher or Webasto parking heaters, yet their performance and functionality is the same.

In most cases, you will find big brands having high price tags for their parking heaters.

But even as you evaluate the parking heaters depending on their brand or model, here is one key aspect to consider – quality.

5.2. Quality Determines the Parking Heater Cost

Why should parking heaters with the same specifications and performance (i.e. based on the manufacturers’ description) have a price difference of more than USD 210? Assuming the target market is the same with parking heater manufacturers located in one geographical location.

It is even interesting to find all the manufacturers claiming that their parking heaters meet the international standards such as FCC, CE, RoHS, etc.

Well, there is something more than what meets the eye. That is exactly what I want to discuss here.

It is important that you note the following:

5.2.1 Material for Parking Heaters

Quite a number of manufacturers opt for Nylon 66 for parking heater casing. This material is strong and resistant to high temperature.

Such parking heaters are durable with consistent performance.

You cannot compare them to those made from recycled Nylon materials, which are mostly cheap. By the way, the casing of such heaters can produce pungent smell.

In addition to these, the parking heater manufacturer can also opt for an A380 aluminum casing. Of course, this is the best grade and not the recycled aluminum casings that can either melt or corrode.

5.2.2 Appearance of the Parking Heaters

Aesthetic value is very critical in any parking heater market.

Appearance of the Parking Heaters

For a fact, you cannot install a parking heater with a poor finishing or rough surface in your high end car. In fact, by looking at the surface finish, you can easily judge whether the manufacturer is serious or not.

VVKB parking heater with a fine finish

VVKB parking heater with a fine finish

Obviously, accessories with a fine, smooth and attractive finish will be more expensive. It is a clear indication of high quality workmanship.

5.2.3 Consider Type & Size of Connecting Wires Connecting Wires

Be it electric parking heater or fuel operated parking heater, quality of the connecting wires will determine the overall cost of these accessories.

parking heaters type & size of connecting wires

For example, you will find cheap parking heaters having very tenuous wires that can burn out and cause fire. On the other hand, high quality parking heater use wires with an appropriate cross-sectional area that can handle the high starting current (it can go up to 8A).

In addition to these, the wire sheath or covering should be corrosion resistant, a perfect insulator, non-ignitable, resistant to temperature fluctuations, etc. It is only Teflon that meets this criterion.

For a fact, Teflon is an expensive material, though durable and reliable.

teflon cover

Wires with Teflon as a cover

Therefore, do not expect parking heater prices to be the same for those that feature Teflon and normal polyvinyl chloride (PVC) as wire sheath/cover.

5.2.4 Number of Parts and Components of Parking Heater

parking heater components

An electric, gasoline or diesel parking heater may have many parts depending on the design, capability and technology. You will learn about parking heater parts and components shortly in chapter 6.

So here are a few things you should remember:

  • Number of parts/components will affect the parking heater cost
  • Technology; a company may opt for a low-end 8-bit chip which is obviously very slow, with some using few sensors and fragile components.
  • Design of the combustion chamber; cheap parking heaters feature either 203 or 304 stainless steel, and not the recommended 2025. Using low quality material makes combustion chamber susceptible to deformation and this may increase fuel consumption, thereby reducing the service lifespan of the system.

Furthermore, the type of fuel determines the design of a combustion chamber. This can either be gasoline or diesel.

  • Parking heater base gasket; high quality parking heaters feature base gaskets that can withstand a wide range of temperature such as -40°C to 150°C. This makes silicon-rubber a perfect choice here and not nitrile rubber, which is common in many cheap parking heaters.

Low quality base gaskets will burn out, thus producing pungent smell. Therefore, it will not keep your car cabin free from exhaust gas.

Apart from these, other factors that will determine the parking heater price include:

  • Ability of the parking heater to fit and heat all kinds of vehicles
  • Safety features and technologies such sensors, low voltage protection circuit, auto stop, alarms, etc.
  • Fuel and heating efficiency

As a rule of thumb, it is important to give quality the first priority and not price. This is the only way to get value for your money.

You should always insist on buying parking heaters that come with a warranty.

Generally, the price of parking heaters may range from USD375 to USD2, 000. You can buy them online from Amazon, eBay, Alibaba or any other B2C retail platform.

Alternatively, you can contact the parking heater manufacturer. Later in chapter 10, we will review the top 5 parking heater manufacturers in the global market.

For now, let’s look at yet another critical aspect of parking heaters – parts and components of parking heaters.

A thorough understanding of this chapter is critical in installing, operating and troubleshooting parking heaters.

So, let’s jump right in the parking heater parts and components.

Chapter 6

Parking Heater Parts: 21 Main Parking Heater Components

As you will realize in this section, a parking heater is an assembly of over 21 parts and components. However, for the scope of this section, the main focus will be on the most common parts of parking heaters.

Parts of parking heaters

Parts of parking heaters

With this information, you can comfortably assemble, disassemble or repair various types of parking heaters.

Let’s dive right in the main subject of this section:

Parking Heater Casing

This is the outer cover of parking haters. It can be aluminum 380, Nylon 66 or any other material that is heat resistant, durable, temperature resistant, etc.

Here is a good example:

VVKB parking heater parts

VVKB Parking Heater

As you can see from the example above, the parking heater casing is an assembly of many parts and components that may vary depending on its design.

Take for instance, in the example above we have:

  • Top cover as part (a)
  • Air inlet as part (e)
  • Hot air outlet as part (c)
  • Bottom cover as part (b)
  • Part (d) has fuel and combustion air inlet and exhaust outlet

All these parts are assembled using screws or any other viable locking mechanism.

Of course, for water parking heaters, you’ll have water inlet (cold) and outlet (warm/hot).

From chapter 2 (the working principle of parking heaters) the quality of this casing will determine the efficiency of the entire system.

Moreover, the design of the parking heater case should be that it is easy to install and can protect various components from shock or any other possible damage.

So, whenever you intend to maintain or disassemble parking heater, you have to open this casing using appropriate tools.

Combustion Chamber

Below is an image showing the exact location of the combustion chamber of a parking heater.

Internal section of the parking heater

Internal section of the parking heater

It is in the combustion chamber (part 6) that fuel and air mixes. With the help of an ignition plug (part 5) the mixture begins to burn producing enough heat to increase the temperature of either air or water.

Quite a number of parking heaters combustion chambers are made by die casting aluminum. Besides, they have radiating fins on the rear section of the combustion chamber thereby forming a critical section called heat exchanger system (part 7).

It is through this exchanger that heat from the combustion chamber reaches water or air, to warm other components of the vehicle.

Other parts of the combustion chamber are combustion pipes and combustor core. You can see these sections after dismantling the entire parking heater combustion chamber.

The design of combustion chamber and air to fuel mixture ratio alongside the ignition plug will determine the efficiency of the parking heater system. That is, it should produce sufficient amount of heat that can be transferred to either water or air.

The transfer of heat must be efficient with minimal losses.

parking heater

Therefore, it is important to monitor all processes and variables in the parking heater’s combustion chamber. It is for this reason that modern parking heaters feature advanced sensors and up-to-date control chips.

Control System of a Parking

Here, we refer to all components that are responsible for sensing, executing and displaying certain parameters in the parking heater system.

From the second image in this chapter (point 2), you can see the position of the controller – part marked 3. It is just behind the heating fan blade of the system.

It is this system that controls, monitors and impalements certain safety issues in this system. Throughout this time, the controller system will automatically adjust the working cycle to meet the specific heating demands of the car, truck, bus, etc.

Among the key issues that it controls include:

  • Rotation of the motor’s fan
  • Working of the fuel pump
  • Switch on/off of glow plug
  • Receiving and interpreting signals from sensors
  • Monitoring temperatures of furnace, heat exchanger and the entire system
  • Stopping the device in case of any malfunctions such as broken circuits, ignition failure, short circuit, etc.
  • Displaying parameters of the system on the control unit such as temperature alongside other status of the system

Both temperature and flame monitoring sensors are some of the critical accessories in parking heaters that guarantee safety.

Webasto GSM parking heater control system

Webasto GSM parking heater control system

In addition to these, the efficiency of the control unit will depend on the type of microprocessor/chip. It should be fast to respond to any changes in the system variables.

Therefore, you should avoid parking heaters that come with a low-end 8-bit chip which is very slow.

Power Supply for the Parking Heater

In most cases the parking heaters use the same power source as that of the motor vehicle. Normally, this power system has additional safety measures which ensure the parking heater only works within a specific range of voltage.

For instance, a situation whereby the power voltage goes above or below a specific range, it will automatically turn off the parking heater.

Of course, it will display an error signal before turning off. This is also the work of the control system.

When we were discussing how a parking heater works, it was quite clear that fore an ignition to start, there must be an electric signal. This is mainly for the fuel operated parking heaters.

On the other hand, for electric parking heaters, they use a power supply to heat either water or air. This makes it a critical aspect of the parking heater system.

Fuel Tank

This is a critical component for fuel operated parking heaters. That is, for gasoline parking heaters or diesel parking heaters.

Depending on the design of the fuel operated parking heater, it may use either the fuel from the main tank of the vehicle or an independent source.

white fuel tank

A white fuel tank

Well, the design of a parking heater fuel tank is not different from the ordinary ones we know – they are virtually the same. However, the pipeline to the parking heater has some special features that make them unique.
Some of the key components of a fuel tank include:

  • Pipe which transports fuel to the heater
  • Filter, it removes and debris or particles present in the fuel. This ensures no contaminants enter the pump and heater system.

Of course, these components work alongside other parts of the parking heater system such as fuel suction system, pipe clamping mechanism, connectors and joints.

Parking Heater Fuel Pump System

It is the component of parking heaters that ensure sufficient amount of fuel flows from the tank to the combustion chamber. This is a small component yet it plays a crucial role in the parking heater system.

parking heater fuel metering pump

A parking heater fuel metering pump

Fuel metering pumps come in a wide range of designs and configurations depending on the suction action and voltage supply.

Generally, a fuel pump system may have the following key parts:

  • Fuel filter
  • Pipes/fuel line/fuel pump connector/fuel hose; they allow fuel to flow from the tank through the pump and to the heater.
  • Pipe and fuel pipe clamp; holds these components in place to prevent unnecessary vibrations that may interfere with the flow of fuel from the tank to the parking heater. You can also add a fuel pump holder to this list.

Another component that plays a critical role here and closely related to these is the fuel standpipe. It is the fuel stand pipe that ensures fuel reaches the combustion chamber of the parking heater from the tank.

Parking Heater Blower

Blower plays an integral role in both fuel operated parking heaters and electric parking heaters.

In the case of gasoline/diesel air parking heaters and electric parking heaters, it is this blower that sucks air from the external environment then pushes it through the system.

Air enters the parking heater system from one end when cold and leaves through the opposite side when hot.

Parking heater blower system

Parking heater blower system

In air parking heaters, it is called the hot air blower. You can see its exact location in the image above (first image in this chapter).

Another important blower is the combustion air blower. This combustion air blower is in the inner section of the parking heater.

Exhaust System

Whenever fuel and air mixture burns, the final products include heat and exhaust gases/waste. The design of parking heaters is such that these gases can leave the combustion chamber through the exhaust system.

parking heater exhaust system

Part of exhaust system

Again, you can see the position of the exhaust system from the above image.

There are various sections that make up the exhaust system and they include:

  • Exhaust silencer; it reduces excess noise whenever the parking heater is working.
  • An Exhaust pipe/tubing; a pipe through which the exhaust material leaves the combustion chamber of the parking heater.

Others may include joints or clamping mechanism to support the exhaust tubing.

Air Inlet and Outlet of Parking Heaters

For fuel operated parking heaters, air plays an integral role during combustion. That is, combustion will only take place when a mixture of air and fuel is present alongside ignition mechanism.

Again, for air parking heaters, you need air to heat the passenger compartment among other components.

air flows in parking heater components

How air flows in parking heater components

Below are critical parts of parking heaters that form the air inlet and outlet system:

  • Air intake silencer; it purifies air to the combustion chamber besides reducing noise due to intake systems. Furthermore, it prevents wasps from nesting within the air system of the parking heater.
  • Air intake grill; it is on the extreme end of the system where it protects the blower impeller from damage by objects that may come into contact with it. Stray objects may damage the impeller resulting in insufficient air flowing into the system or failing to rotate completely.
  • Air outlet; once air enters the parking heater system, it will definitely leave and this is why an outlet is a necessity. The hot air leaves the parking heater system through the outlet and is then blown to different sections of the car.
  • Air ducting system; it helps to direct hot air to specific direction where it should perform various heating processes.

Apart from the different parts mentioned in this section, others may include:

  • Nylon ties for fixing cables
  • Wires; to connect various electrical components such as a heater to the power supply, sensors to controller and control panel, LED alarm light/sound, etc.
  • Mounting plate for fixing the heater during installation. These may include mounting gasket and bracket.

From this section, it is quite clear that parking heaters have very many components. For instance, in this section alone, there are more than 21 parts and components.

With this in mind, we can now move to another critical segment of this complete guide to parking heaters and this is the installation process.

Let’s look at how you can install parking heaters within the shortest time possible.

Chapter 7

Parking Heater Installation: How to Install a Parking Heater on Your Vehicle

parking heater installation

In this chapter, you are going to learn how to install a fuel operated parking heater. This is a simple process that you can do on your own.

All you need to do is follow the instructions in the technical manual.

Even before we go to the details of this process, I want you to watch this 20-minutes video. It explains how to install a VVKB Diesel Air Parking Heater.

Now, this installation process will also focus on a fuel operated air parking heater. You can use the process to install the parking heater in trucks, cars, marine systems, vans buses, etc.

You will learn more about these applications later in chapter 9.

For now, let’s dive right into how to install a parking heater in your vehicle:

Step 1: Verify the Packing List from the Parking Heater Manufacturer

To avoid instances where you can find yourself stranded because you do not have certain parts, it is important that you verify every component. This will ensure you check every specification alongside identifying every component.

Parts and components of parking heaters

Parts and components of parking heaters

In most cases, the parking heater manufacturer will pack this accessory with a manual. So, use this manual to physically identify and sort out all components.

This is what I mean:

parking heater manual

Parking heater manual, heating unit and packaging box

In addition to these, you must have the necessary tools and accessories that you will use during the installation process. Parking heaters do not come with such tools.

The tools may include:

  • Fastening tools such as screw drivers, pliers, spanners, etc.
  • Cutting tools such drill, saws, etc.
  • Welding accessories; this is in case you need to install it on a platform or place of your choice

In short, the number of tools and accessories will depend on where you intend to install the parking heater.

As you check the packing list, you should be able to identify the following parts (I hope you can remember our discussions in chapter 6):

  • Heater
  • Self-drilling screws
  • Fuse
  • Fuel pump, filter, pipe joint, pipe clip and pump clip
  • Air inlet pipe and filter
  • Gasket
  • Exhaust pipe
  • Protective cushion
  • Washer and nuts
  • Oil suction pipe
  • Cables
  • Control panel/control switch/control receiver or GSM receiver
  • Wiring harness/connector wires
  • Reducing T and pipe joints
  • Fuel pump leading wire
  • Air inlet and exhaust pipe clamps

NOTE: Some of these parts may vary depending on the model of your fuel operated parking heater. This is why you must do this assessment using the technical manual that comes with the parking heater.

Once you finish the part identification process, it is now time to proceed to the next step:

Step 2: Identify Where to Install the Parking Heater

You must identify convenient place to install various components of the parking heater.

These should include where you intend to install major components of the parking heater such as:

  • Heater unit; there should be enough space around the unit. If possible the fuel line and pump should be such that fuel flows upwards to the parking heater unit.

Remember, you will have numerous connections to the parking heater unit so the space must be enough.

  • Fuel tank; you can mount it vertically and the distance should be no more than 1.2m.
  • Control unit should be in a position that is easy to see and operate.
  • Air inlet and outlet should be at least on two opposite sides. This is to avoid instances of hot air getting into the parking heater unit again.

After identifying the right location, you can go ahead to begin the parking heater installation process.

Step 3: Prepare Parking Heater Ready for Installation

First, before you begin installing the parking heater unit, try turning the impeller to ensure it rotates freely and smoothly. By any chance it does not rotate freely you can adjust the impeller gap.

After identifying the exact location where you intend to install the heater unit, it is now time to begin the actual process.

First, put the mounting plate on the exact place where you intend to install the parking heater then mark the out these holes:

Mounting plate for the parking heater

Mounting plate for the parking heater

Then use a drill to make the holes. These holes include sections for:

  • Fasteners
  • Air inlet
  • Heater exhaust
  • Fuel inlet

As a rule of thumb, the holes should be slightly oversize to take care of the pipe fittings.

Even as you prepare this place, you should ensure that the air inlet and exhaust are free from any barrier.

As a general rule, you can leave a space of about 15 cm around the parking heater unit.

Now, you can install the sealing gasket then the mounting plate and use nuts to fix the two in place. It is this gasket that will prevent any possible leakage of exhaust.

Where to install the gasket and mounting plate

By the end of this process, you should have this:

Fastening the gasket and mounting plate

Fastening the gasket and mounting plate

Now, with the parking heater in this position, you can move to the next step:

Step 4: Now Install the Fuel Pipe, Exhaust Pipe and Air Duct Pipe

As you can see in image 2, we have three holes for fuel, air in and exhaust. To make the parking heater installation easier, you can fix these components first.

Now with the parking heater still in that position, you can do the following:

  • Fix the fuel pipe

The process will depend on the design of the parking heater fuel pipe. However, for the case of VVKB Diesel air parking heater, you fill first fix a black fuel pipe and secure it in position by tightening the clamp.

After tightening the black pipe, you can now plug in the white fuel pipe and secure it in place using a clamp. By the end of this process, you will have a continuous pipe (white and black) that will take fuel to the parking heater.

  • Install the exhaust pipe

Inert the pipe in the section with mark exhaust and clamp it tightly in place just like the fuel pipe.

  • Air ducting pipe

Go ahead to fix the air ducting pipe. Of course, like the other three, you will secure it in place using the clamps.

By the end of this process, this is exactly what you should have:

parking heater sections with appropriate pipese

All the three sections with appropriate pipes

Now, you can go ahead to install the entire structure in place. That is, the exact location you had intended to install the parking heater unit.

The parking heater should be in a horizontal position.

Let the air inlet, fuel inlet and exhaust pipes pass through the holes you had drilled earlier and mount the parking heater system in its position using bolts and nuts.

Now, this marks the end of our first process. You can now proceed to step 5 of the parking heater installation process.

Step 5: Fix the Inlet Air and Exhaust Pipes

Whenever you are directing the inlet air to support combustion and exhaust, you should take precautions to avoid instances of the exhaust reentering the system.

In most cases the inlet air and exhaust pipes will bend outwards and downwards from the parking heater.

Again, as you bend these pipes, the sum total of the angles made by each pipe must not exceed 270°. Besides, the openings must not face towards the direction in which the vehicle will be moving.

You can summarize all these in the images below:

install inlet and exhaust pipes

Comparing how to install inlet and exhaust pipes

At any given instance, the position of these pipes should be such that no slurry or particles can block the flow. They must be free from snow or water.

Furthermore, when the parking heater is working, the exhaust pipe tends to have a high temperature. Remember, all its contents come from the combustion chamber.

Therefore, you should install it away from flammable or substances with poor thermal resistance.

For the exhaust pipe, you will fix the extreme end using the appropriate clamping mechanism to ensure that it does not vibrate or move when the vehicle is in motion. That is, clamp it about 0.15m from the furthest end.

Again, the tip (where exhaust gases leaves) should be about 90° to the ground. In case the exhaust pipe passes where one can get in contact with it, you must clad it.

In addition to these, you can also install and exhaust silencer just before the last section of this pipe. It should be like this:

parking heater installed with exhaust silencer

On the other hand, you should clamp the inlet air pipe on the surface of the vehicle. It should be a position that fresh air can flow freely into the system.

At the extreme end of the inlet air pipe, you will then fix the air filter and tighten it.

Step 6: Install the Fuel Tank

If possible you should mount the fuel tank vertically. In most cases, whenever you are installing the fuel tank, its position should not be extremely lower than that of the parking heater.

Below is a summary of how the connection from the fuel tank to the heater should look like:

parking heater fuel tank connection

Connection from the fuel tank to the parking heater

Where 1-fuel tank, 2-fuel extractor, 3 – fuel pipe connector, 4- fuel filter, 5 – fuel pipe, 6 – fuel pump and 7 fuel damper.

In most cases, if the system comes with a fuel tank, then there is always no need to use a fuel stand pipe. Simply make a hole at the bottom of the tank and use its accessories to connect it to the fuel pump.

You can go ahead to fix the fuel pipe and then clamp it after, which you will insert the white fuel pipe and clamp it.

This now leads us to our next stage.

Step 7: Install the Fuel Filter

As a rule of thumb, you should install the fuel pump close to the fuel tank. It should either be at a horizontal level or slightly slant upwards to the pump.

By doing so, it will be easier to discharge the air in fuel pipes.

From the fuel tank, we move to the fuel filter.

The arrow in the filter must point up and be in the direction of flow to the fuel pump. Here is how to go about fuel pump installation process:

  • Cut the black fuel pipe, fit to the white pipe and clap them together.
  • Fit the black fuel pipe to the filter and clamp it

Fixing fuel filter

  • Again, cut the black fuel pipe, insert on the opposite end of the filter and clamp
  • Then insert a white fuel pipe to the black pipe and clamp

By the end of this process, you will have this:

complete installation of fuel filter in the pipeline

A complete installation of fuel filter in the pipeline

Remember, at every stage, you should clamp the fuel pipe on the vehicle to eliminate any circumstances of sagging in the pipeline.

Now, from the filter, you can install the fuel pump.

Step 8: Install the Fuel Pump

At about one meter from the oil filter, cut the white fuel pipe, insert the black one and clamp the two together. Now, insert the black fuel pipe in one end of the pump as shown below, then clamp the two together.

parking heater fuel pump

Tighten the parking heater fuel pump in place

Next, insert the fuel pump bracket as you can see below:

Parking heater fuel pump

Parking heater fuel pump

You can now fix the fuel pump in the vehicle. Remember, the fuel pipe from the pump to the parking heater unit should flow uphill.

Now you can connect the fuel pump to the heater. The procedure is still the same:

  • Insert the black fuel pipe to the white fuel pipe from the parking heater unit and clamp the two.
  • Insert the clamp to the black pipe and connect it to the fuel pump outlet and clamp the two.

By doing so, you should have the following:

fuel pipe line installation

Final installation of the fuel pipe line, inlet air and exhaust

Let’s have a quick reminder of what you have achieved at this juncture:

  • Fixing the parking heater to the vehicle unit
  • Connecting the parking heater unit to the fuel system via the filter and the pump
  • Installing air inlet pipe and connecting it to both air filter and parking heater unit
  • Connecting and redirecting the exhaust via the silencer and to the parking heater unit

Now let’s quickly finish on what is remaining:

Step 9: Connect the Hot Air Outlet

You can now fix the hot air ducting system. Its work is to direct air to other parts of the vehicle.

parking heater duct system

Hot air leaving the parking heater through the duct system

Simply insert the duct system to the hot air output section of the parking heart unit then clamp it. You can direct the hot air to specific areas within the vehicle.

Having fixed all the piping systems and other components, the parking heater is almost ready.

Step 10: Fix the Electrical System

The design of these cables allows for easy installation. That is, similar cables have unique design thus you can easily know where to fix them.

All you should do is fix similar cables together:

Connecting parking heater cables

Connecting parking heater cables

Press the button on the side to connect or disconnect the cables. In case the cable is very long, simply roll it nicely.

Next, fix the plug of the controller:

parking heater controller plug

Parking heater controller plug

Now, you can connect the fuel pump as shown:

Parking heater fuel pump power plug

Parking heater fuel pump power plug

You can see the three plugs are completely different, hence making identification and installation easy and simple.

With all these in place, now connect the parking heater to the main power source. Again here, you must pay attention to the color coding.

Cables to the main source of power

Cables to the main source of power

You must connect the two to the battery or main source of electric power. So, never connect them to a cigar lighter – the system will not work.

At this stage, it is important to note the following:

  • Ensure you connect the cables/connecting wires firmly to prevent sparks or low voltage conditions. The parking heater system may not work under such conditions.
  • Connect the positive cable directly to the main battery to ensure the starting voltage is in normal position. The cross-section of this wire must not be less than 2.5 mm2.

Basically, all these steps, from step 1 to 10, illustrate the basic parking heater installation procedures. Remember, for the purpose of this illustration, I was using VVKB Diesel Air Parking Heater.

The procedure is not different in other models of parking heaters. You can still use this as a guide.

Finally, it is now time to test the parking heater for the first time. You should take note of the following:

  • Switch on control panel to automatic pump mode or simply start the parking heater.

Switching on the parking heater

Switching on the parking heater

You can press the power button for about 2 to 3 seconds and the heater will turn on. On the display screen, it will show A00 which is the ventilation mode so you should turn to A01, which is the heating mode.

Wait until the pipe is full of fuel and connect it to the parking unit fuel inlet. Through this, you will remove air in the fuel piping system.

Now back to our switching mode A01. During this process, you may start the parking heater machine for about 3 to 4 times.

This will depend on the length of the fuel pipe and time it takes for the fuel to fully flow in the entire system as it exports air.

Apart from the above parking heater controller, the system has another controller with additional functionalities.

VVKB controller

VVKB controller

These are what you can achieve with this parking heater control system:

  • Pressing it for two seconds turns on the heater (you can see ON/OFF button)
  • For ventilation mode, press the power button twice
  • In the heat mode, the unit will start heating
  • You can switch between auto mode and hand operated mode using the button indicated “auto”. This allows for temperature adjustment.
  • On the display, you can see the ambient and setting temperature.

In short, with this controller, you can change the speed of the fan, set temperature and time the heater. This makes it a handy and versatile accessory.

At this juncture, when you follow this parking heater installation guide alongside the technical manual of the machine, going about this process yourself should not be a problem.

Now, what should you do whenever a parking heater is not working optimally?

Here is a must read section of this parking heater guide.
