A Detailed Introduction to VVKB Engine Heaters


Why do you need an engine heater?

First, it is important to understand how an engine functions under different temperature conditions.

When temperatures drop to 5 degrees Celsius (41 degrees Fahrenheit) the fluidity of normal engine oil begins to deteriorate.

When this happens, the engine oil is unable to quickly and effectively lubricate the main parts of the engine when cold starting. This lack of lubrication is hard on the engine and can lead to premature engine wear.

When the temperature drops to 5 degrees Celsius (41 degrees Fahrenheit) the fluidity of normal grade engine oil becomes even worse and the metal parts within the engine begin to suffer from the effects of thermal expansion and contraction due to temperature differentials between parts.


Starting the engine at this low of a temperature will not only begin to cause wear to engine parts, but will also increase fuel consumption and the emission of pollutants.

When the temperature drops to 0 degrees Celsius(32 degrees Fahrenheit) only low viscosity engine oil should be used. The thermal expansion and contraction stresses on the engine is further increased and the batteries reactive chemical processes and power begins to decline.

When the temperature drops below -10 degrees Celsius (14 degrees Fahrenheit) low viscosity engine oil begins to also suffer from fluidity problems, and the thermal expansion and contraction of engine parts is even further increased causing even greater engine wear.

The battery’s power is also decreased so much so that it can begin to have difficulty sending sufficient power to the starter to rotate the camshaft. This often requires multiple attempts from the driver to start the vehicle.

If you continue to cold start the vehicle under these conditions you will begin to notice a significant increase in fuel consumption.

In addition, every time you attempt to start the vehicle and fail, there will be black incompletely burned fuel that is discharged into the air with the exhaust gas causing pollution to environmental air quality.


Under normal temperature conditions, it only takes the engine a short amount of time to get up to efficient operating temperatures.

However, under low temperature conditions it may take more than 10 for the engine to reach proper operating temperature and provide heat to the passenger cabin using a standard car heating system.

Drivers in this situation either resort to driving with bulky heavy winter clothing which inhibits reaction times and comfort, or they start the car and let it idle in place for 10 minutes in order to let the engine temperature rise and the heater to warm the passenger cabin.

Repeatedly starting the engine in this fashion increases both fuel consumption and engine wear.

When the temperature drops to -20 degrees Celsius or below (-4 degrees Fahrenheit) the thermal expansion and contraction effects on engine parts becomes quite severe.

Some engines (especially diesel engines) will not be able to operate normally if auxiliary heating equipment is not employed.

Battery power becomes severely decreased without aide from an auxiliary heating device, and after several cold start attempts there may exist insufficient power to start the engine anymore.

Even if the engine is successfully started, the great degree of thermal expansion and contraction within it will cause severe wear and tear on engine parts.

This is one of the reasons for the high failure rate of vehicles driven in the winter.

By simply installing an engine heater all of these negative effects from cold starting can be mitigated. The heater will allow the engine to quickly reach operating temperatures permitting oil to efficiently flow throughout the engine and lubricate the engines pistons and piston rings.

In addition, it will reduce fuel consumption and pollution on start up and the wear and tear that occurs from repeatedly cold starting a vehicle.

The benefits of installing an engine heater can save drivers thousands of dollars in engine damage.


All in all, that’s why we need an engine heater or engine block heater to warm up the engine at low temperatures to protect the engine from much wear and also save much cost.

After heating up the engine, the engine temperature will rise, and then the oil will thaw; the oil will return back to normal fluidity, and the cooperation between the engine parts such as the engine piston and the piston ring will start to work normally again.

Meanwhile, the engine start is restored to work normally too.

In this way, with the engine heater, customers can save a lot of fuel consumption and reduce a lot of exhausted gas pollution.

Moreover, the failure rate of the vehicle start in winter will greatly reduce.

Using engine heaters can help drivers save more than $5,000 per year including various vehicle costs.

So in the following, we will have a brief introduction of different types of engine heaters.

Engine heaters can be roughly divided into three categories:

First one is the fuel heater, or we can say fuel coolant heater or coolant heater.

Fuel Coolant Heater (Coolant Heater):

coolant heater for diesel engine Outlet

It’s a kind of heater that heats up the engine’s coolant by burning diesel.

VVKB Apollo-C series

The advantages of the coolant heater is that it can work without an external power supply and it’s very fuel-economical, which only consumes 0.5L per hour.

The minimum power of the coolant heater is 5 KW, a large amount of heat can be generated, so it works better and is more efficient than the parking heater series VVKB Apollo-V series.

When the coolant heater is working, the engine and the entire circulation system can be heated to more than 30 degrees Celsius.

In this way, when turning on the vehicle’s own heating system, it can provide enough heat for the driving cabin as well as sleeping cabin, completely solving the problem of the heating issue when parking in the cold winter, and can keep providing heat and warmth for the engine.

The VVKB coolant heater Apollo-C series have passed CE, RoHS, FCC certification.

We select advanced technology and good raw material for parts to support the quality of our coolant heater. The heater works with 32-bit chip control system, making the operation smoother and faster.

The main heater and the control panel are using CAN communication technology, which makes every working step more accurate.

The motor speed reaches 9000 revolutions per minute. Using a spiral exhaust pipe, the working noise can be greatly decreased.

The rated voltage of VVKB Apollo-C series is 12V or 24V, while their rated power varies to suitable for different kinds of sizes and to achieve different requirements from different customer.

Therefore, VVKB Apollo-C series have 5KW, 9KW and 12KW.

VVKB Apollo-C series is suitable for a wide range of vehicles, such as trucks, construction vehicles, large tractors, etc.

Besides warming up the engine parts and vehicle cabin, VVKB Apollo-C series can also heat up water, so can provide hot water for people to daily use.

exhaust pipe of parking heater

The pipes and radiators can be connected with a heated liquid to provide heat to the room or any special space.

The second type of engine heater is the engine heater with the electric heating tube.

According to different structures and designation, this kind of engine heater can again be divided into following three types.

Auxiliary circulating engine heater with built-in pump.

VVKB engine preheater Titan-P1, P2, P3, P4, P5

Here we have VVKB heater products — VVKB Titan series

They are kind of engine heaters with built-in pumps, those we can also call them engine preheaters.

It needs to use an external power supply.

When the electric heating tube is heating, the built-in water pump can deliver the heated coolant to the engine to provide heat to the engine.

To guarantee the safety issue, the VVKB engine preheater Titan series also has a temperature control system in the heater.

When the temperature reaches 65 degree Celsius, the built-in pump will stop working and the heating function of the engine preheater will also stop working, while when the temperature is below 45 degree Celsius, the built-in pump and the heater will automatically start to work again.

However, considering that some customers need the pump to work all the time, VVKB can also provide the customers with a semi-customized heater that can keep the built-in pump working all the time.

VVKB engine preheaters all have passed TUV, CE, FCC, RoHS certification.

Compared to other types of plug-in engine heaters, VVKB engine preheaters warm up the engine faster, have higher heat efficiency and also is much safer.

Thermal cycling engine heater (VVKB engine heater Titan-P6)

titan-P6-winter-car-engine heater

VVKB winter car heater Titan-P6 is different from other VVKB engine heaters. It does not have a built-in pump, so it is completely thermally cycling one.

It has a check valve design to prevent heated liquid from flowing back. But VVKB winter car heater Titan-P6 is also somewhere similar as other VVKB engine heaters— it also has a temperature sensor inside the heater.

When the temperature reaches 65 degrees Celsius, the heater will stop working automatically. When the temperature is below 45 degrees Celsius, it will automatically start working again.

This temperature sensor design is to guarantee the safety when using the heater.

By using the electric heating tube as heating elements, VVKB winter car Titan-P6 can warm up the engine quickly with high heating efficiency.

Embedded heater (VVKB engine heater Titan-P7, P8)

This kind of VVKB engine heater is just installed on the engine block, which directly heats the coolant.

It has a simple structure, without the built-in pump, no outer housing, no temperature controller inside the heater, and it usually has low rated power, such as400W.

The third type of engine heater is PTC engine heater.

VVKB engine heater Titan-B series uses PTC as the heating element, and it also have the built-in circulation pump. PTC heating element itself is the temperature sensor.

When the temperature reaches what we have set, the PTC heating element will automatically reduce the power; thus the heater will turn into lower power to work.

As we can see, PTC engines will become the new trend in engine heaters field. VVKB has been developing PTC heating elements in the automotive field since 2010 and successfully designed Titan-B1 engine heater in 2016. It now has obtained EU patent, German patent and TUV certification.

At present, VVKB is again investing a lot in PTC field, especially studying with PTC’s performance and applications.

VVKB has already designed a new engine heater that is now undergoing the working test and maybe will launch to the market in 2019 or 2020.

We are confident it can revolutionize the production of automotive engine heaters.

In the following several paragraphs, we mainly introduce different models of VVKB engine heaters.

1. VVKB Titan-B1 Engine Preheater.

engine block heater timer bracket mounting position

During the 20 years of engine heater production and sales, VVKB has accumulated a lot of experience and obtained a lot of customers’ needs and feedback from the market.

According to those requirements and feedbacks from different customers, VVKB starts to focus more on the products itself, trying to make more progress to improve it.

At the same time, VVKB has also seen the irreversible impact on the environment from people’s production activities.

Since 2012, VVKB has been looking for new heating elements with better heating efficiency and more environmentally friendly that can replace the traditional heating tubes.

At the beginning of the selection, VVKB found that there were many materials that can replace original electric heating tubes.

However, with a depth of research and lots of test, we found that most of the alternative materials are not competent.

They can be easily affected or broken under the harsh environment. In an accidental situation, VVKB engineers were exposed to PTC ceramics and start to test its performance and function.

After several times discussions among engineer, they reach an agreement that PTC ceramics can be used to replace the original heating tubes in engine heaters.

After four years of research and practical testing, at last, we launched a new engine heater called VVKB Titan-B1 engine preheater in 2016.

VVKB Titan-B1 engine preheater uses PTC ceramics as heating elements, which can heat up the engine parts so quickly.

With the built-in magnetic water pump, VVKB Titan-B1 engine preheater can greatly improve heat efficiency, and reduce the heat loss.

PTC, as the heating element, has a special characteristic– after reaching the certain temperature, the resistance of the PTC ceramic will be greatly increased.

In this way, the heater power decreases.

And because of this characteristics, it does not require a built-in temperature sensor anymore.

And this simple structure makes VVKB Titan-B1 engine preheater service life be greatly extended. VVKB Titan-B1 engine preheater has already passed TUV, CE, RoHS, FCC certifications.

We will not stop our step, VVKB engineers have still been developing products that are more in line with user habits and requirements.

It is expected that in 2019 or 2020 that VVKB will introduce a new engine heater, allowing users to enjoy better and better warmth of VVKB.

Based on the VVKB’s more than 10 years of market experience and feedback from customers, and some shortcomings from the former products, VVKB design team improved and designed the new VVKB Titan-P3 diesel engine preheater in 2008 with reference to the working principle of the heating system on rice cooker.

The heating element of VVKB Titan-P3 diesel engine preheater is die-cast in a monolithic aluminum ingot, which can effectively increase the service life of the heating element.

What’s more, VVKB Titan-P3 diesel engine preheater has inherited all advantages of VVKB other engine heaters — with built-in water pump as well as high quality aluminum outer casing.

In order to control the temperature more precisely and accurately, we have designed two separately thermostat control/ temperature sensor on the VVKB Titan-P3 diesel engine preheater, to make the operation more reliable and safe.

That means once the first temperature sensor falls faulty, the second one will keep working.

The 90 degrees angle between the water outlet and the inlet allows VVKB Titan-P3 diesel engine preheater to be easily placed in the compact engine compartment.

The small and compact mounting brackets allow the heater to be conveniently secured and fixed in the proper position.

This makes the installation of VVKB Titan-P3 diesel engine preheater very time-saving and also labor-saving.

diesel warmer

Market and customer needs and requirements are always the source of motivation and creativity for VVKB’s progress.

According to the use of the VVKB Titan-P3 diesel engine preheater for nearly one year, many customers said that although the design of the inlet and outlet 90 degrees is very reasonable, for large trucks, the inlet and outlet of the engine heater should be in a straight(180 degrees) line.

Therefore, this allows the coolant to flow more smoothly. Based on this feedback from customers, we launched the Titan-P4 diesel engine warmer in 2009, which has also inherited all the advantages from VVKB Titan-P3 car diesel engine preheater : high quality of materials, die-cast electric heating elements, precise double separately ceramic temperature sensor, completely TUV-compliant cable sheath and wire cross-section as well as reliable plugs.

Meanwhile, about the plig, we now have a European standard plug, American standard plug, and Australian standard plug. We also accept to customize a different kind of plug styles according to the needs of the customers.

6. VVKB Titan-P5 Truck Block Heater

truck cab heaters

In the winter of 1997, many users called VVKB technical department to add a water pump to the VVKB Titan-P6 winter car heater to assist the better operation of the engine coolant.

According to the feedback from the users, VVKB technical department simulated the working scenario of VVKB Titan-P6 winter car heater.

Based on VVKB technical department’s on-site test of the heater and the water pump. When with water pump, it takes much less time to heat the same vehicle engine up to the same temperature, and the thermal efficiency is significantly improved.

Thus, VVKB technology department believed that adding a built-in water pump to the engine heater is a wise choice.

Then in the spring of 1998, all efforts were made to develop a new engine heater with a built-in water pump. This action can be said to be very crazy at that time. At that time, people thought that it’s good enough for engine heater to solve the temperature transfer problem through the thermal circulation.

And people are willing to spend this time on waiting for the heater to warm up. As factories, they don’t need to spend any more time and money on developing an engine heater with a built-in pump that doesn’t seem to work. However, VVKB is committed to providing users with products that conform to their need.

And also protecting the environment and making all VVKB products more energy efficient are always VVKB’s pursuit. According to the shape of the motor and the structure of VVKB Titan-P6 winter car heater, VVKB design group finally launched VVKB Titan-P5 truck block heater after half a year.

VVKB Titan-P5 truck block heater has already been selling well on the market more than 10 years, because it solves the pain points of VVKB Titan-P6 winter car heater, and help more than 1 million truck owners to solve the winter engine start issue.

They will go through CE, RoHS, FCC certifications.

Engine Heater: The Definitive Guide

Cold starting automotive engines will put you in these devastating scenarios:

  1. High fuel consumption
  2. Emission of harmful gases to the environment
  3. Increase engine wear

The cost will be quite high,and your engine will be extremely inefficient.

The good news?

Installing an engine heater will solve all these problems.

Because it offers a cost-effective, reliable and efficient way to warm your engine during snowy or cold weather.

It will quickly bring your engine to normal operating temperature.

Of course, there are many engine heaters out there – but, which one should you buy?

That is what you’re going to learn here.

Let’s get to that.

What is Engine Heater?

An engine heater is a device that warms up the engine and other engine fluids (depending on design), before starting it.

Ideally, it makes it easy to start engines, improve efficiency, reduce emissions, while reducing wear and tear.

I will take you through the various benefits of engine heaters later – keep reading.

Tractor engine heater

Engine heater

Currently, engine heaters come in a range of shapes and designs.

Furthermore, they feature modern technologies, allowing for a short warm-up and efficient heating.

As a result, they get rid of all engine wear that might arise due to cold starts.

car block heater

Engine heater design 1

portable block heater

Engine heater design 2

From experience, the best engine heater should guarantee better fuel saving and practically soot-free ignition of engines.

In a nutshell, the design of any engine heater will depend on your unique application requirements.

That makes reviewing technical specifications of engine heaters an important aspect.

We’ll come to that later.

But first, look at this:

Why You Need Engine Heater

As I had said, block heaters play an important role in automotive engines.

It is even critical when the surrounding environment is extremely cold.

Heating car engines

Heating car engines

Now, this is why you should buy an engine heater:

1. Saves you from Cold Starting the Engine,i.e. “Stressing” the Engine

Starting very cold engine stresses it, hence high wear.

Normally, when it is cold, the oil becomes thick.

Thicker oil increases the amount of “work” needed by starters to turn crank engines.

This results in longer starting time.

Also, when oil becomes too thick, it cannot flow freely to various parts of the engine.

As a result, lubrication will not be sufficient.

When that happens, those parts scrape against one another while starting the engine.

It is a scenario that is common when there is no lubrication.

Again, if the engine runs on cold components that haven’t been warmed up and expanded to the ideal size, they can get damaged.

As you can see, block heater reduce engine wear by enhancing lubrication and easy starting.

2. Helps to Warm Up Your Cabins Quickly

When your car has been in the cold, it can be cumbersome to start the car engine.

It is at this point that you need to warm up the engine.

With engine coolant fluids after warming by block heaters, your cabin will have warm air drawn in after you start it in the morning.

3. You’ll Save Fuel

Idling engines consume a lot of fuel.

However, with an engine heater, you can avoid idling of the engine.

This is because it will warm up the engine faster.

Remember, most people leave their vehicle engines in the idling state for them to attain the right staring temperature.

4. Helps to Keep your Battery Stronger

Engines that are cold can take much time to crank-up.

During this time, the engine can drain or discharge starter battery.

5. Reduces Exhaust Emissions

exhaust pipe of parking heater

Block heaters help to reduce exhaust emission when starting the engine.

Remember, at the normal operating temperatures, engines produce low emissions.

Therefore, an engine heater will quickly make it operate at its normal operating temperature.

6. Reduce Condensation in Engine Sumps

Keeping engine warmer reduces the possibility of condensation in engine sumps.

Therefore, this will improve the performance of your engine.

7. Ensures that your Engine is always Reliable

In generators and cars, etc. engine block heaters increase the reliability of the engine.

In a nutshell:

An engine heater is a must-have accessory if you care about the efficiency of your engines.

But, you can only achieve this by choosing the right engine heater.

Now, what are the best types of engine heater for you?

And, by the way, most vehicles in extremely cold environments come with a block heater as standard equipment.

Still, if it fails or your vehicle doesn’t have a block heater, simple shop for a suitable one.

Types of Engine Heaters

I know there are many engine heaters available in the market.

Therefore, it is important to have your priorities right.

That is, choose a block heater that meets your unique requirements.

Now, depending on your unique applications, you can choose any of the following:

a) Coolant Engine Heater

Coolant engine heaters are an integral part of engine heaters.

The design of these heaters is such that they help to maintain a suitable operating temperature of the engine.

Even during downtime, you don’t have to worry about possible idling of the engine.

coolant heater for diesel engine

Coolant heater

With a good brand of coolant heater, your engine can deliver full power faster.

Coolant engine heaters depend on forced circulation or thermosiphon to pre-heat the engine.

In most cases, it helps to keep the coolant temperature at 32°C (minimum).

When you have a reliable coolant heater, your engine can take full load within a short time.

b) Circulating Engine Heater with Pump

Unlike the coolant engine heaters, these designs come with small pumps.

It is the pumps that help to circulate heated coolant continuously throughout the engine at a uniform temperature.

Titan-P3 Diesel Engine Preheater

Circulating engine heater with a pump

The uniform circulation of heat reduces possible hotspots on the heater hoses, seals or coolant life.

The design of the circulating engine heater with pump reduces frequent maintenance while extending the lifespan of the heating element.

c) Engine Heater without a Pump

Engine heaters without a pump work without the use of pumps.

block heater

Section of block heater

They work like bolt-on engine heaters.

This type works by having engines heated through direct contact.

Although it is very effective, this type of heater heats engines completely and doesn’t heat coolants directly like those with pumps do.

d) PTC Engine Heater

Positive temperature coefficient (PTC) is a new technology in engine heaters.

PTC Engine heaters are popular for their self-timing.

Therefore they cannot overheat, hence ensuring safety.

It automatically changes as per the environmental demands.

The PTC engine heaters have completely revolutionized the industry.

e) Electric Block Engine Heater

You can carry engine block heaters from a point to the other.

However, they work when you have them plugged into electrical outlets.

Electric block engine heater

Electric block engine heater

Block heaters do not come with pumps.

By warming the car engines, these heaters make starting simple and easy.

With these in mind, let me take you a step further and explore parts of engine heaters.

Parts and Components of Engine Heater

From the previous chapters, it is clear that an engine heater is an assembly of various parts and components.

These parts and components may vary from one engine heater to another.

In this section, you’re going to learn about some of the most common parts of engine heaters,

Let’s dive right in:

Engine heater system

Figure 9 is an overall layout of the engine heater.

Still, I can take you a step further to dismantle the engine heater so that you may see the internal components.

With all that in mind, let’s now discuss some of these components:

1. Combustion-air fan unit

This component helps in supplying air for the process of combustion.

Depending on the design of engine heater, a combustion air fan may have:

  • Heater label type
  • Engine and impeller
  • Control unit with plug-in contacts for electrical contacts
  • Opening for combustion-air connection piece as well as combustion air pipes

2. Diesel or petrol burner

In the burner, the processing of fuel-air mixture and the actual combustion happens.

The fuel directly flows into or through preheating chambers with an opened shut-off valve.

This is where first heating up takes place.

After it exits from fuel needles, it is atomized in venture nozzles through which actual air flows.

Always ensure you choose a heater with an appropriate burner.

Remember, your engine heater depends on it to warm up the engine.

With the wrong burners, there will be malfunctions and damages on the heater which will reduce its lifespan or service life.

3. Heat exchanger

The work of an engine heater is to transfer heat to the engine or the coolant unit.

Its efficiency determines how fast this accessory will warm up your engine.

In most cases, heat exchangers have both inner and outer sections.

Also, it may feature O-ring for an appropriate sealing.

4. Temperature and overheating sensor

Temperature sensors work by detecting coolant temperature within the heat exchanger of the engine heater mainly as an electrical resistant.

It is this signal that goes to the control unit of the engine heater – this is where processing begins.

It sends signals to the control unit on when to start and finish the engine heating process.

5. A circulating pump

Circulating pumps provides feed rates of coolants in cars or heater circuits.

You can turn on the circulating pump from the control unit.

For effective heating, it will keep working all through the whole operation of heaters.

6. Metering pumps

Metering pumps combine transport, metering, and shut-off systems to supply fuel from the tank of the car to heaters.

7. Solenoid valve

Not all heaters feature a solenoid valve.

A solenoid valve makes sure the fuel flows into combustion chambers at specific times in start-up phases.

After turning off heaters, solenoid valves prevent fuel from flowing into the combustion chambers.

8. Air bleed screw

It keeps the engine in place.

Without the air bleed screw, engine heaters cannot work as they should.

So always make sure it is tight.

9. Temperature limiter

It helps regulate the heating temperature by ensuring the process does not go beyond a specific threshold.

It helps to limit temperature and keeps in check.

So basically, it is a safety measure for an engine heater.

10. Flame detector

It is yet another important sensor that detects the flame to avoid any possibility of fire.

Thus, it is a critical safety measure.

11. Thermostat control

Some engine heaters may also feature a thermostat control.

It helps to regulate the heating process.

Remember, if you use heaters for a long period, the coolant hose may get broken.

Of course, it will be due to high-temperature levels.

It is for that reason that you need a thermostat control.

12. Exhaust pipe

portable parking heater exhaust pipe

It is a channel through which exhaust gases leave the engine heater.

13. Heating tubes

These are a channel which the fuel and other critical fluids flow through the engine.

14. Electric cord

For electric engine heaters, this cord is key.

These cords come in different lengths and sizes.

15. Coolant circulation system (inlet and outlet connection)

It is a system through which the coolant flows thereby heating the engine.

In short, these are some of the most common components of engine heaters.

By the way, have a look at this:

As a rule of thumb – always request for an engine heater product manual.

From this document, you will know all the parts and components of the engine heater you’re planning to buy.

With that, let’s move to yet another important aspect of engine heaters:

How an Engine Heater Works

As you have seen in earlier sections, there are many types of engine heaters.

Therefore, the working principle may vary slightly.

That is, it may involve varying procedures of heating engines.

In this section, the focus will be on the working principle that is common in most engine heaters.

Let’s get to that:

a) Electric Engine Heaters

These heaters require an external power source – electricity.

Here is what happens.

The engine heaters have a heating element which is in the engine block.

Thus, the heating element has an external cord, which you can connect to the external power supply.

Depending on the design, these heaters can replace one of the car engine’s core plugs.

Normally, the heating element is immersed in the engine’s coolant.

By heating this coolant, it will obviously keep the engine warm.

I am sure, you have seen cars cords that help to supply external electrical heat to the car engine heater.

Heating car engine

In most cases, these engine heaters do not have pumps.

However, these are those with pumps that help to supply the warm coolant throughout the car engine.

Apart from the electric engine heater, you can also opt for:

b) Gasoline or Diesel Engine Heater

Here, you don’t need an external source of power to heat the engine.

I consider this the most convenient – you can warm your engine anytime and anywhere.

Now, these types of heaters use either gasoline or diesel.

That is, you may run them on the vehicles diesel or gasoline fuel.

Here, the engine heaters burn either gasoline or diesel to produce heat that it uses to warm the engine.

It has a pump that transfers diesel or gasoline to the combustion chamber.

Of course, in the combustion chamber, both air and fuel mixes.

Once the mixture gets to a specific threshold, it ignites and burns to produce heat.

It then transfers this heat to the engine via heat exchangers.

Engine heater

In most cases, these heaters depend on thermosiphon principle.

That is – the engine heater preheats the engine coolant through convection.

The warm coolant will then rise upwards via the piping to the car engine.

As a result, it displaces the cold coolant, which will drop back down into the engine heater system.

This cycle will continue until your engine reaches a suitable temperature.

In a nutshell, the working principle of engine heaters depends on these two principles.

Of course, some heaters feature improved working principle for efficiency.

As a rule of thumb, always request for the engine heater technical manual.

It will help you understand your engine heater.

Let me take you through a critical step:

Engine Heater Installation Process

Most people wonder if it is difficult to install engine heaters or block heaters.

The installation process of block heaters is nothing complicated.

However, the process may vary slightly depending on the design and configuration of the engine heater.

For example, the simplest engine heater type is one that has an oil dipstick replaced.

Another type of engine heater, which is slightly complicated splices into upper radiator hoses.

It can be installed in a few minutes.

All you will need is a screwdriver.

The best engine block heaters have drain plugs replaced on the engine block bottom.

Some tools that you need before installation include:

  1. The right screwdriver
  2. Torque wrench
  3. Drain pan
  4. Tape measure
  5. Engine block heater
  6. Ratchet and sockets
  7. Felt tip pen
  8. Engine coolant and motor oil
  9. Silicone heat transfer grease

Below is a general instruction to consider:

Have your Vehicle Jacked Up

Deciding to work on a cold vehicle will safeguard you from having yourself burnt.

However, deciding to work on warm engines makes it quite easier to get rid of drain plugs.

This is mostly if they are made of unique metals than engine blocks.

Remember, engine heaters are designed in different wattages.

Always choose one that will meet your needs specifically and is ideal for your vehicle.

Have the front end of the car jacked up and take off the engine cover.

Drain the Engine

Depending on the specific equipment you use you will realize that the process will differ.

So make sure you refer to the engine heater manual always.

Now, this what you should do.

Go on by removing the clips that hold the radiator cover and the bolts that hold the radiator mounting brackets too.

Have a pan put under the engine and have the specific drain plug pulled.

This is mostly located at the engine block’s rear.

Remove the radiator cap to accelerate drainage.

Plug in the Heater

Pre-fit the connection between power cords and heating rods in case you need to have it done blindly in the future.

Have the male end of cords dropped into the engine compartment?

Lubricate rod or hole with grease up to the metal clip.

This shouldn’t be further than the metal clip.

Put the rod into the hole.

At times, fixing this may cause some resistance – implying, there is resistance due to air.

You can fix this by displacing it with extra grease.

Ensure the metal clip is facing the car’s rear.

You will hear a loud snap when heater slides into its right place.

Some types need to be tightened with wrenches to specific torques.

Have Power Cord Routed

Plug cord into rods.

Have wire run harness through engine compartments and out the front grill.

Have all other directions in the manual of the engine heater to help make installation simple.

Some points to note:

  1. Make sure you do not move any hoses or parts.
  2. Immediately cords are positioned rightly, have it secured with wire
  3. Try not to leave slacks behind first ties.
  4. Always have cords kept off engine manifold.

With all these in mind, you will have your car working perfectly.

It will also be fuel efficient.

Of course, this is a simple process of installing an electric engine heater.

You can watch this video:

It’s a simple process – right?

Note: Always remember the manufacturer’s engine heaters installation instructions.

You will find all that in the heater manual.

Now, on to another important segment.

VVKB Engine Heater

1. When should I install an engine heater?

In case you live in areas that are extremely cold, or temperature goes below normal, then install one.

It is the only sure way to quick start your engine without overworking or stressing it.

Besides, you will improve the engine’s efficiency and performance.

2. In what condition do you need to use engine heaters?

A. When your car has been parked for a long time outside at low temperature, starting the engine to have the crankshaft driven can be very hard. So you can use this car engine heater at this time. This is because of the cold-shrinkage of the car’s engine and the enhanced fuel viscosity.

B. The cold start will accelerate the wear of car engine. This will immensely enhance exhaust emission from the car. In the meantime, fuel consumption will significantly increase.

You can avoid all these by using engine heaters.

C. This car engine heater safeguards and warms up the car engine by heating the coolant. Through this method, the temperature of the engine rises, fuel viscosity reduces. This protects the car engine and makes hot starting possible.

3. What is the need for an inbuilt pump in engine heaters?

Heaters with inbuilt water pumps help in cutting down heating time.

It also helps to make heating very simple, fast and even.

4. What damages can occur due to forced circulation?

A forced circulation heater will act by applying heat that sends heated coolant to the head of the engine.

The cylinder head’s inlet temperature will be high even as the lower part of the engine remains very cold.

This is what makes the uneven heat of engine parts common.

It can greatly affect the engine itself and reduce the service life of the engine.

5. Why should an engine heater use a thermostat?

If heaters are used for longer periods, its coolant hose might be broken due to high-temperature levels.

You need a thermostat to regulate temperature.

6. Can engine heaters be used on trucks?


However, you should choose an engine heater with the right ratings.

For instance, an engine heater with 1200W can be too low for trucks.

So for trucks or heavy engines, you can go for 2000W or 3000W.

7. How can I ensure my engine is warm during winter months?

You can try the following – they are very effective:

  • Install engine heaters
  • Keep the fuel tank full
  • Ensure the battery of your car is kept warm.
  • Make use of fuel conditioners
  • Always park your car indoors.

8. How long do I have block heaters plugged-in?

A when you maintain a car well, it will not require too much plug-in.

It needs to be plugged in for two hours to warm up.

Also, it mostly takes 2 hours for cars to be cooled down after use.

So if you wish to drive again in these two hours, do not have it plugged-in.

9. Is idling advisable for cars?

No and Yes.

Well, it will all depend on the circumstances at hand.

However, you should know that idling may increase engine wear, fuel consumption, emissions, etc.

Again, don’t warm the engine by idling – you can install an engine heater.


As you can see, engine heaters are essential accessories.
