You will definitely purchase products from different diesel air heater manufacturers for comparison.

After receiving the samples, you will see that the appearance of these diesel air heaters will be very different.

The diesel heaters that look perfect in appearance, will probably be of better quality.

You also need to compare the accessories of diesel heaters.

We have prepared a detailed description of diesel heater accessories for you.

Let’s continue.


The accessories for diesel heaters

A diesel heater usually consists of around twenty parts. The quality of these parts is crucial, and will separate good diesel heaters from poor ones.

The diesel heater combustion motor assembly

Diesel Heater Combustion Blower Motor​

Diesel heaters use diesel fuel to warm up the cold air from the outside and blow it inside the cabin. The motor and its combustion chamber are where the magic happens, and are the most essential parts of any diesel heater.

The quality and efficacy of the motor will determine not only how much fuel it consumes, but also how noisy it is while working.

Your customers will want it to be as silent as possible.

You can read the following article to learn more about the diesel heater combustion motor assembly.

The diesel heater glow pin

Glow Pin

The diesel heater glow pins will make or break the diesel heater experience.

Many cheap Chinese diesel heater companies choose to install cheap glow pins into their diesel heaters.

These will work under normal conditions, however, when the outside weather goes sub-zero, you might find it hard to start the diesel air heater.

You should choose the Kyocera glow pins.

This company makes the best, field-tested glow pin, able to withstand even the coldest weather. And no power failure.

Diesel heater fuel pump

Fuel Pump

The fuel pump is an important part of the diesel air heater. It determines the efficiency of the diesel air heater operation and the fuel consumption of the diesel air heater.

When the diesel heater is working, the fuel pump will be a fixed frequency of beating and it will seriously affect your customer’s sleep quality.

Even with a rubber mounting bracket, the bouncing is transmitted through the frame to the entire RV.

You can choose the silent fuel pump, which bounces very little automatically. Here is the test video of the silent fuel pump, you can hardly hear the vibration of the silent fuel pump.

Diesel air heater heat exchanger


According to the working principle of diesel air heater, the combustion of diesel fuel will produce toxic exhaust gases such as carbon dioxide and carbon monoxide as well as sulfur dioxide.

Diesel air heaters are used in very little space and in a sealed space. In this space, there is no fresh air, and people may worry that the combustion exhaust gas may enter the car and affect people’s life safety.


This concern is well-founded.

The heat exchanger is produced by the aluminum die-casting process, a process that has the potential to leave the heat exchanger with trachoma.

Moreover, the temperature inside the heater is very high, and at high temperatures, the trachoma is likely to be corroded by toxic combustion exhaust gases, and combustion exhaust gases will enter the vehicle interior.


However, the products of regular diesel heater manufacturers will not have a trachoma situation.

Take the Vvkb diesel heater as an example.

When Vvkb heater engineers design the diesel air heater heat exchanger mold, they reserve the exhaust port for aluminum die casting. This will make it easier for the air inside the heat exchanger mold to flow out. The appearance of the heat delivery will be very nice.

Aluminum material will contain impurities inside. In our aluminum die casting shop, we will perform a drossing step for the melted aluminum material and will do a thorough drossing. This step can completely solve the problem of trachoma.

Diesel Heater Exhaust Pipe


Diesel heaters also produce a lot of noise when the diesel heater work, and most of this noise, is generated when diesel fuel is burned. The noise produced when the diesel air heater is working can seriously affect the rest of your customers.

To make the system as quiet as possible, good diesel heater manufacturers use quality tubing. Their stainless steel tubes have a unique, spiral thread design to soak up as much noise and vibrations as possible.

Also, pipes made from this type of steel are easier to bend, making the installation process quicker and cheaper.

Diesel Heater Exhaust Pipe Clamps

The diesel heater exhaust pipe clamps are also often overlooked, but in a diesel heater, they play a crucial role. diesel air heater exhaust pipe clamps keep everything connected and working properly.

The diesel heater is installed on moving vehicles with engines of their own, and they have their own engines too. That means a lot of vibrations and movement from different sources. Clamps absorb all that, keeping every part in the perfect position.

Exhaust Pipe Clamps

So make sure to pay close attention and follow the instruction manual carefully if you are installing the diesel air heater on your own.

The diesel air heater exhaust pipe clamp is especially important. If this one doesn’t hold in place, the exhaust pipe might start leaking toxic fumes inside the camper van cabin, which is extremely bad for health and can be life-threatening.

So don’t neglect clamps, they only seem insignificant when compared to some other more complicated parts, but they are actually vital for the whole system.

Diesel Heater Electronic Control Unit

Electronic Control Unit

The diesel heater electronic control unit is the electronic heart of diesel heaters.

The “brain” of the machine will not only allow you to use it but is also responsible for keeping everything in order, making it essential for the safe operation of the device.

Good diesel heaters have control systems that automatically check all the parts every time you turn them on, making sure everything is in perfect order.

The best mode of data transmission for the electronic control unit of the diesel heater is to use the CAN system. the CAN system data transmission, which is also the common mode of data transmission for vehicles, does not cause the data to be interfered by electromagnetic waves generated by other electrical parts of the vehicle.

This means that using the CAN system to transmit data, the diesel heater will work very stable.

The automatic altitude adjustment function of the diesel heater is one of the functions of the electronic control unit.

The automatic altitude adjustment function allows the heater to operate properly at higher elevations of 12,000 feet above sea level.

Diesel Heater Control Panel

The diesel heater control panel is the interface that controls the operation of the air heater.

It is also vital for the electronic control unit to be simple to use, and convenient. The display should be clear and easy to understand, but you also want different control options.

You can program it to start the diesel air heater at a set time, which will ensure a warm vehicle waits for you when you get up.

Diesel Heater Case

Lastly, we will mention the casing. It is what protects the components inside from mechanical damage, but it should also make the parking heater easy to install. It is important for the case to be made from durable, but heat-resistant material, such as aluminum and nylon.

Besides durability, case material matters for health reasons and should be non-toxic. The device generates heat after all, and you are likely to spend a lot of time inside the cabin. Only high-quality, durable, but safe materials should be a part of the heater you choose.

Next, let’s see what brands of diesel heaters are the most cost-effective.
