A diesel heater is a heating system designed to provide instant heat to the interior of vehicles, boats, sheds and other enclosed spaces. It works by drawing in air from an external intake pipe, which is then mixed with diesel fuel and ignited in the combustion chamber. This process heats up a large surface area of a heat exchanger.

An internal blower then draws cool air from the cabin and passes it through the heat exchanger, where it is heated and then blown back into the cabin. 

The combustion exhaust air is kept completely separate from the cabin air, and is vented outside through an exhaust pipe. This is an important safety feature that helps to prevent carbon monoxide poisoning, ensuring the safety of the occupants.

The diesel heater provides instant heat and can be easily controlled to regulate the desired temperature inside the cabin. With its low fuel consumption and cost-effective solution, it is a popular choice among those who travel in cold conditions.

In summary, the diesel heater uses diesel fuel to heat up the air, using an heat exchanger and an internal blower to circulate the warm air inside the cabin , while the combustion exhaust air is kept separate and vented outside. This will provide instant heat to the interior of your car, van, truck, motor-home, sailboat, powerboat or yacht.


Here are three reasons we recommend you choose a diesel heater as your heating solution for your next adventure: 


Diesel heaters are designed with safety in mind, and you can trust that they are safe for use.

One of the key safety features of our diesel heaters is their automatic shut-off system. If the temperature ever exceeds the design specifications, the heater will automatically shut down, preventing any damage from overheating.

Additionally, there is no risk of combustion or inhalation while using our diesel heaters. The combustion chamber is completely sealed, and all exhaust is vented outside, ensuring that there is no risk of carbon monoxide poisoning. Whether you're on the road or spending the night on your vessel, our diesel heaters are safe to use while operating or sleeping.

Please note that safety instructions must always be followed during the installation and operation of our diesel heaters. It's important to read the user manual carefully to ensure that you understand how to use and maintain the heater safely and correctly.


When it comes to heating your vehicle or vessel, especially in freezing conditions, diesel heaters offer superior performance. With low fuel and power consumption, they are a cost-effective solution for keeping warm.

Other heating options may use fuels that don't burn well in cold temperatures, resulting in "wet heat" that can cause unwanted humidity and condensation. But with diesel heaters, you'll experience a clean, dry heat that is not only more comfortable, but also more efficient. Whether you're on a long trip or just camping overnight, a diesel heater is a reliable and effective way to keep warm and comfortable.


When it comes to heating your vehicle, diesel heaters provide precise temperature control, allowing you to easily maintain your desired level of warmth. Once the desired temperature is reached, the heating unit will automatically operate at its lowest settings to maintain the desired level of warmth. Additionally, when properly installed, diesel heaters operate very quietly, so you can enjoy your travels without any disturbance.

While diesel heaters may be a significant investment, the convenience, comfort, and safety they provide makes the investment worthwhile. We are known for our quality products, offering a 2-year warranty, and we also stock all spare parts in Australia, providing you with peace of mind. With our diesel heaters, you'll be able to enjoy your travels in comfort, no matter the weather.


When helping you choose your new heater they will probably ask you the below questions. The answers to these questions will help you determine your need for a more or less powerful heater (2KW or 5KW).

  • Do you intend to spend a lot of time in cold locations? If you plan to stay in snowy locations, a more powerful heater is recommended.
  • What is the size of your vehicle? If your rv or caravan is closer to bus-size, a 5KW heater will heat up your space quicker
  • Does your caravan have many large windows? a lot of energy is lost through window glass. The more windows you have the larger the heat loss.

So, order yours today here - Diesel Heater.

After all, you deserve to travel in comfort regardless of the weather conditions.

Hi Ian, our heaters use diesel as fuel and a heating element (glow plug) to start-up. It uses minimal power (12V) for the pump and LCD controller. It does not require gas. However, you may have a different model?

My heather does not work lately the control panel does not work to get heating work

The question that I would like answered is, as the fuel is injected into the unit, what burns off the fuel as it passes over the heating chamber? Is the chamber heated by Gas or a 12v heating element?
The reason I ask this question is, on a resent trip in our Motorhome, we were using the heater at night before bed and in the morning to warm the living area. However, it appeared that I used more gas than usual.
