How does a diesel heater work in a campervan?

Burning diesel fuel heats a heat exchanger in a camper van diesel heater. Fresh air is drawn in during the combustion process, and combustion gasses are released through an exhaust. As the diesel fuel burns, heat is transferred to the huge surface area heat exchanger. After that, a fan brings in the hot air from the heat exchanger. The campervan’s living area is then filled with heated air, which makes it cozy and toasty.

Diesel heaters for campers can be linked to either an additional fuel tank or the vehicle’s fuel tank. As a result, even with the engine off, the diesel heater may be used. Additionally, the majority of diesel heaters have safety measures like an automatic shut-off that activates in the event of an overheated heater or a fuel supply issue. A thermostat or remote control may also be included with certain models, enabling you to operate the heater and change the temperature from a distance.

Types of Campervan Diesel Heater

Diesel heaters for camper vans come in three varieties:

  1. Air heaters
  2. Air and water heater

This implies that you receive “free” hot baths or heat for a considerable amount of time following a journey!

For the majority of vehicles, a 2kW diesel heater should be plenty. In the event that you want to utilize your huge van in really cold weather, a 5kW diesel heater would be a better option. A heater should be sized for approximately one kilowatt (KW) per 14 cubic meters of living area in a home with adequate insulation. We should double or quadruple this number in a campervan.

  • Generally speaking, a lot more pleasant temperature in vehicles than the intense, quick heat of the 5kW

5kW Diesel Heater

  • Because of its power, it usually just needs to operate on low.
  • Compared to the 2kW version, you will operate it on low more often, which means you will need to burn off the extra carbon buildup more regularly (i.e., run the heater on high).
  • Possess the choice to turn it up further in really cold weather.

Diesel heater safety and regulations

  • The following are some things to be mindful of:
  • The campervan has to have a heater fitted inside.
  • When the car is moving, the heating cannot be utilized.
  • The van’s intake and exhaust must be routed outside of it.
  • The exhaust ought to be directed away from any windows or the air intake so that it cannot be drawn back in.
  • The van’s edge is where the exhaust must exit. Carbon monoxide can build up below the van and become drawn back into the air intake if it isn’t vented away from the edge.
  • The exhaust pipe should be angled downward to avoid internal condensation buildup.


Although you may heat your camper or motorhome with a variety of fuel sources, diesel heaters are usually regarded as the finest heaters for van living.
