Product Q&A

Ask Us a Question
  • How does the size of the area to be heated affect which diesel heater to purchase?

    A larger area might require a twin outlet or a more powerful heater.

    • A 2kW diesel heater will be sufficient for a vehicle around 4-6 metres
    • If the layout affect the heat flow or the area is a bit larger, a twin outlet is recommended
    • With a large motorhome or fifth wheeler, it is best to opt for a 4kW diesel heater
  • what is the noise rating in Dbc

    Hi There,

    The manufacturer of this heater does not provide a noise rating sorry.

  • Should I buy a gas or diesel heater?

    It depends on your personal requirements. Please see the pros and cons of both below:


    • Pros
      • Most caravans already have gas appliances so adding a gas heater is relatively straightforward
      • Purchase cost is lower than a diesel heater
      • Noise is lower than diesel heater
    • Cons
      • A number of regulatory requirements apply for installation: a gas heater flue cannot be installed too close  a window, door or other gas appliance inlet or outlet, or under an enclosed annex A licensed gas fitter is required to connect the gas heater and provide a compliance certificate
      • In temperatures of two degrees and under, the heater won’t function
      • Produces a wet heat resulting in unwanted humidity and condensation


    • Pros
      • You don’t need a licence for installation
      • Superior heating performance compared to a gas heater
      • Produces a clean dry heat as opposed to the wet heat produced by a gas heater
    • Cons
      • More expensive to buy than a gas heater
      • Generally noisier than a gas heater
      • You need a clear space below the heater for the exhaust
      • Extra diesel tank needed
  • Does the diesel heater come with a fuel tank?

    No, a fuel tank is not included with the purchase of a diesel heater. You will need to add a fuel tank to your order. However, if the vehicle runs on diesel, you will be able to plumb into the vehicle's fuel tank.

  • Can I use biodiesel or kerosene to fuel the diesel heater?

    No, it is recommended that you only use high grade diesel, and not biodiesel or kerosene.

  • What is the advantage of a twin outlet over single outlet?

    The only difference between the two is having two outlets into the van instead of one. If you choose the twin outlet model, you’re able to direct one outlet one way and the other outlet another way. However, the performance on the two models is the same.

  • Can I install my diesel heater under the bed?

    Yes, you can. Just note that there will be some noise due to the intake of the heater as well as a ticking sound from the fuel pump. Therefore, it is probably best to install the heater away from the bedroom.

  • What is the difference between the rotary and digital controllers for diesel heaters?
    • Rotary controllers do not have a thermostat and consist of a dial that is based on feel and you will need to turn it up or down until you are satisfied with the temperature. The heat will remain constant once set to a specific dial position.
    • Digital controllers have a thermostat and you are able to digitally select a temperature. These controllers also have a timer that can be set if you only want to run the heater for a certain amount of time.
      • It is recommended the digital controller be installed at waist height as a result of heat rising. It will reach its temperature too soon if installed too high or will have to work too hard if the thermostat is too low.
