Our portable diesel heater is a full 2.2kw Belief heater enclosed in a portable rust proof aluminium box. You can now take your heater from a workshop to a caravan to a tent. Designed to withstand light rain and plenty of bumps, this portable is ideal to heat a tent, annex or to duct into a camper where installing a heater full time isn’t possible. The 2.2kw heater will provide ample heating for most applications. With all components included in the kit, you will be ready to go.

  • 2.2kw Belief diesel heater
  • 12v Anderson plug

All air heaters sold by Dieselheat carry 24 MONTHS warranty from date of purchase. Warranty is return to base which means you are responsible for returning any defective heaters to us for repair.

If you have an issue every attempt will be made to fix it via phone or email. Warranty is on heaters only and does not cover any issues caused by installations performed by the customer or other parties. If we can’t fix any issues with heater operation over the phone or email then the unit and possibly other parts as we suggest to you depending on the issue must be returned to us using an Australia Post air bag at your expense.

On arrival at our premises we will set the unit up on our test bench to ascertain what problem has occurred. Any defects or issues with the heater will be fixed free of charge and the unit will be shipped back to you at our expense. If the unit operates without any problems it will be deemed an installation problem and this is not covered by warranty. Any costs involved in returning the unit to the customer is at your expense.

Please note all diesel air heaters need to be run at a high power setting for around 15 min every 4 to 5 hours to prevent carbon build up. If this is not done and the heater fails due to carbon build up this is not covered by warranty and any repairs needed will be charged.

Please do not try to disassemble the heater yourself whilst it is still under warranty without consulting with Dieselheat.
