The heater is a Belief 2.2kw diesel air heater and comes with a complete 2 year warranty, with full service and parts backup. We are an Australian based business and manufacture, pack, and modify our heater kits to provide the absolute best. Our full installation heater kit contains everything you need to undertake a complete professional installation to the same standard as the European kits for approximately $600 to $800 less.
We have been importing and selling these heaters for over 5 years from the same manufacturer and have sold thousands with no major reliability issues. Heaters we sold over 5 years ago are still out there performing well.


We have other Belief diesel air heater kit options if needed.


For marine installations check out our marine exhaust kits and talk to us about kitting up a heater specifically for a marine installation.
The 2.2KW Belief diesel air heater is our recommended heater for most tiny home installations because it has a bit more power than the 2KW system, but is not as loud as the 4KW. We also sell a locally handmade wooden box cover for the 2.2, particularly for tiny home applications.

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.
