How reliable are Belief air heaters?

Dieselheat have been selling Belief air heaters since 2014 and most of them are still in operation. We have literally sold thousands with very few issues. Of course, no product is perfect, which is why we offer a full two year warranty on all Belief air heaters. We have a very short turnaround for any warranty claims (usually two days) so you can rest easy – in your nice warm caravan.
