Key Tips When Installing a Diesel Heater

It’s been 3 years now of installing diesel heaters and probably around 250 heaters installed in different vans. What are the most important things I have learnt after that time?

1. That first hole is critical. Take your time to ensure your heater is located in the right place and then drill the 100m / 105mm hole.
2. The smaller the van the trickier the install. Generally hybrid vans are the most difficult as they have very limited options for locating the heater. That said we haven’t come across a caravan yet that we couldn’t install a heater in.
3. 2kw is enough for virtually all vans. Unless you have a big motorhome or a very large van, a 2kw heater will do the job adequately.
4. Newer caravans are coming with sealed batteries so you will probably need to tap into an existing circuit to power the heater.
5. 1 outlet vent is enough. Your van will get warm very quickly.
6. Smaller motorhomes are generally the trickiest to work on because they sit so low to the ground. I have the scratches to prove it.
7. Wherever possible diesel tanks should be located outside the van. It’s only happened once that someone got the smell of diesel in the motorhome – but now I am careful to insist on tapping into the main tank or running a temporary tank until you can.
8. The most expensive isn’t always the best. I highly recommend Au Focus heaters as top value for money. I also know the business owners bend over backwards to help any clients with warranty issues. While the European heaters may be a better product the limited after sales service options and cost of spare parts make them less desirable in my opinion.
