Frequently Asked Questions
Q: Can I fit a Heat Air heater myself?
If you're technically minded, yes - each Heat Air kit includes a detailed step-by-step installation guide. Otherwise, a local motorhome workshop should be able to fit it for you. Whoever fits it, a qualified gas engineer has to certify any gas work to BS EN 1949-2011.
Q: Which Heat Air model should I choose?
The models differ in heat output and fuel type, with options for both campervans and panel-van conversions - broadly, the bigger the vehicle, the more output you'll want. Gas-only suits off-grid touring; if you mostly stay on sites with hook-up, the gas-and-electric version adds 3kW of electric heating.
Q: Will Heat Air work when I'm off-grid?
Yes. Every Heat Air model can run on gas, and on its low gas setting it draws very little from the battery - as little as 0.6 A.
