A reliable diesel air heater can be a game-changer for Aussie travellers and tradies. The Thermomate 12V 5kW model delivers instant warmth wherever you park up, without complexity. Its all-in-one design neatly houses combustion, intake and temperature controls — so set-up is refreshingly straightforward, and ongoing use is as easy as toggling modes on your LCD panel or remote.
This unit is purpose-built for small living spaces: caravans, campers, vans, and work trailers. No separate under-vehicle install, no high-pressured gas lines — just connect to your existing 12V supply, top up diesel, and enjoy consistent heat. Whether your adventures take you north for winter sun or south for snow camping, this is warmth you can count on, night after night.
Better yet, being diesel-fuelled keeps ongoing costs practical and maintenance minimal, unlike some other mobile heating types available in Australia.

Australian Installation Tips
Most handy owners can self-fit, but if you’re unsure or your installation will pass through firewalls/metalwork, it’s wise to call in a professional. If you DIY, set aside half a day, use high-quality cable protection, and always verify your wiring aligns with the official diagrams. Ensure a safe path for air intake/exhaust and keep fuel lines shielded from heat sources.
- Mount in a spot where airflow isn’t blocked by gear or bedding
- Position the diesel tank outside living areas for safety
- Fuse your main power for added circuit protection
- Double-check duct outlets won’t direct warm air at sensitive or plastic trim
