How to Choose the Right Diesel Heater

  • 2KW Fixed Unit = Great for leaving on overnight or small vans (up to 19-20ft).
  • 5KW Adjustable Units = Perfect for quick heat-ups in the morning or before bed in larger caravans or motorhomes.
  • Portable All-In-One Units = Ideal if you’re in a tent, camper trailer, or rooftop tent, and don’t want to permanently install anything.

Diesel Heater Tips (Run ‘Em Right!)

  • Always run your heater on high for 10-15 minutes after long periods on low to prevent carbon build-up.
  • It’s better to have a smaller unit working hard than a big one running low all the time.
  • Keep your fuel clean and your filter clear, and you’ll get years out of your heater.
