This product comes in 5kW and 8kW versions, but the 5kW should be suitable for most small to large camper vans.

8. Webasto Air Top 2000 STC Diesel Heater Kit

Having deja vu? We’ve covered this product earlier on this list, but it was worth noting that there is an Air Top 2000 STC kit available on Amazon that offers a number of bells and whistles that the base product doesn’t.

The Webasto Air Top 2000 STC Diesel Heater kit is a pricier, but definitely popular, option to consider for your camper van.

This product is known for being particularly powerful and able to heat extra large camper vans and full cabins alike.

There have been quite a few recurring brand names on this list, but what about the off-brand diesel heaters one can find on Amazon and eBay pretty easily?

These are hit or miss (big time) but they come at an extremely low price point.

On one hand, you might be out of $50 because the cheap product you bought was a dud. On the other hand, if you’re camping on a budget, you might be pleasantly surprised to find that your $50 product works beautifully all through the night.

Final thoughts on diesel heaters for vans

That’s quite a long list of diesel heaters, so let’s break down some of the things you might want to consider before purchasing a diesel heater for your van:

  • Price: Prices range a bunch. The Vevor costs around $145 while the Webasto costs over $1.000 – but might last you longer.
  • Durability: An imported diesel heater likely won’t last as long as a german made Webasto diesel heater.
  • Availability: Most diesel heaters sell out rather quickly.

I wish you the best of luck finding a diesel heater for your van.
