Webasto Air Top 2000 STC gasoline heater kit

Ideal for traveling or camping, the certified Webasto Air Top 2000 STC gasoline heater kit is the number 1 choice for space heating in the petrol vehicle market for a reason. This handy 12 V heater is compact in size, meaning it can be installed in a range of vehicles, and is especially suited for van conversions. The air heater’s size is so small that it can even be housed under the passenger seat for added convenience. But don’t let its small size fool you, this powerful little Webasto gasoline heater uses only 2 kW of power to provide up to 6800 BTU of heating.

Powerful it may be, but uneconomical it is not. In fact, you’ll find that this 12V heater is very fuel efficient, delivering 0.14 liter per hour to 0.27 liter per hour (0.036 gal/h to 0.07 gal/h).

And with a wide range of hot air ducting accessories available for this air heater, you can even transform it into a Webasto bunk heater. When it comes to temperature control, this air heater comes equipped with an integrated temperature sensor that will ensure that the heat stays at the level you have set. And if it’s enhanced heating control that you are looking for, you can purchase an external heating controller.

Produced and put together in the EU, this air heater comes from one of the globe’s most reputable brands that is based in Germany. So, you’ll have peace of mind, and not only that, with repair shops and spare parts available globally, you’ll not need to worry about maintenance.

    Webasto Air Top 2000 STC

    Posted by Zach F on 12th Sep 2021

    Heater works very well. No regrets from this purchase. Installation was a little rough with no directions. Had to try and piece it together from youtube videos of others doing it.

    Works amazingly!

    Posted by Troy on 13th Apr 2021

    With all the youtube videos available the install was extremely easy!

    What would be an amazing option is a auxiliary fuel option, like the RAM Promaster, so we can buy the parts from Heatso instead of the hardware store.

    Besides that from shopping, to purchasing, to receiving, to install it all worked great!

    Works well. Was a relatively easy install (directions aren't good there are some pretty good guides on youtube and the web). Arrived quickly and works as advertised.
