What “Single Outlet” Means (vs. the regular multi-outlet kit)

This listing includes hardware for a single 60 mm hot-air outlet. The regular Webasto Air Top 2000 STC heater kit is often used with additional ducting and extra outlets to heat multiple areas.

  • Single outlet kit: quickest install, fewer parts, focused heat to one vent - great for compact vans and targeted heating.
  • Regular (multi-outlet capable): add more ducting/outlets to distribute heat across multiple zones - ideal for larger layouts.

Kit Includes

  • Air Top 2000 STC Gasoline Heater 12v
  • Electrical harness and connections
  • Rheostat Manual Controller
  • 22mm Stainless steel exhaust pipe (1m / 3.28 ft)
  • Combustion Intake pipe (0.5 / 1.6 ft)
  • One 60mm Air outlet with backing nut
  • Plastic fuel line (5.5 m / 18ft)
  • Fuel metering pump DP42
  • Fuel filter
  • 1 meter 60mm flexible ducting
  • Air entry and air outlet grills
  • Fuel Standpipe
  • All necessary clips and screws
  • Comprehensive installation manual

  • Works great until you use it at altitude

    This is a great heater if you use it below 5000 ft. BUT don't buy this heater if you need to use it at high altitude. I ran it for about a week until it broke from carbon buildup. I tried repairing it myself with no luck. It was also very hard to find parts for it. Took it to get serviced and they said it would cost over $700 to repair so I ended just buying a different heater. Don't make the same expensive mistake I did!

    Have only used it twice. Not cold enough in Georgia yet. But it fired right up and did the job fine.We need to get the thermostat when it goes on sale and we start to travel to colder climates or it gets colder in Georgia.So glad we were able to get the real thing.

  • Webasto Air Top 2000 STC

    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!

    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!

  • Webasto Heater

    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.

  • A week in and it's awesome!

    I'm extremely happy with my purchase of the petroleum airtop 2000. I installed it in a van which is build into a camper. I'd highly suggest purchasing the external temp sensor as well as the exhaust muffler along with this kit. So far so good!
