Experience quiet, powerful heating for your camper van. The Planar 8DM Air Heater (Diesel, 21,000 BTU) is a compact, fuel-efficient, diesel-powered air heater that will keep you warm and dry on even the coldest nights.

The Planar 8DM Air Heater gives you reliable heat up to altitudes of 5200 feet (1600 meters). 

This complete Planar 8DM air heater kit contains every component you need for a camper van/motorhome installation, including the heater, exhaust and intake tubing, fuel tap, etc. The 8DM even comes with a 7-liter fuel tank, so you can either use the provided fuel tank or just tap into your main fuel tank if you are installing this on a vehicle with a diesel engine.

Use the drop-down to select which voltage you want:

  • 12-volt DC
  • 24-volt DC

Not sure which model to get? Use a BTU calculator to calculate the interior dimensions of your space, your insulation level (because it's a van with windows and not much thermal mass, I'd select "poor"), and desired temperature increase - calculate the maximum heat output you might ever need, and size your heater to be capable of that.

Note: This diesel-powered air heater can operate from low to high temperatures. However, like any diesel heater, you should periodically ensure you are running the heater at the highest temperature (every 12 hours of run-time, approximately) to burn off the soot created by low-temperature use. If you do not do this, you will get thick white exhaust smoke from the soot buildup inside the combustion chamber.

Returns not eligible 14 days after delivery date. 

Key Features: Planar 8DM Air Heater (Diesel, 21,000 BTU)

The Planar 8DM Air Heater installation kit has everything you need for a heater: 

  • Compatible with the Mercedes Sprinter.
  • Heats up to 35-48 ft. boats and commercial trucks, suitable for heating a large space.
  • Comes with the PU-27 digital programmable controller
  • Planar installation manual is included
  • Available in two voltages, either 12V or 24V 
  • So light at 26.45 pounds
  • Two-year warranty.

Note: If you are installing this heater on a 2007+ Mercedes Sprinter, you may have the KL1 auxiliary fuel tap installed on the top front of your fuel tank. If so, the fuel line is typically a 5/16" nylon line which can connect to the Planar heater with an adapter like the Dorman 800-188 fuel line adapter. If you do not have a fuel tap already installed on your fuel tank, you may need to drop the fuel tank to install the fuel tap.
