Reliable and HOT!

After burning through two Webasto burner inserts within 2 months, operating at 8500ft (yes they were adjusted for altitude) I decided it was time to try something else. Glad I found the Planar and expedition upfitter! I've had 2 years of reliable service with the Planar, mostly in CO, and much of it above 6k ft!

We've installed 3

We just purchased our 3rd Planar heater and installed this in our Arctic Fox. We love them, we now have one in our boat and camper (we sold the van). Can't wait until Total Composites releases a larger truck camper, then we will outfit that!

Best mod yet!

Even without fully insulating the Sprinter yet this has made a huge difference in winter comfort level. Our Sprinter is a (slow) work in progress and this made our month long trip over December so much more bearable.

Now just waiting for the new digital thermostat.

Planar 2d

Very impressed with the quality of the components in the kit. Good installation operating manual, easy installation with all required parts included (less the fuel tank).
Painless initial startup, no smoke or odour. Have not used at elevation yet, but have no doubt that it will perform as advertised. Solid warranty, and great that spare parts are readily available locally.
Highly recommend this heater.

Planar 2d

I opted to install a Planar 2D diesel heater, high altitude version, a few months ago and just returned from an extended trip including 3 weeks roaming around Colorado. I'm extremely happy with the performance so far. One night was above Leadville (10,000+ ft) and the heater fired right up (as always) and worked flawlessly. I have the basic PU-5 controller which adjusts output manually.
