I'm getting ready to convert a 2021 Promaster 159 this Spring and have been researching for a heater. I like the fact that the Espar has an automatic alltitude adjustment but have read that there have been problems with the unit. Would love to hear from the community as to what you all recommend. I also read that Heatso is not a licensed dealer for Espar? Does anyone know of that is true?, and if so were is the best place to buy one? How are customer support for either of these manufacturers? Any and all help is greatly appreciated.

Espar B4 user with altitude kit. It just works. Even for hours on low at 9900'.

Honestly it pumps out too much heat on low in our Extended. It has to be aroud the mid 20s outside before low doesn't cook us out of the van and it cycles on and off. I need to play with bringing in more ventilation to offset the heat so it doesn't cycle off and on.

As it gets colder it just stays on low and it's comfortable into the low teens F.

I installed the gas webasto gas a year ago. I have not used it a lot, sometimes at altitude and only when it is below 50 outside (actually mostly when in the 20's F) so far, no problem, but I probably only have 50-100 hours of use total. It came from Heatedupamerica via Amazon (they seem defunct) The supplied unit was clearly made in Russia and when I called the vendor for support (the supplied harness didn't support the Rheostat) they immediately shipped me a replacement that was "universal" in that both the digital and rheostat work.

Connecting it to the aux port of the fuel tank was pretty easy aside from multiple trips to NAPA to get the right size hoses. I purchased a rheostat to apply the altitude adjustment detailed in FarOutRide. I never did the adjustment and I only use the Rheostat and, so far, I only use the lowest setting even when ~20f outside. When super cold the burner comes on maybe 30-50% of the time and the cabin stays mid to high 60's which is fine for snuggling in bed. Per the spec a night of heat (12h) should only burn .9g (less than .5g at 50% duty cycle) and indeed, heating for a couple of nights made no appreciable difference in the fuel level.

I can't imagine why you would smell either gas or Diesel as all that should be external to the cabin. If exhaust is being sucked into the cabin then something SERIOUS is wrong. Fix it.

The only reason I picked gas was to avoid a second fuel source. My goal was an all-electric van. I certainly wasn't going to have Diesel anywhere inside the cabin and I was nervous about having fuel under the hood (a safety hazard in a collision) and I didn't consider putting the tank under the van and use the DEF port for a filler (a friend is doing that, what a pain).

OTOH Having the alternate fuel source can't drain your main fuel tank. If I were to build a second van, or replace my current heater, I might reconsider a cheap clone and 20l aux fuel tank somewhere under the van.

I mounted my heater behind the drivers seat over the void just behind the filler tube for the main tank. That way I used the filler guard to shield the fuel and electrical lines going to the pump. It is buried in my raised floor behind the swivel seats.

I think maybe what I said is being misconstrued. I have a heater, properly installed, no exhaust comes into the cabin.
The scenario that I have run into is this:
1. Heater is on and cranking I am nice and toasty in the van.
2. I am about to cook some dinner so I open the window above the sink which is maybe 6' total from the exhaust pipe that comes out by the drivers side near the wheel well.
3. I turn my ceiling fan on to suck air in from the outside.
4. Exhaust from the heater, gets pulled in through the open window.
5. I reverse the fan, problem solved, air gets pushed out of the window near the exhaust instead of pulling the air from that window.

I am not sure how that could/would ever be avoided with the current position of the heater's exhaust pipe. My plan in the long term is route the exhaust out the back of the van instead of the side like most installs. Shorter runs are less complicated and less work to install which is why most people run their heater exhaust right out the side instead of piping it to the rear.

Planar diesel heaters, top notch product from Russia. And half the price as Wabasto or Espar! I bought the Chinese version, absolute junk! Sent it back. Planar arrived quick even thou coming from UK. I ran a bench test and works like a champ. Gonna run two gallon tank outside in rear. Nothing like these barking/parking heaters. Many applications, cabin, boat, rv,rig. Good luck. 👌🏻👀🤙🏼
