If you go with the Propex heater they have a version that you can mount outside.
Works great for us and no lost interior space.

Where did you mount this (pictures?), and how are the ducts run to the interior? It was on my short list initially but I opted for the HS2000 instead. If I do another build I might favour the external version.

 

Mine is mounted in the rear, roughly 3' from the back and 1' from the driver's side. The floor ribs had a huge influence on my decision, and there's a place where it's nice and flat there. Another exists a few feet behind the driver's seat, which is where I have a floor vent.

The furnace lives in the bottom of a cabinet that would have otherwise not been that useful due to the wheel well being right there. The heat duct vent is mounted nearby.

 

No troubles with crap getting kicked up against the intake / exhaust?

 

I mounted this unit within the interior forward of the driver wheel-well; HS-2211.
below shows the output vents, keeps the feet warm😁 Combustion air and exhaust are both exterior of the vehicle.

 

Any reason you chose the exterior version instead the interior one to use inside the van? Availability?

 

This interior version has the combustion intake and exhaust on bottom of the unit shown above. The mounting location did not have space to accommodate this unit to duct intake and exhaust directly through the floor.

Interesting discovery: The Propex thermostat received with my unit will not turn on the heater on a warm day. After some LPG system work, I wanted to purge out any air, had to wait for cooler temps. So what's the point: I you are gonna want to have a Transit-Propex-sweat lodge, ya gotta get a different thermostat🤣

 

Nice. Never noticed that difference when looking at them. So do you have it mounted with the flange to the floor (i.e upside down) or did you mount it flange up so it is in the same orientation as if it was mounted under the van?

 

Here is a good video on installing the HS2000 under the passenger seat -

 

Put our propex behind the drivers wheel well. Working fine for us.

 

same as sparky here. Driver side back by the rear door nice flat spot. makes under the bed nice and cozy

 

I put mine in front of the passenger side rear wheel. The van floor is flat there so the install is pretty easy and it isn't in the way.

The combustion air exhaust exits in front of the rear wheel and angles towards the back. No problems with exhaust coming in when the slider is open so far.

The rear wall of the kitchen counter straddles the heater.

The hot air is directed out through the garage into the living space. You can't see it in the picture but there is an adjustable splitter that supplies warm air to the garage.

I used a flat louver on the hot air exhaust rather than the angled one you see on most installations. The angled one heated too much of the floor or directed the hot air straight up. A curtain between the front seats and the living space helps a lot with this arrangement.

I made sure to put the thermostat up at bed height. This arrangement works well for us and I don't have to remove the seat to maintain the heater.

P.S. I would have put it on the driver side if I had thought about installing it earlier in my build.

 

I’ve used that exact same location.

What are you using for the exhaust hose? The hose that came with mine was too long to mount the muffler there, and when I tried to cut it down I couldn’t fit the cut end over the muffler flange due to the ribbing.
