Those things have been around for ages. They are typically intended for remodeling jobs, additions, enclosed porches, and etc. They are meant for sticks-n-bricks homes. They are available in either natural gas or LPG.

I know I saw a thread on one of these made for RVs so it didn't need a 4" wall. Seems like a great idea to supplement the furnace.

Found it; it is called the Platinum Cat and comes in two sizes. A member named Sleepy installed in his truck camper and has a thread on it.
And, okay, I see it was mentioned at the top of the page. Shouldn't be hard to get as they sell direct to the public. Oops, 8 week delay. Arnie will build custom units as well if the regular model doesn't have connections in the right spot for your application.

Maybe mount on in a cabinet door, under the kitchen sink?

What? I don't think you want this venting in your kitchen cabinet.
Edit: I did see one that way with flex vent hose running through the exterior wall.

Those sq. ft. estimations for heating are about standard residential heating requirements. My 22' trailer has about 140 sq. ft. of floor but a lot of that is taken up by fixtures, of course. The 20K btu heater I use is operated on "low" or "pilot" most of the time. I think that 8K btu unit would heat a standard trailer or class C pretty well.

That depends to a large extent on how cold it is outside. If you are camping in cool or only moderately cold conditions, not too much below freezing, it would probably be sufficient.

A typical RV furnace is what, around 20,000 or 30,000 BTU. If it can operate with a perhaps a 15% duty cycle and maintain a comfortable temperature, this should be adequate. (Another comparison is with a 1500W electric heater, which is around 5000 BTU. This would be equivalent to one and a half typical electric space heaters.)

One decided advantage of the larger furnace is that it can heat up a cold RV much more quickly. This would take a pretty long time to get a cold RV up to room temperature, even if it can maintain that temperature fairly well.

There are two sizes larger than this. The tanks, can't help you there.

I don't see the advantage of this. It is only good for 200sq ft and that is probably assuming 4" walls with corresponding insulation so I'd guess 100 sf ft in a 2" walled camper. And it will not put any heat in my tank area like my furnace will.

Oh if I had the option of going electric I sure would. This looks great for the boonies and those that can't take the noise of the blower on a regular RV furnace.

In my case there is a spot in the bedroom that would work. Happily it is just above the exterior barbecue grill connection. I still don't know if I want to burn propane vs running on electricity for space heating.

Hi Jim,

What you saw was Sleepy's Platinum Cat vented catalytic heater. It works well, but is a hard to get item (read nearly impossible).

I've seen the wave heaters mounted on a door with flexible exhaust tubes. Couldn't that be done with this?
