Small RV furnace for cab heat.........

[FredH]

It sounds like you pretty much have it figured out and Kudo's :thumbsup: to You for sharing .

This sentence though early in the thread almost made me fall out of My chair laughing :

" lack of any real effective place to mount them without one body part or another spontaneously combusting. " :laughing:

Being a trucker , I knew about the wabasto and espar heater's . Small , Effective , But not cheap by any means , thus I could see you going a differnet direction .

Good job . :thumbsup:

I would never do the lp heater, we used to do that on some trucks, the instructions said not to be in it lp running, about 2 weeks later we went to gordys funeral.

Nice setup. Clearing snow is fun unless you're freezing your nuts off and then you start to hate snow.

LP or any gas driven heater can be safe or dangerous. This setup was done very intelligently from the getgo. The use of outside air and not recirculating air will almost negate the need for a CO alarm, but it isn't a bad idea. ANY furnace in your home can be deadly. Elec can start fires, and nat or LP furnaces can and will kill you with CO if there is a defective heat exchanger.

For the OP, the only concern I had when reading this (first read today) was it being oversized, but with you using outside air and not recirculating that reduces the Delt T mentioned earlier in the thread.

Nice work, and glad to see you stuck to your original idea. Using any type of engine heat exchanger setup would have required a lot longer warm up time before you got heat.

This project has me thinking of a cab for my riding mower, not for heat, but mainly for dust and pollen (shade wouldn't hurt either). My rider is big (Husqy GT52 with fabricated deck) it is not as big as your Steiner, so it would be a little trickier to design. Great work, look forward to your other ideas.
