what size of forced air heater would be good for a 22' enclosed... iwas thinking 30-35000 btu.....Also which brand seems to work and cheapest place to get them?
Thats plenty big for that cubic footage. Your ducting will really make the difference.
Ebay is a great place to find them.
Locally here we have newspaper that has a free classifieds site online and it is amazing what you can find on there. I have seen piles of RV furnances for cheap.
Don't know what you have up there tho.
ebay is about the cheapest place. I just bought my 42000 suburban heater off adventurerv.net i believe for 660 bucks. Get biggest heater you can. better over kill then not having enough.
