ello. I'm new to the forum. I search and read the forum all the time but my first time posting. I'm looking for help with heating 2 greenhouses. One is 1200sq ft and the other is 432sqft. I live in northern California below the snow line. I am trying to keep to a budget so I am looking to put an indoor forced air furnace in the large one and some sort of wood stove in the small one or maybe a pellet stove. I know allot off people use outdoor wood boilers but they are a little expensive. I would like one one day. I am thinking about the Englander furnace or daka for the big one. These are around 1200$. For the small one, I am not really sure. It's a small space and it is covered with double layer poly. I'm worried it will get to hot in there and then it will be freezing come morning. Things to add: the small one I am going to re-cover with double layer poly and will be used only in the winter. The big one will be used march - November. I wanted to know what you guys thought about the cheap wood furnaces and which ones have the biggest firebox for the money. Also some ideas for the small greenhouse. Something to mention is that live off grid. I have a decent solar system with backup generator but power is conserved whenever possible. I live on 20 acres of oak and madrone and wood here is easy to come by.
