So I just moved into my new house before Christmas, and its been great. I have warmboard radiant floors and couldn't be happier with the performance. We have a Viessmann propane boiler providing heat and hot water right now, but it was always my plan to build a boiler building and install a indoor boiler piped to the house. I figured I would go this winter and realistically probably next winter with just the propane to see how much we use. But what kind of pay back makes sense for installing a wood boiler, 10 years?. I know i'm probably looking at $15,00-20,000 for a boiler, storage, piping and a building.(id be doing it all myself). I will have "free" wood from my own property but "free" is never free when you look at the work it takes plus, chain saws, splitters, fuel/oil ect. Although I do enjoy doing it and probably the biggest reason for wanting the wood boiler is that I'm about 4km down a private dirt road and then my driveway is about 1000' up a steep hill. So far I have been able to keep it in good shape for the propane truck but I never know when they are coming and conditions can change over night. And who knows where fuel prices will go.
