Good morning, Not sure if this is the correct category for this post, but I will start it here. I currently have the following setup at my house: Geothermal forced air in the house Radiant floor heat in my shop 200 gallon Heatmor OWB feeding a coil in the ductwork of the house and a plate exchanger in the shop. This setup works fairly well, even though it is undersized. My Heatmor is at least 30 years old (non Stainless Steel system). I have been thinking about what to do when it comes time to replace it. I am leaning towards not getting another wood stove. Putting up the wood each year isn't so bad, but having to plan ahead for trips to make sure someone can keep it burning is inconvenient. Does anyone make an outdoor propane boiler that I could buy to replace the wood setup? The one thing I like about my current setup is I don't have as much risk for gas leaks, explosions or CO poisoning because I am not running a gas system in either building. I could install a ceiling mount propane furnace in the shop and install a backup propane furnace in the house, but now I just added those risks back in. Not to mention I don't have the space in the house for another heating system. I see that Central Boiler has propane backup that will heat the water if you run out of wood, so there's technology out there that can do it. Just curious if anyone knows of a turn key system that I can purchase. My plan was to put up a single stall garage in the back yard where the wood stove sits now. The garage would house the boiler and much larger water storage than I have now. could also store the riding mower and a few other things in there as well. Does this system exist? Does anyone have something similar that can provide feedback about efficiency?
