Hello. I'm new to the boards. Just purchased a home that borders my land that we moved into. I've got lots of wood but the home only has s heat pump with electric backup. I intend on getting an outdoor wood boiler but had an idea I want to know is feasible. Only good place for boiler is 50 yards out of rear door. We have a walk out basement in side front corner of house with a paver retaining wall about 7ft tall. I want to know if there are any boiler designs that I could bury into the hill so the door essentially is in line with the pavers. I would then run the chimney up the gable side of the house. My air handler is in the basement and would be about a 16 ft run for the pipes. This would keep mess out of the house and be easy to fill on cold snowy days. Input/ideas? Thanks!
