So I own a home in Upper Michigan and it has a boiler system for heat. I want to build a rocket stove out in the yard (about 20 feet from the house) so that I can place a coil above the combustion chamber to heat water carried back to the home underground to warm 4 new radiators I am putting in the basement of the home. The idea is to use this instead of the natural gas boiler when we are there in the winter. This is our "vacation" home so I am here off and on in winter to snowmobile. I keep the home heated in the winter (about 50 degrees) but turn it up when we go up to stay there. I would much rather use a rocket stove and radiant heat when we are here instead of running the boiler constantly. Has anyone incorporated a rocket stove with radiant heat like this? I am not an engineer so I am trying to figure out what size recirc pump I need, what diameter tubing to use, etc. If anyone on here has thoughts or helpful feedback, I would greatly appreciate them!! I am very analytical and have a bio and chem degree, so this is right up my alley for experimenting. I would like to document this whole process as I fine tune the design, the set up, installation, and operation of the system which I will gladly share and post here as well as to Youtube when completed. I am new to this site, so thank you in advance to everyone/anyone reading this and for all the great posts! Daniel
