I am seeking to heat 2000 gallons of water in an unpressurized tank. . I am intending to use the heat exchanger off of a 100,000BTU hydronic boiler siting on top of the riser of a rocket stove. The heat exchanger has 1.5" inlet and outlet piping. I intend to use a pump to move the water through the exchanger so there won't be any vaporizing.
A heat exchanger in the storage tank will take the heat to radiators throughout the house.
Has anyone else used a similar system? Am I missing something?
Thanks.

I am looking at doing something similar, but having the heating done with an outside tank, and lots of insulated masonry mass around and below it in a bell... water from the exterior tank pumped to a larger tank in the house, and pumped to radiators or hydronic flooring around the house.

Thanks.Hello and welcome to the community.This subject has been discussed at some length here most recently on this thread .I highly recommend reading this and following the link that references the thread by Gadget.The unpredictable nature of a rocket stove - its basically a runaway chimney fire - for my money means that an unpressurised tank inside a bell is the safest option.2000 gallons US or Imperial is a lot of water this page may give you some idea of the size of the challenge you're facing.Keep us posted with your thoughts and findings - good luck ! |

Keep in mind you can have a smaller tank inside of a bell collecting your heat, and pump it to an insulated storage tank, that way you don’t have to try to integrate your combustion device with your well insulated storage tank.
