Geothermal System for Heating and DHW
Hello, I’ve just purchased a home in Northern NH and would like to get off of propane if possible. The home is using an older Series DE boiler (PeerlessBoilers) from 2005 to heat the DHW and hydronic baseboard. From what I can tell, the hydronic system was also installed in 2005. All rooms have hydronic baseboard and the pipes appear to be in good condition. There are two LP tanks outside used to fuel the boiler. My question to the group is if I can replace this old propane-fueled boiler with a new geothermal heating system: Can a new geothermal heating system create enough hot water for both DHW and hydronic baseboards (forced hot water heating system)? If so, what make/model do you recommend? Note that I don’t have any ductwork and am not looking to use geothermal for AC/cooling, just the ability to heat the DHW and hydronic. The house is 4-bed/3-bth and ~3800 sf, and I believe we have enough land to install either a horizontal field or vertical field for the geothermal. We are pretty far north (parallel to Northern Michigan and Wisconsin) and I’m not sure if there are geothermal systems powerful enough to heat water up to the 87+ MBH needed for both of our homes systems. Thanks for your help.
