Hello and great site here.
I own a 4 bed room 2 story home....roughly 2500 sqft. We use oil burner hot water baseboard now and want to begin our "green" journey. I am very interested in the geothermal water to water sytem. We are on a well for water. the house is 5yrs old.
I live in NH.
To convert to this type of system....what will my cost be?? Is this a 10-20k fix or more? I plan to contact a couple of installers however I wanted some idea prior to getting quotes.
I know you guys can't tell me exactly...just rough ball park $$$$$.
Thanks again to all, and I am open to any and all advice.
Greg

For baseboard, you'll not get enough temperature out of a geothermal system to completely heat the house. The max. temp. you'll be seeing will generally be 120 deg. F.
With 120 deg. water, you can heat a house with baseboard heat, down to a certain outside temp. At that point, the heat loss of the house is too great for the 120 deg. water to keep up. This would be called a balance point temperature. At balance point, you'd need something else to heat the water to a higher temp (oil, gas, elec,), or switch over to forced air.
If your goal is to realize the savings, comfort, and "green" of a geothermal heat pump, you probably need to have a forced air system retro-fitted to the house. For that, the cost will be pretty high. I don't know your particular area, but in my area, that price would be $25-$35K. This would then abandon the baseboard heat and boiler.
Hope this helps.

| you can often size baseboard to run at 120 under design conditions. it might require some rehab of the existing baseboard system to make that work though. Maybe spot replacement of units with radiators as well. certainly nothing in that kind of a price range would be required unless demolition requirements were large. |

That's right. It would basically take more radiator (more heat exchanger area).
