I'm looking to build a new house in the Boston area. I have land of 11000SF. No foundation yet, so i have all the flexibility a this point to do a closed ground loop GSHP. I don't have access to Gas and I'm trying to avoid have an underground propane tank. I'm also looking to use solar shingles (DOW Powerhouse) to help offset the electricity bill. The lot is not level and the basement will be a walkout basement. I'm planning on radiant heat in the basement foundation (and driveway) and then forced air in the 2 floors above. The house will be around 2800SF without basement. Front door facing west.
I have several questions here that I would appreciate your help:
- can I do the loop under the foundation?
- will the system generate enough hot water or do I need an electrical water heater?
- I'm not sure i understand the difference between the water holding tank or the Desuperheater (DSH I think)
- I would like to use some of the heated water to melt the driveways, how?
The idea is to have one system that works and uses electricity as the main source of fuel.
I have not spoken to contractors yet, however, I have been able to learn a lot by reading on this forum (thank you for the great info) among other sources on the internet. I'm trying to gather additional feedback before talking to dealers so that I know what i'm in for and ask more intelligent questions.
Thanks in advance.
