Up front costs of Geothermal heat pump vs. other heating methods
We are planning to build a new home near Annapolis, MD. I am just starting to investigate geothermal heat pump systems. It has been mentioned quite a few times that up front costs are more - how much more (in percentages or costs)? The house will be around 4000 sq.ft. with 2800 on first floor and 1200 on the second floor. We will have an unfinished basement that may get finished in the future (but not for quite a few years). I am just trying to get a feel for the difference between a geothermal system and a heat pump with oil backup system - there is no natural gas. We have plenty of land. Also - are there restrictions with regard to septic systems and wells?
Thanks for any input!
