I am trying to decide on air source vs water source heat pump for residential hvac north of Boston MA.
Ground loop is not a possibility pump & dump not a possibility. SCW with bleed is a possibility.
GWHP sounds great but I cant get a handle on the well pump losses.
I have heard that the well pump bill can approach the heat pump kwh usage.
So much for high COP numbers. any comments on that?
Also how long will a well pump last under heat pump type loads?
Heat load calc is coming, currently whole house is adequately heated with .85 gpm oil burner. around 100kbtu/h.
Install even though i have the well already is $$$$ for geo, less for air.
not sure i can recoup the difference. any comments?
