Hi All!
House is going ahead , and i will be building ground source heat pump.
Question i have is this , to desuperheat or not? My idea so far is to have a seperate condenser/desuperheater before reversing valve . In heating 90% heat going to floor through main condenser and 10% to domestic hotwater. Water flow through desuperheater will be controlled with head pressure regulating valve , when it comes to summer cooling , turn off main condenser water pump and desuperheater takes over and takes all heat from a/c and puts in to domestic water. When domestic to temp , switch back on main cond pump and heat to waste and maybe desuperheater scavenging remains? Any thoughts or over sights on my part?
