I currently have a ground source heat pump in my house and am looking for ways to incorporate solar heat. I prefer a large tank and low temperature. I have considered a large water tank and floor heating. Another option I have not seen suggested is to use a large tank to pre-heat water going into my heat pump. I have an open loop system that uses water at about 53 degrees. If I can heat it to 70, or even 60 degrees, it will increase the efficiency of my heat pump. It would be even more effective on closed loop systems because the ground temperature decrease as heat is removed during the winter.
