Does anyone know of a heat pump that can handle 120ºF input temps? I would like to use one to retrieve heat from my solar storage to boost to 140º from 40 to 120 for dhw and fancoil use. Any recommendations would be appreciated. Bob

Bob, Before going down that road why are you using fan coils @140F for space heating when baseboard or tubing in the floor would be more efficient . 100-110F would then be the target temperature of your solar storage. Adding a heat pump will become expensive and the ROI will be many years. Back to your question , Robur Model GAHP W LB can supply hot water up to 140F and chilled water to 23F.

acwizard - the fan coil heats my incoming fresh air and runs on glycol. The fresh air comes in through an earth tube which is working better than expected so I may not need as much heat as first thought.
