Heatpump for solar hot water
Launboy Good job with the solar. Did you know there are polycarbinate sheets for roofing avalible to cover your solar hot water collectors. The home Depot and other suppliers carry them. They are clear corrigated roofing sheets treated for ultra violet exposiure and quiet reasonably priced. Just to cover them to prevent the wind and exposure from removing heat would improve their efficency.
Launboy wrote The solar has appeal in your application too! You said it works really well when it's sunny and provides hot enough water on its own, but on the days where the water isn't hot enough to use directly you could run it through the heatpump.
The short answer yes but no. Don.t forget if there is no heat the heat pump is not going to help. You will only gather the small amount of heat that is there and start to freeze the panel. Remember the solar hot water panel is insulated all around and if there is no sun there is no heat and you will form frost on the interior of the panel.
On the days with no sun the Geothermal heat pump starts and warms the concrete floor from the huge source 6ft down in the ground. When its 20 deg F outside the ground temp is 50 deg F a great source of heat.
