Solar Heat in Wisconsin

At 9am this morning it was 7F degrees outside, but not a cloud in the sky. The solar fluid pumping into the domestic hot water and radiant floor heat was 95F degrees. Now at 10am it is 9F degrees outside and the solar fluid temp is 105F degrees.

On days like these the house will see a high temperature of 70F degrees.

This morning the panels were frost covered, but it doesn't take long for the frost to melt away and the solar electric panel to start pumping the hot fluid in the house.

In the summertime this system has over 400' of shunt to dissipate the heat and prevent the system from overheating, but still keep the domestic hot water nice and HOT.
