Live Solar Hot Water Data

Crossroads House In Portsmouth NH has a large solar hot water system installed on their brand new building. On the roof are 16 flat plate collectors and they are connected to a 900 gallon storage tank. The data below shows temperatures at the cold input to the collectors, the hot output from the collectors, the tank temperature, the hot water temperature leaving the tank and the solar output. Even in the winter we are seeing tank temperatures that will substantially lower their hot water fuel bills.
