This 2500 square foot home has a 3-1/2-ton geothermal system. The heat exchange field consists of 5 boreholes of 200-foot depth each. An in-floor hydronic radiant heating system is used throughout. Two fan-coil units provide cooling in the summer.
The domestic hot water is heated with a two-panel active solar system. This is further backed up with the de-superheater of the heat pump, the heat pump itself, and the house boiler (if ever used) resulting in unlimited amounts of hot water.
The residence is a remodeled 1894 one-room schoolhouse that also incorporates passive solar design.
