The Clausen home in Tully was built in 1923 and had an addition added in 1980. Before going geothermal, they heated with expensive fuel oil. They went geothermal with vertical wells in 2016, using in-floor and baseboard radiant heat in a water-to-water system. Combined with their solar panels, they pay next to nothing each year for electric or heat!
ALLERGY NOTE: This is a house with dogs.
The Clausens blogged through their installation process- you can read all about it here!
