Northeast Boulder Retrofit

This house is a 2,100 square foot, split-level home in northeast Boulder, built in 1969. 

Valley Geothermal (now Blue Valley Energy) installed a WaterFurnace E-series to replace the existing furnace.  The system is still running strong after 5 years and cut the heating and cooling energy use by over 70%.  The geothermal unit also features a hot water “desuperheater”, which, in conjunction with a new Conservationist water tank, has cut the domestic hot water energy use by approximately 50%.
