Residential Case Study
In 1999, this 2,000 sq. foot Energy Crafted Home* in Bow, NH is equipped with a 4-ton “Classic” heat pump from Climate Master (The ClimateMaster “Classic” geothermal heat pump is now two generations of heat pump old – newer models are significantly more efficient). Water for the forced air system is drawn (and returned) from its standing column well. The home qualifies for the “Heat Smart” program run by PSNH and receives electricity at a lower rate for the well pump, heat pump, and hot water.
Actual costs to heat, cool, and provide hot water for 2007 was $867 (PSNH smart geo rate of 10.3 cents /kwh). See a detailed spreadsheet showing actual costs for the whole year 2010-2011.
