Energy and Thermal data for Bethencourt Residence - WEL0444


Bethencourt Residence : Southington, CT USA

We have a 4-ton ground source heat pump (GSHP) Envision Series from WaterFurnace that was installed in the fall of 2008 to heat & cool our home. The system has a closed loop with a pressurized GeoLink Flow Center FC2-FPT with two Grundfos pumps (TYP UP 26-99) and 3 vertical bores at 225 feet each with 1.25'' HDPE pipe. The geothermal loop is running with methanol diluted at 20%. The GSHP is controlled by a TZ-4 TotalZone Zone Control panel from Honeywell.

We also have a Marathon (MR50245) 50 Gallon 4500 Watts Electric Water heater.

Our house was built in 2002. The house is 2500 square feet with 2'' by 6'' framing on exterior walls and R19 insulation. The attic has R30 insulation. The house has Andersen Windows with high performance glass.

The geothermal heat pump replaced an inefficient Hallmark oil fired furnace. The Marathon water heater replaced a Bock oil water heater. We have cut our dependency on fossil fuels as we no longer need oil to heat our home or our domestic hot water.

We have been researching the WEL for awhile. We are hoping to get a better understanding of how our system is performing and monitor in greater detail our temperature sensor data and monthly heating and cooling costs.
