The Campbells were concerned about the impact fossil fuel combustion was having on the environment, as well as their high energy bills. In 2010 they made adjustments. They abandoned coal for a six ton, horizontal, ground source heat pump and then improved their home performance by adding foam insulation. An 8,750 watt solar photovoltaic unit was installed in 2012. The homeowners note the added comfort and safety of their home after making this transition. They now have the added benefit of air conditioning and can avoid the risks associated with burning fossil fuels.
The home is now within 85% of being net zero, nearly making as much energy as it produces! The Campbell's explain they are able to “heat their home at a fraction of the cost they had previously been paying.” They add that “after some initial issues with installation, the system has exceeded our expectations.”
Installation and Energy Details
Prior Energy system: Coal
Prior Insulation or Sealing: None
New Energy System: Ground source heat pump (GSHP); solar photovoltaic; wood pellet stove
New Insulation or Sealing: Foam insulation after installation of heat pump.
- Ground Source Heat Pump: Gleason Geothermal GeoComfort 6-ton pump, air/whole house, with 6 horizontal loop 500-foot runs. Installed August 2010.
- Solar PV: 8,750 watt, installed 2012.
Net Zero? No, but within 85%
- The homeowners are able to heat their home at a fraction of the cost previously paid.
- There were some issues with the process of installation, but in the long run, the results have exceeded the homeowners’ expectations.
- Additional comfort from air conditioning.
Motivation for Heat Pump Technology
- Environmental sustainability was a large factor in the homeowners’ decision to install geothermal technology.
- Reduction of fossil fuel use for heating because the costs are quite volatile.
- Comfort in an old house where the homeowners had formerly not had air conditioning.
- The ability to avoid fossil fuel combustion in the home and avoid the risks associated with it.
