Geothermal Heat Pumps
Geothermal heat pumps have been in use since the late 1940s.
Exhanges heat with the earth through a ground heat exchanger.
Uses the constant temperature of the earth as the exchange medium.
Ground remains at a relatively constant temperature around 60F in Richmond.
Geothermal heat pumps are able to heat & cool.
Very High efficiencies (300%-600%) on the coldest of winter nights (compared to 175%-250% for air-source heat pumps on cool days).
Additional costs are returned to you in energy savings in 5–10 years.
System life is estimated at 25 years for the inside components and 50+ years for the ground loop.
40,000 geothermal heat pumps are installed in the US each year.
Benefits of Geothermal Heat Pumps
Uses 25%–50% less electricity than conventional heating or cooling systems.
Reduces energy consumption and emissions up to 44% compared to air-source heat pumps.
Excellent "zone" space conditioning.
No blasts of cold or hot air.
Durable and highly reliable.
No outdoor compressor - less susceptible to vandalism.
Requires less space than that needed by conventional HVAC systems.
