CO2 emissions and high power costs are major topics of concern for everybody these days. Ground source heat pumps are used to reduce both carbon footprint and heating costs for homeowners. Useful heat energy can be extracted from the ground throughout the year to extract eco-friendly heat energy which can be used to produce heat energy for heating homes and commercial buildings. Ground temperatures in most locations are relatively constant thoroughout the year. In the majority of locations useful heat energy can be extracted even if external air temperature drops below zero.
Once installed, geothermal heat energy extracted by a ground source heat pump is used to provide lower heating costs and smaller CO2 emissions for homes and commercial buildings. Carbon emissions from a ground source heat pump are usually less than outputs from the more common gas-fired, oil-fired or electric heating.
A ground source heat pump system utilizes identical technology to how a standard domestic refridgerator. Heat energy is extracted from the contents of the refridgerator. In the case of a refidgerator heat extracted is simply dissipated as waste heat. In the case of a ground source heat pump the extracted heat is useful heat energy which is used to provide heating for a building or to provide a hot water supply.
Common alternatives to ground source heat pumps are air source heat pumps which extract heat energy from the air and water source heat pumps which derive heat from ponds and watercourses.
