When trying to conserve energy and your wallet, one of the important factors many people overlook is weather. There is a certain ‘optimal’ HVAC system for every kind of weather, and by designing with that in mind helps to makes sure that your budget remains optimal too. Not every house needs air conditioning or furnace heaters. For instance, if you usually have moderate weather throughout the year, like we have in the Pacific Northwest, you could actually replace conventional heaters and A/Cs with heat pumps. And we generally advice our clients to go in for geothermal heat pumps. (GHP)
A heat pump works by moving heat from a warm area to a cool area. It operates on electricity and generally moves heat from the warm air outside to your cold interiors or warm air indoors to cool exteriors. Heat pumps that exchange heat in this manner are called air-source heat pumps. Overall pumps have high efficiency, in fact the highest, since they use very little energy and don’t really create heat, only move it. A geothermal pump works in a similar fashion, only, it exchanges heat with the earth, instead of air. Geothermal heat pumps move the earth’s heat through ducts into a cool house, and vice versa. Because the lower layer of the earth remains more or less at the same temperature, and is warm, GHP work in almost every kind of weather and are favored largely in extreme temperatures.
Geo Thermal Heat pumps are generally more expensive than conventional heating systems. However, the success of an installation depends on the weather, soil quality and certain other factors. Yet, over the long term, the operating costs of heat pump, especially geothermal heat pumps cost very little to operate and provide up to 300% efficiency.
