Co się stało z Are Geothermal Heat Pumps?

Geothermal heat pumps, also known a foremn as ground-source heat pumps, work by transferring heat between a building andthee ground. The earth maintains a nexly constant temperatur - typically between 45 ° F and 75 ° F dependiing on laetardede - juste a few feet below the surface. In winter, a GHP extracts heat frem the ground d contricates it into the building; in more moreverses thee process, pulling heat frem the builg and depositineng inte cour courd.

Te cory continued include a ground loop (a buried network of pipes fillet with water or antifreeze), a heat pump unit (located inside thee building), and a distribution system (such as radiant floors or forced air).

Efficiency is measured by the coefficient of performance (COP) for heating and thee energy efficiency ratio (EER) for cool. Modern GHPs routinely accessone COP of 3.5 to 5.0, meaning they deliver 3.5 to 5 units of heat for every unit of electricity consumed. This is a dramatic improwistement over conventionale electric resistance heating (COP of 1.0) and even highefficiency gas boilers (typically 95).
