Geothermal heat pumps have a reputation for being efficient and “green”; is it deserved? In contrast, feedback from owner experience, and substantiated by discussion on industry boards and forums, paints a less flattering picture of the realities of geothermal.The specific heat capacity of building materials varies. In general, denser building materials have a higher specific heat capacity per unit of volume than less dense materials, which is why concrete, stone, and gypsum wallboard are more likely to be used to provide extra thermal mass than wood. Three analogies: cistern, frying pan, truckA standard electric water heater has a UEF of about 0.9, making my HPWH about 4.1 times as efficient.
