Heat energy from the earth's core

WebMost heat pumps have the ability to extract heat from the air down to -5 °F. The colder it is, the less heat the heat pump can obtain. The lower the temperature the less efficient an air-to-air heat pump becomes, and at -5 °F, the air-to-air heat pump will not extract heat from the air. Therefore, there needs to be a form of backup heat in ... WebThe energy reaching the surface of the Earth from within can be measured to get heat flux, q.. q = - k dT/dz . Units of heat flux = Wm-2 which is equivalent to Js-1 m-2, and k is the thermal conductivity (Wm-1 K-1). The average heat flow from the Earth gives a q of approximately 0.08Wm-2 (equivalent to 80mWm-2).. But the flow is very uneven.
