Thermal expansion - Wikipedia

Thermal expansion is the tendency of matter to change its shape, area, volume, and density in response to a change in temperature, usually not including phase transitions.. Temperature is a monotonic function of the average molecular kinetic energy of a substance. When a substance is heated, molecules begin to vibrate and move more, usually creating more distance between themselves.

Hayward HeatPro Heat Pump 140,000 BTU - W3HP21404T

The formula I use is surface area of pool x temp rise x 12= btu req to heat. the heat pump would provide the heat transfer. If solar is active, then pre-heated water would be passed through the heat pump without requiring any additional heat. Is there any way to get a ballpark calculation of how much it would run when the desired

Geothermal heat pump - Wikipedia

A geothermal heat pump (GHP) or ground source heat pump (GSHP) is a type of heat pump used to heat and/or cool a building by exchanging heat with ground, often through a vapor-compression refrigeration cycle.. It uses the earth all the time, without any intermittency, as a heat source (in the winter) or a heat sink (in the summer). This design takes advantage of the moderate temperatures in

1.2.2 Heat transfer. Heat transfer is the branch of engineering that deals with the rates of heat exchange between hot and cold bodies. The driving force for heat transfer is the temperature difference per unit area or temperature gradient. In a majority of chemical processes heat is either given out or absorbed.
