What are heat sources?

A heat source is a system from which heat is ‘lost’ to a heat sink. For example, in the built environment, a radiator may be considered to be a heat source, whilst the space around it, which it heats by a process of radiation and convection, might be considered to be a heat sink. … Water (eg water source heat pumps).

What is an example of heat source?

Typical examples of heat sources for heat networks are: gas boilers, Combined Heat and Power (CHP) plants, wasted heat (from industrial processes, wastewater treatment etc.) and biomass fuelled boilers.

What are the two main sources of heat?

There are three main sources of heat in the deep earth: (1) heat from when the planet formed and accreted, which has not yet been lost; (2) frictional heating, caused by denser core material sinking to the center of the planet; and (3) heat from the decay of radioactive elements.
