Introduced: January 2018
Description
F24T covers devices and systems that extract and utilize thermal energy from the Earth's subsurface for heating and cooling applications. This includes ground source heat exchangers, borehole heat collectors, closed-loop and open-loop geothermal circulation systems, and associated piping and heat transfer arrangements. The classification encompasses both the collection apparatus and integrated geothermal heating/cooling systems for residential, commercial, and industrial buildings. Related heating technologies using conventional or renewable sources are classified elsewhere in F24.
