Heating units exist for various sorts of fuel, including solid fuels, liquids, and gases One more type of heat resource is electrical power, typically heating bows made up of high resistance cord (see Nichrome ). This concept is likewise utilized for wall heaters and portable heaters Electric heating units are often used as backup or additional warmth for heat pump systems.
