Heating systems exist for different sorts of gas, consisting of solid fuels, liquids, as well as gases An additional type of warm resource is power, generally heating ribbons composed of high resistance wire (see Nichrome ). This concept is also utilized for baseboard heating units and mobile heaters Electrical heaters are commonly utilized as backup or extra warmth for heatpump systems.
