There are a lot of different types of heat pumps on the market which can distribute heat and these almost always have an auxiliary source of heat that will be relied on for back up if the pump itself fails to produce enough heat to keep the unit functioning the way it should. In addition to oil, natural gas or electricity, there is also the option to use the more green technology of geothermal heat backup in order to work alongside the heating pump and keep a house or other building properly heated. Not only is a pump that produces heat like this used to heat air up so that it can be blown throughout a building, there are also those which are designed to heat up the water in a home, swimming pool or other location that operate on a very similar principle to the forced air heating system.
