An air source heat pump is an efficient way of cooling and heat your home or business. They run on electricity and use the air temperature outside to heat or cool a building. They have a refrigerant system which consists of a compressor and a condenser. Fundamentally it absorbs heat in a single place and releases it. These pumps are mostly used to heat a building, however they can be used to cool one. In areas of average temperatures, they are able to supply all the heating and cooling needs for a building. They're also used to heat water, and they are able to usually heat up water to 80ºC. Occasionally they have to be paired with more conventional method of heating water because their efficacy can drop in very cold temperatures.


In the winter, they release that heat into the home and extract heat from the atmosphere outside. During the summer, it can consume heat in the atmosphere from inside the building and release it outside. Most pumps that are standard just operate very well in temperatures that are positive. It becomes very difficult to extract heat from the atmosphere once the temperature drops below freezing. Some pumps have been developed to cope with colder temperatures; nonetheless, these pumps are efficient in areas with mild to moderate winters.


An air source heat pump is made up of two heat exchanger coils. One is located outside, and it pulls heat from your atmosphere. Another coil can be found in, and it releases heat into a water tank or a heating system, including an under the floor heating system. Refrigerant can be found in flows and these coils through the system consuming and discharging heat that was ambient. These pumps are durable, often lasting twenty or thirty years, and they're better than conventional electric heaters.


Something known as the coefficient of operation, which is measured in units measures the efficacy of the pumps. For instance, most heat pumps produce a few units of heat for every one unit of electricity they use. While these pumps are not cheap to buy and install, they are able to cut your heating costs significantly because you are not generating heat, you are just transferring it from one place to another. Water source pumps and earth source do the same thing that an atmosphere source pump does, however they are generally more costly. For instance, to use a ground source heat pump, you have to excavate and install the coil in the bottom.


In the fall of 2012, the government intends to introduce tariffs for renewable heat which will be yet another payment for those who opt to install heat pumps.
