What is An Air Source Heat Pump

 

An air source heat pump is an efficient means of heating and cooling your home or business. Air source heat pumps They run on electricity and use the air temperature outside to heat or cool a building. They have a refrigerant system that consists of a condenser and a compressor. Basically it absorbs heat in one location and releases it in another. These pumps are primarily used to heat a building, but they can also be used to cool one. In areas of moderate temperatures, they can provide all the heating and cooling needs for a building. They are also used to heat water, and they can generally heat water up to 80ºC. Sometimes they have to be paired with more traditional means of heating water because their efficiency can drop in very cold temperatures.

In the winter, they extract heat from the air outside and release that heat into the house. During the summer, it can absorb the heat in the air from inside the building and release it outside. Most standard pumps only work well in positive temperatures. Once the temperature drops below freezing, it becomes very difficult to extract heat from the air. Some pumps have been developed to cope with colder temperatures; however, these pumps are most 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 extracts heat from the air. The other coil is located inside, and it releases heat into a water tank or a heating system, such as an under the floor heating system. Refrigerant is located in these coils and flows through the system absorbing and releasing ambient heat. These pumps are durable, often lasting twenty or thirty years, and they are more efficient than traditional electric heaters. They are more expensive than traditional systems, and they often have to be paired with propane (or other source) heating systems just in case it gets too cold for the pump to function.

The efficiency of these pumps is measured by something called the coefficient of performance, which is measured in units. For example, most heat pumps produce three to four units of heat for every one unit of electricity they use. While these pumps are expensive to buy and install, they can cut your heating costs significantly because you are not generating heat, you are simply moving it from one place to another. Ground source and water source pumps do the same thing that an air source pump does, but they are often more expensive. For example, to install a ground source heat pump, you have to excavate and install the coil in the ground.

Currently the government offers a Renewable Heat Premium Payment where homeowners can receive a onetime payment to help pay for the installation of an air source heat pump. In the fall of 2012, the government plans to introduce tariffs for renewable heat which will be an additional payment for people who choose to install heat pumps.
