Air source heat pump work on the principle of absorbing energy from the air outside and converting it to usable heat which then circulates around the household. This is usually used to heat radiators, under floor heating systems, or warm air convectors and hot water in your home.
Air source heat pumps usually perform better at slightly warmer air temperatures. Air source heat pumps are the most common heat pumps used in domestic and commercial buildings as these are easier and cheaper to install. They are an ideal solution for places where space constraints may not permit the installation of other renewable energy systems.
There are two main types of air source heat pump system:
In Air-to-water system, the heat generated by the pump is distributed through central heating system.
Air-to-air system produce warm air as well air, but the heated air is circulated directly around the household by powerful fans. These units are often wall-mounted.
The advantages of using Ground source Heat pump are that it is convenient to install it both in new buildings and in case of renovation. Suitable means of providing heat and hot water for your home. It is very energy efficient and possesses both cooling and heating modes. It can extract heat from the air even when the outside temperature is very low. It takes no extra cost for fuel. It can reduce the level of carbon emission. Air source heat pumps can lead to a significant reduction in heating bills.
But there are certain disadvantages as well. The performance of air source heat pumps will be affected by extreme low temperatures. They are not suitable for very old buildings unless they are well installed and draught proofed. It requires outdoor installation and a large area of open space to ensure good flow of air. It often creates background noise.
