Air Source Heat Pumps
This type of heat pump serves as a great alternative to conventional heating systems, as they enable you to generate your own heat and could help you to reduce both your energy bills and your carbon footprint. But what exactly are they and why should you choose one?
What is an air source heat pump system?
An air source heat pump can be a low-carbon form of central heating that moves heat from a natural outdoor element, such as the air, into your home when used in conjunction with renewable energy sources. They can take heat from outside in temperatures as little as -15 degrees and convert it into usable heat, with the help of electricity, to provide you with underfloor heating or hot radiators.
These appliances work by generating heat from the environment using a similar principle to a refrigerator, only in reverse. A fridge works by extracting warmth from the contents of the appliance, therefore reducing the temperature. An air source heat pump instead uses the heat from outside and brings it into your home.
For this process to occur, a fan is used to draw air across a heat exchanger (or evaporator). The heat in this air is transferred to a refrigerant circulating through the evaporator causing it to change from liquid to vapour. A compressor, using electricity, then compresses this vapour causing it to rise in temperature. At this high temperature, the heat is then suitable for transferring to the heating and hot water systems in your home.
Air source heat pumps have an outdoor unit that is installed outside your home, the size you require will depend on the size of your home, the number of people living there and your heating and hot water demands.
