How does an air source heat pump work?
An air source heat pump takes heat from the air and boosts it to a higher temperature using a compressor. It then transfers the heat to the heating system in your home. They work like refrigerators in reverse. The air source heat pump absorbs heat from the outside air into a liquid refrigerant at a low temperature. Using electricity, the pump compresses the liquid to increase its temperature. It then condenses back into a liquid to release its stored heat. Heat is sent to your radiators or underfloor heating. The remainder can be stored in your hot water cylinder. You can use your stored hot water for showers, baths and taps. The pump uses electricity to run, but it should use less electrical energy than the heat it produces. This makes them an energy-efficient way to warm your home. Air source heat pumps work even if the temperature is well below zero. Ground source heat pumps also harness natural heat and increase the temperature to warm your home.
What is an air source heat pump?
Air source heat pumps are a greener
alternative to boiler heating systems. They’re low maintenance and highly
efficient. Air source heat pumps look a bit like air-conditioning units and
their size depends on how much heat they'll need to generate for your home. The
bigger the heat pump, the more heat is produced. Air source heat pumps use one
simple, renewable resource as their main source of energy is air. They take
energy from the air outside (even when it’s cold) and convert it into heat for
your home. Basically, they work just like fridges and air-conditioning units
just in reverse.
Air source heat pump installation
Air source heat pumps are usually
positioned outdoors at the side or back of a property. They need plenty of
space around them for air to circulate. Inside, you'll usually have a unit
containing pumps and hot water. It's usually smaller than a standard boiler. They
are less disruptive to install than ground source heat pumps, as they do not
require any digging in your garden. Check first whether you will need planning
permission for an air source heat pump. If you live in a listed building, then
you'll usually need the consent of your local authority. Also check that your
installation will meet the building regulations in your area.
What is a heat pump system?
The pump absorbs naturally occurring heat from the air, earth, or
water outside, and uses this to heat your home and give you hot water. Since it
transfers heat, rather than generating it, heat pumps are one of the most
efficient means of warming your house.
Types of air source heat pumps
Air-to-water systems: these distribute heat by pumping liquid
through pipes and radiators, or through underfloor heating pipes. This is the
most common type, and it can be used for both heating and hot water.
Air-to-air systems: these produce warm air, which is circulated
around your home by a network of fans.
