How does an air-to-water heat pump work?
A heat pump takes energy from the outside air, even at very low temperatures, and transfers it into heat that is then circulated around a heating and hot water circuit. A heat pump uses electricity to power a compressor that boosts the temperature of the water so that is hot enough to warm your home through under-floor heating or radiators as well as fulfill your hot water needs.
What are the main benefits of heating with heat pumps?
Heat pumps extract up to 70% of their energy freely from the air meaning they only use a fraction of the electricity other systems use. Heat pumps are up to 500% efficient, compared to a traditional boiler that is 92% efficient, so significant energy savings are made which reduces energy bills. Heat pumps are a renewable energy source so are a great option for households looking to reduce their carbon footprint. Ideal for off-gas areas as users will see considerable running cost savings against oil boilers. Heat pumps don't use any fossil fuels or generate any fumes so won't affect the air quality in the local area. Maintenance is simple and low-cost. What size air source heat pump do I need for my house?
It depends on the difference between the outside temperature and the water temperature required to heat the house. A heat pump will use more electricity the bigger the gap between the outside temperature and the water temperature needed to heat the home. It will always be more efficient to use the lowest flow temperature possible as this reduces this difference. Contact an installer and get further information.
Can a heat pump heat a whole house?
Heat pumps are designed to cover the full thermal requirements of your home at a design temperature that is unique to the geographical area you live in. This will ensure that even in the coldest winters the heat pump will ensure the comfort of all occupants. Heat pumps can continue to provide their full capacity even at temperatures as low as -20ºC.
