The Basics: Air Source Heat Pumps Explained
An Air Source Heat Pump (ASHP) is a modern heating system that uses heat from the outside air to warm your home and provide hot water. Even when it feels cold outside, there is still energy in the air, and an ASHP captures that heat and boosts it to a higher temperature.
You can think of it as working like a fridge in reverse. Instead of removing heat from inside, it takes heat from the air outside and brings it indoors, providing steady, reliable warmth without burning gas or oil.
A unit installed outside your home draws in air, and an efficient electric compressor transfers the heat into your central heating system, such as radiators, underfloor heating or a hot water cylinder. For every unit of electricity it uses, an ASHP can produce more than three units of heat, making it over three times as efficient as a typical boiler. Even in winter, it can extract enough heat from the air to keep your home comfortable all year round.
The Benefits of Switching to an Air Source Heat Pump
Making the switch to an air source heat pump comes with plenty of perks for homeowners:
- Lower Energy Bills: By moving heat rather than generating it from scratch, ASHPs use much less energy than traditional heating. Many homeowners see significant savings on their heating costs, potentially cutting bills by around 40% when replacing old electric heaters.
- Energy Efficient and Eco-Friendly: Heat pumps are a green energy solution. They reduce your carbon footprint by eliminating on-site fossil fuel use, helping you lower CO₂ emissions while still keeping warm. It’s a win for you and the environment.
- Year-Round Comfort: Enjoy a cosy home through the winter and consistent hot water all year. An ASHP works in cold temperatures and provides steady, reliable heat in every season. Some models can even cool your home in summer for extra comfort.
- Low Maintenance and Long Lifespan: Air source heat pumps are built to last, often 15 - 20 years or more. They have few moving parts and generally only need a simple yearly service to keep running efficiently, giving you peace of mind with minimal upkeep.
- Grant Eligibility: Upgrading to an ASHP comes with a potential bonus: you may qualify for government grants or funding support (like Warm Homes:Local Grant or the Boiler Upgrade Scheme), which can significantly reduce the upfront cost of installation. In many cases, you could even get a heat pump fully funded at no cost to you if you meet certain criteria. Use our easy postcode checker in the link below to find out if you qualify.
