How Does an Air Source Heat Pump Work

The UK has a net-zero target to achieve by 2050. This means significant efforts are being made to cut greenhouse gas emissions and we can all play our part in protecting the planet. For households, switching from an old boiler to an air source heat pump can save both money and emissions. But what exactly is a heat pump and how does it work? Let’s find out more.

What is an Air Source Heat Pump?

An air source heat pump is a new kind of low-carbon heating solution. It runs on electricity, not gas, making it an environmentally friendly alternative to old boiler systems. Heat pumps take warmth from the air outside (even during sub-zero conditions) and use it to supply your home’s heating and hot water. For properties that are already well-insulated, they can create a cosy, warm living environment and can even be paired with solar panel systems for optimum efficiency. Larger, draughtier homes might require a hybrid system which combines an air source heat pump with an eco-friendly boiler. The boiler will only kick in when necessary to ensure emissions are kept to an absolute minimum. Your local heat pump and boiler installer will be able to offer the help and advice you need, depending on your property.

How do Air Source Heat Pumps Work?

Air source heat pumps work by pulling in air and using it to heat a refrigerant liquid. It’s like a refrigerator system but in reverse. As it warms up, the liquid turns into a gas (just like a kettle produces steam when water is boiled). The warmth is then compressed to increase its temperature and is used to warm your home. Once the heat from the gas has been used, it cools, becomes a liquid again and the cycle starts over. Air pumps have an energy efficiency rate of over 350% compared to the 90% efficiency of a gas boiler.

What are the Benefits of a Heat Pump System?

There are many benefits to heat pump installation. Firstly, heat pumps cut CO2 emissions and improve local air quality which all helps to achieve the government’s net-zero target. Secondly, heat pump servicing is minimal. Only an annual service is recommended to keep things working properly. Heat pump cover is also available to help with maintenance costs and repairs. Heat pumps work in most weather conditions, so you won’t have to worry about them packing up in winter. In fact, they’re still operational at -15 degrees.

Moreover, government grants are available to incentivise people to take the leap to a more efficient future. You could be eligible for one, so it’s worth finding out more today.
