Air Source Heat Pump USPs

How It All Works

Heat pumps operate entirely off of electrical power, and will generally use 50-60% less energy than a gas mains supply. The general process is not actually too different from traditional boilers, the main difference is how they generate heat.

Traditional boilers burn some kind of fossil fuel, whether that be natural gas, coal or oil. This combustion method is functional but it’s not particularly efficient. It can also be dangerous, resulting in a higher risk of carbon monoxide poisoning and other leaks.

Air source heat pumps instead draw air in from the outside of your house, which it then passes through a series of extra stages, including a compressor and a heat exchanger, before it is used to heat up water. This water is then transported throughout your home, just like in a traditional central heating system.

How Do Air Source Heat Pumps Work

Versatile Heating All Year Round

Air source heat pumps provide you with all the heating functionality of a traditional boiler. They can provide heat through radiators and supply you with plenty of domestic hot water.

That last part is what sets heat pumps apart from other electric heaters, you won’t need a secondary system to provide you with plenty of hot water for your shower, the heat pump can handle all of it!

Pairing a heat pump with underfloor heating is a particularly popular upgrade, making for effortless low-cost heating that can easily spread throughout your home.

However, it’s not just heating that a heat pump can provide. Our Air Source Heat Pumps can also provide cold water circulation, which is especially handy for underfloor heating systems in the summer, providing a cooler floor to walk on.

Heat Pumps Designed For You

Air Source Heat Pump Range

The 12kW model is a good all-round fit that’s well-suited to many homes in the UK. However, we’d recommend getting in touch with our team of experts and telling us about your heating needs, so we can consider all the variable factors and recommend the perfect heat pump for you.

If you have a very small and well-insulated property, then the Mirrorstone 9kW Air Source Heat Pump 1 Phase is a good alternative, as it uses minimal power, which reduces the chance of wastage.

If you need a little extra kick, perhaps because your property is a little larger than the UK average, then the Mirrorstone 20kW Air Source Heat Pump could be a better choice.
