How do air source heat pumps work?

An air source heat pump will extract heat from the outside air, converting low grade heat into useable energy, by passing it through a compressor where its temperature is increased. The heat is then used for space heating and hot water. An air source heat pump will work at temperatures as low as -20°C outside.

How much money could a heat pump save you?

The suitability of air source heat pumps vary depending on the type of house you live in, levels of insulation in your home, the size of the current radiator system and whether you have underfloor heating. These are explored in our calculator giving you instant estimates on the supply and installation cost, including the £5000 BUS award. We show you estimated annual heat pump running costs and even estimated annual savings against your current heating type so you can see the potential payback period for yourself.

All of this is provided free of charge, without having to leave your email address. Should you wish to arrange a survey and to discuss this further, simply fill the form in at the end and we will be in touch for a no obligation, no-pressure discussion as to your property’s suitability for installing an air source heat pump.

Frequently Asked Questions on Air Source Heat Pumps

After carrying out a survey and completing heat loss calculations a report is compiled explaining the size of the system and estimated running costs. If you go ahead with the no obligation quote then an air source heat pump is then installed by first removing any existing cylinder and boiler. A typical installation takes around 3-4 days.

This depends on the size of heat pump required but prices start from around £6,500 + VAT for smaller properties. See our calculator to get an estimate for your property

The average lifespan of a heat pump is the same as a modern boiler, around 15 years. Annual maintenance can significantly improve the life expectancy of your system.

Very similar to a normal boiler. It is advisable to have an annual service in order to keep the warranty valid and ensure that the unit is working as efficiently as possible.

A heat pump can provide heating and hot water anytime, day or night, just like a boiler.

Yes, you can set the heat pump to heat your house to a desired temperature for specific times and dates.

Heat pumps operate most effectively when they run at a constant temperature. The radiators or underfloor heating is sized to take into consideration the specific type of heat, ensuring that the rooms get up to temperature quickly.

No, the modern heat pumps are often quieter than boilers and many other appliances we use in our everyday life.

A heat pump runs at lower flow temperatures than a traditional fossil fuel system, which results in greater efficiencies. In most cases your existing pipework will be adequate, but we might need to upgrade the output of the radiators. In many older properties, the existing radiators are single panel and we typically upgrade these to modern double panel radiators.

Heat pumps are the most efficient way to heat your home and offer large savings for those properties off the mains gas network on oil or LPG. Fossil fuel prices fluctuate significantly, but on average when you replace an oil or LPG boiler with a heat pump you can expect to save around 30% on your fuel bills.

Air source heat pumps have the capability to remain efficient even in extreme cold; they continue to function down to -20°C. As average winter temperatures in England are around 5°C, there should never be a problem. This is a very popular system in Scandinavian countries where the temperature is considerably lower for longer periods than we experience here in the UK.

Not much. The model & size of the heat pump depends on the heat requirement for the property so varies slightly. Most heat pumps are roughly 1m wide x 1m tall and sit against an external wall. Inside, the new heat pump cylinder will typically go in place of the existing cylinder.

After carrying out an in-depth survey and completing heat loss calculations a report is compiled explaining the size of the system chosen in terms of size and location in your property. To maximise the benefits of an air source heat pump, it must be correctly sized for your property, and your home should be well insulated. We assess this at the survey stage so that it does not result in wasted energy, increased electricity bills and unnecessary heat loss.
