Air source

Heat your home with energy absorbed from the air around you

Air source heat pumps absorb heat from the air outside. This heat is then used to warm water for radiators or underfloor heating systems, and hot water requirements.

The benefits of air source heat pumps

• Reduce your fuel bills: air source heat pumps run on a small amount of electricity, so there’s no need to pay for increasingly expensive gas, oil or solid fuels to heat your home.
• Provides 100% of your heating and hot water requirements
• Save space: an air source heat pump system is compact, and requires no storage space for fuel.
• No digging or drilling required
• Lower investment cost
• Grants available for installation

How do air source heat pumps work?

An air source heat pump works like a fridge in reverse, extracting heat from the outside air in the same way that a fridge extracts heat from its inside.

It is efficient at extracting heat from the air even when the outside temperature is as low as minus 15° C.

There are two main types:

• A monobloc; Where all of the workings of the heat pump are outside, apart from the water tank.
• A split unit; Where the air handling unit is outside, and the heat pump and water tank is situated inside the building.

There are various advantages to each of these systems, and the system most suited to your property is best discussed with our technical sales team.

Costs and savings

Costs for installing a typical system suitable for a detached home range from about £5,000 to £9,000 including installation. Running costs will vary depending on a number of factors- including the size of your home and how well insulated it is, but a typical COP for an air source heat pump is 2.5 (250% efficient), which means for every kw of energy you put in, the heat pump will output 2.5 kw of heat.

For maximum cost and carbon savings……

To reduce your home’s running costs and CO2 emissions further, consider installing …

Underfloor Heating for maximum efficiency in the distribution of heat, Solar Thermal (hot water) to provide your hot water requirements and reduce the time your heat pump is running, or Solar Photovoltaic (electricity) to contribute to powering the compressor and pump. Any of these can be integrated with a heat pump to maximise savings and minimise running costs.

Other options for bringing down your running costs include: Rainwater harvesting and Heat Recovery
