Air-To-Air Heat Pump

Air-to-Air Heat Pumps

High-performance heating and cooling for your home

What is an air-to-air heat pump?

An air-to-air system is an electric low-carbon solution that takes outside air, compresses it and uses it to heat your home, much like an air-to-water heat pump system. During the summer, it works in reverse to cool your home.

The main difference between an air-to-air and air to water system is, air-to-air rather than sending the heat to after in your radiators which then heats your home, it goes through ducts straight to the air in your home.

How Does It Work?

An air-to-air heat pump can provide both cooling in summer and heating in winter by moving heat from one place to another rather than generating it.

Air-Conditioning Mode

When the unit is used as a cooling system, the indoor unit draws in warm air from your home using a fan.
This heat is transferred to a refrigerant, which absorbs the heat energy as it passes through the indoor unit.
The refrigerant carries the heat to the outdoor unit, where it is released into the outside air.
With the heat removed, the indoor unit circulates cool, refreshing air back into your home. The refrigerant then returns to the indoor unit to repeat the cycle.

Heating Mode

When used as a heating system, the outdoor unit draws in outside air using a fan. Even on cold winter days, the air contains heat energy that the system can absorb.
This heat is transferred to a refrigerant, which absorbs the heat energy before being compressed. Compressing the refrigerant significantly increases its temperature.
The hot refrigerant travels to the indoor unit, where the heat is transferred into your home. A fan then circulates warm air throughout the room, providing comfortable, efficient heating.
After releasing its heat indoors, the refrigerant cools and returns to the outdoor unit, where it absorbs more heat from the outside air. This continuous cycle keeps your home warm.

Benefits of Air-to-Air

Year-Round Comfort

Enjoy efficient cooling during the summer and reliable heating throughout the winter, all from one system.

Ideal for Smaller Properties

Compact outdoor units make them well suited to flats, apartments and homes where space is limited.

Low-Carbon Solution

An energy-efficient alternative to traditional heating and standalone air conditioning, helping to reduce your home's carbon emissions.

Solar Compatible

If you have solar panels, your system can use the electricity they generate, helping to reduce running costs even further.

Supplementary Heating

Install an air-to-air heat pump as your primary heating and cooling system, or keep your existing heating system and use it for air conditioning with the added benefit of efficient backup heating.

How will I heat my hot water?

An air-to-air heat pump only heats and cools the air within your home, it does not provide domestic hot water. However, we can install an electric hot water cylinder with an immersion heater to supply your hot water independently.

If you’re already using an existing hot water cylinder or an air-to-water heat pump for hot water, these can often continue to be used alongside your new air-to-air system. We’ll assess your current setup and recommend the most suitable solution for your home.

can i add a2a indoors units to my existing a2w system

Unfortunately not. The air-to-water outdoor units are not compatible with the air-to-air indoor units, so you would need upgrade the whole system.

Can i get any government grants towards my installation

There is a £2,500 BUS grant towards the installation of an air-to-air heat pump system. Please see the BUS page for more information.
