What is an air-to-air heat pump?
An air-to-air heat pump is an electrically powered system that provides warm or cool air directly into a room or living space.
It normally includes an outdoor unit and one or more indoor units.
Unlike air-to-water heat pumps, it does not usually connect to radiators, underfloor heating or hot water cylinders. Instead, it heats or cools the air directly.
Benefits of air-to-air heat pumps
Dual-purpose efficiency
High-performance heating for winter, with the added benefit of cooling to keep your space comfortable during warmer summer months.
Good for specific rooms or spaces
A strong option for conservatories, garden rooms, extensions, home offices, apartments and open-plan living areas.
Potentially lower running costs
May help reduce running costs depending on your current heating system, insulation, usage and electricity tariff.
Practical for homes without mains gas
A useful alternative for properties relying on electric heating, oil or LPG.
Lower-carbon heating
Because they move heat rather than generate it directly, air-to-air heat pumps can be a lower-carbon way to heat suitable spaces.
Where air-to-air heat pumps work well
Air-to-air heat pumps can be a strong option for:
- garden offices and studios
- conservatories and extensions
- apartments and smaller homes
- homes without mains gas
- open-plan living areas

Is air-to-air right for your property?
Air-to-air heat pumps are not right for every home or every heating requirement.
They may be suitable if:
- you want to heat and cool a specific room or area
- you have a conservatory, garden room, extension or home office
- your property is well insulated
- you do not have mains gas
- you currently rely on electric heating, oil or LPG
- you want clear advice before committing to a survey
They may be less suitable if:
- you need full whole-house heating and hot water replacement
- you prefer radiator-based heating
- your property is poorly insulated
- the outdoor unit location is not practical
- planning or property restrictions apply
We provide a professional assessment to make sure an air-to-air heat pump is the right financial and practical decision for your property. If it isn’t, we’ll tell you.
Air-to-air vs air-to-water heat pumps
Air-to-air heat pumps
Heat or cool the air directly. Best suited to specific rooms, living spaces, apartments, garden rooms or properties without a traditional radiator system.
Air-to-water heat pumps
Heat water for radiators, underfloor heating and hot water cylinders. Better suited to whole-house heating and hot water replacement.

Air-to-Air Heat Pump & Air Conditioning FAQs
Air-to-air heat pumps are highly efficient because they move heat rather than generate it. In many situations they can provide three to four units of heat for every unit of electricity used. Running costs depend on your home, insulation levels, how often you use the system and your electricity tariff, but they can often be a more economical alternative to direct electric heating.
Yes. Air-to-air heat pumps provide both heating and cooling, making them an excellent year-round solution. During summer they work like an air conditioning system, helping keep bedrooms, home offices and living spaces comfortable during hot weather.
In some homes an air-to-air heat pump can provide most or all of your heating requirements, particularly in well-insulated properties, apartments, garden rooms and open-plan spaces. However, because they do not provide hot water or connect to radiators, they are not always a direct replacement for a traditional central heating system. Our renewables team can advise on the best solution for your property.
In most cases, no. Generally, you will not require planning permission to install an air-to-air heat pump. These can be installed under permitted development rights. Exceptions can include listed buildings, conservation areas or properties with planning restrictions.
Modern air-to-air heat pumps are designed to operate quietly. Indoor units typically produce no more noise than a gentle fan, while outdoor units generate a low humming sound. Correct system design and installation will ensure noise levels remain unobtrusive.
Typically, a high-quality air-to-air heat pump that is correctly installed and maintained can last between 15 to 20 years. Regular, professional servicing will help to preserve efficient running, protect any potential warranties that came with the product and can minimise the number of any repairs that may be needed across the lifetime of the system.
Yes. A multi-split system allows one outdoor unit to connect to several indoor units, providing independent heating and cooling to multiple rooms. This makes them ideal for homes where different rooms have different comfort requirements.
Single-room systems typically start from around £2,000–£3,000, while multi-room systems can cost more depending on the size of the property and the number of indoor units required.
No. Air-to-air heat pumps are among the most efficient forms of electric heating and can often be significantly cheaper to run than direct electric heaters.
Yes. Many systems allow individual temperature settings in each room, helping improve comfort and reduce energy usage.
Yes. Air-to-air heat pumps are increasingly popular in bedrooms because they provide both cooling during summer and efficient heating during winter.
Absolutely. They are one of the most popular heating and cooling solutions for garden rooms, home offices and extensions.
