Air-to-air heat pumps in Leamington Spa
Have a room in Leamington Spa that is cold all winter and hot all summer? We fit air-to-air heat pumps that deal with both from one wall unit. They suit homes and flats where radiators fall short or plug-in heaters are running up the bill, and they work alongside the boiler you already have.

What is an air-to-air heat pump?
Think of a reversible air conditioner. The refrigerant collects heat from the outside air, even on a cold day, and releases it into the room. In summer the flow reverses. Nothing burns, and the electricity runs the compressor and fans instead of making the heat directly.
How does the running cost compare?
| Heat source | Cost of 1 kWh of heat |
|---|---|
| Plug-in electric heater | 26.32p |
| Gas boiler | 7.97p of gas, plus boiler losses |
| Air-to-air heat pump at an efficiency of 4 | About 6.6p |
Unit rates are the Ofgem price cap for October to December 2026, and they change every quarter. The efficiency is the Energy Saving Trust's description of typical seasonal performance, and a real figure depends on the unit, the weather and the room. The clearest saving is against direct electric heat. Against gas, it is much closer. Sources: Ofgem; Energy Saving Trust.
Can it replace my boiler?
Rarely on its own. The Energy Saving Trust points out that air-to-air systems are not generally designed to meet hot water demand, so you still need something else for taps and showers. You also lose the radiant warmth of a hot radiator, and air has to be able to move between rooms. The usual arrangement is to keep the boiler and use the heat pump where it does most good.
Which homes around Leamington Spa suit one best?
- Flats with electric heaters and no gas supply.
- Loft rooms and extensions that the radiators never reach properly.
- Rooms that overheat in summer, where you were going to fit cooling anyway.
- Garden rooms with no heating at all.
Tall Regency rooms are harder, because warm air gathers at the ceiling. A survey can tell you how much that matters in your room.
Does being reversible help with planning?
It does. Since 29 May 2025, air-to-air units have been able to use the permitted development rights for heat pumps, with larger size limits and no one-metre boundary rule. The catch is that the unit must not be used solely for cooling. A cooling-only unit falls outside those rights. Listed buildings, conservation area frontages and flats over shops have their own limits, covered in the planning guide. Sources: MCS; Planning Portal.
Common questions
Does it work in a hard frost?
Yes, though output falls as it gets colder and the unit will pause now and then to defrost. Wellesbourne averages about 47 air frost days a year, so it needs sizing with cold mornings in mind.
How is it different from an air source heat pump on radiators?
That type heats water for radiators and taps. This one heats the air in the room directly, and can cool too.
Does it heat the whole house?
One unit heats one room. A multi-split can do several rooms, but air still has to move around the house and hot water needs its own source.
