What to know about air-to-air heat pumps in Daventry
In Daventry, as anywhere in the UK, the heat pumps that perform well are the ones designed around low flow temperatures and sized from a proper heat loss calculation.
Top-floor rooms in Daventry that overheat in summer gain from the cooling an air-to-air system provides. A survey in Daventry covers indoor unit positions, pipe routes and hot water for homes across Northamptonshire.
An air-to-air heat pump warms rooms directly with air, and can cool them in summer, but it does not heat your hot water.
- Flats and apartments with storage or panel heaters
- Extensions, conservatories and garden rooms
- Homes where fitting radiators and pipework would be very disruptive
What's included
- Electrical supply and controls set up for each room
- Refrigerant pipe runs to each indoor unit, made and charged by an F-gas certified engineer
- Condensate drains and neat external pipe covers
- Outdoor unit and indoor units for each room
- Free survey covering rooms to heat, unit positions and hot water options
For terraced homes in Daventry, the outdoor unit can often sit in a rear yard with tidy pipe runs to each room.
Grants and rules for heat pumps in England
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your Daventry quote.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Since 29 May 2025, permitted development in England allows up to two air source heat pumps on a house, each up to 1.5 m³, with no blanket 1 m boundary rule — the installation must still meet the MCS planning standards, including the noise check. Listed buildings, flats and some conservation-area positions need extra consent, which we check at survey.

Short winter days in Daventry and what they mean
On the shortest day Daventry gets about 7 hours 42 minutes of daylight, with the noon sun around 14° up. The heating season runs from autumn into spring, so a heat pump that is sized correctly and set up with weather compensation does most of its work in steady, cool conditions.

- The system is commissioned, set up with weather compensation and handed over with the paperwork.
Air-to-air heat pumps in Daventry: questions
Do I need new radiators for a heat pump in Daventry?
Often some, not all. Heat pumps run best at lower water temperatures, so rooms with small radiators may need larger ones. The survey of your Daventry home gives a room-by-room list.
Do you cover Towcester as well as Daventry?
Yes. We arrange surveys and installation in Towcester, which is about 11 miles south-east of Daventry, and across Northamptonshire.
How long does installation take in Daventry?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Daventry home states the expected time.
How do I look after an air-to-air system?
Clean the indoor unit filters regularly, typically every few weeks during heavy use and following the manufacturer's guidance, and keep the outdoor unit clear of leaves and snow. Annual servicing is recommended and is often a condition of the manufacturer's warranty. Any work on the refrigerant circuit must be done by an F-gas certified engineer.
Can an air-to-air heat pump heat my water?
No. An air-to-air heat pump heats and cools the air in rooms but does not produce hot water. You need a separate source, such as an existing immersion cylinder, a hot water heat pump or an electric water heater. If you want one system for heating and hot water, an air-to-water heat pump with a cylinder is the alternative.
