Air source heat pumps can provide efficient low-carbon heating when the building, emitters and controls are designed as one system. Historic streets, mature neighbourhoods and modern homes create different priorities for fabric, appearance and outdoor siting.
We develop the heating, hot-water and control strategy around the individual property. Further information is available through our air source heat pump design and installation service.
Older construction, extensions and roof rooms may need different heat-loss assumptions. Insulation and draught improvements can reduce demand, but recommendations should respect the construction and moisture behaviour of the building. The proposed heat pump is then sized for the evidenced fabric rather than an idealised home.
The emitter schedule should show required room output and proposed flow temperature clearly. Each room is checked for required output at the proposed water temperature. This shows which emitters can remain, which may need more surface area and whether pipework or balancing work belongs in the scope.
Trees, boundaries and windows are considered alongside acoustic calculation, drainage and access. Manufacturer sound data, operating conditions, distance, reflections and nearby windows all influence the assessment. Position and model should be checked against the applicable planning and MCS requirements rather than a generic decibel claim.
Consent and installation details should be resolved before ordering equipment for a sensitive property. Heat pumps often perform best with steadier operation and weather-responsive control rather than short, high-temperature boiler bursts. Handover should explain schedules, set points and when manual intervention is actually useful.
For this part of the design, the survey uses property evidence rather than a standard allowance. Some installations can be permitted development when the relevant conditions are satisfied, but listed buildings, flats, conservation considerations and site-specific restrictions may change the route. Position and consent should be checked before ordering. For the Hertford proposal, this is checked against the wider building and heating profile.
Main Service
Professional air source heat pump installation delivering efficient, low-carbon heating and reliable year-round performance solutions.
Potentially. Older construction, extensions and roof rooms may need different heat-loss assumptions. Suitability also depends on emitters, hot-water needs, electrical supply and a workable outdoor position, so a survey and room-by-room design are required.
Yes, correctly selected modern heat pumps are designed to operate in winter conditions. Output and efficiency change with outdoor temperature and water temperature, so the design must use the manufacturer’s performance data at the relevant conditions.
The position needs adequate airflow, service access, drainage and a suitable base, together with an acceptable visual and acoustic relationship to windows, boundaries and outside areas. Pipe distance and protection also influence the choice.
Sometimes. Each radiator should be checked for the room heat loss at the proposed flow temperature. Some may be retained, while others may need more surface area or a different design. Pipework and system balancing also matter.
Eligible property owners may receive Boiler Upgrade Scheme support. The scheme is installer-led and an MCS-certified installer applies on the owner’s behalf. Eligibility and the grant available should be confirmed for the property and technology at the time of application.
The system should be maintained in line with manufacturer and installer guidance. Routine checks can cover the outdoor unit, filters or strainers, system pressure, controls, water quality and recorded performance, depending on the design.
