An air-to-air heat pump takes heat from the outside air and releases it indoors as warm air — the same equipment as reverse-cycle air conditioning, sized and set up for heating.

How we work in West Sussex
Heat loss survey
We assess fabric, glazing and ventilation to size for winter as well as summer.
Design
Units are chosen for their heating output at low outdoor temperatures, not just their cooling rating.
Install
Outdoor units go where defrost water can drain safely and air flow is not restricted. In West Sussex we agree timings around your opening hours.
Set controls
Schedules and set-backs are configured so the system heats efficiently.
Local points to consider
Building fabric
Draughty or poorly insulated premises need more heating capacity; simple draught-proofing can reduce the size needed.
Access and parking
Town-centre jobs in West Sussex often come down to access — loading restrictions, parking for the van and getting equipment onto a roof. We check this at survey and plan deliveries around it.
Defrost water
Outdoor units shed water and ice when they defrost. They need a drained position away from walkways.
Leased premises
If your West Sussex premises are leased, the landlord's written consent is usually needed for external units, wall penetrations and roof access. We provide drawings and data sheets for the request.
Types of premises we cover in West Sussex
- Salons and spas: comfortable salons and treatment rooms despite dryers, lamps and steam.
- Retail and shops: comfortable shop floors, stockrooms and entrances, even with the door open.
Two rules matter for most businesses in England: GB F-gas rules (leak checks from 5 tonnes CO2e) and the periodic energy inspection for more than 12 kW of air conditioning.
