Commercial heat recovery units in East Sussex

A commercial heat recovery unit supplies fresh air and extracts stale air through a heat exchanger, so the energy already spent heating or cooling the building is passed to the incoming air instead of being thrown away. It is the standard way to ventilate offices, schools, gyms and clinics efficiently.

We carry out commercial heat recovery units across East Sussex, including Hove, Bexhill-on-Sea, Hailsham, Seaford and Rottingdean. Prices use South East rates. The survey is free for new installations on the UK mainland, and the quote that follows is fixed and in writing.

What commercial heat recovery units involves

Units use plate exchangers (no mixing of air streams) or rotary wheels (higher efficiency, small transfer of moisture). The right choice depends on the use: a gym or swimming area has very different moisture loads to an office. We size units to the building's occupancy and fresh-air needs, plan the duct connections and controls, and commission the system so the design airflows are actually achieved.

Floor or roof units

Larger units for schools, gyms and halls.

Demand control

CO2-led control for variable occupancy.

Replacement of old ventilation

Extract-only systems upgraded to balanced heat recovery.

Plate exchangers keep the air streams completely separate; rotary wheels are usually more efficient and recover some moisture. The use of the space decides which is better.
