Commercial heat recovery units in Norfolk

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.

Across Norfolk the job is priced the same way wherever you are: what is fitted, how long it takes and how far we travel. Towns we cover include Bowthorpe, East Dereham, North Walsham, Downham Market and Norwich.

What the work 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.
