Commercial ventilation, Cornwall
Commercial heat recovery units in Cornwall
Plate and rotary heat recovery units that cut the cost of fresh air, across Cornwall.
- From £7,250 + VAT per unit
- Free survey
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 Cornwall, including Camborne, Newquay, Penzance, Bodmin and Redruth. Prices use South West rates. Surveys for new installations are free on the UK mainland, with a written quote afterwards.

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.
Ceiling-void units
Compact horizontal units for offices and shops.
Floor or roof units
Larger units for schools, gyms and halls.
Demand control
CO2-led control for variable occupancy.

For new installations on the UK mainland, yes. The survey is free and the quote that follows is fixed and in writing. Servicing, testing and repair visits are charged, and we confirm the cost before booking.
Can heat recovery be added to an existing system?
Sometimes. Extract-only systems can often be upgraded to balanced supply and extract with a heat recovery unit.
Will it reduce heating bills?
Recovering heat from extract air usually reduces the heating needed for fresh air, especially in busy buildings with long operating hours.
