Commercial heat recovery units in Gwynedd and Anglesey
Plate and rotary heat recovery units that cut the cost of fresh air, across Gwynedd and Anglesey.
- From £6,600 + 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.
Our team is based in Great Barr, Birmingham, and we work throughout Gwynedd and Anglesey, from Bangor and Holyhead. 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.
Demand control
CO2-led control for variable occupancy.
Replacement of old ventilation
Extract-only systems upgraded to balanced heat recovery.
Ceiling-void units
Compact horizontal units for offices and shops.
