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.
Clwyd has every kind of building, from old terraces to new estates and business parks, and every job is designed around the building in front of us, not a standard kit.

How we do it
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.
Replacement of old ventilation
Extract-only systems upgraded to balanced heat recovery.
Ceiling-void units
Compact horizontal units for offices and shops.
Floor or roof units
Larger units for schools, gyms and halls.

In Wales, the Welsh Government's own Approved Document F (2022 edition) applies to ventilation in homes, with a new edition taking effect on 4 March 2027. Rented homes must be fit for human habitation under the Renting Homes (Wales) Act 2016, and workplaces must be ventilated under the Workplace (Health, Safety and Welfare) Regulations 1992.
How much does a commercial heat recovery unit cost?
A commercial heat recovery unit typically costs £6,950 to £24,950 excluding VAT supplied, installed and commissioned, depending on airflow, unit type and access.
Plate or rotary heat exchanger?
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.
