Commercial ventilation, Dorset
Commercial heat recovery units in Dorset
Plate and rotary heat recovery units that cut the cost of fresh air, across Dorset.
- 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.
Our team is based in Great Barr, Birmingham, and we work throughout Dorset, from Canford Heath, Bournemouth, Poole, Weymouth and Christchurch. 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.

Questions about commercial heat recovery units in Dorset
Which rules apply to ventilation in Dorset?
In England, ventilation in new and altered homes is covered by Approved Document F of the Building Regulations. Landlords also have duties under the Housing Health and Safety Rating System, and workplaces must be ventilated under the Workplace (Health, Safety and Welfare) Regulations 1992.
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.

Recovering heat from extract air usually reduces the heating needed for fresh air, especially in busy buildings with long operating hours.
