Commercial heat recovery units in Surrey

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.

Surrey 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.

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.

Floor or roof units

Larger units for schools, gyms and halls.

Demand control

CO2-led control for variable occupancy.

Replacement of old ventilation

Extract-only systems upgraded to balanced heat recovery.

Questions about commercial heat recovery units in Surrey

Is the survey free in Surrey?

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.

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.

How noisy are they?

Units are fitted with attenuators where needed so noise in occupied rooms stays at acceptable levels.

Which rules apply to ventilation in Surrey?

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.
