Commercial heat recovery units in Gwent

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 Gwent, including Blackwood, Newport, Cwmbran, Pontypool and Ebbw Vale. Prices use Wales rates. We survey first, free of charge for new installations on the mainland, then send a fixed written quote.

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.

Questions about commercial heat recovery units in Gwent

Is the survey free in Gwent?

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.

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.

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.

Which rules apply to ventilation in Gwent?

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.
