Single-room heat recovery units in Bristol
Through-wall heat recovery for one problem room, without ducting the whole house, across Bristol.
- From £625 inc VAT per unit
- Free survey
A single-room heat recovery unit is a compact through-wall fan that supplies and extracts air for one room while recovering much of the heat from the outgoing air. It is the answer when one bedroom, kitchen or flat has a condensation problem but whole-home ducting is not practical.
Across Bristol the job is priced the same way wherever you are: what is fitted, how long it takes and how far we travel. Towns we cover include Bristol.

Questions about single-room heat recovery units in Bristol
Is the survey free in Bristol?
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.
Can one unit do a whole flat?
One unit treats one room well. For a whole flat, two paired units or a wall-mounted PIV unit with good extract fans is usually better.
Do they need servicing?
Filters need a clean every few months and occasional replacement, which most owners do themselves.
Which rules apply to ventilation in Bristol?
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.
