Single-room heat recovery units in Cheshire

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.

What single-room heat recovery units involves

Some alternate direction every minute or so, storing heat in a ceramic core; others run supply and extract side by side through a small exchanger. Either way, the room gets fresh air without the heat loss of an open window. They are popular in flats, in north-facing bedrooms where mould keeps coming back, and in rooms with no route for ducting.

Rules in England

In England, ventilation is covered by Part F of the Building Regulations and its guidance, Approved Document F (2021 edition). For homes, it sets minimum extract rates such as 15 litres a second for a bathroom and 30 or 60 for a kitchen, and expects mechanical systems to be airflow-tested.

Questions about single-room heat recovery units in Cheshire

Is the survey free in Cheshire?

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.

How noisy are they?

On low speed most units are quiet enough for bedrooms; sound-reduced models are available. Boost speed is more noticeable.

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.

Which rules apply to ventilation in Cheshire?

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.
