Single-room heat recovery units in Dyfed
Through-wall heat recovery for one problem room, without ducting the whole house, across Dyfed.
- From £575 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.
Our team is based in Great Barr, Birmingham, and we work throughout Dyfed, from Haverfordwest, Milford Haven, Llanelli, Ammanford and Aberystwyth. Surveys for new installations are free on the UK mainland, with a written quote afterwards.

What the work 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.
Paired units in a flat
Two alternating units working together across living spaces.
Kitchen-diner
A higher-rated unit sized for cooking moisture alongside an extract hood.
Sound-reduced versions
Quieter units for bedrooms.

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