Single-room heat recovery units in Somerset

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 Somerset, from Bridgwater, Portishead, Frome, Burnham-on-Sea and Bath. The survey is free for new installations on the UK mainland, and the quote that follows is fixed and in writing.
