Through-wall heat recovery for one problem room, without ducting the whole house, across Cambridgeshire.
- 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.
