Single-room heat recovery units in Derbyshire

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.
