Single-room heat recovery units in Hampshire

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.

Every job in Hampshire gets a written quote before it starts and a commissioning record when it finishes. We cover Gosport, Waterlooville, Farnborough, Eastleigh and Winchester and the villages around them.
