Single-room heat recovery units in East Sussex

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.

We carry out single-room heat recovery units across East Sussex, including Hailsham, Seaford, Rottingdean, Brighton and Eastbourne. Prices use South East rates. We survey first, free of charge for new installations on the mainland, then send a fixed written quote.

How we do it

Units fit into a cored hole in an outside wall. 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.
