Home ventilation, Norfolk
Single-room heat recovery units in Norfolk
Through-wall heat recovery for one problem room, without ducting the whole house, across Norfolk.
- 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.
Across Norfolk the job is priced the same way wherever you are: what is fitted, how long it takes and how far we travel. Towns we cover include North Walsham, Downham Market, Norwich, Great Yarmouth and King's Lynn.

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.
