Single-room heat recovery units in the Scottish Islands
Through-wall heat recovery for one problem room, without ducting the whole house, across the Scottish Islands.
- From £575 inc VAT per unit
- By arrangement

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.
The Scottish Islands has every kind of building, from old terraces to new estates and business parks, and every job is designed around the building in front of us, not a standard kit.

How we do it
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. They are popular in flats, in north-facing bedrooms where mould keeps coming back, and in rooms with no route for ducting.
Kitchen-diner
A higher-rated unit sized for cooking moisture alongside an extract hood.
Sound-reduced versions
Quieter units for bedrooms.
Single problem room
One unit in the bedroom or kitchen that suffers most.
