PIV for Stornoway homes
Many units have a temperature sensor that reduces the flow or switches to a heater module on cold days, so the incoming air does not feel like a draught. Flats without a loft use a wall-mounted unit that draws air from outside through a cored hole.
Wall-mounted PIV for flats
Draws air from outside through an outside wall. Suits flats and homes with no loft space.

Questions from Stornoway
Do you cover Stornoway and nearby?
Yes. We cover Stornoway and the surrounding area. Send your postcode and we will confirm.
How much does PIV cost to run?
A standard PIV unit uses very little electricity, comparable to a low-energy light bulb on normal speed. A heated unit costs more in cold spells because the heater switches on when loft air is cold.
Will PIV make my house cold?
Most units temper or reduce the flow when the incoming air is cold, and a heated unit warms it. Placed correctly on the landing, the air spreads gently rather than blowing on anyone.
What is the price of a PIV unit in Stornoway?

We will check the existing fans in your Stornoway home at the same visit, because PIV works best with them working.
