How we approach PIV in Deeside
It does not replace extract fans: kitchens and bathrooms still need their own extract to remove steam at source. On survey we check the loft, the landing position and the existing fans, and we tell you if PIV is not the right answer.
Loft-mounted PIV
The most common option for houses with a loft. Usually fitted in half a day.
Heated PIV
A heater module tempers the incoming air in cold weather. Useful in homes where people feel draughts.
