How we approach PIV in Clevedon
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.

PIV plus humidity-controlled extract fans in the kitchen and bathroom for the most stubborn condensation.
