How we approach PIV in Louth
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.
Heated PIV
A heater module tempers the incoming air in cold weather. Useful in homes where people feel draughts.
Wall-mounted PIV for flats
Draws air from outside through an outside wall. Suits flats and homes with no loft space.

Rules that apply in England
