PIV for Lancing homes
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.
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.
