What the work involves
Flats without a loft use a wall-mounted unit that draws air from outside through a cored hole. PIV works well in houses and flats with general condensation on windows and cold walls.
PIV with fan upgrades
PIV plus humidity-controlled extract fans in the kitchen and bathroom for the most stubborn condensation.
Loft-mounted PIV
The most common option for houses with a loft. Usually fitted in half a day.
