Learn about Positive Input Ventilation.

  • It works by gently introducing fresh, filtered air into the dwelling. Air is drawn into the unit and is passed through filters before being pushed around the home – as the air moves, it creates a pressure as it dilutes, displaces and eventually replaces the stale air in the home.

    As air is constantly moving, humid air cannot settle on cold surfaces, such as windows or outer walls, meaning it cannot condensate. Eventually, this humid air is forced out of natural leakage points throughout the home – such as windows, under doors or even through keyholes.

    We installed our very first PIV unit in a bungalow in Sheringham on the North Norfolk Coast in 1981.

  • We recommend that your PIV system be installed by a trained professional. All installers at Dovedale Dampcure Services Ltd are not only qualified electricians, but crucially, are also experts in dampness and ventilation.

  • Nuaire provide a 7 year warranty on this product with the first 12 months part and labour. Dovedale, however, bolster the already great Nuaire warranty by covering the remaining 6 years with labour giving you a 7 year parts and labour warranty.
