If you are struggling with mould and condensation then a PIV system may be the solution you need.

These PIV systems are loved by social housing providers because they just work. Once installed they do not need any adjustment and will quietly work to keep condensation away.

Positive Input Ventilation (PIV) systems offer several benefits for improving indoor air quality and reducing issues like damp and mould. Here are some key reasons to use a PIV system:

  1. Reduced Condensation and Damp: PIV systems help to eliminate surface condensation by introducing fresh, filtered air into your home, which replaces the humid, moist air that can lead to damp and mould.
  2. Improved Air Quality: By continuously supplying fresh air and expelling stale air, PIV systems improve indoor air quality. This can reduce indoor pollutants like carbon dioxide and allergens.
  3. Energy Efficiency: PIV systems are energy-efficient, often more so than other ventilation systems. They gently introduce filtered air into the home, which helps to maintain a comfortable indoor environment without significant energy consumption.
  4. Easy Maintenance: PIV units are generally installed out of the way in the loft, and require minimal maintenance. They operate continuously, ensuring a consistent flow of fresh air.
  5. Health Benefits: By reducing damp and mould, PIV systems can help prevent respiratory issues and allergies, contributing to a healthier living environment
