What is positive input ventilation
Positive Input Ventilation (PIV)
Positive Input Ventilation (PIV)
Positive Input Ventilation (PIV)
Developed in 1972 by Nuaire as a process of ventilating existing homes, by circulating and pumping fresh air that has been filtered into the house. Thus creating a healthy environment by removing stale air from the building
How does it work?
Positive Input Ventilation (PIV)
Positive Input Ventilation (PIV)
The unit which is generally installed in the loft, depending on type required, draws in fresh air, which it then filters. This air is then pushed out at ceiling level to create a positive pressure. This pressure then acts upon any pollutants forcing them out through gaps in the natural leakage points which are in every property within the UK, whether new or old.

The PIV might not be suitable if you have little or no loft space, although it should be noted that wall hanging units are also available.
The main disadvantage is that as the unit is in the loft, during summer it is likely to draw in hot air and cold air in the winter.
