Positive Input Ventilation

  • Nuaire Positive Input Ventilation

Positive Input Ventilation is a small economical fan with speed settings. These adapt to the size of the house. Plus the number of people who live in the house. This fan then blows a supply of fresh filtered air to your loft space. This is through a small vent placed somewhere in the ceiling of your home. (landing or above the stairs.)

It remove pollutants from the home. It removes surface condensation. It prevents mould growth and reduce house dust mite populations. It gives a home-owner a fresh, healthy and condensation free home.

Heat in your home rises towards the ceiling. This enters the loft as wasted energy. A PIV unit in your loft space can recycle this heat. Couple this with sun rays on your roof’s surface during winter ( solar gain ) and it will warm all the air in the loft to a temperature warmer than that of the outside. This fresh air is then filtered and blown back into your home where it mixes with the rising heat to distribute and mix the heated air inside your home more effectively.
