PIV Installation Cardiff, South Wales

How Does Positive Input Ventilation Work?

The PIV unit is installed in the loft area, and a distribution diffuser mounted in the ceiling in the room below. The continual supply and slight positive pressure result in the air in the property being continually diluted, displaced and replaced to create a healthier indoor air quality. 

Is Positive Input Ventilation Worth it?

Damp, mould and condensation can be extremely difficult issues to deal with in a home, and Positive Input Ventilation can greatly help to reduce these, outweighing any of the potential drawbacks of this system. While the price of installing a PIV unit is not extortionate, it’s not insignificant, but compared to constant maintenance issues raised by issues such as damp, it’s a small price to pay on balance. 

 

What are the Advantages of Positive Input Ventilation?

Positive Input Ventilation is a cost-effective solution to a number of problems caused by excessive moisture in the home, including:

  • Condensation on windows
  • Damp and mould
  •  

A PIV unit can also help improve indoor air quality, helping to reduce odours, VOCs and pollutants that enter the house. It can also reduce humidity by ensuring a fresh flow of air into the property. 

PIV is clinically proven to help reduce dust mite allergens which can cause asthma and affect allergy sufferers.

  • How much does the PIV unit cost to run?

    The fan motor typically consumes about 5 Watts of power. Over a year this would cost as little as £7 or less than 2 pence a day.
