Positive Input Ventilation (PIV) Installation in Liverpool

Positive Input Ventilation (PIV) is a system designed to improve indoor air quality by introducing fresh, filtered air into a home. This is particularly useful in properties where humidity, condensation, or poor ventilation may lead to damp, mould, or stale air.

Here are the key benefits of using PIV in your Liverpool home:

Improves Air Quality

PIV brings fresh, filtered air from outside into the home, reducing indoor air pollutants like dust, allergens, and volatile organic compounds (VOCs). It dilutes contaminants and keeps air circulating, which is especially important in homes with poor ventilation.

Reduces Condensation and Damp

By continually circulating fresh air, PIV helps balance humidity levels. This reduces condensation on windows and walls, which can help prevent the growth of mould and damp patches. Damp is often a key factor in respiratory issues and home damage.

Prevents Mould Growth

Mould thrives in damp, humid environments, often caused by condensation. By keeping air moving and reducing moisture levels, PIV inhibits mould growth, leading to a healthier living environment and reducing property maintenance costs.

Improved Comfort

Continuous air circulation creates a more comfortable indoor climate. It helps avoid stuffiness and stale odours, keeping the air feeling fresh and clean throughout your Liverpool home.

Installing a Positive Input Ventilation (PIV) System

Installing a Positive Input Ventilation (PIV) system couldn't be easier, it typically involves:

1. Assessing the Property

Initial Survey: Before installation, we will assess the home to determine the most suitable PIV unit based on the size of the property, its layout, and any existing ventilation issues (e.g., condensation, damp).
Location Selection: The ideal location for the unit is typically in the loft (for houses) or on the ceiling of a hallway or central space (for flats/apartments). This allows the PIV unit to draw in fresh air from outside or from the loft area and distribute it evenly throughout the home.

2. Installing the PIV Unit

Loft Installation (Houses): In houses, the PIV unit is often installed in the loft space. It draws in fresh air from the loft or directly from outside via an air vent.
Mounting the Unit: The unit is usually suspended from the roof joists or placed on a suitable surface in the loft.
Connecting the Ducting: A duct connects the PIV unit to a diffuser, which will be located in the ceiling of a central location like the hallway. The diffuser is where the fresh air is delivered into the home.
Electrical Connection: We usually make all the electrical connections within the loft so no unsightly cabling.
Switches Installed: We will install the switches to control your new PIV system at a convenient location
