Positive Input Ventilation

What is Positive Input Ventilation

­

The air that we breathe inside our homes is important to our health and provides a comfortable living environment. It may come as a surprise but the average daily moisture production within a home from everyday activities such as cooking and bathing is typically around 5-10 litres.

 

As we spruce up our homes by furnishing and cleaning them we also introduce a concoction of other contaminants into the air inside the home. These include chemicals from cleaning products and formaldehydes from carpets and furniture.

 

As energy costs continue to rise, we strive to save money and energy by improving our homes and invest in installing double glazing, cavity wall and loft insulation. By doing this, we prevent ‘natural ventilation’ which means that the moisture we produce along with the stale, polluted air has no means of escape. This causes condensation on windows, which left untreated will lead to black mould and musty odours.

 

The concept of Positive Input Ventilation (PIV) is to essentially introduce fresh, filtered air into the home at a continuous rate, encouraging movement of air from inside to outside. A property installed unit will ensure that old, contaminated and moisture-laden air in your home is continuously diluted, displaced and replaced with good quality, fresh air. The result is an environment in which condensation dampness cannot exist, and where allergens and pollutants are kept to a minimum – an added benefit for asthma and allergy sufferers who could see a significant improvement to their symptoms.

Single Room Extract Fans

PIV Ranges are quick, cost-effective and easy to install, making them an ideal solution

1. CLEAN FRESH AIR - Is continuously drawn into the loft space through the lofts natural leakage points.

 

2. THE AIR THEN RISES - to the highest point, gaining heat energy giving you the benefit of some heat recovery.

 

3. THE AIR IS THEN PASSED - through the filters and is gently fed into the dwelling via a central hallway diffuser.

 

4. THE AIR THEN - gently pressurises the house from inside out, driving out moisture and condensation.

 

5. THE PROCESS CREATES - a clean, healthy environment to live in as fresh air replaces the stale air.
