Positive Input Ventilation

Banish condensation and mould with Positive Input Ventilation (PIV). It’s the most effective way of curing and preventing condensation, dampness and mould. Installed in over one million homes, PIV is the UK’s most popular method of low-energy, whole-home ventilation.

What causes condensation and mould?

Before the days of double glazing and loft and cavity wall insulation, humid, stale air would escape through ill-fitting windows, doors and lofts. And would be replaced by fresher, colder air.

But with the introduction of energy-saving insulation measures, there is no natural escape route for the moist air caused by our daily routines of showers, boiling kettles, cooking and drying clothes.

And simply breathing. A family of four will produce approximately four pints of water per person every day. That’s over 100 pints of water vapour a week, which has nowhere to go. It’s now trapped inside the home. The result is condensation and mould on windows and walls. Along with poor air quality.

Unfortunately, if you have damp and mould in your home, you’re more likely to have respiratory problems, allergies or asthma. Damp and mould can also affect the immune system.

Why do you only install Nuaire PIV Units ?

Invented by Nuaire in 1972, the technology is now installed in over a million homes. It’s tried and tested technology.

PIV is trusted by social housing providers, new build developers, private landlords and homeowners alike.
It is a cost-effective, whole-house ventilation system designed to provide a healthy living environment in your home.

Nuaire’s PIV units are incredibly energy efficient; that’s been a big focus for us ever since we started installing such devices

The Drimaster-Eco range takes existing PIV technology a step further, effectively tackling the problem of condensation dampness whilst using up to 20% less energy than other brands on the market, meaning lower running costs and life cycle costs.
