PIV Units

Positive input ventilation (PIV) is a popular and energy efficient whole home ventilation solution. PIV units provide a long-term solution to poor indoor air quality and associated problems such as condensation, damp and mould growth which can lead to timber and decoration damage and potential health concerns for residents.

PIV units can be installed either in the loft or on an internal wall to introduce a source of clean, fresh air into the home to keep your property fresh and dry.

In short Positive Input Ventilation (PIV) pushes out and replaces moisture laden air with drier fresh air by introducing filtered air from outside into the property and increasing air circulation thereby improving the indoor air quality.

Effective ventilation of moist air prevents condensation and mould within the home by removing the moisture and other pollutants from the air. Fixing the problem at the source in a way that simply wiping away condensation or cleaning and painting over mould will not.

PIV works by drawing fresh air in through the positive input ventilation unit that is usually installed in the loft though wall mounted options are available for flats and apartments. The air drawn in by this unit is filtered and introduced to the property, in turn displacing moist air that leads to condensation.

The installation of positive input ventilation is generally recommended if you require ventilation throughout a property but are not in a position to remove any walls or perform any other sort of major renovations.

For this reason PIV units are a popular choice for properties that have inadequate ventilation in bathrooms and kitchens when rebuilding these rooms is not an option.

Yes, with condensation becoming a bigger problem than ever, particularly in the rental sector, where landlords and housing providers are under increased pressure to improve the air quality of their properties. It is estimated that up to 20% of all homes in the UK are poorly ventilated and at risk of condensation, damp, black mould growth and low air quality.

When you consider that the average family introduces litres of water into the air in their home through everyday tasks such as cooking, showering or washing and drying clothes, it is no wonder that so many properties need extra ventilation to fight damp living conditions.

When it comes to preventing condensation and mould, positive input ventilation is simply one of the best and most cost-effective solutions available.

Regardless of the type of property you live in, whether it is a bungalow or multi storey flat, Peter Cox have units designed to ventilate your house properly to tackle any condensation problems.

Loft Mounted Unit - Taking advantage of the benefits of solar gain in the loft space, this is the ventilation unit of choice if you have a loft or roof void space. It is ideally situated and is well hidden away. Fresh air is drawn from the operating position in the loft, and delivered to the rest of the property. The unit contains an integral pre-heater for use in periods of low external temperature.

Wall Mounted Unit - Designed for use in the hallway or landing of a flat, this unit uses the same low watt motor technology as the loft mounted unit. Fresh air is drawn into the home and mixes with the warm air that accumulates at ceiling level, re-distributing heat around the rooms and forcing moisture-laden air out of the property.
