PIV - Positive Input Ventilation Unit (Loft)

Loft Ventilation Unit

With 58% of homes suffering from mould and condensation, good ventilation is not just good for your home but for your health as well.

Moisture in the air is the root cause of mould and condensation and Positive Input Ventilation is the energy efficient method of resolving the issue. With a Loft Ventilation Unit you can replace the stale, unhealthy air with drier, fresher air circulating the property.

Fitted in the roof void and ducted via a circular air diffuser mounted in the ceiling above a stairwell. All units are fitted with a preheat facility and the heater is activated automatically when the incoming air drops below the pre-selected set point. This can be manually changed to between 5 to 20°c to suit your requirements.

As a positive input ventilation system, it works by introducing fresh, filtered air into your home at a continuous rate, encouraging the movement of air from inside to outside the property. The PIV unit is mounted in the loft where it draws air through specially-designed filters before inputting into your home at ceiling level. The filters remove pollutants such as Radon gas, pollen, and traffic fumes delivering better indoor air quality. Overall this makes for a healthier living environment, in particular for allergy sufferers and those with asthma.
