Intelligent Positive Input Ventilation or I-PIV

The latest and most effective method of dealing with condensation is a whole house Intelligent Positive Input Ventilation unit (I-PIV).


What is I-PIV?


An I-PIV is a method of removing the moist air that is causing your damp problem. It does this by taking dry air from your attic, roof space or loft, which is then mixed with the moist air, and then pushed out of the building through window and door vents, and air bricks. This improves the air quality, and circulation air is pushed through the building.


The units are "intelligent" and know to warm the air slightly during the winter, but not during the summer.


I-PIV's also contain filters, so they also remove impurities such as pollen dust and mites from the air in your home, bringing relief to Hay-Fever and Asthma sufferers and to those with other health conditions which affect their breathing.

The effect is immediate, and works all through the house, not just in the kitchen or bathroom where you will commonly find condensation.


There are several models available, all of which are quiet and discreet, and we will be able to advise which will best suit your home. We even have a version for flats that don't have a loft/attic.

The units use very little electricity, costing around £25 per year to run, 24 hours a day, 365 days a year!
