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).

These work by taking dry air from the attic, roof space or loft, and mixing it with the moist air within the house. This has the effect of diffusing the moisture content in the air, improving air quality and circulation, as it pushes moist air out of the building.

The units are "intelligent" as they sense that the air doesn't need warming during the summer, but heats it slightly in winter. So on hot days, they will not push hot air into the home.

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

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.

I-PIV's can help in the battle to stop the spread of coronavirus.

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!
