What is a PIV unit and how does it work?

19th August 2017

A PIV unit has multiple benefits to your living environment.

Lately, we have had a lot of questions asking what is a PIV unit?

PIV stands for Positive Input Ventilation. A PIV unit is a system that is able to pump fresh air in to your living environment. While at the same time forcing out the old stale air that is accumulating and causing condensation. In turn, building up damp which can then cause mould and allergens from the spores.

Take the Nuaire DriMaster as an example, a ventilation unit is inserted into the loft floor. It then extracts fresh air from the natural areas in the loft where air would seep in. As this passes through the Nuaire Drimaster’s fan it is pushed through a filter. Then automatically pumped into the home, Circumventing this new fresh air that is then pushing out the old and possibly harmful air.

The purpose of this system is to first and foremost create a better breathing environment around the entire home. Which means that allergens in the air that could trigger respiratory problems like asthma can be dramatically reduced.

To demonstrate it’s purpose as more than just an anti-mould item. Imagine living near factories or even a busy road. One would expect to have more polluted air than most so you could expect the Nuaire Drimaster to significantly improve the air you breathe in the home.

Energy Saving Benefits

The nature of a PIV unit is to keep air circulating. As far as warm air is concerned your central heating is less likely to escape while it’s in circulation.

With a PIV unit in place, opening windows for those cold mornings where your windows are streaming should be a thing of the past. You no longer have to consider whether you open the windows and let the heat escape or leave them closed and watch moisture build up.
