Positive Input Ventilation (PIV) systems create fresh and healthy living environments by supplying fresh, filtered air into a property at a continuous rate throughout a property and is our most popular method of whole house ventilation.
Energy recovery ventilation systems provide a controlled way of ventilating a home while minimising energy loss. They reduce the costs of heating ventilated air in the winter by transferring heat from the warm inside exhaust air to the fresh (but cold) outside supply air.
Positive Input Ventilation (PIV) is a whole house air ventilation system that works by drawing in fresh, filtered air into a property from outside. These can be either installed in a loft space or on a wall in a flat or apartment. They ensure that a continuous supply of air is supplied into the home to eliminate or significantly reduce condensation.
Ventilation is the intentional introduction of outdoor air into a space and is mainly used to control indoor air quality by diluting and displacing indoor pollutants; it can also be used for purposes of thermal comfort or dehumidification.

All of our PIV units are designed to perform with extremely low noise levels, always ensuring the best level of whole house air ventilation is maintained.
Positive Input Ventilation is a whole-house form of air ventilation which is designed to supply fresh air to the whole property. In some cases, where there is a remote wet room (kitchen, ensuite, bathroom, WC or utility room) we also advise fitting extractor fans.
The units are either situated in the loft in a house, or on a wall in an apartment to deliver whole house ventilation. They operate quietly in the background, eliminating condensation and preventing mould whilst maintaining healthy indoor air. All of our PIV units are fitted with an ultra-low watt motor to ensure minimum energy consumption.
Did you know that 95% of our customers experience an improvement in condensation within one week after having a unit fitted?
