PIV Unit installation should always be carried out by a professional electrician and specially trained ventilation installer. An unqualified person will be in breach of the building and electrical regulations which may invalidate your household insurance. If the unit is not fitted in the correct location or by an approved installer, it will not function at its optimum performance and may also invalidate the manufactures guarantee.

We have been involved in installing PIV Units for over 10 years and we can explain to you simplify how we are resolving your condensation and mould growth problems just by installing one of our PIV units.

They will improve your indoor air quality immediately and with a low daily cost to run, next to zero noise, no water to empty and no taking up of floor space, they will reduce the humidity levels in your home and provide additional health benefits as well!

What is a PIV Unit?

Positive Input Ventilation Units (PIV) ventilate the whole house and create a fresh and healthy living environment by supplying fresh, filtered air into a property at a continuous rate.

They are mainly used to control indoor air quality by diluting and displacing indoor pollutants. They can also be used for thermal comfort or dehumidification purposes.

The gentle flow of clean and filtered air inside the home makes no noise so is unnoticeable but powerful enough to raise the overall air pressure inside your home. This process ensures that the damp, stale air is forced out of your house through any vents and gaps.

Normally, the PIV unit is installed in your loft or just above the stairs. Because heat rises, it is important to put the PIV unit at ceiling height so that the loft space (or area above the stairs with wasted air space) captures the maximum amount of air to recycle for maximum energy efficiency.

How does a PIV Unit work?

Positive Input Ventilation or PIV Units work by intentionally encouraging and blowing clean filtered air into your home via a filter (which is stored inside the unit) which in turn, raises the air pressure within your house.

The PIV unit reduces and eliminates surface condensation altogether by gently forcing out humid stagnant air with fresh filtered air. The moisture will start to leave the property through leakage points such as air vents, trickle vents, keyholes, letterboxes (basically anywhere a draught comes in).

As all this is happening, the heat of the sun during winter months means the fresh air will be warmed naturally which saves you and your household money whilst it is being filtered into your home.

The PIV unit has different levels depending on how severe your situation is and what is needed.

Frequently Asked Questions

When our PIV unit is operating at a normal speed, you can barely hear it and are designed to be practically inaudible whilst always ensuring the best level of whole house air ventilation is maintained.

If you turn up the setting to manage higher air moisture for a short period, the noise will slightly increase but once this humid air has been displaced, the unit will reset to its normal lower levels and this slight noise will disappear.

The PIV generates air that will be colder than inside your house, but as the inside of your loft is warmer than outdoor air (due to solar gain and heat rising through your ceilings), it means you will not feel the cold air.

We do offer heated PIV units that thermostatically pre-heat the air to a setting of your choice but as the cool air at low speeds is so unnoticeable, it does not always make economic sense to power a heating element inside the PIV.

On hot days, the PIV sensors switch the unit off and automatically switch the unit back to the air filtration setting once the temperature lowers in the evening.

PIV units have extremely low upfront costs considering its capabilities.

They have minimal energy usage consuming on average 5 watts of power which works out at approximately 1 pence to 3 pence a day to run. There are potential cost savings to be made on your heating bills and therefore PIV systems have long been considered as one of the most affordable ways to provide whole home ventilation.

The simple answer to this is NO. As soon as the unit is installed, it will monitor the temperature and the air itself without your help. The PIV unit is set to optimise air quality and energy itself.
