The Flatmaster FLAT2000L no loft PIV unit provides whole home ventilation as well as offering the most effective method of curing and preventing mould & condensation dampness.

Nuaires PIV units provide a continuous supply of fresh air. They filter air into the home to create a healthy environment, whilst helping to eradicate allergens, pollutants and even harmful gases.

Do PIV units stop condensation?

Positive Input Ventilation (PIV) units are the most effective method of curing and preventing condensation dampness.

Does a PIV unit make the house cold?

The simple answer is no but it depends on the model of PIV unit you install. Many PIV systems include a heating element to warm the air before introducing it into the property.

How much does it cost to run a Drimaster PIV unit?

Nuaire estimates the running cost around 5-10p per day.  This is depending on electrical supplier and speed setting and how frequently the heating element is activated.
