What is Positive Input Ventilation?
Drimaster PIV units are installed in over a million homes in the UK
- cost-effective solution to damp and mould
- fast install (can be installed in a loft in less than an hour)
- longevity (20+ years)
- non-disruptive nature for residents
How does Positive Input Ventilation work?
PIV works by drawing fresh air in through the unit that’s usually, but not always, installed in your loft. This air is then filtered and gently diffused at ceiling level, creating a positive pressure within the home that forces air pollutants out through the natural leakage gaps found in every UK property, both old and new.
When would you recommend using a PIV unit?
Positive input ventilation is a highly trusted, cost-effective, and simple solution to ensure clean air flows freely throughout your home, making poor indoor air quality a thing of the past. PIV units are used for a few different reasons, including the displacement of indoor pollutants, including stagnant and humid air. The installation of PIV units is generally recommended if you’re not looking to carry out a full renovation of your home yet require ventilation throughout the dwelling without removing any walls.
Does a PIV unit cure damp and condensation?
Condensation is a fast-growing problem: it’s estimated that one in five houses in the UK is poorly ventilated and at risk of streaming windows, mould growth and poor indoor air quality. The average family produces up to 10 litres of water daily through simple everyday tasks such as cooking, washing, bathing and drying clothes indoors.
New and modern homes are at risk of condensation: poorly heated homes are prone to condensation dampness. In contrast, well-insulated homes with double glazing or insulation can trap moist air inside the house. When it comes to curing damp and condensation, PIV is the most cost-effective whole home system in the market today: that’s why it’s trusted by so many homeowners and landlords across the UK.
How energy efficient are Nuaire’s PIV units?
Our PIV technology and product range has continually evolved since the first iteration in 1972. The introduction of Drimaster-Eco saw the unit using up to 20% less energy.
Now, Drimaster has evolved once more!
Our latest Drimaster-Eco PIV unit has become a more sustainable unit as a result of swapping the casing from a virgin ABS plastic to 100% recycled plastic. The switch will result in a reduction of 167 tons of equivalent embodied carbon over the period of a year. Embodied carbon is the emissions associated with the production, transportation, installation, and disposal of a product.
Embodied carbon is the emissions associated with the production, transportation, installation, and disposal of a product. Did you now mechanical, electrical, and plumbing (MEP) systems are estimated to account for around 23% of a building’s embodied carbon?
