What Is Positive Input Ventilation? PIV Units and Systems

Here at I-Sells, as the number 1 supplier of venting and ducting solutions in the UK, we endeavour to bring you the necessity of a properly ventilated home alongside all of the benefits that can be experienced. In this article, we will be answering the question ‘What is positive input ventilation?’

All of the solutions we offer are in an effort to disrupt the environment necessary for mould to formulate, as mould can have serious health implications as well as spread easily if left unattended.

Alongside mould control, our venting and ducting solutions also aid in the removal of condensation, retention (and in some cases addition) of heat, and the removal of stale air in your home.

As we continue, we shall explain exactly what is Positive Input Ventilation (PIV) and its benefits.

So then, what is positive input ventilation? Well, Positive Input Ventilation (PIV) are ventilation systems that provide the most effective method of curing and preventing condensation dampness. Invented by Nuaire and installed in thousands of dwellings each year, PIV can be a more cost-effective and simple to install ventilation solution, whilst still meeting building regulations.

Essentially the concept is to introduce fresh, filtered air into the dwelling at a continuous rate, encouraging the movement of air from inside to outside.

To achieve this, the unit is mounted in the loft space, drawing air through the filters and inputting it, at ceiling level, into the property. An integrated heater tempers airflow should the temperature in the loft space drop below a set point, ensuring ultimate comfort in the home.

The result of this airflow is a reduction in condensation and humidity, a key factor in preventing the cultivation of mould. At I-Sells, one of the PIV units we provide is from the established creator Nuaire, and their product, the Drimaster.

Nuaire’s PIV units are incredibly energy efficient; that’s been a big focus for us ever since we invented this enduring and trusted ventilation strategy half a century ago.

Nuaire’s Drimaster-Eco range takes existing PIV technology a step further, effectively tackling the problem of condensation dampness whilst using up to 20% less energy than other competitors, meaning lower running costs and life cycle costs.

Here are some benefits of a Drimaster:

  • Cures condensation dampness – PIV reduces the humidity in the air, curing condensation dampness and preventing mould growth
  • Improved indoor air quality and healthy living environment- Indoor pollutants from cooking and cleaning, as well as outdoor pollutants including pollen and Radon gas, are eradicated from the home
  • A Unique cost-effective solution
  • Meets Regulations – Meets Part F & L of Building Regulations as a low-energy ventilation strategy
  • Easy & simple installation – Typically installed in under one hour
  • Modern, sleek circular diffuser – Provides occupant acceptability
  • The system controls located in the ceiling diffuser for easy commission and access for maintenance checks
  • Filter change indicator – To ensure optimum performance is maintained
  • Low maintenance – Filter clean or replacement every five years
  • Energy efficient – System goes into standby during warmer months when there is no evidence of condensation
  • Clinically proven to help allergy and asthma sufferers
  • 7-year warranty: 1-year parts and labour, remaining 6 years parts only

Now that we have answered ‘what is positive input ventilation’ let us show you some units. At I-Sells we supply 7 different model types, which we will share with you below.

I-Sells PIV Ventilation range

Nuaire Drimaster Eco Hall Control Diffuser Positive Input Ventilation Unit

The Nuaire Drimaster Eco Hall Control Diffuser Positive Input Ventilation Unit has the added benefit of having the system controls located in the contemporary ceiling diffuser. This unique feature bestows the homeowner with complete control of the unit, without having to enter the loft space.

Not only can settings be altered with the push of a button on the contemporary diffuser, but there is also a 7-segment display which notifies the user of the need for filter change and what setting the Drimaster is running on.

The DRIMASTER-ECO range provides whole-home ventilation using the Positive Input Ventilation principle, which introduces fresh filtered air into the dwelling at a continuous rate, encouraging the movement of air from inside to outside. Click here to view on our site.

Drimaster Eco Heat Positive Input Ventilation Unit With Integral 400W Heater By Nuaire

The Drimaster Eco Heat Positive Input Ventilation Unit incorporates all of the functions of our DRI-ECO-LINK-HC unit but with the benefit of an integrated heating element, located between the flexible duct and ceiling diffuser.

This heating component will temper the air which is distributed through the property via the ceiling diffuser, thus ensuring a comfortable living environment. This pioneering design sees the low-watt heater (400w) react efficiently and effectively, guaranteeing an economically friendly product.

A temperature sensor on the outside of the unit monitors and controls the heater output to maintain the set point. The set point ranges from 5° to 15° and can be adjusted from the ceiling diffuser. If the temperature at the heater outlet is above the set point, the heater will not activate. To browse more details, click here

Nuaire Drimaster Eco 3S Loft Control 3 Storey Property Positive Input Ventilation Unit

The Nuaire Drimaster Eco 3S Loft Control 3 Storey Property Positive Input Ventilation Unit is the only unit within the DRIMASTER-ECO range which is suitable for installation within three-storey properties, by using an intumescent aluminium diffuser in order to meet fire regulation standards.

The unit itself works by drawing fresh air in from the loft space and dispersing it through the property via a powder-coated ceiling diffuser, which provides a 1-hour fire-block. This technology is fundamental to the well-being of the homeowner and allows Nuaire to offer a ventilation solution for every property type. Click here to browse.

This unit also comes with a 7-segment display in the ceiling diffuser, offering complete control at the touch of a button without needing access to the unit located in the loft space. A lock function can be used to ensure the system remains tamper-proof.

Our range of DRIMASTER-ECO units is fitted with an internal temperature sensor. This sensor continuously monitors the temperature in the loft, boosting the air volume when the loft temperature is above a set level.

If the loft temperature becomes excessive the unit will switch to standby mode (no airflow). Once installed, the airflow can be set to suit the house size and, if required, the way it responds to the temperature changes within. To view this product and more information, click here
