Nuaire Drimaster Eco Heat HCS (PIV)

The Nuaire Drimaster Eco Heat HCS (PIV) provides whole home ventilation using the Positive Input Ventilation (PIV) principle. Essentially the concept is to introduce fresh, filtered air into the dwelling at a continuous rate, encouraging movement of air from inside to outside. 

To achieve this, the PIV 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.

How does a PIV work in my home?

Nuaire PIV How Does It Work

Works by gently introducing fresh, filtered air into the dwelling. Air is drawn into the unit and is passed through filters before being pushed around the home

As the air moves, it creates a pressure as it dilutes, displaces and eventually replaces the stale air in the home.

As air is constantly moving, humid air cannot settle on cold surfaces, such as windows or outer walls, meaning it cannot condensate.

Eventually, this humid air is forced out of natural leakage points throughout the home – such as windows, under doors or even through keyholes.

Which Naurie PIV is best for me?

Be condensation smart

  • 1-5 UK households are homes are poorly ventilated.
  • Do you dry clothes inside your home on the radiator
  • Insulated home also traps the moisture and will not release it?
  • Do you have excess moisture condensing on windows & walls?
  • Bad air house air flow, blocked sealed up air bricks

We have the answers

  • Do you have streaming water on your windows?
  • Do you have mould growth?
  • Do you have poor indoor air quality?
  • Do you have excess moisture condensing on windows & walls?
  • The average UK family produces 10 litres of water a day
  • Is your home correctly heated?

  1. Josh

    Really good piece of kit and best price I could find online and next day delivery for free

    Cheers guys

  2. Jason

    I had really bad condensation throughout my house, I spoke to Paul and he advised me to buy a PIV within 24 hours the problem was solved.

  3. Faisal saleem (verified owner)

    Also had a condensation problem with black mould in my bedroom. After a lot of research and YouTube videos decided to buy this unit and glad I did. After only a few hours I notice on my humidity sensor that the moisture in the air was dropping and after about a day it seems to have stabilised. One thing to note though is even though I have the heated version, the amount of cold weather we have at the moment means the heating is on more often but for me that is far better than the increasing amount of black mould and damage that the condensation was causing.
