Positive Input Ventilation (PIV) is the most effective method of curing and preventing condensation dampness. 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 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.
We have 9 different model types, starting with our basic model below that have been designed for occupant preference and house type.

Basic model with controls sited on the unit within the loft. The unit 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 (heat recovery mode). 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.
The unit comes with a 5 year warranty: 1 year parts and labour, remaining 4 years parts only (UK and Ireland only).

I just wanted to thank you for your excellent product, the Drimaster-Eco. My bungalow has suffered from condensation since it was new in 1984. Wet windows, peeling wall paper, black mold. You name it, we've had it!! A few months ago, I heard about your products and to be I honest I was skeptical to say the least. However, I did some research the results of which were all extremely positive so I "bit the bullet" and purchased the Drimaster-Eco. The results have been remarkable!!! No more wet windows, no more black mold. Fantastic!!. Thank you!! I only wish Id heard about you sooner. I will continue to recommend your product as I have done to two neighbours and others recently.
This really works. We suffered condensation & damp for 20 years before we installed a Nuaire Drimaster unit. It's been fitted now for 5 years & after the first 3 weeks we haven't suffered condensation or damp since. Thanks Nuaire
Just wanted to say what an amazing difference fitting your Drimaster PIV units has made to our house. Read about these units on the internet after researching how to deal with black mould and condensation on our windows. We’ve lived in our double glazed, cavity filled bungalow for 4 years and despair at the mould that appears every autumnal and winter. I found it hard to believe that such a simple solution would resolve the problem. I can’t believe the difference in condensation in less than 24 hours.
Absolutely delighted with our new DRI-ECO-HC ventilation system. Worked straight away, no condensation in wardrobes and walls dry. Struggled for 2 years trying to solve this problem.
