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

Fantastic, easy to install, quite and doesn't look bad and blends in well. Condensation gone in days, mould disappearing a must have for a clean and healthy lifestyle.

This is a game changer difference is huge I used one unit to supply air in the three rooms air quality is great no condensation !!!

We live in a 200 year old listed building. The cost to replace the windows (single sash) would be astronomical. Every morning in the winter I had to use a Karcher Window Vac to remove the water from all the steamed up windows . I came across this PIV on YouTube and was sceptical to say the least. I bought it anyway. The unit is huge but not heavy , just bulky . I installed it in about an hour . The next morning when I got up every window in the house was crystal clear. I'm absolutely amazed and dumbstruck how this PIV unit works. If your house suffers from damp/moisture I highly recommend getting this unit. I live in the far north of Scotland so bought the one with the heater but not sure about the difference between using the non heater version .

Only given 4 stars as not yet installed unit. Very good service. Hopefully it will cure the problem as PIV unit is recommended for air changes 24/7. Installation looks straight forward. For information the vent hose is 2 meters long, could find this out before hand.

We had wet walls and black mould, a camera test revealed missing cavity wall insulation causing cold spots. Rather than pay thousands to have the insulation removed we decided to by the drimaster piv. We were sceptical, but after 4/5weeks of use we have no damp walls and mould has not returned. So pleased best £500 spent, it really works. We bought the heated version, which cost approximately £1.12 a day, we switched the heat off and the cost is 2p a day and yes there is some cool air directly underneath the unit but it’s not a problem. We installed it ourselves as we have electric in the attic so just fitted a 3amp plug. Very happy with this product.

This is definitely worth the price. Had it working over a week now and condensation has significantly gone down in the whole house. Can be loud when running on full, but hanging the unit has helped reduce the noise. Very easy to use and currently working on low and still making a difference.

After years of struggling with condensation and mould, I finally came across this one and convinced myself to buy it. The first one had a broken fuse spur and I had to return it and ordered the second one. After I install it which was a bit tricky, the condensation disappeared within a day. Amazing product.

No more condensation on Windows both the lads asthma has improved got the boost switch when the shower gets used. Got the heated version to be Frank it's not powerful enough to make a difference. Installed a radiator just beside it that takes the chill off.
