Review: I fitted one and wouldn't be without it - I fitted one of these to my house one year ago and can confirm that it does exactly what it states. The problem I needed to overcome was moisture on the inside of the windows during cold weather and this unit solved it. Although we have double glazing throughout, moisture would still gather overnight, especially in the bedrooms. Before buying a Vent Axia PIV I read various reviews ranging from 'this will change your life' to ' it fell apart when I took it out of the box.' Well here is a review from someone who has had it running for a year. the installation was straightforward and took about one hour; but will take longer if you need to run a power supply to your loft. The noise from the fan is minimal and after a while you stop noticing it. It draws filtered air from the loft area so the draught can be cool in Winter months but I can put up with that as the moisture prevention benefits far outweighs this. Added benefits I have noticed are reduced hay fever sneezing whilst in the house and less cooking smells about the house. So, if you are tired of mopping the inside of your windows then this is the product for you.
Review: Prevents mould when opening the windows isn't really an option - I found myself an accidental landlord after I had to move to another city but my home didn't sell. So I got tenants, who after a few years said they'd started getting mould in places. The weather was atrocious and I couldn't say have you tried opening the windows and getting some ventilation once in a while, so I ordered this and had it fitted in the loft. It's done the trick and the air flow it's created has prevented a recurrence of the mould. In terms of noise, I've not heard it ever when I've been over there. In terms of value for money, functionality and quality, no complaints from the tenant about mould means that it's earning its keep and doing exactly what it was bought for. It's installed up in the loft, so no issues with fit, either, because it's completely unobtrusive.

## Questions & Answers

**Q: What temperature approximately will the heater give out**
A: The heater can be set to heat the air at between 5-20 deg C. I have mine set to 10 deg C, just to take the chill out of the incoming air. This unit has worked very well so far for us. Our RH values have come right down from high 70's upwards to mid 50's or lower. It's worth checking your loft ventilation, I had to add additional lap vents to ensure enough airflow.

**Q: Is there a model for use in a apartment without loft space?**
A: Never recieved the item, out of pcket to the tune of £390. Amazon being very unhelpful to date.

**Q: I put this in a house I rent out and the tenants are complaining that the air coming down is very cold. Is this the same with your units?**
A: It is the same for me.  Have to remember it takes the air in the loft, which is going to be cold at this time of year, filter it and pump it back into the house.
Have you thought of increasing the output on the heater.  You can set it to up to 20 degrees so it heats the air as it pumps it in.  I only set mine to 5 degrees. 20 degrees would be about 500 watts.

For me it reduced the condensation by 99%. Only when it gets to minus 5 have  I seen a very small amount of condensation

**Q: Does it automatically come back on after automatic shut off for high temperature?**
A: Yes, if the loft temp is too high it stops, then restarts once it cools down.

### ⭐⭐⭐⭐ Works well and not expensive to run.
*by J***R on 21 December 2025*

Works extremely well in preventing condensation and mould. Slightly sceptical at first but significantly reduced humidity in the house. No more problems with condensation on windows. Only minor problem is that the air output temperature doesn't come out at the set level.
