i get the impression it may be a few quid more expensive tho?
Mine cost £300 and fitted it myself. (Had power to the loft already)
Just sucking up all the water isn’t solving the issue.
OK your saving £250.
* However you house will be taking longer to heat, therefore costing money
* Your having to do something on a daily basis
PPV you don’t know its there, costs peanuts to run, and is making the air in your house much fresher.
This PIV thing, wouldn’t it be cheaper just to install those ceiling fan thingys?
I reckon not, ok a fan would push air around the house, which would help, but PPV pulls in dryer air from the loft space which pushes out the damp air. ( I was very sceptical too until I saw the results.) Our house used to have relative humidity of about 80-85% now its about 60-65%
