I am sure that many of you will recall that for awhile - years - i have been be moaning the problems of my kitchen, condensation and mould (1950's bungalow). I have it all year round but in winter it is at its worst.

Having tried everything I eventually got my OH to put in a PIV ( nuaire eco with heat but we do not have the heat unit on as it happens). Well, after a month, I think I can say it is working. The walls are drying. The mould has not returned since I cleaned it off just after Christmas and all the rooms have lost the must smell ( although the kitchen is still musty smelling).

I also use a dehumidifier still when cooking ( maybe I need a vent for the cooker in the kitchen?). But the walls are now drying off and the windows are free from running water and everything seems to have imporved significantly.

Now maybe I will be able to re paint, clean and have a mould free and cough free life.

Thought I would share that.

You need extractors at both kitchen and showers if you have one.
There also needs to be means to let the air you extract be replaced (ie an air "intake")

Be aware of any chimneys. Extractor fans can suck air down the chimneys and hence combustion fumes into the house.
