Just buy one
If you live in a bungalow just get 1 Solved all our wet window issues, it took me around 2 hours to install with no problems. It started working as soon as we turned it on. It circulates the are around the bungalow so there are no warm spots or cold spots. It is situated above a radiator and circulates the warm air. GREAT IDEA JUST BUY ONE

Cure to out damp/condensation problem
I installed this on the landing ceiling, and it has been in a couple of days and we have seen visible differences all positive results, The fused spur which came with the item was broken but been an electrican this wasn't an issue as I have these in stock, I would always recommend getting an electrican in to install a supply in the loft as for a DIYer this may a tough as as wiring could be different in old and new houses.

It really does work!
It was just by chance my wife saw this and after checking prices and reviews Amazon came out on top. Was sceptical at first but installed it yesterday, set it up and "hey presto" all the condensation we normally get every morning was gone. Our unit came with the added humidty meter (standalone not part of the installation) and it said before I switched it on it our humidty was 81%......within 4hours it was down to 50% and you could visibly see the condensation disappearing. This morning none whatsoever and the house is sitting at a comfortable 45%. Best thing we ever bought. I got the heater version as the air in our loft can be freezing being in Scotland. Easy to install (DIY intermediate) but electrics should be done by an electrician. I the unit comes with a fused spur but I changed it for a switched fused spur for convenience. Set up easy.

Wet windows and mould will go with 2 days.
These are brilliant. Most houses are sealed up to prevent heat loss and then moisture builds up and then mould on walls. Install one of these are it gone within a couple of days (you will have to clean the mould away that’s already there). I bought this for my son’s house after we bought one and been running it constantly for 5 years. My sister in law has also bought one and again wet windows are all fried up.
