An electrician would install and "hook up" the fan while a heating and ventilation person would add the venting. In a scenario like that I would strongly recommend that the person get a stronger fan installed. As we calculated, your requirement is for, at least, a 61 CFM system. The actual vent power of your current fan is only 50 - (2 X 10) = 30 CFM. and the problem is compounded by the fact that you have two elbows in your attic venting between this fan and the outlet vent.
Let's say your current fan is only 50 CFM. To calculate the CFM requirement of a fan in that bathroom. An example: If your bathroom is 10 feet by 6 feet' you have a 60 square foot bathroom. Subract 10 CFM from that total for every elbow in the venting pipe you have in the attic between the fan housing and the oulet vent. Compare that number against the CFM rating of your bathroom fan (Cubic Feet per Minute - the amount of air your fan can take out of your bathroom in one minute). Take the square footage of the room and multiply it by 1.07. The formula for fan select in a bathroom is as follows. If warm moist air is going up the venting system and not being push out or is sitting up there because the damper on the fan housing is stuck open, the moisture is going to condense as the pipe cools and where's it going to go?. The other thing you might consider is that the fan in the bathroom is not powerful enough to properly clear the bathroom or exchange the normal moist air in the house. When cooking and boiling water in the kitchen, keep windows at least slightly open and again make use of extractor fans.

Make use of the extractor fan if you have one and if it’s not working efficiently, upgrade it to a better one. If you do discover any moisture in that area of the attic and can't see an obvious roof leak, I suggest you call heating and ventilation company to come and have a look. Showering and bathing should be done with the door closed and a window opened afterwards. You don't want any moisture being wicked into that insulation and storing there, waiting until the saturation point before disgorging all over your ceiling insulation, vapour barrier or, worse, your drywall. is there any? If so, if there are any seams open in the insulation wrap (the lower down the pipe, the better), stick you finger into the batting and see if there is any moisture. The other thing you want to check up in the attic (assuming you find no water) is the insulation around the exhaust piping. You don't want to find water pooling up there. I suggest that you go up into the attic and check out the venting as well as the area around the fan. 3) Investigating the duct pipe up in the loft to ensure it's not blocked. It died within 4 weeks due to the water coming through it. So far we have tried: 1) Fitting a new extractor.
Consider the dripping to be like an early warning system that you may have a condensation problem. The extractor fan in our bathroom (1st floor flat) drips in cold weather. through a seam), pooled on the vapour barrier until it found a place to escape, then showed up as a wet spot on your ceiling.
