Don't get the fan blade type of exhaust fan with the small duct because they are loud and can not move as much air. Like are put in almost all new homes because they are cheap.
Good fans are quieter and better made, with ball bearings and have a bigger duct size and lots don't have the fan blade type but t

And others they have. http://www.nutone.com/product-catego...x=8&image.y=10

Ok, thats good advise, thanks a lot for that.

I like the look of the ones that heat too!!
Im just not sure I have enough ceiling space for that though :/..I'll have to measure up!

By any chance, distribute heat between rooms!??

Well a heat lamp one is not that much bigger then the smaller basic one but it is higher or deeper and that can help as long as it moves more air with a larger duct. Also what can help if you don't have to worry about others when you are taking a shower is don't close the bath door all the way so you can bring in more fresh air into the bath. May if you want to keep it close then you could get a vent for the bottom of the door. May be best to buy another door with the vents on it because if you cut a door vent hole your have to frame in the vent hole.

Only problem with a cracked door, is that if u have a smoke alarm nearby, they tend to false positive on shower steam and go off .

mm, Ok, thanks a lot for all that info guys

Good idea. Thanks, I will take that into concideration.

Sooy, what there is a type in my last post - Even though what you said is very true, and useful,

where I said this

By any chance, distribute heat between rooms!??

I meant to say, does anyone happen to know anything about the systems which dehumifiy, remove odour, and distrubute heat?

Many thanks again for the continued help.

Sounds like an air conditioner with an electrostatic air cleaner.

[Speakersrock]

mmm, thanks John. It could be, But I had heard these were also meant to be fairly eco...thats not an air conditioner is it?!

I think we may be back to the exhaust fan, even a small one. That would remove the moisture as well as draw in warmer air and fresher air from the rest of the house. A small vent in the door would facilitate air movement.

I never had any trouble and the smoke alarm was right there in the hall right over the bath door.

I used to always keep the bath door open when I was living at the condo and other places if I was in the master bedroom and used the master bath.
But at the condo I took out the fan that was there and put in a heat lamp fan. Opening had to be cut only about 3/8 inche more on two sides so was very easy to make it fix. Then the duct was 3 inche so was bigger then the one that came with it. The fan was the type you see in a water coolor or in your AC/Heater unit and not the fan blade type so it was not loud at all. Then once the red heat lamp burned out I got a white heat lamp I like even better because it help you see better when you was in the shower.

Hewee, i dont think newer ones will have that problem, mainly older ones if your house has an older smoke alarm. I had problems with an old one in my house a few different times. Goofy thing went off after someone took a hot shower.

Sure is odd thing to happen unless someone was smoking and told you they were not or you got it so wet with steam that it makes contact somehow.

[Speakersrock]

Ive had some older ones here until recently and they never went off...but hay..prehaps I was just lucky!


Thanks for all the other ideas guys, very useful.
Im still trying to weigh up whats the best option. Sill quite liking the idea of a heated one though as there o heating down there (not they you need it as it is only used in summer, and one the shower's on with no air removal lol....)

I'll keep thinkin!..thanks.

Actually, dehumidifiers are basically an air conditioner with the evaporator and condenser coils both in the airflow. However, when you add the air cleaner, that's when things get a bit more complicated, depending on how good you want the air "cleaned".

[Speakersrock]

Oh ok that figures!!

I was thinking about this while I was out today..made me think of something else slightly related.
I never have managed to work it out, for a computer case, what way arund is the correct and most efficient way for the fan to blow? Cooler air in? or warmer air out!?

[JohnWill]

Fans high on the computer case, typically in back, should be exhaust fans. If you use a front mounted fan, (I find them somewhat ineffective), it should be low and be an intake fan. Since the natural convection is hot air rising, you want the exhaust fans high to remove the hotter air and encourage cool air to enter.
