Bathroom Fans

Hi all,

I need to install a fan in the bathroom.

Is an exhaust fan (~$100) that exhausts outside better than a 3in1 heat+fan (~$120) that exhausts into the ceiling?

Blauberg 150mm Autoshutter Fan Exhaust

Thoughts?

 

I've recently had a 250mm ceiling HPM fan installed in one of my properties which had an issue with mould due to a cheap fan and it works very well. I hooked it into a sensor so that it comes on every time any motion is detected, this way I ensure that the fan goes on as not every tenant would care to put the exhaust fan on.

 

@Mr Dabolina Does it exhaust into roof or outside?

 

I installed whatever was on special at Bunnings for $15 for a 250mm fan that exhausts into the roof space. If you are concerned that tenants won't turn it on, wire it so it comes on when they turn on the light.

 

Wiring into the light is always a good idea. I tend to vent to external in particular in humid climates or where minimal roof space (low pitch roof). I'm putting a Kado Lux 250 mm in house in Mackay now but Bunnings prob have something comparable.

 

I had a 3in1 installed there previously.... i dont know if that caused increased moisture into the house.

So im wondering whether venting outside is actually a better option.

Also the 3in1 doesn't allow a forced turning on a fan, which is what I would like to do (because for all i know the tenants probably never turned it on).

 

The 3 in 1 have a smaller fan i think. So don't work as effectively. better to get the heat lights and a separate fan.

Roof or external probably has some science to it depending on the building but to the roof is probably ok in most cases

 

I've always found the idea of venting into the roof space kinda weird.

 

roof but i think you could duct it out as well

 

I originally wired it into the light but the bathroom has big windows and lots of light which mean't that the tenant did not have to turn the light on during the morning / day and hence no exhaust fan.
