Yah..my roof is leaking but not relevant to this...as the leaking at front end, and ventilator is on the back end part.

Here the link about the issus

How's the performance so far? Do you see any difference in the heat? Is it more bearable now without the fan or air-con.

anybody got installed or tried solar powered ventilators ?

eg like this http://www.scorigin.com/solar_fan__ventilation

Saw this on their website last week. However, the online sales is non existence.

Old thread...

Any users mind to share effectiveness of wind turbines for terrace houses?

good reference from panasonic:

yeap, how is the noise and dust issue so far? occurred?

For those already using the this for a long time, how is it? Any problems with the wind ventilators?

Does this work for low ceilings? Mine is like 7.5 feet from the bottom tiles to the top ceiling where the vent should be installed so not really sure if it would really 'suck out the hot air'

Can any share feedback on this air turbine ventilator? not sure is it really effective? How about solar ventilator? Pros n Cons both of this?

I still think the cfm from a couple 8" or 10" fans on the rooftop section (why not bigger = so thieves cannot pop in so easily if they can't fit their shoulders through the hole) at ~318/530cfm each will provide better active cooling effect. It does need a input vent (maybe toilet ceiling vent) for cold air input

So any good band reliable band ro reconmend for turbine ventilator nowdays?

just wondering whether its possible to install ceiling ventilation fans without the turbine ventilator? can we vent out thru the side roof instead or any other options?


asking due to MCO the shop is charging extra for installation..

I have ceiling ventilator fans in all the rooms and living hall on the 1st floor without a wind turbine. The purpose is to prevent heat built up from non air circulation.

Is better if there are wind turbines to extract the hot air. If depending on the gaps of side roof tiles, the heat exchange is slower.

Better to have preset timer to switch on the ventilator instead of waiting for the heat to built up.

thanks for the reply, so far does your 1st floor rooms feels less heaty?

for my current place it does not have any small living room, just a walkway from the stairs to the room on the upper floor, so everyday morning that area feels stuffy and heaty since all other rooms doors are closed so wanted to get rid of this issue..

dont waste money with these silly roof turbine fan. not only will there be leaking during thunderstorms after some time... the suction is so weak during day time...you cant feel any difference.

The best is to install a CEILING Ventilation FAN on the CEILING on the first floor. If your house has only ground floor then install on the ground floor ceiling.

this way HOT air can escape upwards and cool the whole house

Is better than b4 installation. I have a timer for all the fans which will switch on at certain preset time on rotation to prevent heat building up.

points noted but if no opening on the roof can the hot air escape via the roof tiles in time? or it may ended up as stale air in between the roof and the ceiling instead..
