Ten ways to keep cool was a sub heading in the Daily Telegraph. Some were sensible some were so ridiculous you could have ended up with the flu, they were also promising a heatwave in highs of 40°C. This was to come to fruition in a couple of days with Friday in Canberra being 36°C and the following day in Canberra was 41°C with the following Sunday having a 22°C temperature at 4pm, go figure that. On Sydney radio 2GB all day at the same time they were continually telling people how they could cool down and the possibility of 45°C in western Sydney whether this happened or not I do not know, they were also telling people where they could go to cool down, RSL clubs where saying everyone’s welcome, or people could go to large shopping malls.
There are many ways to make your home cooler HOWEVER A LITTLE KNOWN WAY TO KEEP YOUR HOME COOLER IS TO INSTALL AN EFFECTIVE ROOF VENTILATION SYSTEM.
We have our tile ventilators installed in our home, on the Friday when it was 36°C it never went over 28°C in our home, although we have air conditioning we did not use it, all we used was a $30 fan to move the air around.
The real difference with our ventilators is when you are trying to sleep at night. You will definitely sleep throughout summer after installing our ventilators.
On the day it was 41°C the temperature in our home never went over 30° that made a difference of 11°C, we did use our air conditioner for an hour to bring the temperature down to 28°C then we only used our fan, at 9pm it was 33°C outside and 25°C inside.
We went to bed that night and went straight to sleep. Whether you have air conditioning or not if you don’t have effective roof ventilation you won’t be sleeping very well unless you run air conditioning all night.
It is funny you can’t understand, you’ve opened all the windows, got a great cross flow and it is still hot – why? If you don’t have air conditioning you’re guaranteed not to be able to sleep. If you do have it, it is going to run all night - why? Because you are not only cooling the home you are cooling the over-heated air that is trapped in the roofspace and radiates into the home long after the sun goes down.
Don’t think a solar fan will do because when the sun goes down so do they, don’t think one or even half a dozen whirlybirds will work.
What you need is a balanced system of 2 ventilators of the same volume for each zone of your roof to move the ambient air throughout the roofspace, this will remove the over-heated air from the roofspace. Giving you a good night sleep and if you have to use your air conditioner you will be able to turn it off during the evening hours if you use our ventilation system.
