Roof Ventilation Sydney

How does a whole house fan work?

The fan allows the cool outside air into your attic, thus cooling your attic and contributing to a cooler house. The cool outdoor air flows through your home, effectively cooling living areas. Whole house fans cool down your home while also keeping the costs down. They are designed to pull the cold air into your home and to push the hot air out! A whole house fan acts like an exhaust system. Whole house fans and attic fans are often confused with each other; however, they achieve different goals. Whole house fans in Australia gained popularity in the 1950s, as they were cheaper than air conditioning and still kept houses cool.

A whole house fan draws hot air to the attic which then escapes through vents due to positive pressure. Then at the same time, a negative pressure is created in the living areas of the home which allows for the cooler outside air to come in through the windows. Whereas, an attic fan pushes hot air out of the attic and does not create the necessary pressure for the cool air to come into the home. They are often confused because whole house fans can be installed in an attic due to needing to be installed at a high point in the home. Whole house fans are an alternative to air conditioning because they keep the house cool, whereas attic fans do not. They are an economical and practical way of living.

This solution is also extremely affordable compared to air conditioning. Whole house fans can rapidly cool down any building. Newer models are environmentally friendly, quiet and energy efficient, making them a great way to reduce interior temperatures rapidly. For the most effective results, windows must be open, and they work best in the morning or evening when the air is nice and cool outside. The whole house fan will draw in the refreshing cool air from outside. Depending on your climate, a whole house fan can be all you need, with no need to use an air conditioner. In addition, whole house fans in Australia are significantly cheaper to run, and with an energy efficient whole house fan, you could cut energy costs by 80%. They operate at one-tenth the cost of air conditioning according to home improvement experts. A standard whole house fan usually has a diameter of 24-36 inches; however, this may be adjusted depending on your living space size.
