  • Cool your whole home including the roof for about 8 cents an hour compared to air-conditioning which costs up to $1.50 an hour
  • So you could run the fan for 12 hours during the evening and overnight for less than a dollar!
  • Costing up to 80% less than air conditioning to run
  • Up to  40 entire air changes per hour in living areas and up to 60 in the roof space
  • Manufactured and very successfully used  in America since the 1940s as a cost effective alternative to air conditioning which pays for itself over time
  • It’s simple yet very effective design is ideal for the Australian climate as cooling fresh air moves over your skin to cool you naturally just like fanning your face on a warm day
  • The healthy choice as fresh air is drawn in and hot stale air, odours, mould spores, dust mites, moisture and pollutants are expelled
  • Free yourself from a closed up home and there is no oven like heat keeping you awake at night
  • Invisible, quiet and virtually maintenance free, we have customers who have had the fan installed for over 30 years and they are still going strong!
  • Efficiently cool homes, schools, churches, nursing homes and industrial buildings
  • There are 5 sizes available to suit any size home and  in some large buildings several fans may be required 

Beat the soaring electricity prices and save power by combining a whole house fan cooling system with radiant floor heating or Nobo radiant panel heaters for an energy efficient, healthy and environmentally friendly alternative to reverse cycle air conditioning.

  • Modern homes are built using high mass materials such as bricks and tiles which absorb heat, are often insulated and are usually poorly ventilated. So they heat up like ovens, even in moderate temperatures
  • Our Whole House Cooling Fan is simple yet very effective by using the principle of nature’s own cooling system, of shade and breeze. Your home provides the shade and our powerful fan provides the breeze to prevent the build-up of heat in rooms and the roof space so air is always cool and fresh and not recirculated
  • The fan is installed inside the roof space and in the ceiling opening below is an air actuated shutter which closes down when not in use
  • Windows and doors in the rooms you wish to cool are opened. You then switch on the fan which immediately opens the ceiling shutter. Fresh outside air is drawn in to replace air which is sucked out of rooms through the house towards the fan
  • The air passes over people to pick up radiant heat before it can heat up people in the room. For people in the house the moving air feels far cooler on the skin than still air, despite the ambient temperature and is refreshing as it relieves the oppressive stillness
  • The hot, stale air passes through the shutter into the roof pace where it continuously pushes the roof space air outside under pressure via eave or gable vents or through whirly birds if they are already installed
  • The air is expelled rapidly so in- roof temperatures remain close to those outside, because no heat is allowed to build up in the structure of the home the temperature of the whole house is lower
  • You can direct breezes through certain areas by opening and closing windows and doors to gain more concentrated air flow for example through living areas by day and bedrooms at night to give effective cross flow ventilationBreezepower Cooling Fan and Motor

Testimonials

Hi Tim

I first read about the Whole House Fan in 1987. I kept the newspaper clipping and when I moved house I followed up and installed a unit 5 years later. My wife and I were delighted with the results, and since then have installed the fan in our two subsequent homes.

Our experience has been that the fan easily meets and sometimes seems to exceed the temperature reduction rating, especially if you can draw air from areas around the house shaded by trees and plants. We far prefer the solution to air conditioning for comfort and air quality, as well as being far cheaper both to install and run.

For cost effectiveness and functionality, the whole house fan is a far superior way of reducing carbon emissions than more widely known and promoted energy saving devices,  and I believe should become the preferred way of controlling summer temperature in Australian buildings.

Tim,

Our fan was installed 29 years ago and remains one of the best pieces of equipment we have ever invested in. When the original motor recently ceased to operate on more than one speed it was marvellous to find that the product is still on the market. We would have no hesitation in recommending the installation of a whole house fan, to anyone. There are very few days when we ever find it necessary to run the A/C and when we do, it is only during the hottest of days during heat wave conditions. At all other times, the Whole House Fan does the job of cooling the place down admirably.

Regards

P.S It is also magnificent at clearing the house of any unwanted odours should there ever be a mishap in the kitchen!

Hi Tim

I have had over 12 trouble free years (until very recently) using your Breeze Power Whole House Fan to cool my house down during summer.  That’s pretty good considering the amount of use it’s had. I have just had your repairman out for the first time, and found his service to be very professional prompt and his advice quite helpful.

I also love being able to control the direction and power of the breezes by opening or closing certain doors or windows throughout the house. We have also found the fan to be very useful in preventing a build-up of condensation during or after a period of heavy or consistent rain, when the house has had to be shut up, and the air can become stale.

Kind Regards

Dear Gill and Tim,

I have now had my whole of house cooling fan for about 8 years and  while the inside temperature is only around 4 to 6 degrees cooler than the outside on the hottest days I have never been sorry for making that choice over other methods of cooling. I have never liked the idea of sealing the house up to cool it, and with this fan I don’t. I liken the effect to sitting on a verandah with a pleasant breeze blowing. The strength and direction of the breeze is governed by the number and placement of windows and doors that are open and the speed of the fan. The heat and/or stuffiness of a closed house is soon removed once the fan is on and a couple of episodes where burnt toast etc have threatened to pollute the furnishings and so on with smoky smells have been swiftly dealt with by the whole of house fan!  Of course the cost of running the fan is very small compared to air conditioning as well! While it is possible that the sound of the fan could be intrusive, mine was installed in the bathroom where the sound is not an issue. I definitely recommend this fan.

Yours sincerely,

Stephanie

Hi Tim and Gill

We had a Breezepower Whole House Fan installed 8 years ago and it is the best device we have in our house and we just love it! Each summer we turn the switch and off she goes!

We love the feeling of breathing in fresh air and it is so much healthier than being cooped up in a home breathing in stale air from an air conditioner. We usually put the fan on late afternoon when the air starts to cool down and it is particularly useful in cooling the upstairs area of our house where our bedrooms are so we are all comfortable when we go to bed.

The fan has paid for itself many, many times over in cost saving and there is no maintenance involved. I would recommend the fan to anyone and wish more people were aware on this wonderful invention.

I have always suffered from asthma and when my second son started to get bouts of it I decided to look at ways to minimise the triggers in our home. I found Low Energy Living on the web and Tim was so helpful in suggesting a healthier and also energy efficient solution to cooling and heating our home.

Since installing the whole house fan 2 years ago there has been a marked improvement in my son’s asthma as well as my own and the fan does a sterling job keeping us cool and saving us money as well.

This winter we had Nobo heaters installed and I am thrilled with their performance also. So now we have a complete cost saving alternative to reverse cycle air conditioning which I would highly recommend to anyone. Thanks Low Energy Living there should be more companies like you!

Hi Tim

We originally saw a whole house fan working when we went to visit some friends in America some years ago. Apparently they have been around there since the 1950s but went out of fashion when air conditioning became affordable but now with the ever rising cost of electricity are popular again.

We were so impressed that we decided there and then that we must get one installed in our home in Sydney. We found out that the fan is actually made in Arkansas near to where our friends live and shipped out to Oz.

We were thrilled when we tracked down the NSW supplier which was Low Energy Living and Tim’s wonderful team of contractors was able to install one for us before the summer heat began.

The fan is marvellous and we just wish more people knew about them. At night we often have it on low and we sleep so much better now. We also like the way that you can concentrate the air flow through certain areas depending on which windows and doors we open and close.

FAQ

What about heatwave days?

  • There will be some summer days with extraordinarily high temperatures when even air conditioning systems struggle. We do not pretend that we can maintain comfort at these levels with the house fully open and the super-hot air being drawn through it
  • If you have air conditioning this is one of the times in summer you will use it but only for a few hours instead of 8 – 12 hours a day for the whole summer. In fact relying only on refrigerated air conditioning to cool your home in summer is as logical as running a fridge in an oven!
  • You will always start the day with a “bank” of cool air inside your home. On very hot days the best way to use our cooling fan is to close up windows and internal doors to conserve the cool air in your rooms and shade exposed windows
  • Keep the cooling system on low speed and open just one or two windows on the shady side of the house as close to the system’s ceiling shutter as possible. This will enable the cooler shaded air to be drawn directly into the roof space to continuously change the air during the hot hours to keep roof space temperature levels down. Meanwhile the air in the closed off rooms is not disturbed and they are receiving far less radiant heat from the ceiling, as furnace like heat build-up in your roof space is prevented
  • Once the outside air temperature has fallen as the sun goes down, you can open up more windows, switch the fan on to high and bring in the cooler air through your home and enjoy a comfortable night’s sleep.

Why doesn’t the Fan bring in hot air?

  • When you use the fan your home is much cooler because there is no trapped heat in the rooms or roof space
  • When air flows over your skin you feel cool even though the air itself is warm.  This is called wind chill and is how fans of all types cool you. You get the same effect when you are outside on a breezy summer day
  • Night time is usually the time when heat in the house is most trying because it is hotter than outside. With our cooling system your home is structurally always as cool as the night air with the additional wind chill cooling that you feel with the gentle air movement on your skin

Why not use ceiling fans in various rooms and a roof vent like a wind turbine?

  • The secret to cooling by ventilation only is the air speed you can generate and no wind operated or even motorized roof space ventilator can match our Whole House Fan Cooling System. Our cooling system changes the air in the roof space up to 60 times an hour and up to 40 times an hour in living areas, ensuring a fresh, healthy, cooler environment
  • Ceiling fans recirculate the same hot, stale air. In fact in summer they can help distribute the heat radiating down from the roof. If you have 3 ceiling fans you are using as much electricity as one Whole House Fan which cools the entire house!
  • Wind turbines and other roof vents release hot air very slowly so heat will still build up in the roof space.
  • Some whirly bird suppliers install ceiling vents in rooms to “remove the heat from rooms”. In reality, wind turbines expel hot air from the roof too slowly to have any effect on the room below, particularly during the hottest hours of the day. In fact, hot air from the roof space may even enter the room below via the ceiling vent because the volume of air in the roof expands as it heats up.

Where is the Whole House Fan Manufactured?

The Whole House Fan has been used extensively as a cooling method in the southern states of America since the 1940’s with great success. The fan is manufactured by Triangle Engineering the largest supplier of air movement products in America and the rest of the quality parts are mainly made in Australia where the system is assembled to the highest standards.

What Warranty is provided on the Whole House Fan?

Full 2 years warranty offered on the fan belts, metal mounting frame, timber plenum and ceiling shutter and 1 year warranty on the motor, belt and control switch. It should be noted that all the fan components are long lasting and seldom need any maintenance.

How quiet is the Cooling Fan?

  • The fan in the ceiling is belt driven so there is no motor hum and the motor is silent
  • Having six blades produces less air turbulence and each blade is uniquely sculptured with static balancing ensuring maximum air flow with minimum wind sound
  • The fan is mounted on rubber to eliminate vibration
  • The sound you hear when the fan is in operation is the soft diffused sound of air whooshing through the fan blades
  • The noise level of the fan is rated to 42 decibels being the sound level of soft background music, which is the level approved for classrooms, offices, libraries etc

There are 5 Fan sizes to suit alll installsWhat does the Whole House Fan Cooling System consists of:

There are 5 different sizes of fans to suit any type of domestic, industrial and commercial installation.

Each fan kit consists of:

  • A large, six bladed, belt driven, quiet in roof fan installed invisibly inside the roof space(the smallest fan has 4 blades)
  • A single automatic ceiling shutter on the ceiling below – wind operated or motorised and sized to suit selected fan and the roof type
  • A motor
  • Vents installed preferably under the eaves or on the roof. Gable vents if there are no eaves.
  • A variable speed, wall mounted switch (optional timer available)

Where is the Cooling Fan usually located in a home?

  • In a single storey home the fan is positioned in the roof space on the ceiling joists over a hallway where rooms lead off. An air actuated ceiling shutter covers the ceiling opening just below the fan. A control switch is located on a nearby wall.
  • In a double storey home the fan is placed over the landing area of the top floor again where rooms lead off.
  • In a half cathedral roof ceiling /half cavity roof design the fan and louvre can be installed vertically.

I have no roof space and/or have cathedral ceilings can I still use the Cooling System?

In homes with flat roofs or cathedral/raked ceilings our cooling fan can be installed very successfully in roof mounted canopies with louvered sides. In this case no vents are required. The canopy is customised to suit each project in terms of size, shape and colour.

We recommend a motorized ceiling shutter to be used with a canopy to prevent the shutter blades rattling.

How does the Cooling Fan work so well in larger buildings?

  • Buildings such as schools, churches, nursing homes, community centres, indoor sports centres and warehouses are all large spaces that accumulate hot air are prohibitively expensive to air condition
  • They need a dual approach to providing more comfort for people living and working in them – the removal of hot air at a continuous and controllable rate with air movement to provide subtle wind chill cooling on the skin with perhaps some air conditioning for extreme days
  • Our natural cooling system is the answer to this problem we have installed fans in many commercial projects and have had very positive feedback on the efficiency, cost saving and health benefits of the system

Can I install the Whole House Fan myself?

We usually organise the system to be installed by one of our experienced electricians but the system does come with a full set of installation instructions so you can install it yourself and get an electrician to connect up the electricity and controller.
