Now for the first time in history homeowners with no attic can install a powerful whole house fan to pull hot air out and cool air in the windows.
The Thorwaldson Tornado rooftop whole house fan pulls a whopping 8000 cubic feet of air every minute. Imagine – if your home is 3000 square feet with 8 foot ceilings that is about 24,000 cubic feet of air. The Tornado will move it all in just 3 minutes! The best news is that this fan is not expensive. It is priced at the same cost per CFM as the lowest cost attic mounted whole house fans, 28 cents. Here is a comparison.
Here are the components of the fan.
- The shell with motor, blade and damper and the rain hat – the Tornado turbine. The turbine is on top of your home’s roof and can be hidden by the surround below. The shell below is best located below your ceiling and hidden by the cabinet seen below.
- The rain hat surround – prefabricated brick or stucco look. It can be any material look – painted stucco, painted metal, brick, or any other you prefer.
- The shell surround – a simple 24 inch by 24 inch kitchen or hallway cabinet. Tt can be any style or color or wood look that you might prefer. It is 20 inches high and mounts to the ceiling to cover the bottom of the fan shell seen above.
