Do attic fans use a lot of electricity.

Attic ventilation fans are typically mounted to an exterior wall in the attic. An attic fan may not reduce your air conditioning costs but a whole house fan is a different story. This is a solar panel supplying free electricity to the attic fan under the silver dome on the rear roof. The fan blades spin but they don t lower the attic temperature at all.

There are many reasons to doubt that your proposed fan installation will change the temperature of the attic enough to save any of the energy required to operate your air conditioner. For optimal results you need to add additional vents to draw in the cold air as they exhaust hot air. Whole house fans energy requirements are just 10 15 percent of what you could expect from the a c unit. Ceiling fans tend to use a similar level of electricity as a tower fan.

In fact the home power article states that a typical 250 watt fan would use 180 kwh per month if run continuously. And besides they are many ways cheap. But there s really a more fundamental reason that power attic ventilators won t help a lot and for some reason i didn t mention that in the original article. How much electricity does a ceiling fan use.

When turned on the fan draws cool air through the windows up and into the attic helping to push warm air out of the attic. Moreover it is certain that operating the new fan you want to install will increase your electricity bill because fans use electricity. This works out at 7 8 per month if used for 12 hours a day. Sources such as the billings gazette energy vanguard and home power all have articles that essentially say the same thing.

Attic fans are powered differently. Many are solar powered and require no other wiring so they don t cause any additional charges on your electricity bill at all. This will mean around 0 02 to run per hour depending on electricity costs. If you set a tower fan at high speed it will cost you much power than an amateur with low speed.

Attic ventilation fans also tend to be quite energy efficient in terms of their own operation. Gable fans fit into the gable vent and can be set to operate only within a preset temperature range. This type of system blows hot air out of the attic but it can have a negative effect. Just make sure you have the right climate to use one.

Attic power ventilators are simply not worth the cost and effort. Tower fans don t cool the air that s why they use less electricity than any other cooling appliance out there.
