Attic fan- before I invest - has anyone actually measured to see if it changed the temp? 2 part question thank? - dc exhaust fan
1) This is the lowest of the line solar DC fan 800 m³ / min to approximately $ 250. I am in a position to 114f in the attic and now they want to do everything possible to reduce the electricity bill. When I asked what someone saw a physical difference for the purchase justified?
2) I have a "pyramid" (sorry) with 3 roof vents static on 3 sides of the roof. I need the air intake and performance exhaust vent?

Personally, I have installed ceiling fans and do a good job of clearing heat in the attic. it is very fast and the aim is to make your home cool with AC and no heat in the attic. give only about 10 minutes.
I have installed directly mounted on the housing luver ventilation. need, but more is always better, sometimes.
Note that you do not want to spend more money than the 250 for the device and an electric fan and air conditioning. I'm sure you can install the device itself in about 30-40 minutes. There are only 2 son and a grounding cable. You can not spoil. If you wish, through you, then send me an answer on this page. I received an e-mail and answer all your questions.
His big question is why it is hotter than the attic, it is outside? Your attic should be the same as the outside temperature. The problem is, the roof and the building does not reflect the sun's radiation, which is irradiated.
The same principle that the microwave oven used, the frequencies of rapid movement, which polarize the roof at high speed and generates heat. Once generated heat is transferred within and atmospheric radiation.
Its roof is baked daily and the fan runs constantly while trying to escape the hot air.
The shadow of the roof, protected against the solar shingles or coatings isolate resistant to the roof of the heat is less inside. Cool roof technology was unbelievable in the infrared. If the house is new, should be under warranty because the building designed to reflect solar radiation.

Do not generate heat, and will not be a problem.
Why does a large amount as $ 1000 for the use of solar or wind power when the opportunity may have to build your own house, making solar systems for under $ 50.
You can use this system, the device used primarily to you in your home: refrigerator power, washing machine, computers, televisions, lamps.
In addition, you can also take them with you when you're camping, because it is very portable.
