Learn about HVAC & Home Performance in Houston.
Most people are unaware that they are losing huge amounts of money by not optimizing there attic. Today’s topic is Solar Attic Fans:
How it works:
1. Heat Builds Inside An improperly Vented Attic
The sun beats down on a homes’ roof and heats up the enclosed attic space. Passive vents (soffit or gable) allow some circulation but do not provide the pressure needed to force out the hot air.
2. Solar Attic Fan Provides Air Circulation
The photovoltaic panel of the solar attic fan collects sunlight that powers the fans motor to increase air movement.
3.Air Circulation Moves Hot Air Out Of Attic Space
The increased air circulation provides the pressure needed to force out the hot air from your attic. Attic venting can cool your attic space by up to 40 degrees!
Why it’s important to you:
Attic venting can minimize the load on your HVAC system, letting is use less power. The lower usage of power is turned into instant savings for you AND the lowered load on your HVAC system will extend the systems lifespan.
Expected energy savings – Up to 30% of cooling costs each month.
