Powered Attic Venting

POWER VENTING

The importance of venting your attic cannot be overlooked.  In cold climates, improper venting can lead to moisture build-up which causes mold growth, wood rot in extreme cases or even ice in the attic insulation. In hot dry climates, stagnant air can dry out your trusses, increase your energy costs for air conditioning and make your house uncomfortable. 
If your home is like most that we inspect, it is severely under vented.  You can add more soffit and exhaust vents but at what cost?   Power venting may be a more cost effective and  efficient method of achieving your goal.   However, venting is just part of the problem.   A well ventilated attic will reduce the convective load.  The largest component of heat gain or heat loss in any home is infrared heat.  Control this and you can really save! 

We have found in our full scale testing of homes with a radiant barrier installed that passive venting is not sufficient to remove the millions of BTU's changing direction from the reflective surface and that power venting is required. 

Solar Fans:  Sounds like a great idea right?  Sun comes up, creates free energy, spins a fan to remove the hot air from the attic.  In theory this makes sense.  The reality however is much different.  Question:  "At what point during the day will the solar fan put out the most amount of power?"  (assuming a Southern exposure for the PV panel). Answer:  Solar noon. Next question: "When does the attic require the most amount of venting?"  Answer:  Between 1:30pm and 7pm.  When the attic requires the most amount of venting the solar fan is putting out the least amount of power. 

  We import a vibration free, powerful, reliable powered attic fan manufactured in Germany.  This attic fan is unlike any other available:  quiet, powerful and very efficient.
We include an adjustable thermostat and an optional mounting box with this system.  This fan features an external rotor to which the fan blades are welded.   This unique design reduces blade flex and vibration and eliminates one of the shaft bearings. 
The bearings are sealed and never need attention.  Install it, set the thermostat and forget about it.  The 14" fan consumes 245 watts.  At a national average
of .10/kwh running for eight hours a day  that's less than $6 per month.  There are sites on the 'net that say the power consumption of an attic fan does not offset the cost of running it.  The goal is keeping your A/C off as much as possible which consumes 1600 watts per ton.  Logic would dictate running a fan for $6/month would be preferable to longer run times on your A/C unit from the stagnate, overheated attic air and the load on your ceiling.


This shows a typical home store attic fan installed on a gable vent inside the attic.  Although the mounting looks secure, the application is incorrect since the space around the fan is not blocked off.   The fan will create a negative pressure behind the fan and will draw air from the closest point, in this case, from vent openings around the fan.
This means very little air will be exhausted from the attic and most of it will be drawn in around the fan.  
The open area around the fan shroud (the round ring), needs to be blocked off with cardboard or wood to make this type of installation effective.  We see this type of installation on almost every home that has one!  The following are examples of what not to do!

 

 

This is the 14" German fan mounted before the area around it has been blocked off with cardboard.

The installation seen above was installed by an engineer.  This will have virtually no effect on 
exhausting air from the attic at the opposite end since most of the air will be entering around
the fans.  As you can see he also installed fiberglass up against the roof decking which will
only serve to store tremendous amounts of heat all day, cook his roofing system then allow
it to dissipate long after the sun goes down.  The people who bought this home had $475/mo
energy bills for a 1500 sq foot home.             

                     

Here is a roof mounted German fan mounted where a Home Depot fan used to be.  The dome shaped attic fan cover on the roof has been replaced with the correctly sized Aura Vent.

 

Two 10" fans mounted side by side.  Choose this option when a large vent is not available.

Warning: In homes that have gas appliances such as water heaters or furnaces in the attic, great care must be taken to insure adequate intake venting is provided (gables/soffits), so as to not create a negative pressure that will draw fumes down the chimney of gas appliances.   Installing an attic fan in this application has the potential for fire or filling your attic with carbon dioxide.  Just make certain there is sufficient intake openings to circumvent this situation.

Which fan looks like it's more efficient at moving air out of your attic?  Over the years we have found home store attic fans to be a liability to our installations and the only weak link in our proven NRG Package.  Since a properly installed radiant barrier increases attic air temperature by keeping unwanted heat from getting to the insulation, removing this waste heat has forced us to become experts in attic ventilation.
Home store fans like the one pictured are under powered, last one year (if that), and the Chinese thermostat is inaccurate, sticks on (or off), creates call backs and problems. Recent news is they are catching on fire after they sieze up. Sure the nice one costs more but like anything else, you get what you pay for.

PRICING OPTIONS:
Price includes the fan with thermostat and 6' of control wire pre-wired to the thermostat which speeds up the installation.  You need only to mount the fan, mount the thermostat using the supplied junction box and wire nuts and bring a 110volt power supply to the thermostat.  Prices below also include UPS ground shipping.  We strongly suggest the sheet metal support box to facilitate the installation...it's the best $40 you'll ever spend. 


SUGGESTIONS FOR SIZING (go to the next larger size for steep pitched roofs)
8" fan    304 CFM     $247   (sufficient to ventilate attics up to  500 square feet)
10" fan   624 CFM    $312  
(sufficient to ventilate attics up to  700 square feet)
12" fan 1208 CFM    $345  (sufficient to ventilate attics up to 1375 square feet)
14" fan 1800 CFM  $368 (sufficient to ventilate attics up to 1850 square feet) 
16" fan 3054 CFM     $444 (sufficient to ventilate attics up to 2800square feet)

(The above recommendations are sized for attics with a roof pitch between 2/12 and 5/12 pitch.  Steeper roofs have more volume and thus need the next larger fan to obtain the necessary air exchange per minute.  Roof orientation (South/East, etc), and roof color also are considerations.  If your needs dictate more venting because of these parameters, order the next size up to be safe.)

Pricey?  They sure are, you could buy four home store fans for the price of one of these....then plan on replacing it every year because that's how long they last (see testimonial below).  Once this job is done, you never want to see it again. This one you won't because of the quality, the thermostat and sealed motor bearings that never need lubrication.   
If you open the box upon delivery of this item are not totally impressed with the craftsmanship and quality, return it for a full refund.  We'll even pay for the return shipping!  We are that confident of this item.  We do not offer any product on our site that we have not field tested and trust for our online customers.  (hundreds sold, one return). 
 
attic fan close up viewShown with optional fan mounting box and 6' of romex  pre-wired to an accurate, adjustable thermostat.  You need only to mount the included 2"x4" junction box (near the peak of the roof), and supply a source of 110v power to the thermostat.  We've done most of the work for you!  Shown here is the blue plastic junction box with the unit pre-wired, just add power! Set the Thermostat at 110f and forget about it, no oiling, no service is ever required.
Simply mount what you see to the left over a gable vent or large size roof vent (at least 14"), mount the thermostat, add a power source and start saving.   Most of the work is done already!  You will need a hammer to mount the blue box, a screwdriver and drill to mount the sheet metal box to the vent.

We fabricate this sheet metal fan box for our Phoenix installations and thought we should offer it to our online shoppers as well.  
The design allows for a smoother discharge of air as it fully takes advantage of the aerodynamic design of the shroud and large side flanges.  The mounting box also decreases the installation time as the fan is pre-mounted to the box.  Just hold the box up to the wall or roof and screw in the entire assembly. 
$40 and no shipping cost if included with fan order

From our fan customers

"Dear Horizon Energy Systems, I just completed the installation of your attic fan and it runs beautifully - I purchased the 10 fan with the mounting box and it fit like a glove between the joists, I slid it in between the joists and blocked it in and connected the wires following the instructions online and by phone/email and it is running smooth and quietly - Im very satisfied and kinda proud.  What I appreciate the most is the support from you (Brad) at Horizon Energy Systems - I called and emailed several times because I am a novice at carpentry and electricity and your patient support made me confident I could do my own install and save some money (my two estimates seemed high I at $450 and $650 here near D.C.)    At first the installers said this was a gable only fan, however there is no reason it cannot vent through the roof - mine does.  Thanks for the great fan - this one is much quieter than the old one and I expect will provide many years of reliable service to keep my attic cool during the hot Virginia summer.  Keep supporting the great products and support to your customers - I expect to be a repeat customer if my next house needs attic ventilation."  

Thanks, Brian Collins
 

THE 12" FAN ARRIVED YESTERDAY {Friday June 23, 2006} AT APPROXIMATELY 12:00 NOON BY UNITED PARCEL SERVICE AND I HAD A CONTRACTOR INSTALL IT TODAY {Saturday June 24, 2006} IN THE FRONT PART OF THE GARAGE ABOVE THE DOUBLE OVERHEAD GARAGE DOOR OPENING WHERE A "VENT" WAS PLACED WHEN THEY BUILT THE HOUSE FOUR YEARS AGO.      YES, THE TWO ROOF VENTS OVER THE GARAGE WERE BLOCKED OFF BY STAPLING BOTH WITH A PIECE OF CARDBOARD PER YOUR ADVICE SO THAT THE ONLY AIR NOW COMES FROM THE FIVE (5) ROOF VENTS OF THE HOUSE PLUS THE SOFFITS.     AND YES, THE FAN IS  INSTALLED CORRECTLY BY HAVING IT COMPLETELY ENCLOSED IN A BOX MADE UP OF A PIECE OF 3/4" PLYWOOD {A ROUND HOLE CUT INTO IT FOR THE FAN} AND ALL FOUR SIDES WITH {2" X 4"}.    THERE ISN'T ANY "OPEN AIR SPACES" AROUND THE BOX AS THE BOX COVERS THE ENTIRE VENT AREA PUT IN THE FRONT OF THE GARAGE WHEN THEY BUILT THE HOUSE.

NOTE:   THE OLD FAN WASN'T INSTALLED PROPERLY AND LOOKED EXACTLY LIKE THE PICTURE ON YOUR WEB SITE WHERE IT'S OPEN ALL AROUND THE FAN HOUSING.     ISN'T THAT A SHAME THAT A CONTRACTOR WOULD DO SUCH SLOPPY WORK.     I DIDN'T USE THESE SAME CONTRACTORS AND WOULDN'T RECOMMEND THEM TO ANY ONE.    THE NEW CONTRACTOR DID A WONDERFUL JOB.

    YES, SO FAR THE NEW FAN IS QUIET AND I'M GLAD IT'S IN BEFORE THE HEAT OF THE SUMMER FORBIDS ONE FROM ENTERING THE ATTIC TO INSTALL ONE.   HOPEFULLY THE 12" FAN WILL DO THE JOB AS YOU TALKED ME OUT OF THE 14" FAN SAYING I WOULD BE OVER DOING IT.    THE OLD FAN WAS ONE YEAR OLD AND WAS------"WHISPERCOOL" ATTIC VENTILATOR 1320 CFM, MODEL # 53319  WCGB  12"------AND THE MOTOR WAS SHOT AND WOULDN'T RUN AT ALL.    HOPEFULLY THE NEW FAN THAT I PURCHASED FROM YOU WILL LAST MUCH LONGER AS IT'S QUITE EXPENSIVE ON SOCIAL SECURITY MONEY.   

 THANKS FOR ALL YOUR TIME AND THE VALUABLE INFORMATION.-----------------------------MARVIN


   My purchase of an attic vent fan was a completly good experience. I like your website.....lots of information.   If you could somehow get the price down that would be key to increasing your sales .....until....until..... people "get it"...your product and the packaging it arrived in reminded me very much of the aircraft I worked on....solid, extreme quality, excellent design,  applied correctly to solve a problem........most people will not pay for that....I learned that the long hard way.....very few people will "take a chance" for quality....lots of folks have no clue about saving energy.  Your web site should be read by everyone!

 
regards,
Mark B.

Body: Found this product via web search, met my needs for high-quality attic vent fan. Ordered easily via net; clearly superior product to what was available in local stores. There was slight back-log, nothing significant; I had the product 11 days after order. Company kept me informed of progress. After receipt and installation (using straightforward instuctions), company was prompt in following-up on a few questions. The web information was thorough and very helpful in making my decision to purchase this product. The optional sheet-metal mounting box proved a wise choice.

Body: We did purchase your Thermal Control Membrane (Mylar sheet stuff) and an attic fan and we couldnt be happier. The fan was amazingly easy to install and works like a charm, though I couldnt give any stats yet as summer isnt quite here in AZ. I think it will make a huge difference in keeping the attic cool and thus allowing the HVAC air handler up there to work more efficiently. The film was also very interesting and on the day I put it up (afternoon on a west wall) I could literally feel the difference on a section where I installed it versus a section where I didnt and it made a huge difference to the heat coming through the wall. All in all, we are very happy with your products as well as customer service and I really think the combination of the attic fan and reflective film will make a good dent in keeping our house energy efficient.

Title:
Body: I recently purchased a 14 attic gable fan from Horizon Energy Systems. I researched fans and knew I wanted a high quality fan with a good guarantee. Horizon Energy Systems sells such a fan. I was informed that the fan was temporarily out of stock, but I was given a date the fan would be in stock and when it would ship to me. I received confirmation of the stated shipping date and was given a tracking number. The fan arrived when I was told it would. The order was complete and in good condition when received. Customer service was outstanding. Because I was promptly informed of the out-of-stock status I decided to wait (approximately one week) to get the fan I wanted. I have not regretted that decision. I would recommend Horizon Energy Systems to anyone looking to purchase quality merchandise from a seller who kept me informed of the order status every step of the way. If only other sellers were this good.
