Love these. Sell them often especially older homes where limited intake is present or likely plugged. Deck air intake vents can be installed on the roof to replace soffit intake. Turbines work very well for moving air with no electrical work.
Thank you for sharing your recommendation of Lomanco Deck air intake vents and Lomanco Turbines. It's great to hear that they work well for improving air circulation in homes with limited intake or plugged soffit intake. The fact that the turbines work without electrical work is also a convenient feature. It's always good to have options that can be easily installed and improve the efficiency of a home's ventilation system.
I'm glad to hear that Doug was able to assist you in finding the name of what you were looking for. If you have any other questions or need further assistance, feel free to ask!
Agree with the intake. I guess the intake and exhaust placement is the key, right? If the intake is only 1 right below the exhaust, wouldn't the air not blow the smoke out? Like just enter and out? Then what if the intake is a hole in the ceiling? So, the air enters thru windows (or any vents in the house). Then the house will possibly get fresh air every time? What do you think?
Turbines will work at maximum efficiency when the top of the turbine is over the ridge line. When installed at the peak of the roof, turbines will be exposed to the wind from all directions. On most pitched roofs, you will want to cut the hole about 18 - 24 inches from the peak of the roof. it's okay to add ventilation to your existing system. However, only add the SAME TYPE OF EXHAUST ventilation as your home currently has installed - do not mix exhaust products on the same common attic space. If Whirlybirds® exists, add Whirlybirds®, if roof louvers exist, add roof louvers. Keep in mind you want to install all exhaust ventilation at the SAME HEIGHT within a common attic area. Also, do not overlook the intake part of the system. A BALANCED SYSTEM must have 50% exhaust and 50% intake. If you add exhaust ventilation, make sure you have at least 50% of the ventilation located in the soffit. The distinguishing difference between an intake and exhaust vent is their location on the roof. All exhaust type ventilators are to be installed on the upper 1/3 portion of the attic area. Intake vents are located near the lower part of the attic area. Refer to the specific type of product to determine if it is an intake or exhaust vent.
What would happen if u had too many soffits in the under eaves while installing the whirly birds? Will there be a reverse flow where air goes into the whirley bird and out the soffits?
If an exhaust product is looking for intake and balanced intake is not provided, the exhaust product could use another exhaust product for intake. Therefore, more intake is better. Balanced is best
@@Lomanco which is better the turbine or the ridge vent? I gotta figure out that I might just take out the whirley bird out and patch up the roof. Close the gables. And just leave the soffits and the ridge gent
I put one in yesterday. I’m going to put another one next week. I look around the attic and see spots cleared out where the soffit vents are. I need to bring a ciggarette up there or something to make sure it’s venting like this.
We manufacture 3 sizes of turbines- 8”, 12”, and 14”. The 12" turbine is available in aluminum and galvanized finishes as well as a Tile Roof Design. Whilybrid turbines are also available in two models - internally and externally braced. While the internally and externally braced turbines both have the same internal construction, the externally braced turbines have 3 braces that surround the outside of the turbine. The air being exhausted MUST be replaced by outside air drawn through intake vents located near the lower part of the attic space to properly ventilate the total attic area and eliminate weather infiltration. -Each 8" turbine requires 138 square inches of intake ventilation -Each 12” turbine requires 259 square inches of intake ventilation -Each 14” turbine requires 345 square inches of intake ventilation Download Lomanco Vent Selector App for the iPhone or Android.
I've been wondering. Which is better between Duraflow Turbo Pro or the Lomanco Wind Turbine? I've seen the wind and rain mock test videos between these two vents but I had the feeling they put up a lower quality of whirly birds. Duraflow Turbo Pro is a static vent with baffle system and the whirly bird is a wind driven turbine to pump air out of the attic. So by design and performance which is a better vent?
I'm curious about that as well. I've heard that the Turbo Pro is better at keeping water out and no moving parts so no chance of squeeks or failed bearings. I would think the wirlybird would possibly move more air, but there's talk that with cost being such a big factor with consumers, manufacturers are cutting corners by using inferior materials which may lead to possible squeeks or bearing failure.
The Lomanco Whirlybird turbine vent functions as effectively as a static vent when it's not spinning. However, with just a slight breeze, the Whirlybird transforms into a wind pump, significantly increasing its ventilation capacity. Additionally, the Whirlybird has been on the market for many years, with a proven track record, and comes with a Forever Guarantee.
When turbines are properly installed with a balanced system of intake and exhaust, they should not allow any weather infiltration. The turbine has twenty-one (21) air-foil curved vanes with rolled edges to deflect water. The rolled edges are designed to force the water to run down the vanes & not into the attic. Air-foil means a body designed to provide a desired reaction force when in motion relative to the surrounding area. To summarize, the turbine should be turning at all times when there is outside air movement. The centrifugal force of the turbine also prevents leakage. Centrifugal force is the force that tends to impel a thing or parts of a thing, such as rain, outward from a center of rotation, such as the bearing/shaft assembly in the turbine. It is important that the unit be sealed with roofing cement around all seams, nails, and under the flashing. The part of the flashing that is facing the roof peak should be installed underneath the shingles and the bottom part should be overlapping the shingles. Sealing in this manner prevents water from entering the attic under the flashing.
Then that defeat the whole process of the Fan working on remove water attic . When it raining the fan move channels water away from the fan , my grandfather and I have been removing all electric power fan because of the old motor has quick working and didn't remove hot and cold air out of the attic so we replaced it with whirlybirds fan because it requires no motor . Even during the power outage .

This house I'm in now has no attic ventilation and it's a 45-year-old house! WTF? I'm very concerned about cooling bills this summer. I want to add attic ventilation but I don't particularly want all the cold air rushing through the attic in the winter. I know I can cover the whirlybird in the winter but how do you close the inlet vents in the winter? I know that theoretically it is supposed to be vented year-round but as an older house it's not insulated very well and it's so arid here I'm not concerned with mold or mildew.
In cold climates with snow it is important that the attic is well ventilated during winter so that the snow doesn't melt and cause an ice dam that in turn can cause the roof to leak. Also closing off an attic can cause mold and mildew build up through out the seasons so air flow is important for all attics. Try searching for attic ventilation designs suitable for your climate to better refine what would suit you. Some old traditional houses in tropical climates are open construction with limited seals so there is no need to worry about ventilation as the house exchanges air naturally, this style is difficult to add heat and air-conditioning.
Properly functioning attic ventilation systems are required year around. Most people associate attic ventilation with heat; however, of the two major destructive forces at work in your attic, moisture, not heat, is the most destructive. Since winter air is drier, it absorbs moisture from your home and you. The attic space is even more susceptible to excessive moisture in the winter. Plus when air is trapped inside the attic - it will always be warmer than the air outside. The roof sheathing/decking will be colder in winter months. Thus creating even more condensation. It can literally "rain" in your attic. This moisture produces mildew, rotting conditions damaging wood members and destroying shingles or it drips down to the ceiling below to damage plaster or paint. Insulation also becomes wet and provides less resistance to heat loss - in effect loses its R-value.
I would be glad to explain. Thanks for asking. When a soffit is blocked, it can restrict the airflow into the attic space. This restriction can affect the proper functioning of ventilation systems like whirlybirds. Whirlybirds, also known as turbine vents or roof vents, are designed to create natural ventilation by utilizing wind energy. To understand why hot air may not escape through a whirlybird when the soffit is blocked, we need to consider the airflow dynamics in the attic. 1. Intake vents: Soffit vents or other intake vents are responsible for bringing in fresh air from outside into the attic space. These vents are typically located along the eaves of the roof or in the soffit area. The incoming air replaces the hot air in the attic, maintaining proper ventilation. 2. Exhaust vents: Whirlybirds or other exhaust vents are installed on the roof's ridgeline. They are designed to expel the hot air that accumulates in the attic. As the wind blows, it creates a pressure difference between the inside and outside of the whirlybird, causing it to spin. This spinning motion pulls the hot air out of the attic. When the soffit vents are blocked, the intake of fresh air into the attic is significantly reduced or completely hindered. As a result, there is less cool air available to replace the hot air inside the attic. With limited fresh air intake, the whirlybird has less air to exhaust, reducing its effectiveness in removing the hot air. In this situation, the hot air inside the attic may become trapped and unable to escape efficiently. The lack of proper airflow can lead to increased heat buildup, moisture accumulation, and potential damage to the attic and roof structure. It can also impact the overall energy efficiency of the house, as the hot air trapped in the attic can radiate down into the living space, increasing cooling costs. Therefore, it is crucial to ensure that both intake vents (such as soffit vents) and exhaust vents (like whirlybirds) are unobstructed and properly installed to maintain a balanced and effective ventilation system in the attic.
how much can this save your on your electrical bill? If my bill is coming out to $300 a month and then i install 2 of these in my roof, what will my bill look like? more or less?
Ventilation is needed year round to fight the enemies of heat and moisture. Heat in attics without ventilation may cause temperatures to exceed 150 degrees and cause damage to shingles, roof sheathing, and possible radiate into the living area. Moisture is a home's #1 enemy and can cause rot, mildew, mold, paint blisters, and renders the insulation to be ineffective. Proper Ventilation reduces energy bills, winter ice build up, and eliminates mold / mildew which can lead to major health problems. By ventilating, you are extending the life of shingles, insulation, and other building components.

I have an indoor fireplace chimney stack that is unfortunately lower than roof height and does not draw up smoke. Will a whirlybird solve this problem please?
Ace Hardware and Miller True Value Hardware store, Home Depot has metal Cone shape with a metal screen meshed prevent any birds and insect entering the Chimney Vent cone shaped stainless steel . They make indoor fireplace fan runs on heated up motor remove smoke up to the chimney . I have one hook up to my wood burning stove my is electric fan . But I prefer heat power fan .
There are two things you can do. 1) extend the chimney by adding just a flu tile. Surely the chimney is very close to the top of the ridge so you won't have to go super high. Fortunately for me I was able to remove the existing last chimney tile that extended down about 8 in. Then I added a much longer chimney tile that did the job. 2) You can add a chimney accessory that helps with draw. It is a metal top that spins like a weather vane. It looks like a conquistador's helmet. This always ensures that the exhaust is pointing down wind thus any wind passing over it creates a vacuum. A couple things to note is that you can try to heat up your flu by burning a loosely packed newspaper held up higher. This can warm up the flu and start a little bit of draw. Another thing to note is that you should have a minimum of 7 inches between the top of the opening of the fireplace and the beginning of the damper. Besides having correct fireplace geometry, you need to be able to have that distance to help the smoke begin to "roll" without spilling out the front of your fireplace.
Gentleman..I understood what you explained. When ventilator spins, it throws air outside due to centrifugal action and creats low pressure area below the fan and this creats current of air from inside the shed to outside and it works. But, make me understand one thing that what makes ventilator to spin? If it is outside air then air will surely enters inside the ventilator and not allowing to create low pressure area below Ventillator and thus there will be no air transfer from inside to outside. Can you repeat you experiment and show smoke coming out by keeping whole syatem outside in the breeze and let ventilator spin by natural air? I think it will not expell smoke in that case.
Properly installed turbines should be spinning with minimum wind speed. Every turbine is tested to spin at a wind speed of 3 MPH before leaving our manufacturing facility. There are several factors that influence the the efficiency of a turbine. Turbines will work at maximum efficiency when the top of the turbine is over the roof peak. This will allow the wind to hit the turbine for all directions. The turbine also needs intake vents with an obstructed path to the turbines. Without intake vents, the turbines do not have a continuous flow of make up air. Mixing exhaust products will also have an adverse effect on the turbine. When multiple types of exhaust products are used, the chimney / stack effect is negated and the turbine does not draw from the intake as well.
@@Lomanco so no, you can't.... when was the last time you experienced just a 3 mph wind? xD Don't forget to oil those adamantium bearings with your most expensive very special snake oil..."as seen on TV"
Also the rising motion of heat through the bird will also cause them to spin. Hot summer days with no wind in Australia you can see them spinning fairly quickly
@@dushk0 Bearings are actually vibranium and do not require snake oil. This is why ONLY the Lomanco Whirlybird is guaranteed forever. ) LOL While the "vibranium part is not true, the Forever Guarantee is - media.lomancovents.com/all_access/sales_literature/turbine-forever-guarantee.pdf.

Actually there's a Attic electric power fan in the hallway ceilings that near the return air filter upward to the attic from the bedroom and kitchen and others rooms drawing recirculating from the air conditioning and heating pump outside and inside the house then out into the attic . Every 3 bedrooms house 1000 square feet house has to have 1 whiry fan or 2 fan and 3 to 6 bedrooms house 2000 to 4000 square feet house needs 2 to 4 fans in the attic . It's works great 👍 for me and my family
Thank you for the video of the whirlwind fan whirlybirds sorry I meant . Dumb people covering up whirlybirds fan doesn't work I seen it during the winter they ended up having mold in the attic and hallway ceilings .
Hello Ajay! It's great to hear from you. The whirlybird turbine vent and the tulip wind turbine serve different purposes, so they have different functionalities. Whirlybird turbine vents, also known as roof ventilators, are designed to provide ventilation for buildings by extracting hot air and moisture from the attic or enclosed spaces. They work by utilizing wind power to spin the turbine, creating a suction effect that draws out the air. On the other hand, tulip wind turbines, or wind turbines in general, are specifically designed to generate electricity from wind energy. They consist of multiple large blades that capture the kinetic energy of the wind and convert it into electrical energy through a generator. While both systems involve the utilization of wind power, the primary purpose of a whirlybird turbine vent is ventilation, not electricity generation. The design, size, and efficiency of a roof ventilator are optimized for air movement, rather than maximizing electricity production. If your goal is to produce electricity, I would recommend exploring dedicated wind turbines designed for that purpose, such as small-scale residential wind turbines or larger wind farms, depending on your requirements. These systems are specifically engineered to efficiently convert wind energy into electrical power. Feel free to ask if you have any further questions or need more information!
Lomanco Whirlybird turbines are expressly designed for residential attic air ventilation. Any usage outside of this specific purpose is strongly discouraged by Lomanco and will result in the automatic voiding of all warranties. It is imperative to adhere to the intended use to ensure optimal performance and maintain warranty coverage.

Yes, it is still important to insulate even if you have roof vents. In fact, insulation and roof ventilation work together to create an energy-efficient and healthy home. Insulation helps to keep the warm air inside during the winter months and prevents hot air from entering your home during summer. This can help reduce your energy bills and keep your home more comfortable throughout the year. Roof vents, on the other hand, allow air to circulate through your attic or roof space, which can help prevent moisture buildup and reduce the risk of mold and other moisture-related problems. This can also help to prolong the life of your roof by reducing the risk of rot and other damage. Therefore, it's important to ensure that your attic or roof space is properly insulated, even if you have roof vents installed. This can help to create a more energy-efficient and healthy home environment.
Yes but, when multiple types of exhaust products are used, the chimney / stack effect is negated and the turbine does not draw from the intake as well. Without intake vents, the turbines do not have a continuous flow of make up air
Intake is very important to the ventilation system. Unfortunately, intake is often overlooked. In fact, inadequate intake is the number one reason for failure of an attic ventilation system. Lack of intake vents results in extreme heat buildup in the summer and severe moisture problems in the winter. Additionally, exhaust vents can actually become intake vents if no intake vents are present and pull in rain and snow. You must have a continuous supply of fresh air to “feed” the exhaust vents. The intake system must provide as much or more than the exhaust system in net free area. Lomanco offers a full line of intake vents to meet your needs.
Just a vent for incoming air - basically an insulated duct with a grille, a hole in a wall, so that the real vent in your kitchen doesn't make this tinfoil miracle rattle or spin backwards xD
sheds don't need roof vents so long as the door isn't sealed (air tight) if you live in a area with in direct sun and high temps then a gable vent would be best (less roof penetrations the better)
In Malaysia, the roof design of majority house in this country are closed type where there is no intake.And i see so many people install this at the rooftop.after seeing this video, i think they do useless thing.😅
Looks to me like its rigged somehow? Should have a fan, blowing on the whirlie bird to make it spin, since I'm not going to climb up and spin it every time there's smoke in my attic.
The wind moves these Whirlybird's, out in the real world. As air is invisible, the smoke is only used to show this air flow, from the soffits, and out the Whirlybird. Doug shows what happens to this flow if the soffits are blocked. You will get a natural flow due to heat rising but the Whirlybird "speeds" this flow up. Dominus Vobiscum

These are only good if you have too much stack effect and you need to tame it. You can insert a reduction or a basic "hat", those won't rattle in every storm after 1 winter, at least...
I appreciate your feedback and the humor! While the turbine size would remain the same as demonstrated in our demo, you would likely need more than one for your roof. To figure out the exact number required for optimal ventilation, you can conveniently use our Vent Selector app or the online calculator available on our website. They are great tools to ensure you get just the right setup for your needs. Let me know if you need any assistance with these tools!

Not really an honest representation when the air volume in the whiry fan is half the size of the attic, then you spin it by hand with the force of a 40 mph wind. If you have that much wind I'll bet a gable end vent is as good if not more effective
He use cheat to advertise, it dont spin that fast on normal weather condition specially during summer when theres no air blowing that makes the heat very bad. So it wont spin and its not that very effective. The purpose is to have a vent where trap air can release.
Lomanco ridge vents are considered one of the best ridge vents for several reasons: 1. Design: Lomanco ridge vents are designed to maximize ventilation by allowing air to flow in and out of the attic space. The vent's design features a low profile that blends well with the roofline and a weather-resistant design that keeps out rain, snow, and other outdoor elements. 2. Durability: Lomanco ridge vents are made with high-quality materials that are designed to last for many years. They are constructed with a durable aluminum or Custom blended, high impact co-polymer with UV stabilization additives, that can withstand harsh weather conditions. 3. Performance: Lomanco ridge vents are designed to provide superior ventilation performance, which helps to reduce moisture buildup, prevent mold growth, and extend the life of the roof. They have create maximum airflow, which allows for maximum ventilation, and they are compatible with a wide range of roof types and pitches. 4. Warranty: Lomanco offers a limited lifetime warranty on their ridge vents, which demonstrates their confidence in the quality and durability of their product. Overall, Lomanco ridge vents are a popular choice among homeowners and contractors for their high performance, durability, and compatibility with various roofing types.
The summer nights here were horrible and this brought much needed relief
I presume that you were also in Texas this summer. 😒🌞

Good deal.
thx
can we generate electricity out of it? just curious. could you please give your opinion?
when I was a kid I always wondered what those spinning thingies are on rooftops
How do we know where to locate the turbines to make sure they are most effective? There are gables vents but im not sure where to put the turbines.
Turbines will work at maximum efficiency when the top of the turbine is over the ridge line. When installed at the peak of the roof, turbines will be exposed to the wind from all directions. On most pitched roofs, you will want to cut the hole about 18 - 24 inches from the peak of the roof.
it's okay to add ventilation to your existing system. However, only add the SAME TYPE OF EXHAUST ventilation as your home currently has installed - do not mix exhaust products on the same common attic space. If Whirlybirds® exists, add Whirlybirds®, if roof louvers exist, add roof louvers.
Keep in mind you want to install all exhaust ventilation at the SAME HEIGHT within a common attic area.
Also, do not overlook the intake part of the system. A BALANCED SYSTEM must have 50% exhaust and 50% intake. If you add exhaust ventilation, make sure you have at least 50% of the ventilation located in the soffit.
The distinguishing difference between an intake and exhaust vent is their location on the roof. All exhaust type ventilators are to be installed on the upper 1/3 portion of the attic area. Intake vents are located near the lower part of the attic area. Refer to the specific type of product to determine if it is an intake or exhaust vent.
What would happen if u had too many soffits in the under eaves while installing the whirly birds? Will there be a reverse flow where air goes into the whirley bird and out the soffits?
If an exhaust product is looking for intake and balanced intake is not provided, the exhaust product could use another exhaust product for intake.
Therefore, more intake is better. Balanced is best
@@Lomanco thank u so much!!!
@@Lomanco which is better the turbine or the ridge vent? I gotta figure out that I might just take out the whirley bird out and patch up the roof. Close the gables. And just leave the soffits and the ridge gent

Be careful, smoking in the attic. lol
I see so many of these in factories
There is only one Lomanco Whirlybird® turbine vent.
What are the sizes available for this product? What is the coverage area of each available size? example 300mm unit = 50 square meters.... Thanks
We manufacture 3 sizes of turbines- 8”, 12”, and 14”.
The 12" turbine is available in aluminum and galvanized finishes as well as a Tile Roof Design. Whilybrid turbines are also available in two models - internally and externally braced. While the internally and externally braced turbines both have the same internal construction, the externally braced turbines have 3 braces that surround the outside of the turbine.
The air being exhausted MUST be replaced by outside air drawn through intake vents located near the lower part of the attic space to properly ventilate the total attic area and eliminate weather infiltration.
-Each 8" turbine requires 138 square inches of intake ventilation
-Each 12” turbine requires 259 square inches of intake ventilation
-Each 14” turbine requires 345 square inches of intake ventilation

I've seen the wind and rain mock test videos between these two vents but I had the feeling they put up a lower quality of whirly birds. Duraflow Turbo Pro is a static vent with baffle system and the whirly bird is a wind driven turbine to pump air out of the attic. So by design and performance which is a better vent?
I'm curious about that as well. I've heard that the Turbo Pro is better at keeping water out and no moving parts so no chance of squeeks or failed bearings. I would think the wirlybird would possibly move more air, but there's talk that with cost being such a big factor with consumers, manufacturers are cutting corners by using inferior materials which may lead to possible squeeks or bearing failure.
The Lomanco Whirlybird turbine vent functions as effectively as a static vent when it's not spinning. However, with just a slight breeze, the Whirlybird transforms into a wind pump, significantly increasing its ventilation capacity. Additionally, the Whirlybird has been on the market for many years, with a proven track record, and comes with a Forever Guarantee.
In a driving rain will rain get inside that vent and cause water damage below in side the attic?
When turbines are properly installed with a balanced system of intake and exhaust, they should not allow any weather infiltration.
The turbine has twenty-one (21) air-foil curved vanes with rolled edges to deflect water. The rolled edges are designed to force the water to run down the vanes & not into the attic. Air-foil means a body designed to provide a desired reaction force when in motion relative to the surrounding area. To summarize, the turbine should be turning at all times when there is outside air movement.
The centrifugal force of the turbine also prevents leakage. Centrifugal force is the force that tends to impel a thing or parts of a thing, such as rain, outward from a center of rotation, such as the bearing/shaft assembly in the turbine.
It is important that the unit be sealed with roofing cement around all seams, nails, and under the flashing. The part of the flashing that is facing the roof peak should be installed underneath the shingles and the bottom part should be overlapping the shingles. Sealing in this manner prevents water from entering the attic under the flashing.
If there is a water leaking from whirlybird during raining, how to fix it.
@Rip Steele hahaha that's the first solution i have done.
Then that defeat the whole process of the Fan working on remove water attic . When it raining the fan move channels water away from the fan , my grandfather and I have been removing all electric power fan because of the old motor has quick working and didn't remove hot and cold air out of the attic so we replaced it with whirlybirds fan because it requires no motor . Even during the power outage .
It works for camping shell on truck and trailer

This house I'm in now has no attic ventilation and it's a 45-year-old house!
WTF?
I'm very concerned about cooling bills this summer.
I want to add attic ventilation but I don't particularly want all the cold air rushing through the attic in the winter. I know I can cover the whirlybird in the winter but how do you close the inlet vents in the winter?
I know that theoretically it is supposed to be vented year-round but as an older house it's not insulated very well and it's so arid here I'm not concerned with mold or mildew.
In cold climates with snow it is important that the attic is well ventilated during winter so that the snow doesn't melt and cause an ice dam that in turn can cause the roof to leak. Also closing off an attic can cause mold and mildew build up through out the seasons so air flow is important for all attics. Try searching for attic ventilation designs suitable for your climate to better refine what would suit you. Some old traditional houses in tropical climates are open construction with limited seals so there is no need to worry about ventilation as the house exchanges air naturally, this style is difficult to add heat and air-conditioning.
Properly functioning attic ventilation systems are required year around.
Most people associate attic ventilation with heat; however, of the two major destructive forces at work in your attic, moisture, not heat, is the most destructive. Since winter air is drier, it absorbs moisture from your home and you.
The attic space is even more susceptible to excessive moisture in the winter. Plus when air is trapped inside the attic - it will always be warmer than the air outside. The roof sheathing/decking will be colder in winter months. Thus creating even more condensation. It can literally "rain" in your attic. This moisture produces mildew, rotting conditions damaging wood members and destroying shingles or it drips down to the ceiling below to damage plaster or paint. Insulation also becomes wet and provides less resistance to heat loss - in effect loses its R-value.
Pls explain why hot air will not escape thru the whirlybird when soffit is blocked.
I would be glad to explain. Thanks for asking.
When a soffit is blocked, it can restrict the airflow into the attic space. This restriction can affect the proper functioning of ventilation systems like whirlybirds. Whirlybirds, also known as turbine vents or roof vents, are designed to create natural ventilation by utilizing wind energy.
To understand why hot air may not escape through a whirlybird when the soffit is blocked, we need to consider the airflow dynamics in the attic.
1. Intake vents: Soffit vents or other intake vents are responsible for bringing in fresh air from outside into the attic space. These vents are typically located along the eaves of the roof or in the soffit area. The incoming air replaces the hot air in the attic, maintaining proper ventilation.
2. Exhaust vents: Whirlybirds or other exhaust vents are installed on the roof's ridgeline. They are designed to expel the hot air that accumulates in the attic. As the wind blows, it creates a pressure difference between the inside and outside of the whirlybird, causing it to spin. This spinning motion pulls the hot air out of the attic.
When the soffit vents are blocked, the intake of fresh air into the attic is significantly reduced or completely hindered. As a result, there is less cool air available to replace the hot air inside the attic. With limited fresh air intake, the whirlybird has less air to exhaust, reducing its effectiveness in removing the hot air.
In this situation, the hot air inside the attic may become trapped and unable to escape efficiently. The lack of proper airflow can lead to increased heat buildup, moisture accumulation, and potential damage to the attic and roof structure. It can also impact the overall energy efficiency of the house, as the hot air trapped in the attic can radiate down into the living space, increasing cooling costs.
Therefore, it is crucial to ensure that both intake vents (such as soffit vents) and exhaust vents (like whirlybirds) are unobstructed and properly installed to maintain a balanced and effective ventilation system in the attic.
This works with gable vent?
What is the recommendation amount of whirly bird to install on your roof?
As many as you can fit, of course!
@@dushk0 🤣😂🤣
Depends on the size of your roof….. 2 for a regular size roof should do
Please use our Vent Selector app. Available for iPhone and Android devices.
@@Lomanco I'll look for it.
how much can this save your on your electrical bill? If my bill is coming out to $300 a month and then i install 2 of these in my roof, what will my bill look like? more or less?
Ventilation is needed year round to fight the enemies of heat and moisture. Heat in attics without ventilation may cause temperatures to exceed 150 degrees and cause damage to shingles, roof sheathing, and possible radiate into the living area. Moisture is a home's #1 enemy and can cause rot, mildew, mold, paint blisters, and renders the insulation to be ineffective.
Proper Ventilation reduces energy bills, winter ice build up, and eliminates mold / mildew which can lead to major health problems. By ventilating, you are extending the life of shingles, insulation, and other building components.
Does rain water come inside through this? someone please advise. Thank you!

To the point
No vain empty or extra nonsense
Thanks
I have an indoor fireplace chimney stack that is unfortunately lower than roof height and does not draw up smoke. Will a whirlybird solve this problem please?
The Lomanco Whirlybird® turbine is not designed for use on any fireplace chimney.
Ace Hardware and Miller True Value Hardware store, Home Depot has metal Cone shape with a metal screen meshed prevent any birds and insect entering the Chimney Vent cone shaped stainless steel . They make indoor fireplace fan runs on heated up motor remove smoke up to the chimney . I have one hook up to my wood burning stove my is electric fan . But I prefer heat power fan .
BASS Pro Shop and any camping fishing department has a tent wood burning stove with a built-in vent tubing protect tent from burning down .
There are two things you can do.
1) extend the chimney by adding just a flu tile. Surely the chimney is very close to the top of the ridge so you won't have to go super high. Fortunately for me I was able to remove the existing last chimney tile that extended down about 8 in. Then I added a much longer chimney tile that did the job.
2) You can add a chimney accessory that helps with draw. It is a metal top that spins like a weather vane. It looks like a conquistador's helmet. This always ensures that the exhaust is pointing down wind thus any wind passing over it creates a vacuum.
A couple things to note is that you can try to heat up your flu by burning a loosely packed newspaper held up higher. This can warm up the flu and start a little bit of draw.
Another thing to note is that you should have a minimum of 7 inches between the top of the opening of the fireplace and the beginning of the damper. Besides having correct fireplace geometry, you need to be able to have that distance to help the smoke begin to "roll" without spilling out the front of your fireplace.
Gentleman..I understood what you explained. When ventilator spins, it throws air outside due to centrifugal action and creats low pressure area below the fan and this creats current of air from inside the shed to outside and it works. But,
make me understand one thing that what makes ventilator to spin? If it is outside air then air will surely enters inside the ventilator and not allowing to create low pressure area below Ventillator and thus there will be no air transfer from inside to outside.
Can you repeat you experiment and show smoke coming out by keeping whole syatem outside in the breeze and let ventilator spin by natural air? I think it will not expell smoke in that case.
Properly installed turbines should be spinning with minimum wind speed. Every turbine is tested to spin at a wind speed of 3 MPH before leaving our manufacturing facility.
There are several factors that influence the the efficiency of a turbine. Turbines will work at maximum efficiency when the top of the turbine is over the roof peak. This will allow the wind to hit the turbine for all directions. The turbine also needs intake vents with an obstructed path to the turbines. Without intake vents, the turbines do not have a continuous flow of make up air. Mixing exhaust products will also have an adverse effect on the turbine. When multiple types of exhaust products are used, the chimney / stack effect is negated and the turbine does not draw from the intake as well.
Anand Lashkari hopefully that answered your question
@@Lomanco so no, you can't.... when was the last time you experienced just a 3 mph wind? xD Don't forget to oil those adamantium bearings with your most expensive very special snake oil..."as seen on TV"
Also the rising motion of heat through the bird will also cause them to spin. Hot summer days with no wind in Australia you can see them spinning fairly quickly
@@dushk0 Bearings are actually vibranium and do not require snake oil. This is why ONLY the Lomanco Whirlybird is guaranteed forever. ) LOL While the "vibranium part is not true, the Forever Guarantee is - media.lomancovents.com/all_access/sales_literature/turbine-forever-guarantee.pdf. Have a good day, my friend.

If the window is all closed.. but turn on ceiling fan in all room.. can it create air intake?
Intake air needs to come for outside of the home.
Actually there's a Attic electric power fan in the hallway ceilings that near the return air filter upward to the attic from the bedroom and kitchen and others rooms drawing recirculating from the air conditioning and heating pump outside and inside the house then out into the attic . Every 3 bedrooms house 1000 square feet house has to have 1 whiry fan or 2 fan and 3 to 6 bedrooms house 2000 to 4000 square feet house needs 2 to 4 fans in the attic . It's works great 👍 for me and my family
Thank you for the video of the whirlwind fan whirlybirds sorry I meant . Dumb people covering up whirlybirds fan doesn't work I seen it during the winter they ended up having mold in the attic and hallway ceilings .
This is to vent your attic - not your living space.
Hi
This is Ajay from India
Can we use this machanism for produce electricity like tulip wind turbine.
Kindly reply
Hello Ajay! It's great to hear from you. The whirlybird turbine vent and the tulip wind turbine serve different purposes, so they have different functionalities.
Whirlybird turbine vents, also known as roof ventilators, are designed to provide ventilation for buildings by extracting hot air and moisture from the attic or enclosed spaces. They work by utilizing wind power to spin the turbine, creating a suction effect that draws out the air.
On the other hand, tulip wind turbines, or wind turbines in general, are specifically designed to generate electricity from wind energy. They consist of multiple large blades that capture the kinetic energy of the wind and convert it into electrical energy through a generator.
While both systems involve the utilization of wind power, the primary purpose of a whirlybird turbine vent is ventilation, not electricity generation. The design, size, and efficiency of a roof ventilator are optimized for air movement, rather than maximizing electricity production.
If your goal is to produce electricity, I would recommend exploring dedicated wind turbines designed for that purpose, such as small-scale residential wind turbines or larger wind farms, depending on your requirements. These systems are specifically engineered to efficiently convert wind energy into electrical power.
Feel free to ask if you have any further questions or need more information!
Are wind turbines spark proof? I'm thinking of doing a VMS system to vent Methane.
Lomanco Whirlybird turbines are expressly designed for residential attic air ventilation. Any usage outside of this specific purpose is strongly discouraged by Lomanco and will result in the automatic voiding of all warranties. It is imperative to adhere to the intended use to ensure optimal performance and maintain warranty coverage.
@@Lomanco Thank you.

is that a ridge vent as well?
Do you still need to insulate if you have roof vents?
Yes, it is still important to insulate even if you have roof vents. In fact, insulation and roof ventilation work together to create an energy-efficient and healthy home.
Insulation helps to keep the warm air inside during the winter months and prevents hot air from entering your home during summer. This can help reduce your energy bills and keep your home more comfortable throughout the year.
Roof vents, on the other hand, allow air to circulate through your attic or roof space, which can help prevent moisture buildup and reduce the risk of mold and other moisture-related problems. This can also help to prolong the life of your roof by reducing the risk of rot and other damage.
Therefore, it's important to ensure that your attic or roof space is properly insulated, even if you have roof vents installed. This can help to create a more energy-efficient and healthy home environment.
is electricallt powered?
the attic space to turbine ratio is way off so it wouldn't work that dramatically at proper scale. But it demonstrates the principle.
Yes, this is a dramatization to demonstrate the function of a turbine ventilator.
Does those spin just from the heat of the attic?
The wind moves these Whirlybird's
Yes but, when multiple types of exhaust products are used, the chimney / stack effect is negated and the turbine does not draw from the intake as well. Without intake vents, the turbines do not have a continuous flow of make up air
👍
will it matter if the intake is a small one?
The ventilation system needs to be 50% intake and 50% exhaust.
How to do an intake?
Intake is very important to the ventilation system. Unfortunately, intake is often overlooked. In fact, inadequate intake is the number one reason for failure of an attic ventilation system. Lack of intake vents results in extreme heat buildup in the summer and severe moisture problems in the winter. Additionally, exhaust vents can actually become intake vents if no intake vents are present and pull in rain and snow. You must have a continuous supply of fresh air to “feed” the exhaust vents. The intake system must provide as much or more than the exhaust system in net free area. Lomanco offers a full line of intake vents to meet your needs.
Just a vent for incoming air - basically an insulated duct with a grille, a hole in a wall, so that the real vent in your kitchen doesn't make this tinfoil miracle rattle or spin backwards xD
Is that power operated? Like does that have any electric motor?
No. It's wind powered because it's supposed to be put on the roof of your house where it's windy, it'll spin faster depending on wind
with a shed type roof without a ceiling, does it require a roof ventilation. kindly advise
sheds don't need roof vents so long as the door isn't sealed (air tight) if you live in a area with in direct sun and high temps then a gable vent would be best (less roof penetrations the better)
You would need to check with your local building codes as to what is required in your area.
I would put it on anyway on my shed and garage it gets really hot and cold summer and winter . The more fan take away bad air the better .
Is this for stove and fireplace ??
NO - The Lomanco Whirlybird turbine vent is NOT designed for use to vent a stove or fireplace and doing voids all warranties.
In Malaysia, the roof design of majority house in this country are closed type where there is no intake.And i see so many people install this at the rooftop.after seeing this video, i think they do useless thing.😅
Wonder why we don't see them as much anymore
Don't know - we have more going out the door than ever. Some areas certain types of vents are more popular than others.
builders are cheap
Looks to me like its rigged somehow?
Should have a fan, blowing on the whirlie bird to make it spin, since I'm not going to climb up and spin it every time there's smoke in my attic.
The wind moves these Whirlybird's, out in the real world. As air is invisible, the smoke is only used to show this air flow, from the soffits, and out the Whirlybird. Doug shows what happens to this flow if the soffits are blocked. You will get a natural flow due to heat rising but the Whirlybird "speeds" this flow up. Dominus Vobiscum
If I have a gas fireplace converting to wood burning will the whirlybird exhaust the smoke

These are only good if you have too much stack effect and you need to tame it. You can insert a reduction or a basic "hat", those won't rattle in every storm after 1 winter, at least...
Hahaha 😆......excellent comment 👌
nice, so should i put a turbine with the size of my roof??? LOL use a scale....
I appreciate your feedback and the humor! While the turbine size would remain the same as demonstrated in our demo, you would likely need more than one for your roof. To figure out the exact number required for optimal ventilation, you can conveniently use our Vent Selector app or the online calculator available on our website. They are great tools to ensure you get just the right setup for your needs. Let me know if you need any assistance with these tools!
I been seeing some dumb people covering up the exhausted fan with black bags . Is kinda stupidity in the winter
It what keeps contractors busy. Fixing the idiots mistakes.

Not really an honest representation when the air volume in the whiry fan is half the size of the attic, then you spin it by hand with the force of a 40 mph wind. If you have that much wind I'll bet a gable end vent is as good if not more effective
He use cheat to advertise, it dont spin that fast on normal weather condition specially during summer when theres no air blowing that makes the heat very bad. So it wont spin and its not that very effective. The purpose is to have a vent where trap air can release.
The proportion of roof and turbin isnt real
This is a dramatization aimed at illustrating the fundamental principles of a turbine ventilator's functioning.
Owens Corning RidgeVents are waaayyy better
