Lomanco® Whirlybird® Turbine Smoke House Demo

[@jorggamingcr409]

Im 31yo and I finally learned how this things work! I have seen them since i was a child, most of the time in stores or supermarkets, I thought they introduced fresh air but now I see they pump hot air out (since hot air goes upward) while making easier to cold/fresh air being introduced from the bottom (doors, open windows, etc etc)

[@phs125]

I'm 27yo, and I know a little bit about conservation of energy. But my dad insisted since my highschool days that passive exhaust fans exist, (as in the things you put on a wall of a kitchen etc) I never believed him because if you have a hole in the wall, it's gonna help some smoke get out. But if you put a fan in the way, the surface area of the hole reduces, and also you're adding a job to the air moving out, push the blades along the way. I thought it's impossible. Last month we had a warehouse built and it has two of these things. My dad told me they're passive exhaust fans. And they run without power. I saw with my own eyes that they're rotating without any power supply. I just had to google it. Turns out conservation of energy isn't broken, there's just an additional force acting on it. The wind outside....

[@mysterion4301]

I've installed six of these on three houses either I or family members own over the last two years and love them. They stand up well to both high wind and the moderate rains we get here in California in the milder part of the year; I cover them in winter against heavy rain and to hold in attic heat. The sealed bearings assure that you don't get the squeaking you do in so many other cheaper models out there. A roof angle guage and clear instructions come with each one.

[@Lomanco]

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.

[@Kingboo1081]

This also shows why door vents/grills on bathroom doors are important to help bathroom exhaust fans work properly. Or alternatively, leave the door open a bit. Love this video, I’m going to have these installed in my new house. I rarely see people installing them or talking about them enough, it’s a shame!! Not many people seem too focused on their roof space and the damage that can occur from heat and/or damp that is trapped in there. And people love dark and even black roofs… I certainly won’t be having a dark coloured roof! There’s enough evidence to show dark roofs are hotter and don’t reflect the sun, it’s common sense. Thanks for the good video!

[@Lomanco]

Thank you.

[@CBBC435]

I've had ventilation problems with my hip roof. I'm not convinced a ridge vent is adequate on my hip roof since the ridge is much shorter than what would be on a gable roof. My 60s era home was originally built with these turbine style vents, but the previous owner was talked into a ridge vent when the roof was done. The attic is now broiling in the summer time. Testing the ridge vent, I asked my handyman to hold a flame from a lighter close to the ridge vent opening in the attic. The flame was dead still, not even a flicker. My attic was just broiling. I noticed my neighbor had Whirlybirds installed on her new roof and no matter the conditions outside, breezy or still, hers are always spinning. That tells me air is moving all the time. Now I'm about to get my roof done and I ordered Whirlybirds. I can't wait.

[@Lomanco]

Thank you for sharing your experience! Hip roofs can indeed pose unique ventilation challenges due to their shorter ridge length and more confined attic space compared to gable roofs. While ridge vents work well on many roofs, they may not provide adequate airflow for hip roof designs unless carefully paired with sufficient intake ventilation. Your observation about the performance of Whirlybirds aligns with their key advantage: they actively draw air out of the attic whenever there’s wind, even at low speeds. This constant movement helps prevent the heat buildup you’ve described. Unlike passive ridge vents, turbine vents don’t rely solely on convection; they use wind to enhance airflow, making them a great option for your situation. It’s fantastic that you’ve already ordered Whirlybirds for your new roof. Proper installation, combined with adequate soffit intake vents, will likely transform your attic ventilation and help keep your home cooler in the summer. Let us know how the new system performs!

[@verybad6425]

Do not forget to check the soffit inlets mine was only 1/3 on the turbines outlet areas, I have cut a 12” x 36” inlet area at the entrance ceiling and fitted a grill to draw more air to the attic. I can open the grill and fit a board / block it in the winter to keep the attic warmer during the cold month.

[@googatulus5814]

Thanks Lomanco ! We are thinking of installing multiple wind driven turbine vents very soon - this demo helped a lot indeed!

[@alex-sd]

A neighbor told me as the heat rises, it makes the turbine spin faster. I think that is partially true but the turbine design has more to do with catching the wind to spin it.

[@Lomanco]

You're correct in your understanding. While it's true that rising hot air can contribute to the movement of the turbine, the primary design of the Whirlybird turbine is indeed focused on catching the wind. The turbine's blades are specifically designed to capture even slight breezes, which then cause it to spin. This spinning action creates a vacuum that helps draw hot air and moisture out of the attic. So, while the rising heat may have a minor effect on the turbine's movement, it's really the wind and the efficient design of the turbine that are the key factors in its operation.

[@laurences.3250]

Would just like to know if the rain water will enter inside the turbine? If it does how much water will enter inside the roofing through the turbine blade openings?

[@Lomanco]

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.

[@MyEast123]

My house is townhouses is flat roof, no intake what can I do ?

[@Lomanco]

If your townhouse has a flat roof and no intake vents, you may want to consider installing exhaust vents to allow for proper attic ventilation. The lack of intake vents can result in poor air circulation in your attic, which can lead to a buildup of moisture, heat, and other harmful elements. Exhaust vents can be installed on the roof to allow for hot air and moisture to escape from the attic. Some common types of exhaust vents include ridge vents, turbine vents, and static vents. It's important to choose the right type of vent based on your roof design and the amount of airflow needed. You may also want to consult with a professional roofing contractor to determine the best options for your specific situation. They can assess your roof design and recommend the most effective ventilation system for your home.

[@Lomanco]

Lomanco vents, including the whirlybird turbine series, that are marked or identified with "Miami-Dade Approved" has passed testing and met the requirements for use in the High-Velocity​ Hurricane Zone (HVHZ). These attic vents are tested at wind speeds of 30, 70, 90 and 110 mph while having a rainfall rate of 8.8 inches/hour applied to the test deck and vent. The first three wind speeds are applied for a duration of 15 minutes and the final wind speed of 110 mph is applied for 5 minutes. The testing is performed by a third-party laboratory that must be approved by Miami-Dade County. We also sell hurricane caps for our turbine vents if needed. www.lomanco.com/online-store/Turbine-Accessories-c2514408

[@stupadasso1964]

+Michael Mixon Good question. I live in South Florida and installed 2 of these on my house in 2005. My concern was the same as yours in addition to the potential to stand up to hurricane winds and the possible noise from failed bearings. Did my research and Lomanco has sealed lifetime bearings and I purchased caps in case of hurricanes. My AC used to run from sun up till a couple of hours after sundown non-stop due to the lack of ventilation in my attic during the Summer. My electric bill went from close to $240 per month before installation to $130 after. Best investment I've made. To answer your concern, I've had no driven rain go through it nor have I had any leaks. The hardest part for me is getting on the roof and cutting a hole in your roof. Regardless of any manufacturer you decide to go with, I believe these things are the best way of getting ventilation in a roof at a really low cost.

[@tkmad7470]

What if you only have gable vents?

[@Lomanco]

If your home only has gable vents, these can still be effective for attic ventilation, but their efficiency largely depends on their size and placement, as well as other factors like wind direction and air volume in your attic. Gable vents are installed at the peak of the gable ends and allow air to flow through the attic. In the case of having only gable vents, it's crucial to ensure they are adequately sized for your attic space and are not obstructed by any insulation or other materials. If you're finding that your attic is not being ventilated effectively with just gable vents, you might consider using a different vent type, such as ridge vents or a turbine vents like the Whirlybird, to improve airflow. The ventilation system needs to be 50% intake and 50% exhaust. It's always a good idea to consult with a ventilation expert or roofing professional to determine the best setup for your specific home.

[@jolive7953]

It would be nice if you sold a square base plate designed to span the ridges of a metal roof and slide under the ridge cap without leaving gaps. The six sided base that comes with the BIB-12 works great for a shingled roof, but just don't work with metal roofs without DIY modifications. Your 8" vent comes with a square base. Why not do the same for the 12" models. I called the factory in Arkansas, but no one seemed to have any ideas on how to adapt the base to a corrugated metal roof.

[@Lomanco]

Thank you for the feedback! You raise an excellent point about adapting the BIB-12 base for corrugated metal roofs. While the current hexagonal base is optimized for shingled roofs, we understand that metal roofs often require modifications for a proper seal and fit. Offering a square base for the 12” models, similar to the 8” models, is a great suggestion that could simplify installation and improve compatibility. We’ll make sure to pass your feedback along to our design and product teams for consideration in future updates. In the meantime, working with flashing materials or custom-cutting to fit the corrugations can help bridge the gap, though we know it’s not ideal. Thank you for bringing this to our attention!

Whirlybird® turbine vents are a type of roof ventilation system that use wind to remove hot air and moisture from a building's attic or roof space. They are popular because they can help reduce energy costs and prolong the life of a roof by reducing moisture buildup. If you are interested in purchasing a Whirlybird® turbine vent, you can find them at most home improvement stores, as well as online retailers. When choosing a Whirlybird®, it's important to consider the size and pitch of your roof, as well as the prevailing winds in your area. You may also want to consider the color of the vent to ensure that it blends in with your roof. Installation of a Whirlybird® turbine vent can be a DIY project, but if you are not comfortable working on a roof or do not have the necessary tools, it is recommended that you hire a professional to install the vent for you. Proper installation is crucial for the vent to function properly and provide the intended benefits.

[@blackmass1082]

What if its tilted to one side a little? Can rainwater get in?

[@Lomanco]

If a Lomanco Whirlybird turbine vent is slightly tilted, rainwater is generally not expected to enter, as the vent is designed to prevent water intrusion under normal conditions. However, for optimal performance and protection, the vent should be leveled during installation. A tilted vent might: 1. Compromise the effectiveness of water deflection features. 2. Affect the turbine’s ability to spin freely, reducing ventilation efficiency. If the tilt is noticeable, it’s a good idea to adjust the installation to ensure proper leveling.

[@akiang6219]

Seems all systems or brands depend upon the intake, why didn't everyone talk about their intake part, only the vent part? Are "intake" part of the vents installation?

[@Lomanco]

Intake is a very important requirement for​ the ventilation system. Unfortunately, intake is often overlooked. In fact, inadequate intake is the number one reason for the 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.

You want one TYPE of exhaust vent within a common attic area. Exhaust vents pull air from the easiest intake source. The use of two or more types of exhaust vents such as Power Vents with Roof Vents, Ridge Vents with Gable Vents, or any combination of exhaust louvers can make one of these vents act as intake for the other. Intake air should come from the soffit vent area to properly ventilate the total attic area and eliminate weather infiltration.

[@rhylpancakesph]

is it still effective when the whirlybird and the intake are in the same side?

[@BrotherAfnan]

Okay but not efficient. If you installed at front. Your intake must be at the back to create a better flow and efficiency of the air in-out.

[@Lomanco]

When the Whirlybird turbine vent and the intake vent are on the same side of the roof, it can limit the system’s effectiveness because of how airflow dynamics work: 1. Short-Circuiting Airflow: If the intake and exhaust vents are too close to each other, the Whirlybird might pull air directly from the intake vent instead of from across the attic. This is called “short-circuiting,” and it reduces the ventilation’s ability to expel hot air from the far reaches of the attic. 2. Reduced Cross-Ventilation: Ideally, intake vents (like soffit vents) should be positioned lower on the roof, while exhaust vents (like Whirlybirds) should be higher up to allow a natural upward flow of air, which maximizes ventilation efficiency. To make the system more effective: • Ensure Proper Placement: Place the intake vents at the eaves or lower on the roof, and the Whirlybird at a high point, such as the ridge, to create a proper airflow pathway. • Check the Balance: Make sure you have adequate intake ventilation for the number of Whirlybirds installed. A common recommendation is 1 square foot of intake vent area per 300 square feet of attic space. While having intake and exhaust vents on the same side may not completely eliminate their effectiveness, separating them as much as possible will significantly improve performance.

My roofing contractor suggested having 2 turbines installed just beneath the existing 1500 CFM Power Roof Mount Attic Fan (picture a triangle with a power fan at the top and 2 turbines at the bottom). I'm not sure such a system will work because the turbines will turn into intake vents, instead of exhaust vents, when the electric vent is on. I appreciate your advice asap. Thank you.

[@Lomanco]

Do not mix exhaust vent types. You want one TYPE of exhaust vent within a common attic area. Exhaust vents pull air from the easiest intake source. The use of two or more types of exhaust vents such as Power Vents with Roof Vents, Ridge Vents with Gable Vents, or any combination of exhaust louvers can make one of these vents act as intake for the other. Intake air should come from the soffit vent area to properly ventilate the total attic area and eliminate weather infiltration. Lomanco's 3 Must Do Steps Flyer: media.lomancovents.com/all_access/sales_literature/lo291-three_steps.pdf has additional information on using more than 1 type of exhaust vent.

[@Lomanco]

The concept behind wind turbine vents is that the turning blades will help force air out of the attic. Hot air naturally rises, so if attic air is heated above the ambient air temperature a vent will allow the less dense hot air to escape. 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.

[@Lomanco]

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.

The turbine in the demo was chosen to emphasize its performance, but it’s important to note that the demo is a dramatization. For a real home, you’d want to scale things appropriately based on the size and ventilation needs. You can easily determine the proper number of turbine ventilators and intake vents for a balanced ventilation system using our Vent Selector app or by visiting our website at ventselector.lomanco.com/. This will help ensure your system works efficiently for your specific home.

Will this work against keeping heat in???

[@Lomanco]

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.

What about if there's no wind 😏

[@Lomanco]

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. If the turbine spins when you turn it by hand, but not when the wind is blowing, the bearings are probably worn out. If the bearings have gone out, contact customer service (800.643.5596) for warranty information.

I have recently rescued an injured whirlybird from the side of the road, and I am trying to nurse it back to health. What do I feed him?

[@Lomanco]

Absolutely, let's have some fun with satire: Hey there, rescuer of the injured whirlybird! Your dedication to nursing this inanimate object back to "health" is truly commendable. 😄 First things first, carefully and gently pick up your whirlybird and examine it for any "obvious injuries" like loose bolts or rust. After all, you wouldn't want your little turbine friend to have any mechanical mishaps. Now, when it comes to feeding your whirlybird, it's a bit of a gourmet. Place it near the peak of your roof, where it can soak up all that lovely hot air and moisture. For a well-balanced diet, ensure it gets an equal amount of cool outside air from the lower attic area. Remember, it's all about that perfect temperature mix for your whirlybird to thrive! In all seriousness, your whirlybird will be just fine as long as it's properly installed and maintained. If you have any real questions about it, feel free to ask, and I'll gladly assist you in caring for your home's ventilation. 😄

[@Lomanco]

While it's understandable that you're looking for a solution to improve the air quality in your car, installing a whirlybird turbine vent on the roof may not be the most effective or practical approach. Car ventilation systems are designed to circulate fresh air and eliminate odors efficiently. Here are a few alternatives you can consider: 1. Open the windows: Rolling down the windows while driving allows for better air circulation, which can help dissipate any unpleasant odors. 2. Use air fresheners: Utilize air fresheners specifically designed for cars to help mask any unwanted smells. There are many options available with various scents to choose from. 3. Regularly clean your car: Keeping your car clean and free from any lingering odors is essential. Vacuuming the interior, using fabric fresheners, and regularly washing the car's upholstery can help eliminate smells. 4. Avoid foods that cause strong odors: Being mindful of the foods you consume while in the car can help reduce the likelihood of strong odors. Opt for less pungent food options when traveling with passengers. Remember, good communication with your passengers is important. If someone is uncomfortable due to unpleasant smells, politely addressing the issue and taking their concerns into account can go a long way in making everyone's journey more enjoyable.

The disparity of the ridgevent and the whirlybird is very evident. The demo is not accurate.

[@Lomanco]

Exhaust products are part of a ventilation system. As long as the proper number of vents are used and the system is balanced, (50% exhaust and 50% intake), ridge vents, roof louvers, whirlybirds, power ventilators or gable vents will be equally effective. All of Lomanco's products are designed with the Lomanco Balance in mind- free movement of air and weather protection - and are equally effective. Often, the design of the home will determine what type of vent is used.

Could this product be clanged to generate electricity for high wind cold areas home with no attic?

[@Lomanco]

It is possible to retrofit turbine ventilators to generate electricity, but whether or not it's practical or cost-effective will depend on several factors. First, turbine ventilators are typically designed to ventilate hot air and moisture out of an attic space, so if you don't have an attic, you may not have the necessary airflow to generate significant amounts of electricity. Additionally, turbine ventilators are typically passive devices that rely on wind to spin the turbine and exhaust hot air. To generate electricity, you would need to install a generator or alternator to convert the rotational energy of the turbine into electrical energy. Assuming you have enough wind to spin the turbine and generate electricity, the amount of electricity you could generate would depend on the size and efficiency of the turbine and the generator or alternator. You would also need to consider the cost of the equipment and installation, as well as any regulatory or permitting requirements. In summary, while it is technically possible to retrofit turbine ventilators to generate electricity, it may not be practical or cost-effective in all cases. If you're interested in exploring this option further, you should consult with a professional contractor or engineer who has experience with renewable energy systems.

How much air speed until these thing start spinning? The thing is in some cases there are no air blowing makes the place very hot.

[@Lomanco]

Lomanco Whirlybird turbine vents, like the BIB-12, are designed to spin with very low wind speeds, typically as low as 5 mph. This low threshold allows them to begin venting even with minimal airflow. However, in cases where there is no wind, the turbine will not spin, which can reduce the venting efficiency. To address situations with little or no wind: 1. Ensure Proper Intake Ventilation: The effectiveness of turbine vents also depends on adequate intake vents (soffit or eave vents) to allow cooler air to flow into the attic. Without sufficient intake, even a spinning turbine won’t create optimal ventilation. 2. Utilize Passive Ventilation: Even without spinning, the vent can still provide passive ventilation through natural convection, where hot air rises and escapes through the vent. 3. Consider Another Lomanco Vent Product: In areas with consistently low wind or extreme heat, another Lomanco product, such as the Lo-OmniRoll Ridge Vent or Omni Ridge Vent, may better suit your needs. These vents work on the principle of passive ventilation and can provide effective airflow even in conditions where turbines may not spin consistently. Assessing your specific attic and roof design can help determine the best solution for your situation. Proper installation and balance between intake and exhaust vents are key to maximizing the performance of Lomanco turbine vents, even in less-than-ideal wind conditions.
