Range hood how much cfm

The more heat your range produces, the more CFM you need for your kitchen range hood. Keep in mind that other factors like length of ductwork, number of elbows, and the size of your kitchen may impact the CFM.

You can purchase range hoods CFM and under at several big box stores, but they will not match the quality of range hoods with a higher CFM rating. We recommend high-CFM hoods to our customers because they can always use them on lower speeds. A higher CFM is ideal because it allows you to cook a wider variety of foods compared to weaker hoods, while keeping your kitchen air clean and fresh.

But it is not always your best option if you:. This means you will be removing more air from your kitchen than is necessary, potentially causing you to lose the heat you want in your home. As mentioned above, your ductwork impacts the capacity of a high power blower to remove air. Your hood will not be able to do its job if your ductwork is too small, too long, or has too many bends. We get calls every week from people that regret not getting enough before so they are looking for a new hood now.

Range hoods need to have the proper amount of overhang and depth for them to work effectively. The further your hood extends past the edges of your cooktop, the better — particularly if you have an island range.

Be sure your hood is at least a size or two up from your stove or has three to six inches overhang. If you have an outdoor kitchen, aim for your hood to extend six to 12 inches past the cooktop. On the other hand, if the range hood is positioned too close to the cooking surface, it will not be able to effectively capture the cooking air either. It can also heat up too much as you are cooking and the life of your hood can be greatly reduced.

If you scale up the size of the hood it will make less sound. With a larger capacity, you will be able to run your hood at lower and quieter speeds as well.

Also, you can opt for an inline or remote blower instead of an internal one. This means the noisy part, the blower, of the range hood will be further away from you and it will be much quieter. More on the different types of blowers here. Most CFM hoods are manufactured cheaply at big box stores, so they are not very durable. In general, the quality of your hood will increase as CFM increases since higher-CFM hoods need to be built to withstand heavy smoke and grease.

When determining the CFM you need for your range hood, one of the most important things to consider is the British thermal unit BTU output of your cooktop. Then divide by to get CFM. The average stove top burner produces about 7, BTUs.

Lower-heat burners to cook soup or sauces range between and BTUs, while some higher-heat burners reach up to 12, BTUs. Most ranges have between 4 to 6 burners.

Assuming you have six high-heat burners, your range will produce 72, BTUs. Think of it more as a minimum. But regardless, we know that your range, using the example above, mandates a CFM range hood.

The most powerful residential range hoods are about CFM, while commercial ranges require up to two to three times that amount. The roof or wall vent cap will also have an affect on the range hood CFM. If the vent cap has small holed cover, or if it abruptly stops air flow, it will reduce the range hood CFM. The longer it takes for the vented air to get to the outside, the more performance degradation the range hood will experience.

The best vent runs are very short such as less than a few feet. Of course, many times it isn't feasible to have a short vent run such as if you have to go through an attic.

If you have the choice, choose the shortest route possible to the outside with the fewest number of turns. When choosing the right CFM for your range hood, it general, you want to follow the recommendations of the Home Ventilating Institute.

You also want to take into account the quality of your duct, the number of turns, and other factors. You may also want to look at the total BTU output of your range burners. Looking to learn more about home maintenance? Check out our other informative home product reviews and guides!
