When you install a range hood, you must determine the correct mounting height for the range hoods. Range hoods that is mounted too low will obstruct your view of the cookware that you are cooking with. Range hoods that are mounted too high will fail to capture the steam and grease that emerges from the cooktop while cooking.
If you mount the range hood too high, the steam from the cooking process will bypass the filters of the range hood. Thus, you must balance the height of the range hood with the heat that are produced by the cooktop upon which you will cook. The type of cooktop that you use will play a major role in the mounting of your range hood.
How high and wide to install a range hood
If you use a gas cooktop, it will produce an open flame. Furthermore, the flame will produce a plume of hot air that will rise from the cooktop. Because the gas cooktop will produce this type of heat, the range hood must be mounted higher to ensure that the heat does not damage the cooktop finish.
Additionally, mounting the range hood too low over the gas cooktop can lead to a fire hazard. Conversely, if you use an electric or induction cooktop, there will be no open flame. As a result, the range hood will produce more localized heat from the cooktop.
Consequently, the range hood can be mounted lower than the height required for the gas cooktops. However, if you are cooking with high heat, such as when searing meat, the range hood must be mounted higher so that the smoke will have a chance to spread out before the range hood captures it. Beyond the cooktop, the style of your range hood will also play a role in how high you mount it.
For example, if you mount the range hood on a wall, it is mounted higher than range hoods that will sit on an island in the kitchen. Furthermore, if the range hood is an under-cabinet insert, you must ensure that it fit in the vertical gap in the cabinet. Additionally, you must also consider the chimney cover of the range hood, especially if its a professional-grade range hood.
The chimney cover may extend to the ceiling if someone mounts the range hood incorrectly. Beyond the height of the range hood, the width of the range hood is also important. Even though it may be tempting to make the range hood the same width as the cooktop, this will not allow the range hood to properly capture all of the steam that emerges from the cooking process.
Smoke and steam dont travel in straight lines. Thus, the width of the range hood must be wider than the width of the cooktop. A range hood with a wider width will have a wider capture area for the steam and smoke, preventing it from escaping into the remainder of the house.
When measuring your range hood, you must take note of where you measure. Many individual will take the measurement from the edge of the countertop. However, you must measure from the cooktop to ensure accuracy in the installation of the range hood.
If you dont use accurate measurements, you run the risk of installing the range hood too low. A range hood that is too low to the cooktop may be damaged by the heat that are produced by the professional range. Furthermore, you can also use your own height as a consideration in the mounting of the range hood.
If you are a tall individual, you may want the range hood mounted higher for more head room. However, if you mount the range hood too high, it will lose it’s suction power. A range hood with less suction power is less efficient.
Thus, a less efficient range hood will require you to turn its fan to a higher setting then a lower priced range hood to achieve the same level of air quality. Finally, to ensure that the range hood that you install into your kitchen is functional and effective at performing its tasks, you must ensure that it is high enough to allow for head room and low enough to provide ventilation for the kitchen. You must also ensure that the range hood is wide enough to capture the smoke and the grease that is created while cooking.
By following these guidelines and measurements, you will find that the installation of the range hood will be a matter of math rather than guessing.
