Range hood, ventilated or not ventilated?

Range hood, ventilated or not ventilated?

Q: I am rebuilding the kitchen. My contractor friend told me that all new houses have fume hoods. Should I replace the recirculating range hood with a ventilated one?

A: It depends. If you have a gas stove or oven, installing a vented range hood should be a priority. When in use, the gas range includes discharged water vapor and various gases, such as carbon monoxide. You don't want to stay in the kitchen to mold or make you feel uncomfortable.

If you have an electric stove, a vented range hood is a great investment, but the decision to install it should be based on your cooking habits and your budget. If most of your food is cooked on a stove, and you often feel that you need to open a window to remove residual fragrance or vapor accumulation, then a ventilated stove cover will be a good investment to take these things away from your home. I am very grateful to my ventilated range hood, which can remove steam in hot summer and cooking disasters, such as baked biscuits or sweet potato pies overflowing from the oven.

Whether you own a gas cooker or an electric cooker, evaluate your current range hood by answering the following questions:

1. Does the range hood exhaust outward? The range hood is ventilated through the roof or external wall. Look for the exhaust cover that passes through the metal pipe above the cabinet or the exterior wall behind the range hood. When the fan is running, you should feel the air blowing out from the exhaust cover on the roof or wall.

2. Can the range hood absorb enough air? When the fan is turned on, an 8 x 11 piece of paper or a piece of paper from a Carolina country magazine should be easily held on the fan filter by air suction. If the fan does not suck enough air, this problem can be solved by repairing the fan or improving the piping system.

3. Can the existing range hood be ventilated? Almost all residential range hoods can be installed for recirculation or ventilation. Please refer to the installation instructions, or with the fan turned off, remove the filter and look for the "off" point. These are rectangular or circular panels that can be removed to install pipes above or behind the hood.

If you want to ventilate the existing recirculation range hood, the recirculation exhaust position needs to be closed. The position is usually at the forehead height. It needs to be delivered to the outside through newly installed vents, rather than blowing air from the forehead.

If you are purchasing a new ventilated range hood, please select a fan with a rated pulling force of at least 120 cubic feet per minute (CFM) and a maximum of 600 CFM. Excessive ventilation of residential range hoods can lead to problems, such as the air return of gas fireplace. Get product recommendations from friends and pay attention to customer comments. Microwave ovens can also be used as ventilators!

Follow manufacturer's instructions on installation, height and maintenance of range hood. The pipes of the range hood shall be made of metal plates and shall be as short and straight as possible. Length and turn will limit the range hood's ability to fully absorb air. Pipe joints need to be properly sealed and ventilation caps need to be easily opened. Exhaust should not be transported to attics or crawl spaces.

In any kitchen renovation project, improving the range hood is a good consideration!
