If you are thinking of a wood stove, you should be thinking about the chimney after that. The best quality stove, furnaces, boilers, water heaters, and more can also perform well when they are connected to a chimney. They will work together as one system. The chimney will drive the system by exhausting flue gases from your stove and it simultaneously pulls fresh combustion air into your stove. The continuous air supply is important when it comes to maintaining a steady fire. That air supply depends on the chimney’s ability to exhaust any flue gases because they are produced by the stove combustion.

You can read on until the end if you want to know more before contacting chimney inspection if you think something is wrong.


The most basic in chimney design is based on the fact that hot air rises. The higher the temperature difference between exhaust fumes/gases in your chimney and the air outside, the gas rises at a faster pace. This is a natural movement of exhaust fumes that goes up the chimney draft. For it to have enough draft to maintain the right combustion, there is a particular volume of gases that should move through your chimney. This is known as the flow, and if the draft is stronger, the flow is greater.

Kind of Filter

There are three kinds of filters in any modern chimney – Cassette Filter, Baffle Filter, and Charcoal Filter. For an Indian kitchen, the Baffle Filter is the best because it removes oil and spice particles coming from the air and it keeps high suction power. A cassette filter has tiny holes in the aluminum mesh that will trap particles and it purifies the air. Charcoal filters have a layer that takes out odors and you can use it with Baffle and Cassette filters.


The right kitchen chimney should be the same size as the stove or larger, but it should never be smaller. A chimney with a size of 60 cm is better for a 2 to 4-burner stove, and 90 cm is great for a 3 to 5-burner stove. In case the chimney size is smaller compared to a stove/hob, some cooking fumes can escape the direct suction power and spreads in the kitchen.

Mounting Style

There are three mounting styles that you can choose from, which depend on your kitchen’s construction and available space. It should be built-in, an island, or wall-mounted. Based on the name, wall-mounted chimneys can be fitted on the wall and they are ideal for kitchens where there is a cooking stove against the wall. Your island chimney is great for modern homes where the cooking stove is in the middle of your kitchen. This is perfect for small kitchens, and a built-in chimney is compact and fixed, integrated into the kitchen woodwork so it will not take up additional space.

Suction Capacity

Kitchen hoods are available with suction capacities that are between 700 m3/hr to 1600 m3/hr. The rule is that more cooking requires higher suction capacity. In addition, since a lot of households have a family of four and can cook three meals daily, it consists of spicy, vegetarian, and non-vegetarian dishes. It is suggested that you invest in a chimney that has more than 1200 m3/hr suction power.


Make sure that you buy a chimney from a good brand that has free installation and quick after-sales service. Since they are doing a lot of heavy-duty work, chimneys need regular maintenance.
