The chimney and hob are the only two appliances in a modular kitchen that are built into the design, which means getting them wrong is expensive to undo. The cabinet opening, the duct route, the gas point and the electrical point are all set during civil and carpentry work. Change your mind after installation and you are cutting into finished cabinetry.
Indian cooking is also unusually demanding on a chimney. Tempering mustard seeds, deep frying, roasting spices and searing meat all produce far more airborne oil than the Western cooking these appliances were designed around. A chimney that works beautifully in a European kitchen will grease up your ceiling within a year here.
This guide covers what actually matters when choosing a chimney and hob for a Bangalore home, and what you should expect to pay.
Chimney suction: the number that matters most
Suction power is measured in cubic metres per hour, and it is the single most important specification. It tells you how much air the chimney can move.
The rule of thumb is that your kitchen's air should be exchanged about ten to twelve times an hour. For a typical Bangalore kitchen of 80 to 120 square feet with a standard ceiling, that works out to a minimum of 1,200 cubic metres per hour.
Our practical recommendations:
- Small kitchen, light cooking, mostly two people: 1,000 to 1,200 m3/hr is adequate.
- Standard apartment kitchen, daily Indian cooking for a family: 1,200 to 1,500 m3/hr.
- Open kitchen connected to the living or dining area, or heavy frying and tempering: 1,500 to 1,800 m3/hr, without exception.
An open kitchen deserves special mention because it is now the default in new Bangalore apartments. When there is no wall between the hob and the sofa, every bit of oil vapour the chimney misses lands on your upholstery. Undersizing the chimney in an open kitchen is the most common and most regretted appliance decision we see.
Do not confuse suction with noise ratings or marketing terms like "filterless". Ask for the m3/hr figure.
Ducted or ductless
A ducted chimney pushes air out of the building through a pipe. A ductless or recirculating chimney passes air through a carbon filter and blows it back into the room.
Ducted is better, comprehensively. It removes heat, moisture, smell and oil from the kitchen entirely. Ductless only removes some of the odour and none of the heat, and the carbon filters need replacing every six to twelve months at a recurring cost.
Choose ductless only when the building genuinely does not permit an external duct outlet, which is rare in Bangalore apartments but does occur in some older buildings and in a few societies with facade restrictions.
If ducting, keep the duct run as short and straight as possible. Every bend costs you suction. A duct longer than about three metres or with more than two bends will underperform its rating noticeably. Use a rigid pipe rather than flexible aluminium where you can; flexible duct is convenient for the installer and costs you airflow.
Filter types
Baffle filters are the right answer for Indian kitchens. They use curved steel plates that force oil to condense and drip into an oil collector, and they keep working even when partially dirty. Clean them every three to four weeks in hot water and detergent.
Mesh filters clog quickly with Indian cooking and lose suction fast. Avoid them.
Filterless or auto-clean chimneys use centrifugal force to fling oil into a collection bowl, with no filter to clean. They are genuinely low-maintenance and are what we specify in most projects now. You empty the oil bowl every few weeks and run a heat auto-clean cycle monthly. The trade-off is a higher purchase price.
Chimney styles and sizes
Wall-mounted chimneys are the standard for a hob against a wall. Island chimneys hang from the ceiling over an island hob and cost significantly more, both for the unit and for running the duct through a false ceiling. Built-in chimneys hide inside an overhead cabinet, which looks clean but limits the size of the canopy and therefore the capture area.
Size the chimney to the hob, not to the cabinet. A 60 cm chimney suits a two- or three-burner hob; a 90 cm chimney suits a four-burner hob and is what most families should buy. The chimney should be at least as wide as the hob, and wider is better because vapour rises outward as it goes up.

Installation height
This is where most installations go wrong. The chimney should sit 65 to 75 cm above the hob surface for a wall-mounted unit.
Too high and it cannot capture the plume before it disperses. Too low and you will hit your head, and the flame can be disturbed. Installers frequently mount chimneys high to keep them clear of the user, which quietly destroys the appliance's effectiveness.
For an island chimney, 70 to 80 cm is the range, adjusted for the height of whoever cooks most.
Choosing a hob
The main decision is a built-in hob versus a freestanding gas stove. A built-in hob sits flush in the countertop, looks better, and is much easier to clean around because there is no gap between stove and counter. It costs more and requires a cutout in the countertop and a cabinet below sized to clear the gas connection.
Burner configuration for most Indian families: four burners, with at least one high-output burner of 3.5 kW or more for a kadai or a large pressure cooker, and one small simmer burner for milk and gravies. Three burners suffice for a couple; five burners are rarely used fully.
Brass burners last longer and distribute heat better than aluminium. Cast iron pan supports feel more stable and stay put; enamelled steel supports are lighter and tend to shift.
Auto ignition is standard now and worth having. Flame failure devices, which cut the gas if the flame goes out, are worth insisting on in a home with children or elderly members.
Toughened glass tops look excellent and wipe clean easily but can crack if something heavy is dropped. Stainless steel tops are effectively indestructible but show every fingerprint and water spot. Both are common; choose by how forgiving you need the surface to be.
Induction and electric hobs are gaining ground in Bangalore, particularly in homes with piped gas restrictions or a preference for electric. They are excellent for fast boiling and precise control, but a dosa tawa and a round-bottomed kadai do not work well on induction, so most families who go electric keep at least one gas burner. A mixed gas and induction hob is a sensible compromise.
What it costs in Bangalore
Treat these as planning ranges rather than quotes, as appliance prices move constantly.
Chimneys:
- Entry-level 60 cm, around 1,000 m3/hr, baffle filter: roughly Rs 9,000 to Rs 15,000
- Mid-range 90 cm, 1,200 to 1,500 m3/hr, auto-clean: roughly Rs 18,000 to Rs 32,000
- Premium 90 cm, 1,500 m3/hr plus, filterless with motion or touch controls: roughly Rs 35,000 to Rs 65,000
- Island chimney: roughly Rs 40,000 to Rs 1,00,000 plus
Hobs:
- Three-burner built-in hob: roughly Rs 10,000 to Rs 18,000
- Four-burner built-in hob, glass top, brass burners: roughly Rs 15,000 to Rs 35,000
- Premium four- or five-burner with cast iron supports and flame failure: roughly Rs 35,000 to Rs 70,000
Installation and ducting typically adds Rs 2,500 to Rs 8,000 depending on the duct run and whether core cutting through an external wall is required. Confirm whether your society permits core cutting and where the outlet may be placed before the appliance arrives.
What to decide before carpentry starts
Because these are built in, the following must be settled before the kitchen is fabricated: chimney width and mounting style, duct route and outlet position, hob size and cutout dimensions, gas point location, the electrical point for the chimney at the correct height behind the unit, and the cabinet depth below the hob to clear the gas hose and regulator.
Changing any of these afterwards means re-cutting the counter or rebuilding a cabinet.
Plan your kitchen appliances with us
The right chimney and hob depend on your layout, your ceiling height, your duct route and how your family actually cooks, not on which model is discounted this month. At YellowDot Design Studio we specify appliances as part of the kitchen design, so the cabinetry, gas point, electrical point and duct are all coordinated before anything is fabricated.
