Two hobs can carry the same burner count, the same glass finish and a similar price, and behave completely differently after three years of daily Indian cooking. The difference sits in components a showroom conversation rarely reaches, which is the metal in the burner, the geometry of the flame ports, the material of the pan support, and the way the unit is set for your gas supply. This guide works through those in the order that affects cooking quality and service life.
Start With the Burner, Because Everything Else Is Secondary
The burner is the engine. A hob with an excellent glass top and an average burner is an average hob.
Material
Full brass burners are the benchmark for Indian kitchens. Brass conducts heat well, resists corrosion from salt, steam and acidic spills, and holds its shape under years of high-flame cooking. Aluminium alloy burners cost less and warp over time, and a warped burner cap sits unevenly and throws an uneven flame that no cleaning will fix. The phrase to look for is full brass rather than brass-coated, because a coating is a finish while full brass is the component.
Port design
The small holes around the burner ring are flame ports, and their size, count and angle determine how evenly the flame spreads under a pan. Well-machined ports produce a continuous ring of short blue flames. Poorly finished ports produce gaps, long licking flames and hot spots that scorch one side of a dosa while the other stays pale.
Heat output
Burner power is quoted in kilowatts, and the useful figure is the spread across the hob rather than the single highest number. A practical Indian layout runs an auxiliary burner near one kilowatt for milk and slow simmering, two semi-rapid burners around one and three quarter kilowatts for everyday work, and a rapid or triple-ring burner above three kilowatts for a wide kadhai or a pressure cooker.
Triple-ring and wok burners
A triple-ring burner places three concentric flame rings under the pan so heat reaches the full base of a wide vessel instead of concentrating in a small circle at the centre. If you regularly cook in a large kadhai, this single feature changes the result more than any other upgrade on the hob. Models such as the ASF 94TM in the KAFF Ashford series are built around triple-flame burners for this reason.
Efficiency
A high-efficiency burner puts more of its flame into the pan and less of it up the sides, which shows up on the cylinder over a month. The visible sign is a compact flame that stays underneath the vessel instead of curling around it.
Match the Hob to Your Gas Supply
More new hobs disappoint their owners over this than over any specification on the box, and almost nobody raises it at the point of sale.
LPG from a cylinder and PNG piped into the home burn at different pressures and different calorific values. The burner jets, called nozzles or injectors, are drilled to different sizes for each. A hob set for LPG and run on PNG gives a small, weak flame. A hob set for PNG and run on LPG gives an oversized yellow flame that soots the underside of your vessels.
Most units ship configured for LPG because that remains the common connection across India. If your building has a piped gas line, tell the seller before delivery so the correct PNG jets are fitted and tested during installation. Changing jets later is a routine technician job, but discovering the mismatch on the first evening of cooking is avoidable.
Safety Features Worth Insisting On
Flame failure device
A flame failure device is a thermocouple sitting beside each burner. While a flame is burning, the thermocouple stays hot and holds a gas valve open. If the flame goes out because a pot boils over, a draught blows across the burner, or a knob is knocked, the thermocouple cools within seconds and the valve shuts the gas to that burner.
Look for the phrase full flame failure device, which means every burner is protected rather than only one or two. In a home with children or elderly family members, this is the feature to refuse to compromise on.
Ignition
Auto electric ignition lights the burner from the knob itself. On most built-in hobs it draws from a small mains connection, which is why a hob needs a power point nearby even though it cooks on gas. Manual ignition avoids that entirely, and some buyers still prefer it for the simplicity.
Sealed burner base
A well-sealed burner base stops boil-over liquid from running into the body of the hob, where it corrodes components and is impossible to clean.
The Cooking Surface
Toughened glass
The current standard is 8 mm black toughened glass, which resists scratching, tolerates the weight of a full pressure cooker and wipes clean in seconds. Thickness matters because it governs both impact resistance and how the panel copes with thermal stress. A thinner panel is more likely to crack when a hot vessel meets a cold surface. Finishes range from high-gloss black to frosted and matt, and a frosted or matt panel hides fingerprints and water marks better than gloss does.
Stainless steel
A steel top absorbs knocks that would chip glass and is the more forgiving surface in a heavy-use or commercial-style kitchen. It shows fingerprints and water spots and needs wiping to stay bright. Brushed stainless finishes, as used in the Robusta series, sit between the two on appearance.
Edge treatment
On a built-in hob, look at how the panel meets the counter. A slim, flat edge sits closer to flush and leaves less of a lip for oil to collect against, and it is easier to seal cleanly.
Pan Supports and Knobs
These two components are handled more than any other part of the hob and are where cost-cutting shows fastest.
Heavy cast iron pan supports hold a full pressure cooker or a wide kadhai steady, absorb heat without distorting, and stay put when you stir hard. Enamelled cast iron adds a coating that resists staining. Thin pressed-steel supports flex under weight, rattle, and discolour within a year.
Look also at how the supports are arranged. Continuous supports spanning the full hob let you slide a heavy vessel from one burner to another without lifting it, which matters when the vessel is full.
Knobs should be metal rather than plastic, should have a positive click at the ignition position, and should give fine control between the low and high ends of the range. A knob with a narrow usable band between a roaring flame and a flame that dies is the sign of a poorly calibrated gas valve. A ridged or contoured knob turns cleanly with oily hands, which is the condition it will be used in most evenings.
Size, Burner Count and the Counter Cut-out
Burner count follows how many pans you run at once on your busiest day, plus one for headroom. Widths on built-in hobs run from compact 30 cm units through the common 60 cm size, into 75 cm and 78 cm for wider burner spacing, and out to 90 cm and 100 cm for large kitchens and five-burner layouts.
Physical fit is settled by the cut-out dimension rather than by the overall width. The cut-out is the rectangular opening the fabricator makes in your stone, and it always comes in smaller than the outer panel, which is what lets the panel rest on the surrounding surface. Take these three steps before ordering:
-
Read the cut-out dimensions from the specific model’s product page or manual rather than assuming a standard size.
-
Measure the counter depth as well as the width, and confirm there is enough stone left in front of and behind the opening for structural strength.
-
Check the cabinet below for clearance, especially where a drawer or a built-in oven sits underneath, since the hob body and its gas connection need depth.
An oversized cut-out cannot be corrected. A slightly undersized one can be widened. When in doubt, have the fabricator cut small and open it out to fit.
Planning the Hob With the Chimney and the Oven
A hob is one element of a cooking zone, and the other two should be decided at the same time.
Settle the chimney width in the same conversation as the hob width, since the hood is sized from the cooking surface beneath it. Mounting height then follows the specification for that particular hood, and that figure is worth checking against your wall cabinet layout before the cabinets are made, because a hood forced higher or lower than its design height will underperform whatever the rating says.
If a built-in oven is part of the plan now or even later, leave the cabinet below the hob free and run a power point into it during the electrical work. Retrofitting that socket afterwards means opening finished carpentry for a job that costs almost nothing while the wiring is still exposed.
Judging Build Quality in a Showroom
Five checks take two minutes between them.
-
Lift a pan support. It should feel heavy and drop back into its locating points without sliding around.
-
Turn every knob through its full range. The movement should be smooth and consistent from one knob to the next.
-
Lift a burner cap and look at the flame ports. They should be cleanly machined and identical around the ring.
-
Look at the underside of the panel edge for finish quality, since a rough edge is a fair indicator of the rest of the build.
-
Ask whether the burners are full brass and whether the flame failure device covers every burner.
Installation and After-Sales
A built-in hob is fitted once and lives with the counter, so the quality of the fitting matters as much as the quality of the appliance. An authorised technician sizes the cut-out against the specification, seals the perimeter against seepage, connects the gas line and the ignition supply, confirms the jets suit your gas type, and tests every burner before leaving.
Before buying, check there is an authorised technician within reach and that the series is still supported with spares. Warranty cover is defined model by model and part by part, so take it from the product page itself.
Before the Technician Leaves
The half hour after installation is the only easy window to catch a problem, because every correction gets harder once the sealant has cured and the kitchen is back in daily use.
Light each burner in turn. A compact blue flame sitting steady on the port ring is what a correctly set hob looks like, and yellow tips or a flame lifting away from the ports means something needs adjusting.
Take each burner down to its lowest setting and leave it there for a full minute, because a flame that dies at minimum is a valve or jet problem rather than a quirk to work around. Stand a filled vessel on the largest burner and confirm the support carries it without rocking. Then test the flame failure device on one burner and time how long the gas takes to cut.
Raise anything that fails before the technician packs up. A correction made on installation day is part of the fitting. The same correction a month later is a service call you have to book and wait for.
KAFF builds built-in hobs across several series in two to five burners and widths from 30 cm to 100 cm. Filtering by burner count and width first, then working through the details above, gets you to the right model faster than starting from the finish.
Frequently Asked Questions
Q. Which hob is good for Indian cooking?
A. For Indian cooking, a hob with heavy brass burners is the best choice because it provides the high heat needed for heavy frying, boiling, and making rotis. You should also look for a hob with strong, cast-iron pan supports so that heavy kadhais and pressure cookers stay fully stable while cooking.
Q. How do I know what size hob to buy?
A. To choose the right size, measure the available space on your kitchen counter and check the width of your kitchen chimney. Your hob should ideally be the same width as your chimney or slightly smaller. A 60 cm hob is great for 3 burners, while a 75 cm to 90 cm hob is best if you need 4 or 5 burners.
Q. What is flame failure device in hob
A. A Flame Failure Device (FFD) is a very important safety feature in modern hobs. If the burner flame accidentally goes out due to heavy wind or milk boiling over, the FFD automatically stops the gas supply immediately. This prevents dangerous gas leaks and keeps your kitchen safe.
Q. What is the standard size for a hob?
A. The most common and standard size for a kitchen hob in India is 60 cm (about 24 inches) in width. This size easily fits 3 to 4 burners and matches standard 60 cm chimneys perfectly. For bigger kitchens with more cooking needs, 75 cm and 90 cm are also very standard sizes.
