Gas, Induction or Electric, Honestly Compared

Read the wall behind an old range before you choose a new one

If there is a range in the kitchen now, pull it out before you decide anything. Lift the front a little and walk it forward on a towel. If it is gas, go gently — the connector behind it is short — and if you smell gas, stop and call a gas fitter. How that kitchen has cooked is written on the cabinets beside the range, the wall behind it and the ceiling above, and a tear-out crew reads it in a minute.

1. The cabinets beside and above the range. Run a fingertip down the side of the wall cabinet nearest the range. In a kitchen that has cooked on gas for years under a weak hood, it is tacky and amber, and a paper towel comes away brown. The film is cooking grease, and every fuel makes it; a gas flame adds heat and water vapour that carry it further and bake it on harder. What it tells youHow much of what came off the pans the hood failed to catch. The fuel added to it; the hood decided it.
2. The grout behind the back burners. Over an old gas range the grout behind the back burners is often a shade or two darker than at the ends of the counter, rising in a rough fan. Behind a glass top it is usually fainter, because no flame is pushing hot, wet air up the wall — though frying spatter marks grout over any fuel. What it tells youSpatter and moisture land on the first cool surface behind the pans. Whatever you choose, plan a backsplash there that wipes clean.
3. The ceiling. Look straight up. A faint grey bloom on the ceiling, sometimes a ring round a pot light, is common over a gas range that ran for years under a recirculating hood or one rarely switched on. Paint over it without degreasing and priming and it tends to come back. What it tells youWhat rose off the cooktop and was never taken out of the house. On gas that includes the burners’ own exhaust — the reason gas needs a duct more than the others do.
4. The top. Gas: grates with the enamel chipped off their feet and one burner lighting with a gap in its flame. Radiant glass: a haze of grey scratches round the big front element, and a brown ring no scraper has shifted. Induction: often a top that still looks nearly new, with one long scratch where a cast-iron pan was dragged. What it tells youGlass wears where pots are dragged. Radiant glass also bakes spills on, because the glass is the hot part; induction’s is only warmed by the pan.
5. The wall behind. The one that matters most. A gas range leaves a shut-off valve on a short pipe from the wall or floor, a flexible connector, and an ordinary 120 V outlet for the igniters and controls. An electric or induction range leaves a big heavy-duty receptacle — or, behind a cooktop or wall oven, a cable into a metal junction box — fed from a double breaker in the panel, much bigger than the ones for the lights. What it tells youWhat the house can feed today without anybody opening a wall. That is always the easiest fuel to keep.
6. The hood. Pull out the metal filter and look up with a flashlight. A duct running up into the cabinet or wall means it vents outside. A charcoal filter and slots in the front mean it has been blowing everything back into the room. Plenty of old hoods were meant to be ducted and never were. What it tells youWhether this kitchen has ever really been ventilated. A new gas range under the same hood will write the same story on the new cabinets.

Now notice what you did not find. Nothing about the cabinets themselves was different. The opening was 30″ in the gas kitchen and 30″ in the electric one, and the cabinets either side were the same, because all three fuels come as a standard 30″ range that drops into the same gap. The fuel is decided by the wall behind the range and the hood above it; the cabinets only need the right opening, the right clearances and, for a cooktop, the right cutout.

What they search at midnight “gas vs induction range” — the answer starts behind the range, not on top of it.

Gas — and why the biggest burner matters least

Here is what the brochure leaves out. A gas flame does not just heat the pan; it wraps up round the sides of it, into the handle, the grate and the kitchen air. Lovely under a wok, wasteful under a small saucepan, and in August you feel it on your face.

“Gas” is also not one product. Four things separate a good one from a shiny one:

• The low end, not the high end. The showroom talks about the biggest burner. What you feel every day is whether the smallest one, turned right down, holds a pot of rice or a cream sauce without scorching it or going out. Look for a dedicated simmer burner, or one with a small inner ring
• Sealed or open burners. Nearly every home range has sealed burners on a pressed top, so a boil-over stays where you can wipe it. Some pro-style ranges use open burners over a spill tray; nobody likes cleaning them
• The grates. Continuous cast-iron grates let you slide a heavy pot between burners. They are heavy, and the enamel chips at the feet over the years. Check that each section fits in your sink
• The gas it is set up for. Ranges arrive set for natural gas. On propane, common at cottages, a gas technician converts it with the maker’s kit before it is lit

None of that is a reason to avoid gas. It is a reason to buy the hood and duct as part of the range, and to have a carbon monoxide alarm in the house.

Induction — and why “induction” is not one thing

People talk about induction as if it were one appliance. It is a family, and six things hide inside the word:

• Full power or plug-in. A built-in cooktop or full-size range runs on its own 240 V circuit, like an electric range. A plug-in hob of one or two zones runs from an ordinary 120 V outlet at a fraction of the power — fine for trying induction or an extra burner, not a replacement for a cooktop. A few full-size plug-in ranges are sold for homes without the heavy circuit; they are a niche, so read what they give up
• Zone size against pan size. The pan has to cover enough of the coil to be detected. A small saucepan on a big zone may not register; a wide pan on a small zone heats a disc in the middle. Hold your own pans against the circles
• Bridge and flex zones. A bridge joins two zones into one for a griddle; a flex zone finds the pan wherever you put it. Useful if you cook that way, decoration if you do not
• Power sharing. Zones usually share power in pairs, and the whole top has a ceiling. Boost one and its partner may quietly drop. Ask which zones share
• The hum. Some pans hum or buzz at high settings, especially multi-layer pans or bridged zones, and a cooling fan runs during and after cooking. Most people stop hearing it within a week; a few never do
• The magnet test. If a fridge magnet grips the bottom firmly, the pan works. Cast iron, enamelled steel and most stainless pass; plain aluminium, copper, glass and many ceramic pans fail unless a steel plate is bonded underneath. A round wok becomes a flat-bottomed one

And one more thing the word hides: the glass still scratches. It does not bake spills on, but a dragged cast-iron pan leaves a line, and a grain of salt under a pan acts like sandpaper. Lift, do not slide; the care page has the rest.

Radiant electric — the smooth-top everyone has cooked on

Turn a radiant zone down and the pot keeps boiling for a while. Cooks who grew up on radiant move the pot off the zone instead, and switch off a minute early. It is a habit, not a flaw — but it makes radiant the least precise of the three.

Look for multi-ring elements, a bridge for a griddle, and a hot-surface light for every zone, because the top stays dangerous after it looks off. Baked-on spills are the daily weakness, and makers warn that sugar left to cool on hot glass can pit it, so it is scraped off promptly with a cooktop razor.

Coil elements — open spirals in drip bowls — are the oldest and least expensive electric top: slow, fiddly to clean, close to indestructible, and each element unplugs for replacement. They use the same 240 V supply, so a coil range swaps for a smooth-top or induction in the same opening.

Where the heat goes, and how each one wears

The three tops make heat in three different places, and nearly everything else follows from that.

So, without anyone’s laboratory numbers: induction puts most of its heat into the pan; gas heats the room as well; radiant sits between and keeps heating the glass after you finish. How they age follows the same lines.

The first week. On gas you discover the simmer burner is the one that matters. On induction the boost setting boils a pot over before you are back from the fridge, and one pan hums. On radiant you learn to lift the pot rather than turn it down.

The first month. The gas grates need their first soak, and the habit of switching the hood on has either formed or not. Induction glass shows faint rings that a cream cleaner lifts. Radiant glass gets its first browned ring from a pasta boil-over.

A year in. Gas: a burner lights with a gap where food got into the ports, and the nearest cabinet feels tacky if the hood is weak. Induction: fine scratches round the busiest zone, visible in low light. Radiant: a grey haze round the big element, and a ring that no longer comes off.

Ten years on. On gas the burners are usually fine; igniters that will not stop clicking are the common repair. On induction the parts that wear are electronic — the control board and the fan. On radiant an element can burn out and is replaced on its own. On both glass tops, a cracked glass from a dropped pot is the big repair.

And under a hand: gas grates stay hot long after the flame is off; a radiant top is too hot to touch across the whole circle for minutes; an induction top is warm only where the pan sat.

Freestanding, slide-in, or a cooktop and a wall oven

Fuel is one question. The shape of the appliance is another, and it cuts straight across the first: all three fuels come in each of these. For the cabinets and the counter, the format matters more than the fuel.

• Freestanding range. Finished sides, usually a back guard with the controls, and it slots into the 30″ gap. The counter stops at each side, leaving a crumb gap. The least expensive format, the easiest to swap, and the only one that can stand at the end of a run
• Slide-in range. No back guard, controls at the front, and a top that overlaps the countertop edges either side, so there is no crumb gap and the backsplash runs behind it. The sides are usually unfinished, and the counter is cut to suit the exact model. A front-control freestanding range splits the difference
• Cooktop and wall oven. The cooktop drops into a counter cutout over a 30″ or 36″ base; the oven goes into a tall cabinet where nobody has to bend. Two appliances means two connections, and whether one circuit can feed both is the electrician’s call. It costs a tall cabinet’s worth of wall, and it is the usual route for an island cooktop
• Dual fuel. A gas top over an electric oven. It needs both a gas valve and a 240 V circuit behind it

Then there is size. A 36″ or 48″ pro-style range is a different kitchen: a wider opening, a bigger hood, more air to move on gas, and sometimes more clearance to the cabinets beside it. Decide that before the cabinets are ordered. Cooktops in islands have their own page.

What switching fuel really costs — in work, not money

What they search at midnight “switching from gas to induction” — the range is the easy part; the circuit is the job.

Switching fuel is not an appliance decision; it is a small renovation with a trade at each end.

From gas to induction or radiant electric. An electrician runs a new 240 V circuit: a heavy cable, a double breaker, and a receptacle or junction box. Whether the panel has room, and whether the house’s service can carry one more large load, is a calculation the electrician makes on site. Sometimes it is a simple addition; sometimes it means a new panel, occasionally a larger service. Get that answer before you buy the range. On the gas side, a licensed gas fitter caps the line and removes the old connector; if the furnace still runs on gas, the meter stays.

From electric to gas. A gas fitter runs a line from the nearest supply, usually up through the floor, with a shut-off valve where it can be reached, and the range needs an ordinary 120 V outlet too. With no gas service at all, the job starts with the utility. The hood comes with it: if there is no realistic path for a duct outside, that is a strong argument for staying electric.

In a condo. Many suites have no gas, and new circuits or ducts through an outside wall go through the building first. What a condo will let you do usually settles the fuel before you reach a showroom.

The cheapest moment for any of it is when the walls are open, before the cabinets — the argument of the renovation order page. If they are open anyway, ask both trades what it would take to rough in the other option too.

What the fuel changes in the cabinets and the counter

For the cabinets, the fuel changes less than people fear. The appliances chapter has every range number; here is how they fall by fuel.

• The opening. Any standard range drops into a 30″ gap. Leave it a true 30″, because ranges are built a whisker under
• A slide-in and the counter. The top overlaps the countertop, so the counter is cut to that exact model. With quartz, the fabricator templates after the range is chosen
• A cooktop’s cutout. Always smaller than the cooktop, and taken from the model’s sheet. A fabricator rounds its inside corners, keeps seams out of it, and leaves enough stone in front and behind. Flush-mounted cooktops need a routed ledge — decide before templating
• What goes underneath. Gas has a burner box and connection hanging down, electric a junction box, induction its body and its need for air. Most rule out a full drawer stack; the usual answer is a false front over a shallow drawer, or an oven the maker approves
• The hood height. From the cooking surface to the bottom of the hood: 24–30″ above gas, 20–24″ above electric or induction. A plain cabinet needs 30″, or 24″ with its underside properly protected. Switch fuel and the cabinet above the hood can move too
• Heat beside the range. During a self-clean cycle the cabinets either side get very warm. Thermofoil doors and end panels — a vinyl skin over MDF — can bubble or peel from it, which is why heat shields exist. Some ranges list side clearances; the sheet says

One counter habit belongs here. Quartz is bound with resin, so a pan straight off a burner or out of the oven goes on a trivet, not on the stone. Quartz and granite are compared on their own page.

Five things the fuel does not decide

A lot of the heat in this argument comes from blaming the fuel for things it has nothing to do with.

1. The size of the opening. All three come as a standard 30″ range between the same cabinets.
2. How well the oven bakes. That is the oven. Gas ranges usually have gas ovens, dual-fuel ranges electric ones, induction and radiant ranges ordinary electric ovens. Judge the oven on its own.
3. Whether you need a hood. All three do. Grease, steam and smoke come off the food; gas adds its own exhaust on top.
4. How the kitchen looks. That is the format, the hood and the backsplash. Two slide-ins of different fuels look more alike than a slide-in and a freestanding range of the same fuel.
5. Which counter you can have. Quartz, granite and porcelain all take any of them. What matters is the cutout, the trivet and how each surface handles heat.

And one piece of language to watch for: “professional” or “pro-style”. It describes a look — heavy knobs, stainless, chunky grates. On gas it may also mean high-output or open burners that need a bigger hood and more clearance. Ask what, exactly, is professional about it.

How to shop for a range when nothing on the floor is plugged in

Most showroom ranges are not connected, so you cannot taste the difference. Bring things instead: a fridge magnet and your two most-used pans for the induction zones, and photos of the wall behind your range and the breaker labels. Lift a grate. Then ask the questions that tell you more than the badge:

• Can I have the installation sheet for this exact model number? — not the series; the page with the cutout, the clearances and the service zone
• Where on the wall must the valve or receptacle be? — so the range sits flat against the wall
• What circuit does it need, and does it come with a power cord? — for your electrician
• Which zones share power, and what is the smallest pan each will detect? — for induction
• What is the lowest setting on the smallest burner? — for gas
• What can go in the cabinet underneath? — for a cooktop
• What clearance does it need at the sides and above? — to cabinets and to the hood
• Can it be converted to propane, and who supplies the kit? — if you run on propane

What we would do, kitchen by kitchen

General rules are easy. Here is how the choice actually falls for the kitchens people really have.

A family house you plan to stay in. Induction, if the panel can carry it: fast, cooler, wipe-clean, and a zone stops heating when the pan comes off, which matters with small children about. If gas is already there and the wok comes out most nights, gas — under a ducted hood you will actually switch on. Decide before the cabinets are ordered.

A condo. Induction, or radiant on a budget. Most suites have no gas, and where there is gas a duct outside is often impossible, leaving gas under a recirculating hood — the combination this page warns about.

A basement suite. A freestanding radiant smooth-top. Least expensive, any flat pan works so a tenant’s cookware is never the problem, and the circuit takes induction later.

A cottage. On propane already, a gas range converted by a gas technician keeps cooking when a storm takes the power — on many models the top burners can be lit by hand. All-electric, radiant or coil is simple and forgiving; induction means a second set of pans.

A rental you own, or a house you are fixing to sell. Keep whatever the wall already feeds and spend on the format: a slide-in or front-control range with the backsplash behind it looks planned. Buyers judge the look and the hood, not the fuel.

A small kitchen. Induction: no flame near a tea towel, a room that stays cool, and cool glass that reads as a little more counter. If the wall is short, 24″ ranges exist; the small-kitchen guide shows where one goes in a galley.

Someone who cooks hard every day. A round wok and high heat: gas, under the best ducted hood the wall allows. Precise everyday cooking — sauces, searing, pasta for six: induction does it faster, with a flat-bottomed wok. Either way, plan the opening and hood first.

• No gas in the building, or no way to duct a hood outside. Induction, or radiant on a budget.
• A round wok, charring, cooking by the flame. Gas, under a hood ducted outside.
• Small children, or the cooktop doubles as counter. Induction.
• A tight budget and ordinary cooking. Radiant smooth-top, wired so induction can follow.
• A propane cottage where the power goes out. Gas, converted to propane.
• Switching from gas. Induction, after an electrician has looked at the panel.

If you are keeping the range you have

Most people reading this are not buying a range this month. An hour on a Saturday makes the one you have safer and easier on the cabinets — and answers most questions about the next one.

1. Check the anti-tip bracket. Pull the storage drawer and look at the back feet with a flashlight. A back foot should sit under a bracket. If there is none, the maker sells one; it is a four-minute job.
2. Clean the burners and look at the flame. On gas, lift the caps, clear blocked ports with a pin, and dry everything. A healthy flame is blue and even all the way round; if it stays yellow or lifts after cleaning, call a gas technician. If you smell gas, leave and call from outside.
3. Test the hood. On high, it should pull a square of paper towel up and hold it. Then find the flap outside. No flap anywhere means it recirculates, and its charcoal filter is probably overdue.
4. Find the shut-offs and the alarm. Find the gas valve or the range breaker, and label it. If anything in the house burns gas, test the carbon monoxide alarm.
5. Do the magnet test. Even if induction is years away, magnet every pan you own. It turns a vague future cost into a short list.
6. Look at the cabinet beside the range. Wipe the nearest cabinets with warm soapy water and dry them. Check thermofoil doors near the oven for bubbles or lifting edges; a heat shield stops it getting worse.

The neighbouring choices are waiting too: which hood goes above it, which stone goes around it, which doors go beside it, and every range and hood number in the appliances chapter.
