# The Electric Induction Stove Mistakes Worth Avoiding Before You Buy **By Joy David** ยท 2026-06-22 Most induction stove regrets are not about the technology. The heat is fast, the surface stays cool around the zone, and the energy use is genuinely lower than gas. The regrets come from four or five things a buyer did not check before the countertop was cut or the old hob was thrown out. Get those checks done first, and the purchase is almost always a good one. ![Woman using a built-in induction hob in a bright condo kitchen with city views](https://cdn.shopify.com/s/files/1/1805/8667/files/woman-using-built-in-induction-hob.jpg?v=1782095310) **Quick answer:** Before buying an electric induction stove, confirm your cookware is ferrous (magnet-sticks test), verify the circuit your kitchen supplies, match the wattage to your household's actual cooking needs, and measure the cutout width for built-in models. These four steps prevent the most common post-purchase regrets. ## Mistake 1: Assuming Your Existing Cookware Will Work This is the most common and most expensive oversight. Induction cooking works by inducing a magnetic field in the pan itself, which means the pan has to be made of a ferrous (iron-containing) material. Stainless steel marked "induction-ready," cast iron, and carbon steel all work. Pure aluminium, copper, and most older non-stick pans do not. The test takes five seconds. Hold a fridge magnet to the base of the pan. If it sticks firmly, the pan will work. If it slides off or barely grips, it will not heat up at all on an induction zone. Buyers who skip this check arrive home to find that their full set of premium pots is now decorative. If you are replacing most of your cookware anyway, plan the budget before you finalise the hob choice, not after. **[Induction-compatible cookware](https://megafurniture.sg/collections/induction-cookware)** varies considerably in quality and thickness, and a thin stamped base will heat unevenly regardless of how good the hob is. Cast iron and heavier tri-ply pans are worth the step up if you cook daily. ## Mistake 2: Not Checking the Kitchen Circuit Before the Countertop Is Cut Singapore mains run at 230V, 50Hz. A standard 13A wall socket can supply roughly up to 3,000W before tripping. A portable single-zone induction cooker typically draws around 2,000W, which sits within that, so plugging it into a standard socket works. The problem arrives with built-in hobs. A built-in two-zone induction hob typically runs at 3,000-3,500W total. A 60 cm four-zone model often draws 7,000W or more. Those units need a dedicated higher-rated circuit, wired by a licensed electrician, before installation. If your kitchen was last renovated in the 1990s or earlier, the wiring may not support it, and finding that out after the countertop has been cut is a painful and expensive lesson. The fix is straightforward: ask your electrician to check load capacity before you confirm the hob model. If a dedicated circuit is needed, factor in the electrical works cost when you compare prices between models. Many renovation contractors overlook this as a separate line item and buyers are surprised when it appears on the final bill. ## Mistake 3: Buying More (or Less) Power Than You Actually Need Wattage is where spec-aware buyers can over-optimise. A four-zone 7,000W hob is impressive on paper, but if you live alone or cook for two people on two zones most evenings, you are paying for capacity you will rarely use, and you have committed a dedicated circuit for it. Conversely, a portable 2,000W single-zone induction cooker is a reasonable stepping stone but is genuinely limiting if you want to stir-fry and boil soup simultaneously. A useful way to calibrate: count the number of burners you actually use at the same time during your heaviest cooking session in a week. For most Singaporean households cooking Chinese-style, that is two to three zones. A 60 cm two-zone or three-zone built-in hob covers this without requiring a circuit capable of handling a small air-conditioning unit. Domino-format hobs (around 30 cm wide) are worth knowing about for galley kitchens or for homeowners who want to pair one induction zone with one gas burner. Common built-in cutout widths run at approximately 30 cm for domino, 60 cm for standard, and 75-90 cm for wider multi-zone configurations. Measure the available countertop run carefully, accounting for the frame and any drawer handles below, before you shortlist models. ## Mistake 4: Underestimating the Surface Ceramic glass looks sleek and wipes down in seconds after spills, which is genuinely one of the best things about induction. What is less often said is that the surface is rated for heat resistance, not scratch resistance. It handles a red-hot cast iron pan sitting on it without cracking. It does not handle sugar that has burnt onto the surface and then gets scraped with anything abrasive. Fine grit from a dirty pan base dragged across it leaves marks. This is not a dealbreaker, but it changes how you maintain the hob. Lift pans rather than sliding them. Keep the surface clean before you place anything on it. Use the specialist ceramic glass scrapers sold for this purpose when anything bakes on, not steel wool or rough sponge pads. Buyers who treat induction like a gas grate will find the surface looks tired within two years; buyers who understand the material will still have a near-pristine surface at six. ## Mistake 5: Confusing Portable Induction Cookers and Built-In Induction Hobs They are not interchangeable options on the same spectrum. They solve different problems. A portable induction cooker is a standalone tabletop unit. It plugs into a standard socket, requires no installation, costs considerably less, and is a genuine solution for renters, students, or households that want a secondary cooking point. The trade-off is that most portable units have a single zone, and even the better dual-zone portables have a shared power pool that limits simultaneous high-heat cooking. A built-in induction hob is set into the countertop. It requires a cutout to spec, hardwiring by a licensed electrician, and professional installation. It integrates cleanly with the kitchen design and typically offers more zones, more responsive power management, and better build quality at a given price point. Once it is in, it is in. The mistake buyers make is treating a portable unit as a "try before you buy" for the built-in decision. The two experiences are meaningfully different. If your kitchen layout and electrical supply support a built-in, and you cook regularly, the built-in is the correct choice. If you are in a rental or making a temporary arrangement, the portable is perfectly reasonable.

Induction converts roughly 85-90% of its energy directly to the pan, compared to a gas flame where a significant portion heats the surrounding air. For most households, the monthly electricity cost on induction is comparable to or lower than gas once you account for the full energy transfer. The upfront installation cost, including any circuit upgrade, is the larger variable to budget for. ### Can I use a cast iron pan on an induction hob? Yes. Cast iron is one of the best materials for induction: it is highly ferrous, holds heat well, and works across every zone setting. The main caution is weight. A heavy cast iron pot dragged rather than lifted across ceramic glass is how surface scratches happen. Place and lift carefully. ### How do I know if my kitchen needs a dedicated circuit for a built-in induction hob? As a starting point: a standard 13A socket in Singapore supplies roughly up to 3,000W. Most built-in four-zone induction hobs draw 7,000W or more, which exceeds that well. Even a two-zone model at 3,000-3,500W is at the limit of a single standard socket. Engage a licensed electrician to assess your kitchen's current supply before purchasing any built-in model. Do not assume the existing socket is sufficient. ### What is the typical cutout size for a built-in induction hob? Common cutout widths are approximately 30 cm for domino-format single or dual-zone hobs, 60 cm for standard four-zone models, and 75-90 cm for larger configurations. Every model has its own specific cutout dimensions in the spec sheet. Measure your countertop run and check the product spec before purchase, especially in a galley layout where there is no margin for error. ### Is there a difference between an induction hob and an induction cooker? In practical usage at retail, "induction hob" typically refers to a built-in countertop unit requiring installation and hardwiring. "Induction cooker" often refers to a portable tabletop unit that plugs into a standard socket. Both use the same induction technology, but they are designed for different living situations and have different installation requirements and power profiles. ## The Checklist Before You Click Buy Run the magnet test on every pot and pan in your kitchen. Check with a licensed electrician that your kitchen circuit will support the wattage of the model you want. Measure the countertop cutout and compare it to the spec sheet. Decide clearly whether your situation calls for a portable cooker or a built-in hob. Those four steps resolve almost every post-purchase regret that induction buyers report. Once you have done the checks, the decision gets straightforward. The **[induction hobs range](https://megafurniture.sg/collections/induction-hobs)** at Megafurniture includes models at multiple wattage and zone configurations, with product specs available to cross-reference against your kitchen measurements.
