Induction vs Gas Hob in Singapore: Cost, Power and Which to Install
Induction vs gas hob in Singapore: compare running cost, power needs, wok cooking and installation so you can pick the right hob for your HDB or condo kitchen.
For most Singapore homes an induction hob is the safer, faster and easier-to-clean choice, while a gas hob still wins for high-heat wok hei and homes that already have a town gas or LPG supply. Induction is more energy efficient and cooler to the touch, but it needs a dedicated 20A or 32A power point and only works with magnetic (ferrous) cookware. Gas gives instant visible flame and works with any pot, but adds heat to the kitchen and needs a gas point plus good ventilation.
The right answer depends on your kitchen more than the technology. In a compact HDB flat with an existing town gas riser, keeping gas can be the cheaper path. In a condo or a renovated flat with no piped gas, induction is usually the natural fit because you are wiring the kitchen anyway. This guide breaks down running cost, power and installation for Singapore conditions so you can decide before you commit to carpentry and wiring.
What is the real difference between induction and gas?
A gas hob burns town gas (piped, from City Energy) or bottled LPG to produce an open flame under the pot. An induction hob uses an electromagnetic coil to heat the pot itself directly, so the glass surface stays relatively cool and only the pan gets hot.
The practical differences homeowners feel every day:
Induction vs gas: quick comparison
Here is how the two stack up for a typical Singapore kitchen:
- Speed: Induction boils water fastest; gas heats fast but loses energy to the air around the pot.
- Efficiency: Induction transfers roughly 85 to 90 percent of energy to the pot; gas is closer to 40 to 55 percent, so more heat escapes into your kitchen.
- Cookware: Induction needs magnetic pots (a fridge magnet should stick); gas works with any pot including clay pots, woks and older aluminium pans.
- Heat and comfort: Induction keeps the kitchen cooler, which matters in Singapore's climate; gas raises room temperature and works your aircon or fan harder.
- Cleaning: Induction is a flat glass surface you wipe down; gas has grates and burner caps to remove and scrub.
- Safety: Induction has no open flame and auto-shuts when the pot is removed; gas carries a small leak and flame risk and needs ventilation.
- Power cut: Gas keeps working in a blackout; induction does not.
Which is cheaper to run in Singapore?
On a per-unit-of-heat basis, induction is usually more efficient, but town gas is often priced attractively, so real running cost is close for many households and depends on how much you cook. Electricity is billed per kWh and town gas per kWh of gas, and both tariffs change quarterly, so check your latest SP Group and City Energy rates rather than trusting an old number.
Upfront, a basic induction or gas hob can start from around S$300 to S$600, with premium built-in models running well above S$1,000. Factor in installation and, for induction, possible electrical upgrade work. Treat these as ranges only and confirm current prices with the retailer, since promotions and models change often.
Does induction need special wiring or power points?
Yes. A full-size induction hob draws a lot of current, so it usually needs its own dedicated circuit and a 20A or 32A connection unit rather than a normal 13A wall socket. This is the part homeowners most often overlook, and it is exactly why the hob decision belongs in your renovation planning, not after.
Points to confirm before you buy:
- Check the hob's rated power (often 3kW to 7kW total) against the connection point your kitchen has.
- A dedicated circuit from the distribution board is typically required for larger induction hobs.
- Portable single-zone induction cookers are the exception; they run off a standard 13A socket and suit rental units or as a backup.
- Any new circuit or consumer-unit work in Singapore should be done by a Licensed Electrical Worker and comply with SP Group requirements.
What about wok cooking and hawker-style heat?
If your cooking leans heavily on stir-frying, high-heat searing and that smoky wok hei, a gas hob with a strong burner is still the traditional favourite because the flame licks up the sides of a round-bottom wok. Many Singapore cooks keep gas for exactly this reason.
That said, induction has closed the gap. Dedicated induction wok burners with a curved recess now exist, and they deliver strong, controllable heat with far less ambient warmth. If you want the induction convenience but still stir-fry often, look for a model with a high-power booster zone or a purpose-built wok zone.
Planning the hob into your renovation
Because both options touch your kitchen carpentry and services, the smart move is to decide early and build around it. Induction needs the right power point and a cabinet cut-out with ventilation clearance below; gas needs a gas point, a safe connection and good extraction above. Getting these wrong means reopening finished cabinetry later.
This is where coordinating your renovation, electrical and plumbing works together pays off. When the same team plans the wiring points, the gas or water connections and the cabinetry cut-outs in one go, you avoid clashes between the electrician, the carpenter and the hob dimensions. If you are renovating a kitchen, map the hob choice into the layout and points plan before the carpenter builds, and have a licensed professional handle the electrical or gas connection.
So which hob should you install?
Choose induction if you want lower heat in the kitchen, easy cleaning, faster boiling and a safer surface, and you are already rewiring or have capacity for a dedicated circuit. Choose gas if you cook with a wok constantly, want an instant visible flame, already have a town gas supply, or want a hob that still works in a power cut.
Many Singapore homeowners now compromise with a dominant induction hob plus a single gas burner or a portable gas stove for occasional wok work. Whatever you pick, size the power or gas point and the cabinet opening correctly, and confirm current model prices and tariffs before you buy.
Frequently asked questions
Can I switch from gas to induction in my HDB flat? Yes, this is common. The main task is electrical: a full induction hob usually needs a dedicated circuit and a 20A or 32A point, which should be installed by a Licensed Electrical Worker. You can also cap off or keep the existing gas supply, but any gas work should be handled by an approved gas service worker.
Do I need to buy new pots for an induction hob? Often yes. Induction only works with magnetic cookware, so test your pans with a fridge magnet; if it sticks firmly to the base, the pan will work. Many stainless steel and cast iron pieces are compatible, while most aluminium, copper and clay pots are not.
Is induction safe if I have young children? It is generally safer than gas because there is no open flame, the surface cools quickly once the pot is removed, and most hobs have a child lock and auto-shutoff. You should still supervise, since the pan itself and residual heat on the glass can still burn.
Which is faster, induction or gas? Induction typically boils water faster and offers more precise low-heat control, because it heats the pot directly with little wasted energy. Gas responds instantly when you adjust the flame but loses more heat to the surrounding air.
