Choose a portable single-zone induction hob if sauce is your only active pan and you need to clear the worktop after cooking. If you regularly boil pasta while simmering sauce, a narrow built-in two-zone hob gives each pan a zone, but it permanently occupies worktop space and needs suitable installation. Either choice also depends on having compatible pans.
If you mainly use one saucepan for sauce and need to put the hob away afterwards, a portable model is worth considering. Check that your pan has a magnetic base and falls within the model's stated size range. Tefal positions its IH210840 for small kitchens and storage between uses.
If both pans need heat at the same time, consider a narrow built-in two-zone hob where a permanent installation will fit. The product information lists the two-zone CDA SCN030FR at 28.8 cm wide; its width alone does not establish whether it fits your worktop or electrical arrangement.
A portable hob can provide one additional cooking position alongside your main setup, then be stored. It does not provide two independently usable zones on its own.
Decide how many pans must cook at once before choosing between a removable appliance and a permanent installation. Then check the space and cookware requirements of the exact model.
| Concern | What to check | Who this matters to |
|---|---|---|
| Worktop space and storage | Measure the clear surface needed during use and the space available for storage. For a built-in hob, use its exact cut-out and clearance instructions rather than its advertised width alone. | When I make sauce in one pan, I want the worktop clear again afterwards; around 42% of consumers put footprint and storage first. |
| Cooking two pans together | Check the number of independently usable zones and any power-management conditions when more than one zone is running. | If I boil pasta while sauce simmers, each pan needs its own zone. Around 33% of consumers make simultaneous cooking their primary concern. |
| Sauce control and pan fit | Check the available heat settings and whether each intended pan has a magnetic base within the hob's permitted size range. | I need my saucepan to work on the hob and want settings suited to the sauce I cook; for around 25% of consumers, control and cookware compatibility come first. |
A single portable hob can heat sauce, but it cannot independently boil pasta at the same time. Without another cooking position, you would need to use the hob sequentially.
Count the pans you normally heat together. Choose one zone for sauce-only or occasional extra-zone use; consider two zones if cooking both pans together is routine.
Induction requires a magnetic pan base, and a portable hob may also specify minimum and maximum pan dimensions. Tefal, for example, states a 12–26 cm induction-pan diameter range for the IH210840.
Check each intended pan with a magnet and compare its base dimensions with the exact hob's instructions, rather than relying on the diameter across the rim.
If your existing saucepans are unsuitable, you may need compatible cookware.
A compact width does not settle the cut-out, ventilation, clearance or electrical requirements. General guidance calls for space around an induction hob, while the exact model's installation instructions determine its fit.
Check the installation drawing against your worktop and confirm the electrical arrangement before buying. If fitting is needed, establish what worktop alteration and connection work it involves.
In a 2025 report, the UK Office for Product Safety and Standards identified a serious fire risk in one induction cooker whose plug lacked a fuse link conforming to BS 1362. The report concerns that product, not portable induction hobs generally.
Keep the exact product details, inspect the plug and lead before use, and check current safety notices if the appliance's identity or condition raises concerns.
Portable single-zone induction hobs for kitchens where the cooking appliance needs to be stored after use.
Narrow built-in induction for cooks who need two zones without choosing a conventional 60 cm hob.
Built-in induction options for a permanent kitchen setup, including standard-width multi-zone models.
These choices cover two ways to cook in a small kitchen: a narrow built-in hob for pasta and sauce in separate pans, and a portable single-zone hob for sauce-only cooking or an occasional extra zone. Check which arrangement fits your worktop and how you cook before comparing their controls.

Consider this fixed two-zone layout if pasta and sauce need separate cooking positions. The model is listed at 2900 W with nine power levels, a timer and a child lock.
Check the cut-out, ventilation and electrical connection against the exact installation instructions before buying.

Consider this portable single-zone model when sauce is your only active pan and you need to put the hob away after cooking. Its listed features include 10 power settings, six functions and a safety lock.
Check your pan-base compatibility, the appliance's dimensions and its plug details before buying. Keep its ventilation openings clear during use; one zone cannot heat pasta and sauce independently at once.
Yes, if you need to heat only the sauce pan on that hob and can cook pasta elsewhere or at another time. If you regularly want both pans cooking independently together, choose a two-zone arrangement rather than relying on one portable zone.
It will work only if its base is suitable for induction and fits the chosen hob's permitted pan dimensions. Bosch specifies magnetic cookware for induction; check your saucepan with a magnet and consult the exact model's pan-size guidance before ordering.
The connection requirements depend on the exact model and kitchen installation. The product information states that the CDA SCN030FR is supplied with a plug and does not require an electrician, but that statement does not apply to every compact hob; a built-in model still needs the specified cut-out, ventilation and suitable electrical provision.
Check that the plug, lead and socket are in good condition, avoid overloading sockets and keep electrical fittings away from the sink. Electrical Safety First advises a horizontal separation of at least 30 cm between sockets or switches and the sink where possible. Stop using an appliance if its plug, cable or socket shows damage or overheating.
No. Although induction heats the pan directly, the pan and the glass beneath it can still be hot. Treat the cooking area as hot until it has cooled and follow the appliance's instructions.
