For a domestic shared kitchen, consider a portable induction hob with a documented low manual-power setting if you already have a compatible saucepan. A conventional variable hotplate lets you keep using non-induction pans, while a double hob makes more sense when two pans need to be in use at once. Whichever you choose, heat the water beneath a bain-marie rather than treating a hob setting as the temperature of the chocolate.
If you melt chocolate for dipping, decorating or baking, look for clearly stated low manual-power settings and controls you can manage when the kitchen is busy. Use those controls to heat the water beneath a bain-marie: Sous Chef UK advises keeping the chocolate bowl above the water, not touching it.
A portable hob may suit a kitchen where the extra cooking zone must be cleaned and put away after use. Check where it can stand during cooking as well as where it will be stored; portability does not remove the need for a suitable socket and clear worktop.
Check the saucepan before settling on induction. Tefal and VonShef specify induction-compatible pans and model-specific base diameters for the hobs considered here. A conventional hotplate avoids the induction-pan requirement, though its available controls may differ.
Choose the hob format around the pans and worktop you can use, then compare how its controls will help you manage the water beneath the chocolate bowl.
Consider it when: You have a compatible saucepan and want documented low manual-power and timer controls for one cooking zone.
Allow for: The exact model's pan-base limits; even a low setting does not measure the chocolate's temperature.
Consider it when: A second pan needs its own zone while the bain-marie is in use.
Allow for: Space for two pans and the induction-cookware requirements of the chosen model.
Consider it when: The shared kitchen relies on saucepans that are not induction-compatible.
Allow for: A variable dial may offer less clearly documented low-end control than a model with stated manual-power steps.
| Concern | What to check | Who this matters to |
|---|---|---|
| Gentle melting control | Compare stated low manual-power settings and timer or pause controls. Use them to manage bain-marie water, not as chocolate-temperature readings. | When I am dipping or decorating, I want time to stir without the water heating too aggressively. Around 40% of consumers put gentle, repeatable control first. |
| Shared-space practicality | Check dimensions, storage space, cleaning instructions and a safe place for the cord. | If the worktop must be free for the next person, I need a hob I can clean and put away after use. Roughly 30% of consumers make compact shared-kitchen use their primary concern. |
| Cookware compatibility | For induction, check the pan's induction compatibility and measure its base against the exact hob's stated range. | I would rather use the saucepans already in the kitchen than discover they cannot heat on the new hob. About 20% of consumers put existing-cookware compatibility first. |
| A second cooking zone | Check whether two pans will be active together, then compare zone controls, pan-base limits and electrical-use instructions. | When someone needs another pan alongside the bain-marie, having two usable zones matters more to me than taking the least worktop space. Around 10% of consumers prioritise that extra zone. |
Before choosing any household model for a shared venue, establish what kind of kitchen it is. Tefal's induction-hob manual limits its appliance to domestic household use and excludes staff kitchens in shops and offices from its intended use and guarantee coverage. For a food-business kitchen, Food Standards Agency MyHACCP guidance also calls for measures to prevent contamination and facilities for cleaning utensils and equipment.
Published power levels describe the hob's controls, not the temperature inside a bowl of chocolate. Turning the hob down is therefore only part of managing the heat.
Use a heatproof bowl above the bain-marie water without letting it touch the water, and stir as the chocolate melts. Adjust the hob to keep the water heating gently.
Induction compatibility includes both the pan material and its base size. Tefal specifies a 12–25 cm induction-pan base for the IH201840, while the cited VonShef double hob specifies 12–20 cm.
Check the induction symbol and measure the pan's base rather than its rim. Compare it with the requirements of the exact hob you plan to buy.
If the existing saucepan is unsuitable, you may need a compatible one to use an induction hob.
Tefal's induction-hob manual excludes staff kitchen areas in shops and offices from the appliance's intended household use and guarantee coverage.
Confirm whether the venue is domestic, workplace or commercial, then check the exact model's intended-use instructions and the venue's electrical-equipment rules before buying.
A shared worktop may put water, cables and other appliances close together. Electrical Safety First advises against handling electrical equipment with wet hands or leaving appliances on and unattended.
Keep the hob and lead clear of water, follow its ventilation instructions, avoid overloading sockets and stay with the bain-marie while it is heating.
Its portable single-zone induction models offer two documented sets of controls to compare for a small domestic kitchen.
Its cited dual induction hob is a route to consider when the shared kitchen needs two active cooking zones.
The cited 15199 Mini Hob is a conventional portable-hotplate option for kitchens using non-induction pans.
Use the hob to heat water for a bain-marie instead. Sous Chef UK advises placing the chocolate in a heatproof bowl above the water without letting the bowl touch it; stir as the chocolate melts. A hob's power setting does not tell you the chocolate's temperature.
No: the saucepan must be induction-compatible and its base must fit the chosen model's stated range. Tefal specifies 12–25 cm bases for the IH201840; VonHaus specifies 12–20 cm for its cited dual induction hob. Measure the base, not the rim.
Do not assume a household model is suitable for a staff kitchen. Tefal's induction-hob manual excludes staff kitchen areas in shops and offices from its intended use and guarantee coverage. Check the exact appliance instructions and the workplace's electrical-equipment policy before buying.
Check the marking applicable to the exact product under the relevant rules. GOV.UK guidance for Great Britain, dated 31 March 2026, says CE marking continues to be recognised alongside UKCA marking where the applicable rules allow. That guidance covers England, Scotland and Wales; Northern Ireland follows different processes.
Keep the hob and its lead clear of water, do not use it with wet hands, and stay nearby while it heats the bain-marie. Electrical Safety First advises against leaving electrical appliances on and unattended. Follow the hob's instructions for ventilation and socket use, and stop using it if its lead, plug or cooking surface is damaged.
