For one stockpot and limited worktop space, start with a portable single-zone induction hob if your pot has a compatible base and the model offers the heat settings you need for simmering. A slim model may be easier to store; choose a twin conventional electric hotplate instead if you need a second pan or want to keep using cookware that is unsuitable for induction, accepting its larger footprint.
If you cook stock in one pot and put the hob away afterwards, a single portable zone keeps the appliance choice focused on your available worktop and storage space. Check that its controls let you move from a boil to a gentler simmer.
Measure the pot’s flat base before choosing induction. Its compatibility and base diameter matter more than whether the pot’s rim appears to fit over the hob.
A twin conventional electric hotplate is worth considering if your existing pot is unsuitable for induction or you need another pan beside the stockpot. Allow enough clear worktop for the whole appliance.
Start with the space available while cooking, then check your stockpot and the controls you will use after the stock reaches a boil. A second ring is useful only if it earns its place on the worktop.
| Concern | What to check | Who this matters to |
|---|---|---|
| Worktop and storage space | Check the full length, width and thickness, plus where the pot and cable will sit. | If the stockpot is my only pan, I want room left for preparing vegetables and somewhere to put the hob afterwards. Around 42% of consumers put space first. |
| Boil-to-simmer control | Look at the manual heat settings and any conditions attached to boil presets; a timer is not a reason to leave stock unattended. | When I make stock regularly, I need to lower the heat after boiling rather than rely on a preset for the whole cook. For around 33% of consumers, control is the primary concern. |
| Cookware and extra pans | For induction, check that the flat base is magnetic and within the model’s stated size range; for two zones, measure the complete unit. | If I need to keep using my stockpot or heat another pan alongside it, that flexibility may matter more than saving space. It is the main priority for around 25% of consumers. |
A wide rim does not tell you whether the flat base is magnetic or falls within a hob’s compatible size range.
Test the base with a magnet, measure its flat diameter and compare both with the exact model’s cookware guidance.
If the existing stockpot fails those checks, choosing induction may mean changing the pot.
Tefal specifies the IH201840 boil programme for 1.5 litres in a 20 cm pan. That setting does not establish suitable timing for a larger stockpot.
Stay with the pot during the initial boil, then choose an appropriate manual setting for simmering and continue to supervise it.
The Duronic HP2 BK is 54 cm long. Its second ring may be useful, but the complete unit could take space needed for preparation.
Mark out the appliance and pot positions before buying, and choose one zone if you do not need to cook with a second pan.
Portable single-zone induction models include the IH201840 and the slimmer IH210840.
A single-zone induction option with manually selectable settings.
A twin conventional electric hotplate option for cooking with two pans or avoiding an induction-cookware requirement.
These portable induction hobs suit a one-pot setup if your stockpot is compatible. Compare their stated controls and cookware requirements, then check the full dimensions against your worktop and storage space.

Consider this single-zone hob if you need to store it between stock batches and want adjustable settings for cooking in one pot.
The product title states eight power levels, 60–270°C temperature control, seven preset functions, a three-hour timer and suitability for 12–26 cm cookware. Check that your stockpot’s flat magnetic base fits, and confirm the hob’s full dimensions and cable position before ordering.

This single-zone option is relevant if you cook stock in one induction-compatible pot and want a hob you can put away afterwards.
The product title lists ten power settings, six functions, touch controls and a safety lock. Before choosing it for a long simmer, check its lowest setting, compatible flat-base diameter and full dimensions. Keep its ventilation openings clear and do not leave it unattended.
It can work if its flat base is induction-compatible and falls within the chosen hob’s permitted size range. Check whether a magnet sticks to the base, then measure that base rather than the pot’s rim; Tefal’s IH201840 listing, for example, gives a compatible pan-diameter range of 12–26 cm.
No: use a boil programme only within its stated conditions and supervise the pot. Tefal describes the IH201840 programme for 1.5 litres in a 20 cm pan, so do not treat it as a cooking schedule for a larger batch of stock.
Choose a twin hotplate when you need another pan alongside the stockpot or want to use cookware unsuitable for induction. The Duronic HP2 BK offers two cast-iron rings but is 54 cm long, making its worktop fit an important part of the decision.
