Who each format suits

One-pan vegetable blanchers

If you boil one saucepan of water for greens and put the hob away afterwards, a one-zone induction model is worth considering. Check that your saucepan is induction-ready and meets the chosen hob’s pan-base requirements.

Buyers keeping their existing pans

If your saucepan is aluminium, copper or non-magnetic stainless steel without an induction base, compare conventional electric hotplates. VonHaus lists those materials as compatible with its double hotplate; an induction hob requires suitable magnetic cookware.

Small-kitchen multitaskers

If you need to blanch greens while heating a second pan, consider a two-zone portable hob. Measure the available worktop first: the extra zone is less useful when you normally cook with one saucepan.

What to check before buying

One-zone induction

Choose it when: you blanch one pan at a time and have an induction-ready saucepan.

Trade-off: an unsuitable or incorrectly sized pan may need replacing.

Conventional electric hotplate

Choose it when: keeping a non-magnetic saucepan is a priority; VonHaus lists several such materials as compatible with its double hotplate.

Trade-off: that double-hotplate example needs more worktop space than the compact single-zone Judge induction model.

Two-zone induction

Choose it when: another pan must run while you blanch the greens.

Trade-off: it takes up more space, and both pans must be induction compatible.

Concern What to check Who this matters to
One-pan heat control Compare stated power or temperature settings and any timer you want. Rated watts alone do not establish which hob boils a saucepan faster. When I blanch one pan of greens, I want to adjust the heat as needed rather than choose by maximum wattage alone; around 40% of consumers put controllable one-pan boiling first.
Worktop and storage space Measure the usable surface, leaving room for the pan handle, cord and draining. Compare the model’s dimensions with your storage space. I need to clear the worktop after cooking and cannot spare space for an extra zone. Roughly 30% of consumers make a small footprint and easy storage their primary concern.
Existing-pan compatibility Check the pan maker’s induction guidance, whether a magnet adheres to the base and the hob’s permitted base diameter. Otherwise, compare a conventional hotplate. If my current saucepan will not work on induction, I would rather consider a compatible hob than replace a usable pan; around 30% of consumers prioritise keeping their cookware.

Buying pitfalls

  • Ordering an induction hob before checking the saucepan

    An induction hob may not heat a non-magnetic pan, and the pan base must also meet the model’s size requirements.

    Check the saucepan’s induction marking and base diameter against the exact hob’s instructions; a magnet on the base is a useful initial check.

    You may need a separate induction-ready saucepan if the one you use for blanching is unsuitable.

  • Assuming a portable hob can be set up anywhere

    IKEA’s TILLREDA instructions prohibit extension cords and routing the cord across working areas. Electrical Safety First warns that overloaded extension equipment can overheat and cause fire.

    Use a clear, stable worktop and follow the instructions for your exact appliance and its electrical connection.

  • Choosing two zones without measuring the counter

    A second zone helps when two pans are needed, but a double unit can occupy space needed for the saucepan handle and for draining vegetables.

    Measure the usable worktop and compare appliance dimensions before choosing the extra zone. VonHaus lists its conventional double hotplate at 46 × 28 cm, while Judge lists its single-zone JEA90 at 31 × 27 cm.

  • Treating rated wattage as a blanching-speed result

    Manufacturers’ wattage figures describe their models, not the result of a like-for-like boiling test. Pan choice, water quantity and settings also matter to the task.

    Use the rating alongside pan compatibility, available controls and physical fit, rather than assuming the highest stated wattage settles the choice.

Brands to consider

Tefal

Its IH201840 is a single-zone induction option for buyers comparing heat settings and saucepan requirements.

  • Tefal lists nine power levels, from 450 W to 2,100 W, and a timer of up to two hours for this model.
  • It requires induction-ready cookware; confirm the stated pan-base range against your saucepan.

IKEA

The portable TILLREDA range includes one- and two-zone induction formats for different pan counts.

  • IKEA describes its one-zone model as easy to move and stow away.
  • TILLREDA instructions prohibit extension cords and placing the cord across working areas; check the manual for the model you choose.

Judge

Its JEA90 gives buyers published measurements to compare with a small worktop and storage space.

  • Judge lists the JEA90 at 31 × 27 × 5 cm and 2.4 kg, with ten selectable temperatures from 60°C to 240°C.
  • Judge’s induction guidance requires magnetisable pans.

VonHaus

Its published range offers examples of both portable induction and conventional electric hotplates.

  • VonHaus lists aluminium, copper, cast iron and non-magnetic stainless steel as compatible with its conventional double hotplate.
  • That double-hotplate format needs more counter space than a compact single-zone model; compare dimensions for the exact appliance.

Frequently asked questions

Will my saucepan work on a portable induction hob?

It needs an induction-compatible magnetic base and must meet the exact hob’s pan-size requirements. Judge says induction pans must be magnetisable; check your pan maker’s guidance and the hob instructions as well as trying a magnet on the base.

Do I need one zone or two to blanch vegetables?

One zone is sufficient when you use a single saucepan for the blanching task. Consider two zones if another pan needs heat at the same time, provided the larger appliance fits your worktop and, for induction, both pans are compatible.

Can I use an extension lead with a portable hob?

Follow the instructions for the exact hob: IKEA says not to connect its TILLREDA hob using extension cords. Electrical Safety First warns that overloaded extension leads, reels and adaptors can overheat and cause fire, so do not treat portability as permission to use an unsuitable electrical setup.

What if an induction hob’s glass surface is cracked?

Do not continue using a cracked hob. IKEA’s TILLREDA instructions say to switch off a cracked surface to avoid possible electric shock; follow the appliance instructions for obtaining qualified help.

What electrical-product information should I check before buying?

Check the appliance instructions and the product-marking and compliance information applicable where it will be supplied. The Office for Product Safety and Standards says the Electrical Equipment (Safety) Regulations 2016 set requirements for equipment placed on the Great Britain market; provisions can differ in Northern Ireland, so confirm the applicable information with the retailer or manufacturer if that is your destination.
