Cooktops

Induction heats the pan directly through a magnetic field, so it responds fast and the glass stays cooler. It needs induction ready cookware. Ceramic cooktops heat elements under the glass and work with any flat bottomed pan, but take longer to heat and cool.

Measure the existing hole in your benchtop and check it against the cut-out size listed on the product page, which is smaller than the cooktop overall size. If the new cut-out is bigger, the bench may need to be recut by a professional.

Some smaller and portable cooktops plug into a standard power point. Larger electric and induction cooktops usually need to be hardwired by a licensed electrician. Check the power rating and plug details on each listing.

It depends on the model. Check which gas type each model is set up for and whether LPG conversion parts are included. Check the listing, and have a licensed gas fitter install and convert it if needed.

You need cookware with a magnetic base, such as cast iron or stainless steel marked induction ready. A quick test is to see if a fridge magnet sticks to the base. Aluminium, glass and copper pans will not work unless they have an induction base.

Two zones suit small households or a backup cooktop. Four zones is standard for families, and wider cooktops give more space between pans. Check the number and size of zones on each listing.

Features to look for include child locks, residual heat indicators and auto shut off, plus flame failure protection on gas models. Check the product details for the specific features on each model.
