Gas Cooktops

Robam gas cooktops are built for high heat. Max burner power runs from 17MJ to 23MJ, so a wok stays hot enough to sear instead of stew and a full stockpot reaches the boil without the wait. Choose a 60cm, 86cm or 90cm gas cooktop in tempered glass or stainless steel, with three, four or five burners.

Don’t assume a smaller cooktop means less firepower. The 60cm 7B7H32 has the same 23MJ main burner as the 9B7H31F 90cm gas cooktop, while the 90cm five-burner B520 tops out at 17MJ. Width and burner count tell you how many pans fit; max burner power tells you how hot the biggest flame gets.

Want a flat surface with nothing to lift off for cleaning? Compare our induction cooktops. Already know your layout? Go straight to 3 burner, 4 burner or 5 burner gas cooktops. Finish the cooking zone with a rangehood, and keep cooktop spare parts on hand for trivets, burners and knobs.

Buying Guide

Size — Will it fit your benchtop?

Gas cooktops in this range come in 60cm, 86cm and 90cm widths; use the Size filter to narrow them down. Measure the hole in your benchtop, not the old cooktop, and check it against the cutout size in each product’s spec table. Cutouts vary even between models of the same width: the 9B7H31F needs 827 × 480mm, while the B510 needs 840 × 480mm.

Burners — How many pots do you cook at once?

Filter by Number of Burners. Three-burner models make up most of the 23MJ range, which suits cooks who wok-fry most nights. Four-burner models are all 60cm, for compact benchtops that still need four pans going. Five-burner models come in 86cm and 90cm widths for larger households and entertaining.

Burner power — How hot does your wok burner need to be?

Use the Max Burner Power filter to choose between 17MJ, 18MJ, 22MJ and 23MJ. This figure is the strongest single burner, rated in megajoules per hour (MJ/h). The spec table also lists total gas output across all burners, for example 52.5MJ/h on the 9B7H31F. If you stir-fry or sear often, start with the 23MJ options.

Material — Tempered glass or stainless steel?

Filter by Material. Tempered glass models have a smooth top that wipes clean and come in the widest choice of colours. Stainless steel models, such as the G411 and ZG81H60, come in 60cm and 86cm widths and suit kitchens with steel appliances or a more traditional look.

Colour — Which finish suits your kitchen?

The Colour filter covers Glossy Black, Glossy White, Matte Grey and Matte Black. The white, grey and matte black finishes are all three-burner glass models, so choose your finish and burner count together.

Budget — Which features are worth paying for?

Set a range with the Price filter. Entry models such as the B420 and G411 cover the essentials: electric ignition, dual brass burners and flame failure protection. Step up to models like the 9B7H31F and 7B7H32 for a 23MJ main burner, a cooking timer and R-Link sync with a compatible rangehood.

Frequentyl Asked Questions

What size gas cooktop do I need?

Measure the cutout in your benchtop, then use the Size filter on this page to see 60cm, 86cm and 90cm models. A 90cm gas cooktop fits up to five burners, while a 60cm model suits compact kitchens. Always confirm the cutout size in the spec table before you buy.

Can I replace my old cooktop without recutting the benchtop?

Only if the cutouts match. Compare your existing cutout with the figure in each spec table: the 7B7H32 needs 560 × 480mm and the B420 needs 555 × 475mm, so two 60cm models can still differ. If the numbers don’t line up, ask your installer before you order.

What does MJ mean on a gas cooktop?

MJ/h (megajoules per hour) measures how much gas a burner uses at full flame, which is a guide to its heat output. The Max Burner Power filter shows the strongest burner on each model, from 17MJ to 23MJ. For regular wok cooking on a 90cm gas cooktop, look at 23MJ models such as the 9B7H31F.

What is R-Link?

R-Link is Robam’s Bluetooth link between cooktop and rangehood. The rangehood turns on and off with the cooktop, so extraction starts when you start cooking. It needs an R-Link cooktop and a compatible Robam rangehood; check the R-Link row in both spec tables.

Which gas cooktops have a cooking timer?

Check the Timer Function row in the spec table. The 9B7H31F and 9B1H33 have a timer of up to 180 minutes that shuts off the flame and gas supply when time is up. The 7B7H32 also has a timer.

Can I buy replacement trivets and burners?

Yes. Our cooktop spare parts range includes cooktop trivets, wok trivets, burners and control knobs. Have your model number ready (it’s the SKU on the product page) so you order the part that fits.
