Wanted to Replace My Old Gas Cooktop

Hi. I have had a very old cooktop since I moved to this house.
I searched to replace a new cooktop but it looks like I need to replace the tabletop.
Before that, cut out of My cooktop size is 890mmx375mm however most 900mm cooktop doesn't fit on my table top.

Can someone have an idea to replace a cooktop without a new tabletop?

Thank you so much in advance.

    Wanted to replace my old gas cooktop.

    Better hurry before Dan announces that all new gas appliances are banned

      Yes, I feel I need to replace it beforehand.

        I'm going to start stockpiling gas appliances in the garage so I'm not caught short…

          Good luck with your humongous gas bills when you are the last one on the network.

                    Now Dan is going after vulnerable kids because they are easy targets for him…

                    • @jv: Your logic.. Thankfully Dan doesn't take your advice.

                      • @Aureus:

                        Your logic.

                        Actually, it is Dan's logic…

                        He believes kids with vision and hearing impairments do not need extra help.

        Reminds me of the black-market plumber from the movie Brazil. Looks like that's where we're heading.

        Soon you won't need a cooktop.
        Next he will be banning meat and real food.
        You will be supplied with very convenient and environmentally friendly ready to eat food rations prepared with lab grown meat and insects flour. Ingredients will also include all necessary vaccines to keep you healthy. That way you will not need to leave your habitation pod provided to you by the government.

      Aren't they just banning gas pipes being laid to new subdivisions?
      It makes economic sense. Gas heating is very inefficient, and the days of dirt-cheap gas are over.
      If you just want gas for cooking, you can use bottled. 9kg will last many months if not years.

      • Aren't they just banning gas pipes being laid to new subdivisions?

        No, anything that requires a building permit must not include gas pipelines.

        you can use bottled.

        Don't want a gas bottle in the house, and I prefer gas heating and gas hot water.

        • Have you really never seen a house with bottled gas? Nobody puts the bottle indoors for obvious reasons.

          No, anything that requires a building permit must not include gas pipelines.

          Wow! That is drastic.

            Dan is just only starting on this….

            The faster he brings all this crap in, the more he 'benefits'…..

    • You could always umm buy them from interstate like people do with Koi fish.

    So your 600mm deep benchtop has an 890 x 375mm cutout? How about this one?

    • It looks not bad but why only 3 burners? :)

      • +2

        Because the cutout is only 375. If you can cutout to 470 you can have five burners.

  • +1

    Most electric/induction cooktops have a larger benchtop cutout than gas.
    Nothing stopping you getting the existing cutout enlarged to fit a new cooktop.

    Did it recently to replace an old gas cooktop with induction (even before jv was ranting about them being banned, though if I'd included jv ranting in my ROI calculations I'd me miles ahead)

    • +3

      Not everybody is a fan of induction.

      • +3

        Interestingly, most of those people have never used induction and/or haven’t used any form of electric cooktop made in the last 10 years.

        • -1

          Because they know it will be crap for wok cooking…

          • @jv: Sure. But induction is better for most other things, and it’s safer and quicker, so unless you’re using a wok several times a week (when yes, full gas would make sense), you can always get a single burner and hook it up to a gas cylinder for the times you do want to use a wok.

            Note: add gas cylinders to your stockpile, jv.

            • @jjjaar:

              I like wok cooking…

              No room for those and I'm sure Dan will ban them too…

            • @jjjaar: "But induction is better for most other things"
              except in our case, the majority of out pots & pans.
              we moved house not long after buying a whole new set, the cooktop is 50/50 induction and normal
              .

            • -1

              @jjjaar: Nah induction has terrible heat distribution unless you've got a top of the line stove. Rather than repeat myself see my comments in in this thread

              • +1

                @Cheaplikethebird: Don't need a top of the line stove. Just buy a good one and read reviews. I have used a fairly new middle range Bosch cooktop, that doesn't have any of the issues in the linked video.

                • +1

                  @Aureus: Works with a 12" pan?

                  Unfortunately I'm a renter so 'good' stoves don't exist in my world only the absolute cheapest.

                  • +1

                    @Cheaplikethebird: Yeah. Works fine with a large pan.

                    I do get that you can get a cheap gas stove with no research and it should be fine, but Induction is great if you DYOR.

        • Nope, but they have paid electricity bills.
          Or did I miss the graph saying those prices are heading south (ever again).

      • Electromagnetic induction for cooking? I concur.

        Philosophical induction for figuring you out? One of my most favorite pastimes while on this site.

  • Is your cutout too small or too big?

    If it’s too big, you can put in a stainless steel sheet to surround the new cooktop. (This is an American company but shows you what it can look like https://microtrim.com/cooktop-trim-kits/)

    If it’s too small, what material is it, and can you cut into it?

    • My cutout is 890mmx375mm so 890mm is too big; most 900mm cut out is 840mm~850mm and 375mm is a bit small.
      The stainless steel sheet looks quite good to me but I wonder how much will be haha.
      Anyway Thank you for your help

  • Cut the width of the benchtop to suit the new cooktop.

    The larger existing width of the hole shouldn't matter, you have a 5mm overlap on each side. If you are concerned about larger hole, pack one side with a 40mm wide piece of timber under the cooktop.

    I'd recommend the Bosch 900mm series 6 6 burner gas cooktop. 2 wok burners with 19.5 Mj/h output.

    • Are all gas lines the same capacity (can run multiple outlets at once with no pressure/flow losses) ?

      • For cooking yes.

        Only instant gas hot water systems require a larger gas line

  • Is there a way to measure the cooktop cut out without removing the existing cooktop? I've tried to search the model name and number for existing cooktop but struggling to find the information.

    • I am searching for this too….. blah
