Operate a gas stove without a household connection using a gas cylinder?

Good evening,
we have started planning our kitchen and want to provide an 80 or 90 cm induction cooktop. Now I have come across slim gas cooktops, e.g. the Siemens iQ700 ER3A6BD70D, and I am wondering if that could still be a nice addition. The development area where we will be building is new, and we were told that a gas line is also planned there. However, for the building services we are not planning to use gas, and I strongly suspect that a gas connection just for such a cooktop will never pay off, since normal connection fees, meters, etc. would also have to be paid. Therefore, I wonder if it is possible to operate the cooktop, for example, with an 11 kg gas bottle that is either placed outside on the house wall through a conduit, e.g. in a small shelter, or positioned in a corner of the kitchen in the base cabinets.

According to the internet (e.g. in the blog of the gas accessories supplier GOK), this seems to be possible. Has anyone here already gained practical experience with this, or is it nice in theory but nonsense in practice? Many thanks!

In other countries, this is completely normal. But I don't know how the regulations in Germany are regarding having such gas bottles indoors. You will also always want to have a bottle in reserve. I haven't noticed any difference when it comes to cooking.

Are you really that professionally inclined when it comes to cooking? I briefly chatted with my husband about it, who used to cook in the gastronomy industry, about why one would prefer gas over induction. It really sounded like very specific use cases in cooking. Is it really worth the extra effort to deal with the gas bottle for that? In other countries, this is probably done more often, but personally, I wouldn't go through the hassle. You have the big advantage of "instant heat" with induction just like with gas. Besides, with an induction cooktop, the cleaning effort is significantly less. Cleaning a gas stove is no fun. o_O

Well, gas is still a bit easier to control. With induction, too much depends on the pots and pans. I had also considered incorporating gas, but ultimately admitted to myself that I don’t cook that often or elaborately.

Hello, well that fits the theme perfectly. Just last week, we had gas lines installed from the external utility room into the kitchens in 2 of the 4 residential units of a newly built (almost finished) semi-detached house so that we can cook with gas there. In each half of the utility room, there is then an 11kg gas cylinder. The effort is so-so. Each connection costs us a flat rate of €500. I hesitated briefly at that price, but cooking with gas was important to me. Included in the price: laying gas hoses in protective conduits, connection both in the utility room and in the kitchen unit. The only condition here: distance between the floor drain and the gas cylinder > 2m. In case the cylinder should leak, the gas might possibly "run" into the sewage system, hence the 2m distance. In addition, the utility room is frost-free but ventilated. Each newly connected cylinder is also checked with gas leak spray. We will probably also install gas sensors and connect them to "our" smart home system.

In the kitchen itself, I also practiced having the cylinder for years without problems. Special pressure reducer and regular hose checks. My brother had the cylinder outside for years, directly behind the kitchen (outside) wall in a hatch under the wooden terrace. I can only recommend that as well. The 11kg cylinder lasted me about 2-3 months. Currently, I think it costs around €16.

My ex comes from a country where we always had a gas burner in the covered outdoor kitchen for cooking with a wok. Either the burner sat directly on the cylinder or there were "cheap" wok gas burner stands to which the cylinder was connected by a short hose. They never cooked (and usually did not eat) inside the house itself. It just crossed my mind that I absolutely have to go back there next year to enjoy fresh fish grilled or fried. Our son is a (very good) cook there ;)

We have that too. For the gas stove with wok burner. The bottle is in the pantry.
