I have arrived recently in Germany and I want to get a gas oven.

I was wondering if it's possible to buy the oven, the gas tank, and manually connect them on my own, is this possible legally? Or should I use a professional service?

Update 1: The oven in question is the Ooni Koda 16, and I won't attach it to a gas line as I don't have one, I will attach it to a gas cylinder (bottle).

Update 2: The reason I want a gas oven, is that I want to bake Neapolitan pizza at home, that needs ~500C temperature to be able to cook it properly, as far as I know, an electric oven can't reach beyond 300C.


  1. Regulations forbid to use such an oven indoors
  2. Gas stoves and similar stuff depend also on contract terms (renting)
  3. The oven mentioned in my question can be installed manually without any problems, but only outdoors

Big thanks to all the respectful people who helped me with this, I could've injured myself unless I've seen your answers and setup the oven, thank you!

    Not sure what you mean here. Do you want to connect to the gas line inside your apartment? If yes and there is a connector in the kitchen where the ofen will be placed, you may do this yourself. Everything else must be done by an installer. Gasherd anschließen: welche Kosten fallen in der Regel an?

    You will need a regulator , I have no idea if legal here in the us we hooked my father in laws stove top , furnace with 100 lb bottles and regulators, the gas company wanted annual certification of his bridge so it was cheaper to use smaller bottles we could fill.

    You need a license to scratch your ass in Germany. Its called the arschkratzen lizenz. Jul 3, 2020 at 22:03

    @TylerDurden: that's a common misconception. For quite a lot of things you are allowed to scratch your ass yourself. Provided that you bring a certficate (by someone with license) that you did so correctly... :-P Jul 4, 2020 at 12:04

    Why do you actually want a gas oven? You will end up with a lot of hassle, and an oven that is not nearly as good as a modern electric is. Jul 4, 2020 at 15:00

Update: the stove you refer to is an outdoor gas stove. You don't even need to talk to anyone, using thas stove indoors will violate all kinds of regulations and will pose a huge safety hazard to you. There are also better ways of killing yourself than running an outdoor gas stove indoors.

Unfortunately Ooni doesn't give the power of the stove on their web site, but they say that 440 g of propane (1 lb) will last "up to an hour". Propane has a lower heating value of 46 MJ/kg. At 440 g/h that is 20 kW. I.e. you are far above the 11 kW limit for normal private use of gas burners in a flat.

BTW: you don't need high power to reach high temperature in the stove if the stove has decent insulation and/or a volume that is not much larger than the pizza. For indoor settings such insulation is not only required for gas safety reasons but also for fire and burn safety.
To give you an idea, a quick glance found me that a 20 kW gas indoor pizza stove is the size for making 9 30 cm pizzas simultaneously. Or, thinking from the other side, you get electric indoor pizza stoves with 2.5 - 3.5 kW (suitable for 230 V 16 A i.e. standard electric installation) for a single pizza at a time.

  • If the kitchen is equipped with a plug-in gas outlet, you plug in your new stove and proceed as the manual says.

  • If there is no fixed gas installation available, the bottom line is that hardly anyone cares about the hassle (safety plus safety burocracy plus carrying gas bottles into your flat) and people go for electric (e.g. induction) cooking instead: the electric installatin typically has 3 phases with 16 A for the electric stove, so you can get 11 kW electric stove as easily as an 11 kW gas stove (gas installation above 11 kW has additional regulation).


  • If you are not owning the house, you'll have to talk to your landlord. It is quite possible for the renting contract (or the landlord) to forbid gas cooking for general safety reasons. (If you own a flat in a house, you may have to talk to the other owners, but there I'm not sure)

    • Where the building has a fixed gas installation, a rental flat typically comes with a fixed gas stove already installed.
  • Building and fire safety regulations vary by Land (state, province).

    • You may need to obtain the permission by the chimney sweeper, and have them regularly measure emissions.
      Make sure you talk to them beforehand since they may tell you that you need to put ventilation holes into all doors etc.
    • One important limit is 11 kW - below that things are somewhat easier, but you still need to take care of regulations like minimum distances and required room volume.
    • You can also ask the customer service of the local gas provider (Stadtwerke) about regulations. They'll know even if your house is not connected with gas.
  • For fixed gas installation (gas tank, fixed pipes, fixed connection to stove) call a gas fitter/plumber (in Germany, Gas- und Wasserinstallateur or old name Klempner = plumber is one profession).

  • In general, there is also the possibility that you do the installation yourself and then have a plumber do the safety check only. (Similar for electric installation.)
    Of course, it is quite possible that no local plumber will sign the safety certificate if they cannot sufficiently inspect the installation. So make sure you talk to them beforehand.

  • If we're speaking gas bottle and stove, you can connect bottle, reducing valve and stove yourself. Make sure you have the propane nozzle in. (And if you don't know what I'm talking about, have a plumber show you)
    You still need approval by landlord and also the regulations like approval by chimney sweeper, ventilation etc. still apply.

    For the technical part of the rules, the Technische Regeln Flüssiggas are relevant.

    Keep in mind:

    • no underground storage of gas bottles, no storage in sleeping rooms etc.*
    • at most 16 kg of propane or butane in the house (so one 5 kg reserve bottle plus the normal 11 kg bottle)*
    • you can not fill your gas bottle yourself at the gas station, instead you exchange it for a full one.

* without special installation (e.g. force ventilated gas cabinets)

    Thanks a lot for the detailed answer, it really helps, to give more context, I was willing to install an outdoor small gas oven that can use a gas bottle, it's the Ooni Konda 16. I will see my contract and speak with my landlord regarding this. Thank you so much for the answer.

  • @Kareem: Please see my update. Jul 5, 2020 at 15:18
  • Thank you @cbeleites unhappy with SX You are an expert, I am also convinced and now I realize more that it's not worth it, from safety perspective and from "pizza perspective". I gave up on that idea, I don't want to risk injuring myself or others. I will look for other electric solutions, It would be great if you could suggest any ideas on reaching those high temperatures using an electric oven (standard), you are an expert. Once again, Thank you :)

  • @Kareem: I'm not an expert on pizza stoves :-) my gas knowledge comes from being chemist (training on harzadous materials) and from having been a gas stove user. For electric pizza stoves, you'll have to decide between 2 varieties: the ones that look like large waffle irons which can be put on the table, and the "kitchen appliance" ones that are more like a low baking oven. From what I've seen, the "waffle iron" is probably faster and more enery saving when making a single pizza, the "kitchen appliance" ones are probably better for making many pizzas in a row, and they may be more versatile(?)

You must contact the local regulating authority and building management. They treat regulations seriously in Germany.
