What kind of gas is propane

What should you watch out for when installing and operating a gas stove with propane in the house?

Do you want to operate a gas stove or a gas hob with a gas bottle in a family house or a rented apartment? In this article we clarify important questions, such as: What regulations and technical rules exist? Which gas bottles are allowed in the apartment or house and how do you have to store them? Which pressure reducer must be used and what should be taken into account during installation?

Cooking with gas is still very popular. Either there is already a connection to the natural gas network or amateur and professional cooks rely on propane, the so-called liquid gas, as a form of energy in the gas cylinder.

Focus on the nozzle

First of all: This article is exclusively about the operation of gas stoves with propane gas. It is quite possible that some gas stoves and gas hobs are factory-fitted with nozzles for natural gas. However, if you want to operate the stove and hob using one or more propane gas cylinders, you will need special nozzles.

Don't worry: you usually don't have to spend nights browsing the Internet to find the right nozzles at the mail order company in Taiwan. Many manufacturers include suitable nozzles for gas cylinder operation so that the conversion from natural gas to propane is no problem.

Tip: If you already know in advance that you want to operate the stove with the gas bottle, make sure that the manufacturer or dealer has the right nozzles in the scope of delivery.

Small bottles - use and storage

You should also think in advance which gas cylinders you want to use, where they should be and the storage location. In principle, it is up to the operator which propane gas cylinder to use: 5, 8, 11 or 33 kg cylinders are allowed - even if there are restrictions.

If the gas bottle is to be in the house or rented apartment, only the so-called small bottles come into question. These are, for example, all bottles with a filling weight of 5, 8 or 11 kilograms - a maximum of 16 kilograms.

You can have one of these so-called small bottles connected directly and store another in your house or apartment. The two gas bottles - whether full or empty - must not be in the same room and under no circumstances in bedrooms! That means: If a gas cylinder is connected for operation, you can store another one inside the house or apartment.

Large bottles - use and storage

Propane cylinders with a filling weight of, for example, 33 kilograms can theoretically also be used in the building, but this requires a separate cylinder installation room, which in turn must meet certain requirements.

It is more practical that there is no separate room for it and therefore the 33 kg bottles have to be set up outdoors. Operators can also set up multi-cylinder systems there and store several gas cylinders, but this requires protection “against unauthorized access”, according to the wording of the Technical Rules for Liquefied Gas (TRF) - for example a cylinder cabinet made of non-flammable materials.

Pressure reducer gas stove - e.g. 5 or 11 kg bottle

No gas stove or gas hob in the world works without a pressure reducer, also known as a pressure regulator. This regulates the high, temperature-dependent pressure of the gas cylinder to a constant level so that the gas device can work optimally.

According to the regulations from the TRF, pressure reducers that operators want to use in-house must have the following:

  • Overpressure safety device with visual display
  • manometer
  • Thermal shut-off device
GOK offers two sets that make it particularly easy to establish a secure connection between the gas cylinder and the gas stove or gas hob. On the one hand there is the so-called cooker connection set Pro and on the other hand the cooker connection set Basic. We have listed the differences and advantages in a graphic:


Pressure reducer gas stove - 33 kg bottle

As below Large bottles - use and storage mentioned, there are different possibilities. This also depends on which pressure reducer the operator should use. One thing is certain: the pressure reducer definitely needs the OPSO and PRV safety devices.

Otherwise it depends on which type of system the operator chooses:


Installation and operation are fairly simple, especially when operating a gas stove or gas hob in the house with a small bottle. Operators can choose between the Pro or Basic stove connection set and have all the necessary components in accordance with the technical rules for liquid gas.

If you want to operate the stove or hob with a large external bottle, you should contact a specialist company in advance. Getting information from experts, however, generally doesn't do any harm in the case of planned operation with either a small bottle or a large bottle. After all, the gas system must be checked by an expert / specialist before commissioning and every 10 years, and the result must be documented. Pressure reducers and gas hoses must be replaced with new ones every 10 years.
