Dusseldorf It is the nightmare scenario for millions of households in the coming winter: Because there is no longer enough gas available, the heating fails.

A safety valve that is installed in every domestic gas network could be to blame. The so-called gas shortage protection closes when the pressure is too low – and thus switches off the heating.

Because gas pipes work in a similar way to water pipes: only if the pressure is high enough does everyone get something.

Lack of gas: Securing gas boilers could become a problem in winter

What actually serves as a preventive measure could become a problem for many people this winter. In many cases, only qualified personnel can open the valve again so that the gas flows again – if there is enough. In addition, if safety valves close in entire streets or even districts, the craftsmen will hardly be able to keep up.
