Construction costs are currently skyrocketing

Intermediate meter must be located in a frost-free area? That is not possible for me at all. The water pipes are certainly branched under the plaster, and there is not a separate pipe from the house connection to each withdrawal point. Or does it have to be that way? For me, the connections will soon be made by the municipal utilities, so I do not know exactly.

If it freezes, it can break. In that respect understandable. What you do from the meter to the point of use is your problem. You also do not have a meter for every point of use.

And there they were again, the luxury problems: Complaining that the m3 of water costs 6 euros, but happily watering the lawn with it...

Honestly: if those are the real problems in our country, then we neither have an energy crisis nor inflation.

You are right. You simply should not water the lawn. I do water my fruit trees during very hot and long drought periods (I have already lost some due to the drought, I no longer want to take that risk) and young plants. I never water the lawn. Nevertheless, the submeter makes absolute sense, it saves money.

everything that is accepted by the supplier in terms of fittings / meters (must be accepted) must be frost-free. This applies to electricity and even more so to water. Otherwise, the person from the supplier will come and turn around immediately again ;)

With us, the submeter is located in the basement, just before the water pipe goes outside. That is also where I drain and turn it off in winter.

Does the submeter have to be located in a frost-free area? That’s not possible for me at all. The water pipes are certainly branched under the plaster, and there isn’t a separate pipe for each outlet from the house connection. Or does it have to be like that? My connections will soon be made by the municipal utilities, so I don’t know exactly.

Your main meter is also located in a frost-free area, right?
For us, the submeter was installed right next to the main meter, both in the utility room. All indoor water pipes come off the main meter, from the submeter goes the one to the frost-proof outdoor faucet. I can even use that in winter.
