ᐅ Looking for a potable water pipe system

Hello,

we are renovating a house from the 1950s and need to replace the water pipes. We are looking for a good system, preferably made of aluminum composite pipe or PVC.
Could you please tell me if this is a reasonable choice (or what questions to ask to determine if it’s suitable) and also recommend a system?
We are currently considering Uponor, Mepla, Marley DREMA, and JRG Sanipex. Are there any experiences with these?

Many thanks!

If building new, make sure to consider the circulation system.

Yes, we are already looking into that. We're not entirely sure if it's really necessary, since it's mainly about preventing Legionella. The house is quite small, and the pipes are all within a very limited area. Is the choice of pipe dependent on the circulation decision?

I won’t comment on the quality of the pipes. I used copper and some kind of plastic piping. I’m not an expert in that area. I have water bills over 400 euros per year and don’t want to imagine how high they would be without circulation and a cistern.

I don’t quite understand that – circulation doesn’t actually reduce water consumption, does it? Do you mean a cistern that collects rainwater, filters it, and then supplies it to the house for use? Maybe you could briefly explain what you mean and how those things are related?

The cistern is only for rainwater for the garden. You really need quite a bit of water for that.
