Laying water pipes in the attic experiences

The hardware store with "bach" at the end offers everything for this, but you have to get the deburrer and scissors yourself (under no circumstances cut the pipe). The fittings are easy to work with. I personally prefer another system from the specialist trade, tece. If you have PV, there are additional options you can use. To supply the storage tank with a surplus regulation from the PV yield and additionally switch on a solar-suitable instantaneous water heater as a post-heater at lower yields. It’s a bit more technology and effort but definitely feasible.
