To ensure the longevity of PREMANT plastic sheathing pipe systems, it is important to make sure the heating water is of

sufficient quality. To prevent magnetite formation (iron(II,III) oxide) and calcification in particular, the requirements of VDI

2035, AGFW FW510 and EN 12953-10 must be met.

Before commissioning, a newly-installed heat distribution network, without a heat exchanger if possible, should be circu-

lated and suspended solids must be removed by means of a suitable filter system. This process should also be repeated

after every expansion of the network or every repair.
