The German Drinking Water Ordinance in conjunction with REMKO heat pumps
Under certain prerequisites, drinking water systems fall under the German Drinking Water Ordinance. It fol-
lows that regular sampling must take place and be documented at regular intervals. The installation of the
system and the temperatures are also prescribed. The German Technical and Scientific Association for Gas
and Water (DVGW) Code of Practice W 551 comments on this accordingly. The volume of the DHW heater
(storage tank) and the water volume of the DHW pipe system (3L rule) are decisive for whether the DHW
system falls under the DHW Drinking Water Ordinance
