Method for circulating drinking water in drinking water pipeline system, involves measuring circulating drinking water volume, comparing with stored reference value and activating circulation pump if actual value falls below reference value

摘要

The method involves measuring the drinking water volume circulating in a defined time interval by a flow meter (11a,11b,11c) and comparing with a reference value stored in a regulating element (17). A circulation pump (8a,8b,8c) is activated if the actual value falls below the reference value, by which a circulation of the drinking water is carried out till reaching the reference value. The circulation volume desired for a day corresponds to three complete circulations of the total pipeline system. An independent claim is included for a drinking water pipeline system with a supply line for supplying a consumer station with drinking water and a return pipe.
