This differentiation of temperature ranges is not relevant for the installation mark obligation. The scope of the Drinking Water Directive (EU) does not contain any limitation of the application temperature (EU). ÖNORM B 5014-1 also refers to the Drinking Water Ordinance (Federal Law Gazette II No. 304/2001) in the definition of hot water in section 3.4 and warm water in section 3.15. Note: ÖLMB Chapter B1 defines an indicator parameter of 25 °C for cold water, but refers to hot water in Annex 6, Section 1.4.1. Date: 13.05.2020
