DIN Standards Committee Building and Civil Engineering

Overview

This European Standard specifies design criteria for water based heating systems in buildings with a maximum operating temperature of up to 105 °C. This standard covers the design of: heat supply systems, heat distribution systems, heat emission systems, control systems, and takes into account heating requirements of attached systems (for example domestic hot water, process heat, air conditioning, ventilation, etcetera) in the design of a heat supply, but does not cover the design of these systems. EN 12828 does not amend product standards or product installation requirements. For some of the measures laid down in EN 12828, stricter statutory provisions have been laid down in German laws such as the Energieeinsparverordnung (EnEV) (German Energy Saving Ordinance). These measures deal with central control, local control, timing control and thermal insulation. This revision of the previous edition became necessary in order to omit restrictions concerning additional safety requirements for systems larger than 1 MW, amongst others; to revise and clarify requirements concerning safety arrangements; to add an informative annex for safety valves; to revise the guidance for dimensioning diaphragm expansion vessels (sealed systems); to add a specification for the water used; to revise statements concerning the pressure maintaining control device. The committee responsible for this standard is NA 041-01-58 AA "Heizungsanlagen in Gebäuden (SpA CEN/TC 228)" ("Heating systems in buildings (mirror committee for CEN/TC 228)") at DIN.
