EN 12828 : 2012+A1 : Heating systems in buildings - Design for water-based heating systems.

This standard specifies the design criteria for water-based heating systems in buildings with a maximum operating temperature not exceeding 105 °C. For systems operating above 105 °C, safety requirements may necessitate provisions other than those specified in Clause 4.6, while the remaining clauses remain applicable. It does not modify product standards or product installation requirements. This standard covers the design of heat generation, distribution, emission, and control systems. The design of heat generation systems takes into account the thermal requirements of related systems, including domestic hot water, industrial processes, air conditioning, and ventilation, without addressing their design. It excludes requirements concerning installation, commissioning, as well as operating, maintenance, and user instructions for the systems. It also excludes the design of fuel and energy supply systems.
