Hot-water boilers must meet the EUs ecodesign requirements. WHAT DOES THE DIRECTIVE DO? It sets out the energy efficiency* requirements for new hot water heaters or boilers fired by liquid or gaseous fuels. KEY POINTS The directive applies to boilers with an output of no less than 4 kW and no more than 400 kW, specifically:
For any manufacturer of mass produced or multiple duplicate pressure vessels or boilers operating to the requirements of Section VIII, UG- 90(c)(2), Section IV, HG-515.4(b) Section X, RI-160 or Section XII, TS-200.7, the Team Leader is appointed by either ASME or the National Board of Boiler
The standard qual - ifications for welding procedures, made in accordance with the ANSI/ASME Boiler and Pressure Vessel Code and the ANSI/ASME B31 Codes for Pressure Piping to ensure competent workmanship, are the generally accepted standards. The requirements are not compli- cated, but are frequently misunderstood.
