CEN/TS 17175-1 : Gas-fired overhead radiant strip heaters and multi-burner continuous radiant tube heater systems for non-domestic use - Safety and energy efficiency -Part 1: H2NG and Hydrogen – Expansion of EN 17175

Scope

This document covers radiant strip heaters and multi-burner continuous radiant tube heaters systems that are intended to be connected to gas grids including gas grids for natural gases of the 2nd gas family where up to 20 mol-% H2 is added to natural gas (H2NG-Y20) and where the quality of the distributed gas without adding the hydrogen is not likely to vary to a large extend over the lifetime of the appliance.
This document covers also radiant strip heaters and multi-burner continuous radiant tube heaters systems that are intended to be connected to hydrogen gas grids where the quality of the distributed hydrogen gas (4th gas family at nominal pressure of 20 mbar) is likely expected to stay within a Wobbe range of 42 – 46 MJ/m³.
