Activities

One of the main responsibilities of ELVHIS is to raise the awareness of the key European standards, directives and regulations as well legislation bodies for the significance of innovative gas-fired radiant heating and to continue to engage their interest. Actual examples of the diverse national and international activities conducted by ELVHIS to promote the positive ecological and economic effects of luminous heaters and overhead radiant tube heaters can be found here:

The aim of this Resolution is to recommend and encourage ELVHIS members to use the new draft standards of CEN TC 180 to prove compliance of products with the current GAD 2009/142/EC or the future GAR (EU) 2016/426 and also compliance with the Ecodesign Regulation Local Space Heaters (EU) 2015/1188 as long as the official EN standards are not yet published and as long as the standards are not harmonized.

The recent documents of CEN TC 180

 

  • Doc N856 (WI 00180096) prEN 416:2017
    Gas-fired overhead radiant tube heaters and radiant tube heater systems for non-domestic use - Safety and energy efficiency (dated 2017-04-11)
  • Doc N857 (WI 00180097) prEN 419:2017
    Gas-fired overhead luminous radiant heaters for non domestic use - Safety and energy efficiency (dated 2017-04-23)
  • Doc N848 (WI 00180098) prEN 17175:2017
    Gas-fired overhead radiant strip heaters and multi-burner continuous radiant tube heater systems for non-domestic use — Safety and energy efficiency (dated 2017-05)

are reflecting the recent "state of the art" of gas-fired infrared heating appliances concerning technology, safety and energy efficiency. In particular – based on a scientific study of the German Metrology Institute PTB (Physikalisch-Technische Bundesanstalt) - the three draft standards incorporate uniformly a detailed description of the significantly improved method to determine the radiant factor (radiant output) of infrared heating appliances giving reliable and better reproducable results compared to the methods in the standards EN 416-2:2006 and EN 419-2:2006.


 


  • Ecodesign Directive and Ecodesign

 

 

The aim of this Directive is to define ecodesign requirements for energy-related products such as heating products or insulating materials.


The Ecodesign Directive being in force since October 2009 establishes the European legal framework for the setting of environmental requirements for energy-related products (ErP). Gas-fired radiant luminous and radiant tube heaters for commercial and industrial use are covered under Commission Regulation (EU) 2015/1188 of 28 April 2015 implementing Directive 2009/125/EC of the European Parliament and of the Council with regard to ecodesign requirements for local space heaters. Regulation (EU) 2015/1188 came in force on 1st of January 2018 in all Member States of the EU.
Actually (August 2018) the European Commission has launched a study to revise Regulation (EU) 2015/1188. ELVHIS as stakeholder represents the product range of commercial radiant heaters in the revision process.

  • European product and installation standardizsation for gas-fired overhead radiant heaters (CEN/TC 180 Decentralized Gas Heaters)

 

CEN is an international association whose objective is to remove trade barriers by means of standardisation. European standards and technical specifications are developed in Technical Committees (TCs).

 

ELVHIS is active in the following working groups (WG) of Technical Committee 180 (CEN/TC 180):
CEN/TC 180 WG 1: Non-domestic gas-fired overhead radiant tube and luminous heaters – Safety and energy efficiency
CEN/TC 180 WG 3: Non-domestic gas-fired overhead radiant strip heaters and continuous radiant tube heater systems – Safety and energy efficiency More...

 


  • Energy performance of buildings directive (EPBD)

 

This Directive requires that Member States set minimum standards for the energy performance of new or refurbished buildings and to introduce energy performance certificates.
The EPBD Directive was introduced to help improve the energy performance of buildings in the European Union, taking into account climatic and local conditions as well as the indoor climate environment and cost-effectiveness.
The revised Energy Performance of Buildings Directive (EU) 2018/844 has been published in the EU Official Journal (L156) and enters into force as of 9 July 2018. EU countries will have to transpose the new elements of the Directive into national law within 20 months. The new Directive has huge potential for efficiency gains in the EU building sector, the largest single energy consumer in Europe. It includes measures that will accelerate the rate of building renovation towards more energy efficient systems and strengthen the energy performance of new buildings, making them smarter.

  • Energy efficiency, thermal comfort and indoor air quality of gas-fired overhead radiant heaters in modern factories and warehouses

 

In a joint research project, the ITG Institute for Building Systems Engineering Dresden/Germany and the University of Applied Sciences Zittau/Görlitz/Germany demonstrated that gas-fired overhead luminous radiant heaters can also generate extremely energy-efficient, comfortable space heating in modern factories and warehouses. Direct thermal radiation proved to be of great energy advantage here, providing high thermal comfort even at the lower air temperatures found in the production hall. This energy advantage increases as the efficiency (radiation factor) of the overhead luminous heaters improves. The heaters also fulfil stringent requirements where indoor air quality is concerned.

  • Method to determine radiant efficiency
    (PTB R&D project to determine radiation efficiency (DVGW R&D project)

 

So far the radiant factor of gas-fired radiant heaters has been determined on the basis of standards DIN EN 416-2 [1] and DIN EN 419-2 [2] with two equally recognized methods (Method A and Method B) under these standards, whereby Method B has become established as the de facto standard due to its ease of use.
In cooperation with the German Metrology Institute PTB (Physikalisch-Technische Bundesanstalt /Berlin/Germany) ELVHIS has realised a scientific study to improve the radiometric method including its calibration to give more reliable and better reproducible results of radiant factors with one unique method. Within the PTB-study an accurate cosine-behaviour responsivity radiometer head for radiant heaters has been developed and validated including its manufacturing specification.
The scientific results of the PTB research project have been incorpoarated in the new draft standards prEN 416, prEN 419 and prEN 17175. More...

 


 

  • European harmonisation of gas properties (gas quality)

 

The supply of natural gas in the Member States of the European Community so far is regulated in national laws and provisions. The representatives of the European manufacturers of gas devices welcome the initiative to harmonise the natural gas supply in Europe and at the same time not only to guarantee a reliable supply to the consumer but also to include new and forward-looking energy sources such as gas from biogenic materials or synthetically produced gases from renewables. An increasingly important role in this respect will be played by global trade with natural gas, for example through the import of liquid natural gas (LNG) from other regions in the world. More...
