Gas Infrared Heating

  • Low Energy Use
  • Low CO₂- Emission
  • Low Investment Costs
  • Low Running Costs



One of the main responsibilities of ELVHIS is to raise the awareness of the key European standards and legislation bodies for the significance of innovative gas-fired radiant heating and to continue to engage their interest. 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:


  • Directive on ecodesign requirements for energy-using products (Ecodesign Directive)


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


The Ecodesign Directive establishes the European legal framework for the setting of ecodesign requirements for energy-related products. The Directive has been in force since October 2009, when it replaced the initial version introduced in 2005 which was limited to energy-using products (EuPs). It is one of the mechanisms used to implement the EU’s top runner approach, the objective of which is to strengthen market penetration of efficient products in the EU single market. More...


  • European product and installation standardisation for gas-fired overhead radiant heaters (CEN/TC 180)


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 4: Efficiency of air heating and overhead radiant heating systems
CEN/TC 180 WG 1: Non-domestic gas-fired overhead radiant tube and luminous heaters More...

  • Energy performance of buildings directive (EPBD)


This Directive requires the Member States to 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. More...

  • 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 and the University of Applied Sciences Zittau/Görlitz 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.

  • Methods to determine radiation efficiency (DVGW R&D project)


The radiation factor of gas-fired radiant heaters is calculated on the basis of standards DIN EN 416-2 [1] and DIN EN 419-2 [2]. Two equally recognised methods (Method A and Method B) exist under these standards, whereby Method B has become established as the de facto standard due to its ease of use. The wide-ranging experiences made using Method B have brought key issues to light over time, answers to which are the objective of the DVGW research project. Mehr...

  • German Energy Saving Ordinance (EnEV 2014)


The Energy Saving Ordinance specifies standard construction requirements to be fulfilled by property developers in respect of the efficient operating energy needs of their building or construction project.


The amendment to the EnEV 2009 is expected in the near future. The parameters for the next decade are currently being formulated. One of the recommendations for the EnEV 2014 made by the building committee leading the project and the economic committee is that the thermal insulation regulations for the building envelope should not be made stricture if the rooms in the building have a ceiling height of more than 4 metres and are heated by means of decentralised blower or radiant heaters. More...

  • European harmonisation of gas properties (gas quality)


The supply of natural gas in the Member States of the European Community differs from country to country, and 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.
