ErP 2018 – What you need to know about the Ecodesign Directive

21 November 2018

Since 01.01.2018, the ErP Directive also applies to building heating systems such as tube heaters. Systems from SCHWANK achieve excellent values here. Learn more about the requirements of the new Ecodesign Directive below.

ErP – what is it?

ErP stands for Energy-related Products and refers to the EU Ecodesign Directive [Directive 2009/125/EC]. The Federal Government has translated this directive into German law with the Energy-related products Act [EVPG]. Its aim is to save energy and other resources in the production, operation and disposal of energy-related products within the framework of Integrated Product Policy within the European Union [IPP]. The entire life cycle of a product is considered accordingly. In addition, uniform legislation is expected to be created across the EU to prevent trade barriers.

How are the product groups divided?

Energy-relevant products are classified into batches, known as LOTs. When it comes to the abbreviation of the product batches,

  • ENER stands for the General Directorate for Energy
  • ENTR for the General Directorate for Internal Market, Industry, Entrepreneurship
  • SMEs GROWTH [formerly ENTR]
  • EPS for the General Directorate for Environment

What is new since January 2018?

From 01.01.2018, the ErP Directive also applies to building heating systems such as tube or luminous heaters [ENER / LOT 20 individual room heaters] as well as to hot air devices [ENER / LOT 21 hot air central heating systems without CHP]. The specific requirements for these product groups are laid down in Regulation [EU] 2015/1188. Accordingly, the requirements for gas infrared heaters include:

  • The indicator for the annual efficiency of space heating [seasonal efficiency] is at least 74% for tube heaters. For luminous heaters, this value is at least 85%. Products, whose index is below this critical value, may
  • no longer enter the market, starting from 01.01.2018.
  • The NOx emissions for luminous and tube heaters: maximum 200 mg/kWh
  • Meaningful product information

How is the ErP index for energy-saving luminous and tube heater technology determined?

The following factors particularly influence the seasonal energy efficiency of luminous and tube heaters:

  • The thermal efficiency of the devices
  • The radiation factor

Both values are estimated to be 15% in nominal load operation, 85% in partial load operation respectively.

  • Furthermore, so-called correction factors are important as well. They take into account:
  • The ability for modulation of devices F[1]
  • Attention! Devices that vary their tube temperature by switching the burner on and off frequently and thereby increase pollutant emissions are not modulating devices
  • The electric auxiliary energy demand F[4]
  • The use of a permanent pilot flame F[5]

Which benefits does the new index have?

With the introduction of the index, the EU promises a shift in the market towards more energy-efficient products. Even consumers benefit from more transparency and comparison options when making a purchase decision. However, this possibility of comparison for radiation heating devices is not new. For the past 25 years, SCHWANK has been working for the European Association for Infrared Radiant Heating Systems [ELVHIS] for an objective comparability of building heating systems with each other and in comparison to other heating systems. As a leader in technology and innovation, we use state-of-the-art measurement and test systems for the reliable and reproducible determination of the radiation performances of industrial heating systems in accordance with the new EN standards 416-2 and 419-2. With the seasonal energy efficiency, the previous standard has now been extended and an index valid across Europe for the energy efficiency of infrared heating systems is required.

Who determines the index?

The respective manufacturers are responsible for the determination of the index themselves. They are obliged to provide this information to the public free of charge. In Germany, the countries are commissioned with monitoring the market in terms of the eco-design and energy label requirements. They are supported by the BAM [Federal Institution under the authority of the Federal Ministry of Economics and Technology BMWi]. The tasks include activities such as spot checks of products and paper tests.

Conclusion: What does the ErP Directive mean in practice?

“As a quality company, we very much welcome the fact that the seasonal energy efficiency now also provides a European quality seal for infrared hall heating devices and that inefficient devices are successively excluded from the market in this way,” says Prof. Dr.-Ing. Friedhelm Schlößer, Chairman of the figawa Gas Division and President of the European Association for Infrared Radiant Heating Systems [ELVHIS]. The Managing Director of SCHWANK GmbH, who is responsible for the technical areas, is considered to be a proven expert in the field of energy and heat engineering.  Prof. Schlößer: “With several employees, SCHWANK is an extremely active member of a large number of national and international standardisation committees, and as a leader in quality and innovation, constantly strives to provide heating engineers, planners and hall operators with transparent, valid and comparable information as a basis for decision-making.” Schlößer: “Another thing that is equally important for energy-efficient hall heating is the correct design of the heating system for the hall conditions which often vary considerably. But even today, the operation of the heating system has enormous potential for energy saving. It is for this reason that we support our customers with highly qualified engineers and technicians in our large planning department, equipped with modern simulation tools. In addition to the outstanding efficiencies and the very long service life of our infrared emitters, we have simultaneously incorporated our many years of experience and expertise into new, fully digital electronic control and regulation technology. This enables us to optimally accentuate the high efficiency values of the individual devices even in the interplay between the building, heating technology and user behaviour. Ultimately, the total value of the customer and his total savings over the entire life cycle counts for the customer.”

How do energy-saving building heating systems by SCHWANK comply with the new directive?

Building heating systems by SCHWANK present the most efficient solutions in the market with the SUPRA luminous heater system and the new DELTA tube heater system. The SUPRA luminous heater “radiates” with an annual efficiency of 94.8%, a radiation factor of 80.9% and extremely low NOx values between 0 and 8 mg/kWh. The latter has become possible only through a specially designed 3D surface and the mixture formula of self-manufactured ceramics.

The DELTA tube heater system stands out with an outstanding annual efficiency of 98.6%, a radiation factor of 80.3% and NOx values between 50 and 65 mg/kWh. But even all other products of the SCHWANK portfolio meet the new standards with flying colours. Ultimately, energy-saving building heating systems have been the corporate goal of the infrared heating specialist and innovation leader from Cologne since the establishment of the family-run company by Günther Schwank over 85 years ago.

How can you lucratively profit from the efficiency potential of energy-saving building heating systems?

The energy efficiency of an indoor heating system stands or falls with the intelligent operation and regulation of the heating system. That is why SCHWANK brings all its experience and expertise gained over 85 years, especially in the technologically unique control technologies for the building sector. In addition to self-developed automatic gas controllers especially for the infrared radiation sector, it is the new fully digital SCT [Schwank Control Touch], which allows the operation of the heating system to be controlled from individual applications to complex large-scale systems and optimised with regard to overall efficiency. At the same time, the state of the highly efficient SCHWANK infrared heaters as well as the optimisation options related to the overall system are displayed to the user. The SCT can communicate with different bus systems and easily integrate into existing building management systems.
