Energy Labeling for Heaters

The Ecodesign Directive provides a framework of the requirements for the environmental compatibility of energy-consuming products. This was defined with the Directive 2009/125/EC of the European Parliament and the Council. In 2013, an extension of the Ecodesign Directive for heaters came into effect after previous enhancements of pumps and air conditioning units. All manufacturers should meet the requirements and verify the energy label by September 2015.

The energy label specifies the heating capacity, efficiency class and sound power level as well as the energy consumption using a color scale from green (efficient) to red (wasteful). The Directive for Energy-related Products – ErP Directive - enables efficiency and emissions comparisons for different types of heaters (or “lots” of heater).

Our experts are available to provide you support and advice in the fulfillment of the legally binding requirements of the Ecodesign Directive and all its amendments. Facilitate market access for your heaters with our test results, measurements and certifications while meeting the relevant requirements of the ErP Directive.

Using the services of TÜV Rheinland for the Ecodesign Directive, you can:

• Ensure compliance of energy-related products with legal requirements
• Actively contribute to environmental and climate protection
• Reinforce trust amongst the general public with a recognized energy label
• Profit from the comprehensive know-how of our experts in the field of ecodesign and heating technology

• Assistance in achieving ErP-ready status
• Issuance of internationally valid certificates and test reports
• Implementation of EC type-examination
• Independent validation of effectiveness and emission limit values
• Initial testing according to the Construction Products Regulation (CPR) and project support
• Navigation through the certification process and certification according to the ErP Directive
• Evaluation of worldwide market access opportunities
• Independent production audits
• Production monitoring within the context of the Pressure Equipment and Gas Appliances Directive and the Construction Products Regulation
• Identification of pin profiles

A summary of certain types of heaters in lots enables the comparability of energy efficiency.

• Lot 1: Boilers and combi heaters
• Lot 2: Water heaters
• Lot 15: Small heaters for solid fuel
• Lot 20: Single room heaters
• Lot 21: Warm air central heating (without CHP for central heating systems)

A distinction is made between individual heaters and complete systems. All individual heaters and systems with a heat output up to of 70 kW must be labeled with an ErP energy efficiency label. Systems must also have a "package label".

With regard to labels for refrigerators, washers or stoves, all heaters and energy-related products will have an energy label starting September 2015. The efficiency class is indicated by means of a scale. From 2015 to 2019, this will range from A ++ to G. Starting 2019, the scale will be moved higher to accommodate more economical heaters. This will range from A +++ to D.

Oil and gas boilers, heating pumps, micro combined heat and power units, as well as storages must adhere to the Directive for Energy Related Products (ErP), also known as Ecodesign Directive, starting September 2015. From this point it will become obligatory to label all heating appliances and water heaters accordingly.

Our laboratories test whether your heating appliances meet the requirements of the Ecodesign Directive and whether they can be granted an energy label. After successful completion of the testing procedures, you will receive a certificate attesting the correctness of your energy label and its compliance with the regulations. This will allow you to place your heating appliances in the market.

Our test stands for heating technologies can test the following products:
