Boiler efficiency Directive correctly applied: These requirements result for your CE-compliant product

Directive 92/42/EEC of the European Union therefore regulates the efficiency requirements of new hot water boilers fired with liquid or gaseous fuels to ensure that they meet strict energy efficiency requirements.

2. The EU Energy Efficiency Directive (2012/27/EU) sets binding targets for EU countries to achieve 20% energy efficiency by 2020. As part of this policy, a number of energy efficiency regulations for boilers were published in 2013. They establish minimum standards and an energy labelling system.

3. Under this directive, a number of energy efficiency regulations for boilers were published in 2013. They establish minimum standards and an energy labelling system.

4. Regulation (EU) No. 813/2013, which amended Directive 92/42/EEC lays down the eco design requirements for space heaters and combined heaters which are not operated with biomass and have an output of less than 400 kW.

(EEA / EEA): consisting of the EU countries as well as Norway, Iceland and Liechtenstein) and in Turkey. For CE marking, manufacturers/distributors of hot water boilers must ensure that their products meet the requirements set out in the directive. easyCE can simplify and accelerate the conformity assessment process for you through the years of experience of our experts.

• Standard boilers,
• Low-temperature boilers and
• Gas boiler.

• Hot water boilers that can be fired with various fuels, including solid fuels
• Equipment for instant preparation of hot water
• Boilers designed for firing with fuels whose characteristics differ significantly from those of the liquid and gaseous fuels normally marketed (industrial exhaust gas, biogas, etc.)
• Stoves and appliances intended mainly for heating the rooms in which they are installed and - as a secondary function - for the provision of hot water for central heating and sanitary water heating
• Appliances with a nominal power of less than 6 kW with gravity circulation designed exclusively for the production of stored domestic hot water
• Boilers made to order.

When operating at nominal power Pn, expressed in kW, and an average boiler water temperature of 70°C , the efficiency shall be 87.5 + 1.5 x log(Pn) for low temperature boilers and 91 + log(Pn) for gas condensing boilers.

When operating at 30 % partial load , the efficiency of low temperature boilers at 40°C boiler water temperature at 87.5 + 1.5 x log(Pn) and of gas condensing boilers at 30°C boiler feed water temperature 91 + log(Pn).

• Analysis of the efficiency of a boiler type in accordance with Module B (described in Annex III to the Directive)
• Completion of the declaration of conformity with the approved type in accordance with Module C, D or E (described in Annex IV to the Directive)

The conformity assessment procedures for boilers using gaseous fuels are different from those mentioned above. They are subject to the same procedures as in the Gas Equipment Directive 2009/142/EC, i.e.:

• EC type-examination by a notified body (details are explained in point 1 of Annex II to Directive 2009/142/EC)
• Completion by the manufacturer of one of the three EC type conformity declaration procedures or the EC verification procedure (details are provided in points 2-5 of Annex II to Directive 2009/142/EC)

• the name and address of the manufacturer and/or his representative
• a written declaration that no similar application has been submitted to another body
• any technical documentation to be submitted in accordance with Section 3 of the Directive

The applicant must also provide the notified body with a model representative of the product. The notified body shall be entitled, if necessary, to request further samples for the performance of the tests.

• A general description of the product
• Design and manufacturing drawings and diagrams of components, subassemblies, circuits, etc.
• Descriptions and explanations required to understand the drawings and plans and the operation of the product
• A list of the standards referred to in Article 5, paragraph 2, applied in whole or in part, and a description of the solutions chosen to meet the essential requirements of the Directive, to the extent that the standards referred to in Article 5 have not been applied
• Results of design calculations, tests carried out, etc.
• Inspection reports

They must therefore cover the design, manufacture and functioning of the equipment to the extent necessary for the assessment.

2. Check whether the solutions chosen by the manufacturer are appropriate in cases where paragraph 2 of Section 5 have not been applied

3. Testing whether the standards specified by the manufacturer have actually been applied

4. agreement with the applicant on a place where the tests are carried out

5. issuing an EC type-examination certificate if the design complies with the relevant provisions of this Directive (The certificate shall include the name and address of the manufacturer, the result of the test and the information required to identify the approved type)

6. Provide reasons if type examination certificate was refused

The directive also provides for certain procedures for the appeal against the refusal

The manufacturer shall take all necessary measures to ensure that the manufacturing process corresponds to the conformity of the manufactured equipment with theType-examination certificate described and guaranteed with the performance requirements laid down in the Directive.

The manufacturer or his representative shall keep a copy of the declaration of conformity for at least ten years from the last date of manufacture of the product concerned.
