Ecodesign Directive (ErP) 2015 How to be ready for new EU legislation What will happen from 26 September 2015? From this date it will no longer be possible to produce traditional forced draft boilers. Instead, it will be possible to continue producing condensing boilers and traditional open chamber boilers equipped with high-efficiency pumps and compliant with the new ErP requirements such as emission, noise and efficiency levels. In particular, the installation of traditional open chamber boilers will only be possible to replace old boilers installed in multi-family buildings which discharge the fumes into branched collective flues (CCR). Products placed on the market before 09/26/2015 that do not comply with the requirements of the new directive, such as traditional forced draft boilers and boilers not equipped with a high efficiency pump, can still be purchased, sold and installed.   ErP and ELD: what do they mean and how are they different? ErP : The EU has issued new obligations for Energy Using Products (ErP). The new directive, known as the Ecodesign directive, prescribes minimum efficiency requirements and emission limits for appliances that produce heating and domestic hot water. The Ecodesign directive is aimed at two categories of products relevant to installers and resellers in the sector: Category 1 Includes space heating appliances: electric, gas, oil, combi boilers, heat pumps and cogenerators up to 400 kW. Category 2 Includes appliances for the production of domestic hot water: electric, gas, diesel, heat pumps for DHW, solar systems up to 400 kW and boilers up to 2000 litres.   ELD: in addition to the ErP directive, the EU has also introduced mandatory energy labeling for the same type of appliances up to 70 kW and boilers up to 500 litres. The energy labeling directive is called ELD and requires that new products and systems for heating and the production of domestic hot water are labeled with an indication of their energy efficiency class. By combining the products and components, for example by adding a temperature control unit, it is possible to increase the energy classification of the system which will be calculated by the installer and indicated on the package label. Let's take a look at the new labels...   When and how will the new rules apply?   On 26 September 2015 the new rules will come into effect. Until then, neither manufacturers, retailers or installers have to comply with the new Ecodesign or labeling provisions. Once the new rules come into effect, manufacturers will only be able to manufacture products that comply with the new Ecodesign requirements, and will be required to supply an energy label with the products     Why push condensing technology right away?   For the energy requalification of individual homes, the 2007 Budget Law was extended until 31 December 2015. The request for a 65% tax deduction concerns, for example, the replacement of a traditional boiler with a condensing boiler.     What will Vaillant support be?   7 year guarantee   The 7-year guarantee on new boilers is another excellent reason to offer Vaillant to your customers. In addition, know that by replacing a Vaillant boiler over 15 years old with a new generation one, the warranty extension will be provided free of charge by the Vaillant Official Technical Assistance Center against a maintenance contract.

Various energy labels have been provided based on the use of the generator used: for heating from A++ to G; for the production of domestic hot water from A to G. A new way to guide the consumer The purpose of energy labels is to allow the consumer to easily identify the level of efficiency of a product and to be able to make a homogeneous comparison between products that use different technologies. For products whose transformation efficiency is influenced by external conditions, such as heat pump products, as has been done for air conditioners, the efficiency figure is reported for the average climatic range. In addition to the product energy labels, the European regulations have also provided for the creation of a system label in the event that a plant is created in which various appliances, components and controls operate. This labelling, thanks to the combinations of the data of the various elements used in the plant, will make it possible to create systems capable of reaching levels of efficiency even higher than those of the individual generators. The European regulation states that the system label must be made available by whoever supplies and/or puts the system into operation (sellers-installers); however, this option is also granted to builders.

The concrete commitment to a sustainable future The acronym ÿErP, acronym of Energy related Products?ÿ (Products connected to the use of energy), identifies Directive 2009/125/EC aimed at reducing the energy consumption of products through eco-compatible design. Starting from 26 September 2015, the date of its effective entry into force in the European Union, it will mark an epochal turning point for heating products and the production of domestic hot water. On that date, other regulations simultaneously issued for the energy labeling of products will also become effective in addition to the corresponding Directive 2010/30/EU. The regulation provides that all products intended for heating and the production of domestic hot water with a lower rated thermal power equal to 70 kW can be placed on the market with an ÿenergy labelÿthat highlights theÿefficiency class*. Different energy efficiency labels have been provided based on the different types of appliances/technologies, but all have the same graduated color scale that identifies the various levels of efficiency at a glance. The purpose of the labels is to give the consumer the possibility of identifying it facilitates the level of efficiency of a product by being able to carry out a homogeneous comparison between products that use different technologies. For products whose transformation efficiency is influenced by external conditions, such as heat pumps, the efficiency data reported for climatic bands. In addition to the product labels, the European regulation has provided for the creation of a "system label" in the case of manufacturing plants with various appliances, components and related controls. This second type of labelling, thanks to the virtuous synergy between the various elements, will make it possible to create systems capable of achieving levels of efficiency even higher than those of the individual appliances. Also starting from the same date, new seasonal efficiency limits will be triggered for products intended for heating and combined. These for products with nominal thermal power equal to less than 400kW, will prevent inefficient products from being placed on the market. Also for DHW tanks there will be an obligation to respect minimum heat loss limits. For primary water tanks, these will be subject to compliance with an energy classification based on heat loss. For sanitary accumulations, up to 500 liters there will be the obligation of labeling, from 500 to 2000 liters they will be bound to respect the energy classification. For heat pumps for heating and for mixed appliances, in addition to the seasonal efficiency limits, there will be specific noise emission limits for power sizes. In order to be placed on the market, gas-fired water heaters with solar heat pumps, in addition to energy labelling, will also have to comply with a series of requirements in terms of efficiency.
