Vaillant condensing boiler

With the 20/20/20 strategic plan, Europe has the objective of producing 20% ​​more CO2, using 20% ​​more renewable energy and consuming 20% ​​more primary energy. All this year 2020. To achieve these objectives, the EU has issued the ErP (energy related products) Directive which specifies the minimum eco-design requirements for energy-using equipment, including energy efficiency.

The world of heating will also be affected by this revolutionary change. In fact, from 2015 the energy efficiency of boilers will be based on new performance indices which will take into account the seasonal performance. Among the most significant changes of the new seasonal efficiency measurement methodology are the introduction of different nominal temperatures, operation also at partial loads and in standby mode. The new methodology will allow the performance of a boiler to be evaluated in real conditions, based on the efficiency level calculated over a whole year.


ecoTEC plus the excellence of wall-mounted condensing boilers with minimum consumption, maximum efficiency and versatility

The ecoTEC plus series, the latest generation wall-mounted condensing boiler, conceived to guarantee maximum energy savings and maximum comfort and designed to meet the requirements of European regulations regarding energy efficiency which will come into force in September 2015. Furthermore, all the new products and systems for heating and water production domestic hot water heaters must be labeled with an indication of their energy efficiency class. The ecoTEC plus labeling indicates class A.

ecoTEC plus easily achieves this result because in addition to the typical elements of Vaillant boilers it has new components of total innovation: the combustion management system (ELGA), which, by expertly mixing air and gas, leads to a reduction in gas consumption, new electronics and the very high efficiency to guarantee considerable electricity savings. For example, the electricity consumption of the boiler in stand-by is less than 2Watt (less than half of a radiator in operation).

ecoTEC plus guarantees maximum comfort: the boiler provides immediately available hot water without temperature changes.

Thanks to its small dimensions (70 cm high, 44 cm wide and 35 cm deep), ecoTEC plus can be easily installed on any wall. Today it is possible to install it outside where the climate is mild even in winter. EcoTEC plus also has an anti-gel device which allows it to resist temperatures reaching -5øC.

The new simple and intuitive design, thanks to the display with clear and backlit texts, makes the boiler functional, allowing the user to set it up easily and control it.

ecoTEC plus compatible with all Vaillant components and accessories already on the market.

The new EU legislation

Starting from 26 September 2015 it is no longer possible to produce traditional forced draft boilers. Instead, it will be possible to continue to produce 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 as a replacement for old boilers installed in multi-family buildings that discharge 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 they mean and how they differ

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 for installers and retailers in the sector:

-ÿCategory 1ÿIncludes space heating appliances: electric, gas, oil, combined boilers, heat pumps and cogenerators up to 400 kW.

-ÿCategory 2ÿIncludes appliances for the production of domestic hot water: electric, gas, oil, 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 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 domestic hot water production are labeled with an indication of their energy efficiency class. By combining products and components, for example by adding a temperature control unit, you can increase the energy classification of the system which will be calculated by the installer and indicated on the package label.

7 year guarantee

The 7-year guarantee on new boilers is another excellent reason to offer Vaillant to your customers. Furthermore, know that by replacing a Vaillant boiler more than 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.
