Ecodesign Directive: from 2015 only new condensing boilers

After very long negotiations , the Ecodesign regulation was approved which introduces a new energy labeling on the minimum efficiency standards for boilers. In particular, an energy classification from A+ to G is envisaged for space heating appliances and from A to G for domestic hot water production appliances. Hence the obligation to install only condensing boilers, heat generators capable of recovering a large part of the latent heat contained in the fumes which, otherwise, would be lost in the chimney as happens in traditional boilers. The recovered heat is transferred to the heating system, allowing an efficiency of 106% to be achieved compared to 92% of the traditional boiler and 84/85% of an old traditional generator. The installation obligation concerns boiler manufacturers who will no longer be able to place non-condensing boilers on the market starting from 26 September 2015 . This means that from this date, anyone who wants to install a boiler in their home will only have to install condensing models. Only a particular type of non-condensing boiler will continue to be produced which is technically called "open chamber" to be installed when it is not possible to replace an old boiler with a condensing boiler due to problems related to the collective flue of some multi-family buildings .

What is energy labelling?

Water and space heating products represent approximately 30% of internal energy consumption in Europe.
Designing eco-friendly products and promoting high-performance technologies to end users in 2020 will determine:

• An annual energy saving equivalent to 56 million tonnes of oil, quantifiable as the savings obtained if the water and environmental heating systems of two nations as large as Italy were deactivated.

Starting from 26 September 2015, ErP regulation and energy labeling will be applied in Europe to water and space heating products (boilers, heat pumps, micro-CHP devices, water heaters, and water storage tanks hot.

How to read energy labels

There are different labels, based on the type and functions of the product (water heating or space heating only or both, and in this case the label must show both classifications).

In addition to the energy class, the label provides other information that could be useful for understanding which product has the lowest environmental impact (for example power and consumption in different climate zones, noise, etc.).

You can increase the energy efficiency of hot water production and space heating by connecting multiple products and accessories in one system. In this case it is necessary to prepare a system label in addition to that relating to the individual product
