All ready for Energy Labeling

What is it about?

From 26 September 2015 the European Commission directives regarding eco-design and energy labeling will apply.

These two directives aim to achieve savings in one of the most polluting and energy-intensive sectors: construction

For placing on the European market, the Eco-Design Directive ( ErP known as « Energy Related Products ») imposes a minimum energy efficiency for heating and hot water production devices in domestic premises. The directive applies to:

generators with a capacity of less than 400 kW
water heaters with a capacity of less than 400 kW,
kettles with a capacity of less than 2000 litres

As in the household appliances sector, the energy labeling of products with a capacity of less than 70 kW will give consumers simple, recognizable information that allows comparisons. on the performance and energy consumption of the product you wish to purchase.

The energy label will be included in all boilers, water heaters and kettles placed on the market from 26 September 2015.

Does it affect me too?

YES, it concerns everyone: professionals and end users

The information indicated on the energy label will allow professionals to recommend the right product and individuals to benefit from the information available.

The user will be able to easily compare the performance of the products.

From 26 September 2015 , the label will be present on the following products: boilers, electric water heaters, thermodynamic water heaters, solar water heaters, storage tanks, heat pumps, solar systems and control systems.

Supplier responsibility

The company that supplies the product on the market is required to equip its equipment or systems with the following documentation:

product energy label;
technical product sheet;
system energy label in addition to the product one, both in the case of selling a system that includes the product in question, and if this, in the future, can be sold combined with other additional devices;
technical data sheet of the system with the parts relating to the product or system already filled in.

Responsibilities of retailers

It should first of all be clarified that the reseller can be anyone who sells, rents, offers for rent/sale and displays an appliance and/or system to the public. Therefore, even professionals such as plumbers, installers or designers can fall into this category. Everyone is required to ensure that:

all devices and/or systems are equipped with their respective labels and ensure that they are clearly visible;
all devices and/or systems are always accompanied by the mandatory technical data sheets;
any type of advertising, promotional or technical material in which energy data or price indications are shown contains an indication of the energy efficiency class.

The new ErP regulations


Appliances for space heating and hot water production must be equipped with the new energy label which will report the energy class and main performance data. The energy class must also be cited in the technical, commercial and advertising documentation of the appliances.


The new ErP regulations impose the minimum energy efficiency that space heating and hot water production appliances must achieve to obtain the CE mark and be marketed in Europe. These new limits will exclude obsolete technologies from the market, significantly raising the level of energy efficiency of products.


Depending on the type of appliance, there are different labels. Those with efficiency classes A, A+ and A++ certify the products with the highest performance. Furthermore, two different classifications are envisaged for domestic heating and for the hot water production service, so much so that mixed products must show both classifications. The labels contain, in addition to the energy class, other information, so that the end customer can make his choice in the most informed way possible.


In addition to the product label, a system label is also provided if a series of combined equipment is offered. This label must also be included in the technical and commercial documentation of the system. Whoever proposes such systems will have to calculate the performance using a predefined calculation algorithm and display the label in order to inform the end user in the best possible way.
