ErP: Energy related Products

The new European regulations for heat generators

ErP is the acronym for “ Energy related Products ” (products connected to the use of energy) and is the abbreviation that identifies the European ErP Directive 2009/125/EC, defined by the EEC with the aim of reducing the energy consumption of products through eco-compatible design ("eco-design ”).

The field of action of this European Directive is extremely broad as up to now it has affected products such as light bulbs, air conditioners, washing machines, fans, etc. Following the publication in September 2013 of a series of implementing regulations, starting from 26 September 2015 it will also apply to heating products and domestic hot water production.

From the same date, other regulations will also become effective which will implement the energy labeling of the same product families. The transitional period between the publication of the regulations and their activation throughout the European Community was necessary to allow the full transposition of the contents by companies and market players.

Energy labeling of products for heating and domestic hot water production

The regulations issued provide that all products intended for heating and/or the production of domestic water, with a nominal thermal power lower than or equal to 70 kW, are placed on the market with an energy label that highlights their efficiency class.

Note: the regulation provides for the mandatory presence of the energy label for the release of the product from the factories to the market. All previously released products, for example present in distribution warehouses, can be regularly marketed even if they do not have an energy label. Different energy labels have been provided based on the use of the generator used: for heating from A++ to G; for the production of domestic water from A to G.

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 was done on air conditioners, the efficiency data is reported for the average climate band.

In addition to product energy labels, European regulations also provide for the creation of a system label if a system is created in which various devices, components and controls operate.

This labelling, thanks to the combinations of the data of the different elements used in the system, will allow the creation of systems capable of reaching efficiency levels even higher than those of the individual generators. The European regulation provides that the system label must be made available by those who supply and/or operate the system (sellers-installers); However, this right is also granted to builders.
