Energy Related Products (ERP) Directive

Energy Related Products (ERP)

The ERP (Energy Related Products) Directive, was put in place to help the EU achieve its 20-20-20 target to reduce energy use by 20% and increase the share of renewable energies by 20% by 2020. Boilers and heating systems will be labelled in the same way as white goods like fridges and freezers are, with the aim of improving efficiency.

From 26 September 2015, the ERP has affected all heating and hot water products, with an output equal to or less than 400kW.

The requirement to fit A-class stand-alone pumps in boiler installations, introduced in January 2013, came from the ERP Directive.

The ERP comprises two directives: Ecodesign and Energy Labelling.


Ecodesign sets the minimum energy performance and environment criteria for energy related products. It is likely that existing boiler products will have an A-G classification, while A+, A++ and A+++ will be reserved for renewable products.

As a guide, a high efficiency boiler will generally be in the A band and a heat pump will be in the A+ or A++band. A Stirling engine Micro CHP product – such as the Baxi Ecogen or Remeha Evita – will be in the A+ band.

Energy Labelling

ERP product label – Working in conjunction with Ecodesign, the Labelling Directive requires space and water heaters to be labelled with an efficiency band, ranging from A+++ to G.

An energy label for the installed system is also required, depending on the components used (for example, a boiler, water heating cylinder and room controls maybe fitted).

The labelling system should be a simple concept for consumers because this system is already established for white goods, and more recently, tyres.

Who is responsible for ERP?


To provide the Energy Label for products


To calculate the system efficiency

To provide the Energy Label for the system

To complete a document called a ‘fiche’ to provide the efficiency figure for the heating system

Baxi will support installers with the tools and documents required to complete a fiche.

The ERP Directive will ultimately make it easier for installers and end users to choose the most efficient products, helping to reduce the end-users’ carbon emissions and energy costs.
