The Energy related Products (ErP) directive

The EcoDesign of Energy related Products Directive (ErP) is a European wide framework put in place to help the EU achieve its 20-20-20 target to lower carbon emissions by 20%, increase energy efficiency by 20% and increase the share of renewable energies by 20% by 2020.
ErP will eventually encompass all products that have an impact on energy use, meaning all boilers and heating systems will be labelled in the same way that white goods, like refrigerators and freezers, already are with the aim of improving efficiency.
There are two directives within ErP: EcoDesign and Energy Labelling.


Effective from 26 September 2015, Lots 1 & 2 of the EcoDesign directive set minimum efficiency and performance targets together with maximum NOx emission ratings for manufacturers of heating and hot water products. The scope of EcoDesign includes space heating products up to 400kW rated output and hot water heaters up to 2000 litres storage capacity or 400kW rated output.
Most technology types are included such as:

• Gas, oil, LPG and electric heating boilers, including heat only, system and combi variants
• Heat pumps
• Combined heat and power (CHP) (up to 50kW electrical output)
• Gas, oil, LPG and electric water heaters
• Hot water storage cylinders
• Solar thermal hot water

Energy Labelling

Working in conjunction with Ecodesign, Energy Labelling requires space and water heaters to be labelled with an efficiency class, ranging from A++ to G. The product label will be supplied by the appliance manufacturer.
Where certain products are installed together, a package label is also required, depending on the components used (for example, a boiler with a room thermostat).  The installer will typically be responsible for completing the package label, Potterton have a calculation tool available to assist.
The labelling system should be a simple concept for consumers because this system is already established for white goods, and more recently, tyres.
