We’ve put together some key frequently asked questions about the ErP Directive that you should know. If you have any further questions about the ErP Directive and the upcoming changes, contact your Area Sales Manager and they will be happy to help.

What is the ErP Directive trying to achieve?

ErP will help to enhance product quality and reduce environmental impact by ensuring only the most efficient products are installed.

Who is responsible for ErP?

ErP is a European wide directive that affects all member states in the same way, at the same time. It is part of the EU's aim to reduce energy consumption by 20% and increase the share of renewable energies by 20% by 2020.

What changed on 26 September 2015?

Tier 1 ErP was implemented for water heaters, boilers, heat pumps and solar thermal products and they need to meet minimum efficiency requirements. This affected water heaters and space heaters with an output less than 400kW (those less than 70kW require a label). Products already “on the market” were able to be installed still, even after the cut off date, but since 26th September 2015 any new products placed into the supply chain by manufacturers are ErP compliant.

What is Energy Labelling?

Energy Labelling is part of the ErP directive, and came into force on 26 September 2015. It requires products up to 70kW output to be labelled according to their energy rating. Certain combinations of products, when installed together, require a package label. A package is formed by the addition of temperature controls (ie. room thermostat) and/or solar thermal.

What changed on 26th September 2017?

Tier 2 of the ErP Directive came into force. The Energy Labelling Directive was updated to introduce an A+ energy efficiency class and the G rating will be removed.

What’s changing on 26th September 2018?

The Ecodesign Directive will be changing to include mandatory limits on NOx emissions for gas, LPG and oil fired water heaters. For gas/LPG fired products the maximum NOx emissions will be 56mg/kWh and for oil-fired products 120mg/kWh.

What do the upcoming changes mean?

Manufacturers will have a clear obligation to inform buyers about the efficiency of their products, which helps contractors and specifiers to better explain product and system efficiencies to an end user and to provide quotes based on efficiency. The new regulations are also pushing manufacturers to deliver more efficient water heating solutions.
