Energy-related Products Directive (ErP)

All you need to know about…..ErP (Energy-related Products Directive)

The Energy-related Products Directive (EU Directive 2009/125/EC) was introduced in October 2009 to improve energy efficiency, reduce carbon emissions and help achieve the EU target of 20 per cent energy savings by 2020.

The ErP Directive came into force on 26 September 2015 for all heating and hot water products with heat outputs between 70 and 400kW in a bid to ensure that only the most energy-efficient heating equipment is manufactured, specified and installed in the EU.

Energy and carbon savings

Heating and hot water generation is one of the largest users of energy, accounting for nearly half the energy consumption of a non-domestic building and its related greenhouse gas emissions. The EU predicts that the introduction of minimum energy efficiency standards will bring a reduction in energy usage of around 20 per cent in new buildings, leading to significant environmental savings and energy cost reductions for businesses and organisations. Refurbishment projects will also benefit from reduced bills from ErP-certified heating products.

The ErP consists of two directives: Ecodesign and Energy Labelling.

Ecodesign Directive

EU Ecodesign regulations require manufacturers of energy-related products to meet a minimum energy performance standard (see table below) in a move to encourage less efficient products to be replaced with higher efficiency, new generation heating technology.

Only products meeting the Ecodesign regulations will bear the CE mark. Installers will still be able to use products purchased and installed prior that date, however, manufacturers will only be able to sell compliant products after 26 September 2015. The Ecodesign Directive will apply to both new build developments and refurbishment.

EU Directive 2009/125/ECEnergy-related Products Directive
Boilers with rated heat output ≤70kW Minimum seasonal heating efficiency 86% GCV
Boilers with rated heat output >70kW and ≤400kW Useful heating efficiency at 100% – 86% GCV Useful heating efficiency at 30% – 94% GCV
Boilers with rated heat output > 400kW Only Part L applies


From 26 September 2015, ErP regulations will make it mandatory to install high-efficiency condensing boilers below 400kW even on existing heating and hot water systems using non-condensing boilers.

Energy Labelling Directive

As part of the ErP Directive, boilers and water heating products will require an energy label which will range from A+++ to G, rated according to the efficiency. The aim is to make it more straightforward for contractors and installers to select the most efficient product and help towards reducing building operators’ energy bills and greenhouse gas emissions.

Technical information

Manufacturers will provide additional performance and efficiency data on all products to support the labelling. This will be supplied via a product ‘fiche’ which will be included in the product installation manual and available in product literature and on the company website – not dissimilar to the BIM files that Remeha currently offers on all our boiler models.

Remeha and the ErP

The Remeha Condensing Family exceeds the new requirements of the ErP Directive with our products already offering heating efficiencies of around 98 per cent .

As long ago as 1983, Remeha Commercial (formally Broag) introduced the UK’s first commercial condensing boiler, manufactured and supplied by Remeha, into the British Gas Testing Centre at Watson House. As the pioneers of condensing technology, our tried-and-tested condensing boiler ranges – many of which are now in their eighth generation – offer unparalleled efficiencies with ultra low NOx emissions for minimal environmental impact.

For over 30 years, we have worked closely with specifiers and contractors to deliver the appropriate heating solution to meet environmental, legislative and financial requirements. The Remeha Condensing Family has been refined over the years to offer flexible and speedy installation solutions. These include the modular wall-hung Quinta Pro range which can also be installed in cascade or preassembled on bespoke designed skids, and the compact Gas 310/610 Eco Pro range that is supplied on wheels for easy manoeuvrability and can be disassembled where access is restricted. For buildings with typical existing LTHW systems sized on high flow and return temperatures, our ‘full-time’ condensing Quinta Eco Plus, incorporating passive flue gas heat recovery technology, offers full time condensing environment even at 82/71°C flow and return temperatures, making it the perfect retrofit solution for maximum energy and carbon savings.

Remeha condensing boilers are frequently installed in conjunction with renewable technology equipment such as biomass, CHP and gas absorption heat pumps. For this reason, several of our boiler ranges include a secondary return feature that allows them to achieve optimum efficiencies on bivalent systems.

We welcome the introduction of the ErP Directive which supports our long-term mission to continue to innovate with products that maximise heating efficiencies and create the standard for excellence and reliability.
