What is ErP?

The Energy related Product (ErP) Directive is designed to reduce carbon emissions across Europe. In the same way as on white goods, TV’s and tyres, since September 2015, ErP also applies to domestic and commercial heating products.

The main objective of ErP is to phase out low efficiency products from the market place. ErP also covers electrical powered products, boilers, water heaters and renewable technologies, but for Warm Air Heating applications, where humans are enjoying thermal comfort, then the warm heaters being installed must achieve a seasonal efficiency of more than 72%, from 1st January 2018.

 Requirements :

  • Efficiency requirements (gas and oil)
  • Limit values for nitrogen oxide emissions:
  • Erp Stage 2 for Warm Air Heaters – From 26th September 2018 maximum 100 mg / kWh (180 mg / kWh oil)
  • Erp Stage 3 for Warm Air Heaters – From 1 January 2021 maximum 70 mg / kWh (150 mg / kWh oil)
  • Information must be provided freely and publicly

The importance of being ErP compliant

Since September 2015 the Energy related Product (ErP) Directive has impacted boilers, water heaters and hot water storage tanks. Flexiheat UK are committed to ensuring that all products are compliant and all heating professionals understand ErP regulations.

ErP ObjectivesThe ErP Directive was designed to reduce harmful non-environmentally friendly emissions from energy consuming products. This is to contribute to the European Union’s 20-20-20 targets on climate change and energy.

Targets for 2020 

There are three main objectives for 2020:

  • A 20% reduction in EU greenhouse gas emissions compared to 1990 levels
  • A 20% improvement in the EU’s energy efficiency
  • Raising the share of EU energy consumption produced from renewable resources to 20%

Implementation in two stages:

  1. From 01.01.2018: Space heating annual efficiency η s at least 72%
  2. From 01.01.2020: Space heating annual utilization rate η s at least 78%

 Space heating annual utilization rate :  Definition

The space heating annual utilization rate is a key figure that should take into account the actual operation of heating systems. It is not the firing efficiency. The commission responsible for the directive has recognized that heating works on average 85% in partial load operation – ie in the transition periods – and only about 15% of the full load operation is required and therefore weights the heating efficiencies. Furthermore, inefficient burners, poor insulation and permanent pilot lights are considered with negative factors. Thus, for the first time, different manufacturers can be objectively compared.

Is a Mandatory if –

Warm Air Heaters are being used to provide thermal comfort for human beings – then the heaters MUST comply under the ErP for Warm Air Heaters – Lot 21 of the regulations

 Applications where the  ErP Directive for Warm Air Heaters 2018 are exempt:

  • Door curtains
  • Frost protection of perishable product
  • Horticultural heating (ie glasshouses)
  • Agricultural heating (ie poultry houses)
  • Process heaters/dryers
