Warm Air Heaters – ErP 2018 Lot 21 Directive Effective January 2018
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.
- 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:
- From 01.01.2018: Space heating annual efficiency η s at least 72%
- 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
Information for Warm Air Heating Installers
All Warm Air Heating installers are responsible for ensuring compliance with certain parts of the ErP Directive when carrying out an installation or replacement. Installers have to carry out efficiency calculations for the installed system, provide energy labels and complete the ‘fiche’ document.
Flexiheat UK is committed to supporting installers with everything they need to complete the fiche and ensure everything is ErP compliant. We strongly recommend that warm air heating installers become familiar with how ErP works.
