ErP Regulations

What are they and do they affect me?

The ErP Regulations (Eco Design of Energy related products Directive 2009/125/EC) are a European wide directive designed to;

  • Improve efficiency of energy using products
  • Achieve CO2 emission savings
  • Provide clear performance information to consumers

They provide minimum standards for efficiency, NOx emissions, noise rating and any standing losses.They are split into 39 lots covering many energy using products including vacuum cleaners.

The key lots covering HVAC products are;

  • LOT 1 – Hydronic space heaters
  • LOT 2 – Water Heating
  • LOT 6 – Air Handling Units
  • LOT 10 – Residential ventilation units
  • LOT 11 – Fans, circulating pumps
  • LOT 21 – Fan coils, coolers, heat pumps etc

The requirements for performance information for the consumers are set out in the Energy Labelling Directive (2010/30/EU). This sets out the requirements for product labels, test regimes and provides a common set of energy ratings across technologies for all member states.

A key point to note is that the Energy Labelling Information does not just relate, for example, to the boiler, if the system has a boiler programme, thermostat and a solar hot water system. It is the whole product which has the energy label.

The responsibility for the compliance with the regulations is the manufacturers of the products.
However, where for example boilers are purchased from one manufacturer but an air source heat pump is also provided for the same end user, the overall product details must be merged by a third party i.e. the installer.

How do these regulations impact us?

Manufacturers and distributers supplying products covered by the ErP regulations should be aware of the requirements and provide compliant products. Key issues are;

  • Regulations apply to refurbishment as well as new build
  • Minimum standards are set for heat recovery on all ventilation systems providing air for people. Where it is only for a process this does not apply e.g. kitchen ventilation
  • Those exceed Part L requirements
  • If the system also serves other areas e.g. the canteen adjacent, the regulation applies
  • Internal resistances of air handling plant are limited, again to reduce energy
  • As a consequence of the above, air handling plant sizes have increased. Where this is a refurbishment project, this must be taken into account.
  • Regulations cover all boilers and heat pumps with a rates output less than 400 kW
  • Limits for NOx levels are set for different fuels, e.g. 56mg/kWh for gas and LPG, and 120mg/kWh for oil-based boilers
  • Hot water heaters have minimum standard of efficient dependant on the size
  • The merged product information applies to systems up to 70kW and is therefore aimed at the domestic market.

Enforcement of the regulations lies with the National Measurement and Regulation Office and trading standards.

How can we ensure we are compliant?

  • Ensure the building services engineers specify products which are compliant with the ERP regulations
  • Ensure that all product labels and product information are provided to the end users.

The impacts of these regulations is not well known within the building services industry due to them not being well advertised. Patrick Parsons building services engineers are fully conversant with the requirements and can provide advice on how to achieve compliance.
