The Energy Related Products Directive (ErP)
The Energy Related Products Directive or ErP is a key part of the European Union’s drive to encourage consumers to use more energy efficient products and help reach its target to reduce energy use by 20 per cent and increase the share of renewable energies by 20 per cent by the year 2020.
This is a two-part strategy:
EcoDesign regulations - Firstly, the ErP requires manufacturers to produce energy-using products that meet stringent minimum performance standards.
Energy Labelling regulations - Secondly, that these products are clearly labelled using a standard methodology so that consumers can quickly understand the energy efficiency of the products they purchase and make a comparison.
This market transformation strategy has proved highly successful with consumer goods such as fridges and freezers, and from 26th September 2015 it will affect all heating and hot water products. From this point it will be illegal to manufacture or import into the EU products which do not meet the new criteria.
Take a look at our quick guide to ErP in the video below:
The most important aspect of Ecodesign regulations for heating equipment is the emphasis on seasonal energy efficiency.
Seasonal space heating energy efficiency (SSHEE) is defined in the ErP legislation as: “The ratio between the space heating demand for a designated heating season, supplied by a heater and the annual energy consumption required to meet this demand, expressed in %.”
The move to SSHEE as the main indicator of energy efficiency of a product is significant because until the ErP it was possible for manufacturers to offer an indication of efficiency at a single point in time. This could result in exaggerations of efficiency, and is certainly not a clear guide to how a product performs once it is installed.
The added benefit of requiring products to meet minimum seasonal space heating energy efficiency standards is that it is possible for specifiers and users to clearly compare different technologies such as gas or electric heating. The SSHEE which is reflected on the new product labels makes it easy to see which heating products are truly energy efficient.
Sound levels are also taken into account for heat pumps, where minimum criteria levels must be met. Sound levels for heat pumps are dependent on size and the heat pumps are classified according to power outputs.
Energy Labelling regulations
Alongside the new minimum standards that manufacturers must meet is the energy labelling scheme. This is a very important aspect of the ErP as labels are intended to provide consumers with clear information on product performance, and to allow them to make easy comparisons between different types of product.
For space heaters, such as heat pumps, the energy efficiency labels coming into force in 2015 will run from G (the lowest) to A++, with new classes being added in the future. The ultimate aim of energy labelling is that the lowest scoring products will eventually become obsolete.
The entire Ecodan heat pump range has an energy label of A++
Space heaters must carry an energy label appropriate to their product. For example, in the case of heat pumps, the label must also show noise emissions. Heat pump labels will also show a European temperature map displaying three indicative temperature zones. This is considered important for heat pumps as performance can be affected by climate.
For water heaters, such as cylinders, the energy efficiency labels coming into force in 2015 will run from G (the lowest) to A.
Package Labels – providing a label for the system
Heating systems are often comprised of more than a single product. For example a project might include a cylinder with controls and a heat pump working in combination.
With this in mind, the ErP recognises the importance of providing end users with as much information as possible, so from September 26th it will be necessary to provide a Package Label for certain combinations of products. These Packages are defined in the Energy Labelling regulations.
Methods for calculating the space energy efficiency of packages are provided in the ErP legislation documentation. A tool for calculating the energy efficiency of packages of heaters, water and combination heaters is also available on the EU Label Generator website: http://eepf-energylabelgenerator.eu
While it is the manufacturer’s responsibility to provide the energy label for its own products. It is the installer’s responsibility to calculate the system efficiency and provide an energy label for the package (system).
ErP and the Renewable Heat Incentive
The ErP is a significant piece of legislation that will have an impact on the sale and use of heating systems in the UK. As such, the requirements of the ErP will be embedded into our existing and forthcoming legislation on the energy efficiency of buildings, as well as incentive schemes for renewable technologies.
The Renewable Heat Incentive (RHI) scheme has already begun to embrace the new approach of the ErP. The Microgeneration Certification Scheme (MCS) sets industry standards for products used to produce heat and electricity from renewable sources. MCS certification is required for accreditation under the RHI.
In May 2015, the MCS published a new seasonal coefficient of performance (SCOP) calculator. It also updated its Installation Standard for heat pumps. This was a direct result of the introduction of ErP. The introduction of the SCOP calculator will enable certification bodies to use a standard methodology based on ErP to establish whether a heat pump is ErP compliant. It will also be used to determine the Seasonal Performance Factor (SPF) that will be used for the purposes of RHI.
The updates to the RHI regulations come into force on the 26th September. It is important to note that for the following 6 months installers will be able to install heat pumps which entered the market prior to 26th September 2015 using either the new or the old MCS Installation standard for the RHI. However, this period ends on 25th March 2016. After this, all MCS certified heat pumps must be installed using the latest RHI standards which are in line with the ErP. From 26th March 2016, consumers installing a heat pump who wish to claim RHI will need to ensure their chosen heat pump is ErP compliant.
