How to do ErP system calculations and complete the fiche

In the first of our series in conjunction with Ideal Boilers about the new ErP Directive, Adam Foy, Domestic Product Manager, explains how to do the ErP system calculations and complete the required fiche.
On 26 September 2015, the EU Energy Related Products (ErP) Directive comes into force. This regulation is for Ecodesign and Energy Labelling of all space and water heaters, and will be mandatory for all 28 countries in the EU. Compliance with the ErP Directive will be a legal requirement for all installers.

The regulation is in two parts: Ecodesign and Energy Labelling. Ecodesign defines minimum levels of efficiency for boilers with an output of up to 400kW. Manufacturers will be responsible for ensuring their products comply with the new regulations and those that do comply will show the CE mark.
The labelling measures (on boilers with an output of up to 70kW) will mean consumers will be able to compare the energy efficiency of various products to help them make decisions about reducing their energy consumption. Manufacturers will be responsible for supplying labels for their products in addition to a standard table of information relating to that product – known as a ‘fiche’.
The new regulations will have a bigger impact on manufacturers than installers – installers will not require new equipment as manufacturers will be responsible for providing compliant products – complete with labels and product fiches.
Product labels and system calculations
It’s important to remember a number of key points with regard to systems and calculations. Installers supplying a complete heating system will be responsible for completing the system calculations, and then creating and providing householders with the system’s Energy Label and fiche. Installers should note that conventional cylinders and radiators are not included – in addition to pumps, which are individually rated.
Whether an installation requires a ‘system’ calculation depends on whether it meets one of two definitions of a package as indicated by the Directive:
1. A space heater plus a temperature control device and/or a solar device, or
2. A water heater and a solar device.
Package labels must be produced when selected components are installed together. However, installers will not need to supply a ‘package’ label if they are only installing a boiler or a boiler plus hot water cylinder because these are not defined as ‘packages’ or ‘systems’ under the Directive.
Calculating system efficiency
Manufacturers will supply the energy efficiency figures for the individual products, meaning that calculating the whole system efficiency will be as simple as adding together the different percentages of the components used in the system to generate an overall figure.
Installers can find all the information required to calculate system efficiency in the product fiches supplied by manufacturers – this information will be available for products manufactured before 26 September on manufacturers’ websites. The total will then translate into ratings familiar to consumers because they currently appear on TVs and other household appliances.
IdealFicheControls will not carry an ErP label but do play an important part in improving the energy efficiency of a system, so they need to be included in the calculation and rating of a package.
Controls are classified into eight groups – each of which is allocated a percentage score. For example, a Logic+ 30kW combi boiler has a seasonal efficiency figure of 93%. If installed with Class 8 controls, an additional 5% can be added to give a total of 98%, which translates into an A+ rated system.
If solar thermal panels and a solar cylinder are added to this simple heating system, the installer will need to add the percentages given in the manufacturers’ product fiches.
Help for installers
Manufacturers and merchants will provide online calculators/tools to assist the installer with these calculations for quotes and completed jobs. Installers will then be required to complete an energy efficiency fiche – this is different to the manufacturers’ product fiches – which will incorporate the energy efficiency details of the system, and leave this
with the householder.
Manufacturers are already including ErP in their training programmes, so installers can have all their questions answered to ensure they are fully compliant with the regulations.
Ideal is developing a dedicated web portal for installers to calculate and generate package labels. Ideal’s Customer Service team is fully trained to give advice on ErP and to provide additional support as required.
Installers must be compliant
Monitoring and surveillance will be the responsibility of the National Measurement Office (NMO), which will be checking products, labels, datasheets, printed matter and websites. Compliance with the regulations will be mandatory, meaning installers must be aware of their responsibilities and be compliant with the regulations from the start.
