From 26th September 2015, heat pump installers have had to provide customers with energy labels and a product fiche for the products and systems they have supplied. However, many questions from installers still remain unanswered. Here, Commercial Director, Heating and Renewables at Daikin UK Nancy Jonsson covers the questions and answers that are leaving heat pump installers uneasy after the introduction of ErP.
Q: What is a product label?
A product label shows the efficiency of the product and other information including manufacturer’s name, product model, internal and external sound levels. This is available from the manufacturer.
Q: What is a product fiche?
The technical information, or data sheet, required by ErP is related to a specific product, and is often referred to as the product fiche. This is available from the manufacturer.
Q: Is there a difference between the heat pump and traditional boiler ratings?
Yes there is, as traditional boilers cannot achieve an efficiency rating of more than 94%, and therefore, the highest product rating a boiler can achieve is ‘A’. Heat pumps however, can achieve ratings as high as A++ as the technology can produce efficiency ratings of over 100%.
Q: Can I mix products from different manufacturers?
Yes, however you will need to manually calculate and create a ‘package label’ which will show the overall efficiency for the combined system. This can be calculated using the fiche data of each product.
Q: What do I need to produce a package label?
A package label is required when a new system consists of a heat pump along with either, additional controls, a solar system or another heat source. You will need to obtain information from the product fiches of all individual products in order to create the package label. For a system containing only Daikin products, the package label can be created from Daikin’s free to access online energy label generator.
Q: Does a heat pump and cylinder need a package label?
A package label is not required for a system consisting of just a heat pump and a cylinder. Instead, two separate product labels are needed, one for the heat pump and one for the hot water cylinder. It may be necessary to create a package label for the heat pump if additional controls are installed.
Q: Once printed, what do I have to do with the labels?
When printed, the labels can either be stuck onto the product, or stored away depending on the end-users preference. As long as the labels have been given to the end-user, the products will be ErP compliant.
Q: Do I need to print labels for heat pumps already installed, or those about to be installed?
Any heat pumps installed before 26th September 2015 or those which have been bought and are pending installation, and listed in the installer inventory before the 26th September 2015, will not be affected by the ErP energy labelling legislation.
Q: How does this link to the Microgeneration Certification Scheme?
A: The MCS heat pump installation standard has been updated to account for the introduction of ErP. The updated standard, MIS 3005 version 4.3, was published on 6th May 2015 but it is not mandatory to use this standard until 26th March 2016. The main change relates to how the SCOP of the system is estimated. Currently this is determined from the Heat Emitter Guide but product specific data will eventually be published on the MCS website for use instead.
