Counting down to the ErPD’s implementation

From 26 September, all new boilers, heat pumps and water heaters must display an energy label to illustrate their energy performance, grading it from A+++ to G. Manufacturers must provide this label for all products with capacities up to and including 70kW.

Manufacturers are also responsible for making the technical fiche document available to customers, plus providing details on energy class in advertisements and technical promotional material. Electronic versions of labels and fiche documentation then need to be made available to dealers and wholesalers, as well as displayed when products are sold online.

For water heating products, an energy label comprehensively lists details including the brand and model, along with its water heating or storage function and efficiency class, as well as rated heat output. Solar and heat pump labels must show the relevant European climate zone, while all products need to confirm their sound power levels indoors – and outdoors, for heat pumps. Finally, there must be an indication where a product has the ability to operate only during off-peak times (between 22:00 and 07:00).

As with space heating, the energy class of a water heating product relates to its seasonal energy efficiency, ranging from A to G. The same classification is used when labelling hot water storage tanks, where the class is based upon standing heat losses.

When a product offers space and water heating capabilities, the label needs to reflect both these elements accordingly; this is referred to as a “combination label”. As low temperature heat pumps cannot be labelled as a “combined space and water heating product”, heat pump combination products only have one scale: “for medium temperature applications”, assigned to heat pumps that can reach 55°C.

When specific combinations of products are supplied to an end customer – such as a heat pump, cylinder and controls – the new regulations stipulate a package label is provided. Again, it will be down to installers to provide this, calculating it using either the official EU Label Generator or a similar calculator, to complete the fiche.

The efficiency and its class must be displayed on the package label and be accompanied by the technical fiche document. The energy class must also be shown in any advertisement relating to the overall package with energy or price information. Any technical promotional material must also include the space and/or water efficiency class.

Heating installers are required to display the labels to their customers, as well as produce the aforementioned “package label” when selling a group of products.

Package labelling will also affect manufacturers of heating controls, as they will need to indicate the product class of their devices so they can be incorporated into any calculations.

This may seem a lot of information to digest, but the forthcoming changes to the Energy-related Products Directive (ErPD) are a positive move for the industry. They will allow installers to select energy-efficient products more easily, plus highlight their benefits to customers. In turn, more efficient products and systems will reduce emissions and fuel bills while improving the quality of installations as a whole.
