Energy Efficiency

The Energy Related Products (ErP) Directive and Energy Labelling Directive require that from September 2015 all water heaters in scope meet minimum energy performance criteria and have energy labels which provide the energy ration of the product. The classifications range from A++; this being the most efficient and coded in green to a rating of G; this being less efficient and coded in red.

Such ratings provide transparency of efficiency and a comparable benchmark for water heating products, as standardised European Energy Labels are used.

This website contains the energy class for all relevant water heating products. The full energy label and product fiche information for the Powerflow Smart range can be found below
