The ErP (Energy related Products) Rating is a new requirement set by the European Union which resulted from many years of negotiation between European Members States and the EU Commission.
It is designed to drive improvements in the efficiency and performance of heating and hot water products. ERP rated products must be manufactured and tested to strict performance standards and energy efficiency information must be made available to aid the selection of product. It will ensure homeowners are aware of the efficiency level of their products which is clearly displayed on the energy label. The ErP rating introduces new efficiency classes from A++ to G.
