The Energy Related Products Directive (ErP) has applied to all domestic and commercial heating and hot water products through Europe since September 2015.

From 26th September 2018 any water heater sold must have an efficiency/NOx output rating of C or above. In line with the new ErP legislation, we have upgraded our product range so they are all ErP compliant before the September deadline. Read more about the new product range, and legislation changes here.
