I need to change my existing boiler due to longstanding issues with my current one which no one can solve (heat exchanger related). I have been recommended either an ideal classic HE or a potterton suprima as they have cast iron heat exchangers.
Have Potterton resolved the issues with the Suprima or are the electronics still dodgy?
