Well done Bosch
Had a slight problem with the boiler yesterday, the fill valve was letting water through (keyless lever type) which resulted in the PRV kicking in. It has a five year warranty so I called the installer and he called Bosch. Within two minutes I had a text saying that an engineer would be here this morning between 9am and midday. She arrived on time and was all done within the hour.
Pretty good going I reckon and worth a thank you.
