Hi,
I have just been out to a 155 with poor DHW performance from the bath tap.
I can get very hot water from smaller taps and also if I turn the bath tap to a weaker flow. If this was a combi I'd be assuming 2ndary heat ex is full if debris.
I have found suggestion that poor DHW from these boilers can be due to the blend valve. Would this still be the case when I'm getting good DHW at a lesser flow?
The boiler I'm working on is a Range 155 with an orange panel around the controls.
Any advise welcome!
Many thanks,
Harry.
