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.

Hi. We have been living with a 155 for 12 years and we love it. 7 or 8 year's ago ours started to 'run out of hot water when running a bath', if the flow was reduced it got hotter. We had the blender valve changed. But no better. We were then advised to have the boiler descaled. It took an engineer a couple of hours with some sort of pump attached removing a lot of crud. After that it was superb. Now we have noticed that it is reverting back to poor hot water flow. Our boiler is 12 years old. The question is can we have it done again? If so can anyone recommend a plumber to do it in Rugby, as we have lost the guys contact details....

Warren,
Yes you can have descaling done as many times as necessary. I can do it for you if it still needs doing!
Mike

Hello Mike.
I'm in south London. Do you cover this area? Can you power flush my power max 155?
