Have a Powermax 155 boiler, my tenant has called saying she cant fill a bath as water runs hot for a while then cools - not enough for a nice hot bath!
I got the plumber out who said that the tap temp was only 45 degrees, and the inlet to the mixing valve was only 60 degrees. His conclusion is that the cylinder is scaled up and that no repair is possible as it is a sealed unit. I'm not sure how he was able to test the temp going into the mixing valve or if he is guessing.
Looking at your threads I don't think this is true - is it? We had another property with a similar problem and replacing the blender valve worked.
Any suggestions??
