Mira Excel - temperature problems
This question is regarding
Mira Excel (1990-96) Cartridge - 903.33
Hi, we've had the Excel fed from a combi-boiler for about 7 years. Recently we are finding it hard to get any hot water out of it, it's just about warm. We've been told by a heating engineer that the fault lies with the boiler and want's to fit a pressure reducing valve. This is a new problem, it has been fine for years, after reading this site I get the impression that it may be the cartridge, we live in a very hard water area. What do you suggest the best thing to do is?
