Hi there,
I am a complete plumbing novice but hopefully I can give you enough info to help me out.
I live in a 3rd floor flat, I have a combi boiler (a vokera compact 24) and my shower is a mixer system (a previous plumber called it a Bristan).
The shower runs hot then cold constantly, gradually changing from luke warm/cold to scalding every few seconds.
I had a plumber out for a different issue and asked for his advise on the shower, he said that it was either the thermostat within the mixer unit which was faulty or it was because I have "mixed pressures". He advised running the hot tap whilst showering to see if that solved the problem. This hasn't helped.
My question is does it sounds like I need to:
A) buy a new mixer shower? - in which case can I just remove the existing unit from the wall and replace it with a new one or is it more complicated than that?
B) would a new shower not fix the problem? In which case might it be something I can have looked at in the boiler? I read somewhere online about a similar problem being caused by a "fault heat exchanger".
Any help would be much appreciated before I fork out money on a new shower/plumber to find out it has made on difference.
Thank you in advance for your help.
Kind regards,
Heather
