I wonder if anyone has any idea what my problem might be. I had my boiler serviced in July and it seems like it has not been quite right since. Cold radiators (at the bottom) on previously perfectly balanced system was the first noticeable symptom. Then our shower (a Mira Excel) which used to deliver hot water (strangely without moving out of the blue but that is a different issue), started to fluctuate between lukewarm and cold - no hot even if I moved the dial to red and bypassed the safety.
Stupidly, I assumed at this point that there was a shower problem (I put the rads down to getting out of balance somehow) so I purchased a cartridge £100 for the shower and fitted it and guess what - no change.
This was when I did what I should have done in the first instance and carried out more investigation.
I noticed that when I turn on the hot water tap on a medium flow the water temperature fluctuates between hot and lukewarm. This is the part I'm not sure about, should the gas burners stay burning when the hot water is running or is it normal for the gas to go out and then come back on again as that is what is happening.
I have, in fact, called out the Engineer who serviced the boiler and he will be here next week but I like to try and understand things if I can myself.
Any help or comments would be appreciated.
