Central heating works fine, hot water can be normal or luke warm or go cold, no warning as or when
Has been a bit iffy last month or so, being not as warm as it should be when having a shower (but not everytime) but taps downstairs seemed okay, but today very tempremental ... just as the weather gets nice and cold
From what I've read it could be a sticking 3-way valve or just plain faulty 3-way valve, PCB replaced about 8 months ago the last one had the dreaded 3-red lights. New PCB fixed that straight away, and looked much better quality than the old one
Central heating fires up okay everytime but water seems to have a mind of its own, working perfectly normally or running lukewarm/cold
Boiler about 5 years old, did clean out pipe going to pressure vessel when I changed PCB as that was blocked solid with scale causing PRV to blow and dump pressure ... found that after another suggestion before I coughed up for that new PCB last time
Looking at running X400 through system in near future anyway, followed by X100 after flushing as I doubt that was done when fitted after the amount of scale I removed from the pressue vessel supply pipe (pressure vessel was fine and holding air just a badly blocked pipe), along with a few other issues I have sorted not finished by partners ex when he 'renovated' the house and had the central heated fitted
