Will do. Might be tomorrow, but thanks for your help so far!

Hypothetically, could having the cold and hot feeds switched round cause this?
We wouldn't notice any difference in the taps, as they get the cold feed before the potential switch. I did trace them, but may go and double check.

It would still usually fire the boiler, just not deliver hot water. If the boiler’s not seeing the demand, then it’s either the diverter valve (this is what I’ve asked you to check on the codes) or the flow sensor not turning (potential crap in system or knackered sensor).

Sorry for the delay, been fitting the bath today.
Having a play, and d36 is reading 0l/min even with the tap on. Would that point to the flow sensor being dirty?
Given I've had to clean out every tap filter today because they were all blocked with crappie suggests it maybe jammed? Or am I way off track?

Yep, seems logical
Plumber coming tomorrow, will report back
Plumbers been, after isolating the cold water feed into the boiler he was getting mains pressure from the hot, so has diagnosed a cross pipe somewhere.
Argh!
Argh!

No worries! Blame sits squarly with my father in law who "helped" me
One question to help me narrow down where the cross feed is occurring.
If all of my hot taps have a lower flow compared with the cold taps (as they have to go through the heat exchanger), does that suggest that the crossover is after the last tap in the system?
Surely if it was before a tap, the hot would have a flow and pressure the same as the rest of the cold taps (and that corresponding cold tap would have low flow).

We did a lot of rerouting of pipes, and even with the only new tap isolated, we have the same issue. Does the above make sense regarding flows from taps, or is it not that simple?
I think the crossover is after the last taps on the hot/cold feeds, so I think that means we will see what we see- all cold taps are getting cold water straight from mains, as they are joined to it before cross over. High flow, high pressure.
All hot taps are getting water going through the boiler backwards, as the cold feed crosses to the hot after the last taps, so lower flow, as its going through the heat exchanger.
This suggests to me the cross over is after the last hot tap (and I know exactly where), or does it not work like that?

Just to let anyone know who is following the saga, found the crossed pipe, it was a simple error, and took 20min to fix.
Still no insight into why I had brown water when I turned the hot water back on, but the pipe crossing may have cleaned the heat exchanger
