Fishface here hasn't a clue, not a clue!!!! You have a pipe stat on the
secondary circulation pipe, so when up to temperature the secondary
circulation pump is switched off and the combi reverts back to CH mode.
All secondary circulation loops must be lagged to retain the heat in the
loop.

So it's constantly cycling regardless of water use and firing up the
combi?
Is this where you get your efficiency figures for boilers from - not?


At least dimm gave it a bit more thought this time. Seems a shame to now
have to add in a non return valve to stop water drawn off from the hot tap
taking a short route via the cold supply and the hot water loop return. Of
course he'll now claim he "meant" to say this all the timeg


At this rate Others might well just despair of your constant knee jerk
responses given
without the benefit of a single brain cell.

IMM. The last M stands for misinformation.


Hear hear!
