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?

And this one goes around working on people's equipment!!! I despair!

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.
