I run mine pretty low too, but I've modified it to run full whack for hot water
demand, let me know if you want the circuit (after christmas :-). Mind you,
it also runs full whack for 10mins or so at startup, but maybe that's not
long enough to kill off the slime.

I'm interested in the circuit - I would like mine to do flat out for HW
and then I could experiment with low temps for the rads.

Right, back now & I will post it. Will see if I can make it work with an ascii
art so it is archivable, otherwise I will make a sketch & post is somewhere
binary friendly.
