    Has anyone tried using one? I have a loading valve with pump etc in the primary side, the pump triggers when flue temp exceeds 120 deg c which is fine when the thing is running hard but not so good when its on tickover.
    Idea was to have thermostats on flow and return (before the loading valve) set so both pipes have to be warmer than 50 deg c to make a circuit.
    That circuit then goes to differential stat- 1 probe on flow from woodburner, the other on bottom tap on thermal store. If store is more than 5 deg below woodburner flow, fire up pump until one or other condition becomes false.
    The whole setup in parallel with the stat on the flue.
    Any thoughts?
