    Rad stats have arrived now with bottles of inhibitor too so can at least sort that now.

    The 3 port valve has arrived but it is a 3 wire not 5 so is for a w plan. I may go for this as it will give priority to keeping the thermal store topped up and it is a 15kw boiler that struggles when hw and ch are called for at the same time with 12 rads.

    Also planning on fitting pressure regulator to incoming mains and set at 2.1 bar to keep everything balanced, can always increase the pressure if it's too low
