    Gravity and vented thermal store.

    Apologies for the unusual question, as I am an interested DIYer. The question is, why do you need a gravity coil, on a thermal store? Surely, you'd get better flow rate from direct connections to the side, as there would be no friction and you could use 35mm or 42mm copper pipe, to a 2 inch...
