    Thermal store combi boiler, hot water flow rate.

    Can anyone tell me the hot water flow rate on a thermal store combi boiler? As opposed. To a 40kw combi that will deliver nearly 16litres per minute. And any recommendations for a good thermal store boiler thanks.

    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...
