    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.

    Legislation affecting solar thermal

    Given that solar thermal is an uncontrolled heat source, does one have to have any specific qualification to flush and refill a thermal system if the system is heating an open-vented (gravity) hot water system?
