This is possibly more of a physics question but I believe there are some would be professors on this forum so the question that's been racking my head is what would be the most efficient way to heat a HWC in Y-Plan open-vented system?
1/ heat the HWC at the same time as the radiators, or
2/ heat the HWC on its own i.e. separately.
If the former would turning the boiler thermostat up be necessary? The HWC has a second layer of insulation.
Thanks.
