With a combi which is the most effecient method for heating water ?
Do you set the boiler temperature so the temp at the tap is ideal or set it higher so you have to add cold ?
I'm guessing the 1st way the boiler is working for longer but at a lower temperature.
Probably wouldn't make much difference for a sink but for a bath I'm sure there must be a preferred way
