The big debate with hot water storage vessels in Summer is "Is it
cheaper to turn on the CH or use an immersion heater?"

It's only a debate by those incapable of looking up the comparable costs
of their gas and electricity per kilowatt.hr. And, of course, doing the
sums given the boiler efficiency and any heat loss in the pipework between
it and the cylinder.

Other thing is it's a good idea to have the boiler in occasional use
throughout the warm times of the year to prevent the pump and valves etc
seizing up.
