There are also other advantages, such
as being able to largely turn the boiler off in summer and thus
(probably) prolonging its life.

There is no evidence that this is the case at all,

I'd be interested in seeing any. The only mentions I have found are
unsubstantiated statements usually made by peddlers of solar
