I am asking on behalf of my partners father ..... who is 80 years old
and has just put a down payment on a £5000 system for hot water.
I am not convinced it is a good idea.
He is convinced it will put value on his house when he sells up to
downsize.

My father was of the same opinion and it took some robust words from me
following a thread I started about a year ago here
