Still bitter at realising you have a crap heating and hot water system?
Only a fool would do what you did.

Christ, I kill filtered this prick and he still manages to get through. I
think he has his cock in his hand while typing. IMO it would take a fool to
install two boilers in anything but the largest of houses. I mentioned the
idea to a college lecturer (plumbing) who I know and he laughed. I've also
mentioned it to a plumber friend and he laughed too. Hey, maybe we're all
fools!
