Thermal rating?

unless you have a mansion a 24Kw boiler will be adequate and any boiler will do however the main priority in my opinion is the hot water output the bigger the better also to consider is the length of the guarantee some offer 5 yrs (check the small print though) every plumber will recommend a different maker contradicting each other much the same as if you ask whats a good make of car so i'm afraid its down to you
