Pro’s
Very good hot water performance.
Backed by very good Worcester Bosch guarantee for complete piece of mind.

Con’s
Very expensive for the little extra hot water performance it gives in comparison to 42kw combi. Not as good as having a system boiler and an unvented cylinder. The improved performance of high powered wall hung boilers mean that this boiler is just not worth it, if you really want the best in hot water go for an unvented cylinder. Unless you have no other choice due to replacing a like for like you can do much better for your money.

Opinion
Very good high performance but a little dated now.
