Replacement boiler compatability

[kimikazy]

Hi,
Please can anyone advise me whether I can replace my worcester 24i rsf boiler with a worcester 28si 11 as a kind of straight swap? Many thanks in advance for your help.

A gas safe registered installer will have no problem with this at all.

Some additional work will be required, but gas safe registered installer will have no problems with this. Worth looking at other boiler manufacturers than worcester though, again local GSR will advise what he/she recomends.
