Would a larger combi-boiler improve shower pressure?

All combi boiler operate the same way. The model number 24 cdi, 28cdi etc all stand for the hot water output with the heating output always lower. The 24cdi can run heating as low as 11kw and a 4, 5 bed house can easily run on an 18kw system boiler.thescouselander wrote: »With WB at least the power rating is for hot water only with the heating output being lower. Our 36cdi only outputs 24kw for heating IIRC.
24kw on the heating side is pretty big and the problem still stands, you can oversize boilers and it leads to inefficacy. Bigger isn't better. Getting the water pressure looked before throwing in a 36kw boiler is still the best option.0
