hi all im looking at buying a Worcester Combi Boiler but not to sure how to work out what size combi boiler i need, ive got a 4 bed detached and looking at 9 radiators, is it worked out on the size of ya rooms.. i was looking at the WORCS GREENSTAR JUNIOR 24I COND COMBI NG

thanks

 

That will get the job done, but you'd be better off with a 30 as the litre/min on the water on the 24 isn't that great if you like a strong shower. For the sake of the extra 60quid or whatever it is I'd go for the 30.

 

As said.......go for overkill with the 30i

 

Agreed.
