Combi advice

[Mpb-10]

I've been to see a customer today, 5 bed house, 2 bathrooms, he's a conventional system, he wants to put a combi in to get rid of the cylinder which takes up some of his bathroom, he wants to remodel bathroom so do away with airing cupboard. Is there a combi that can cope with that size of house? I've seen a few 42 cdi Worcester, vaillant storage combi, however stick off the wall like a fridge. And the Worcester high flow. Anybody fitted any and can confirm they can cope, or got any advice. He doesn't want a megaflo or cylinder for some reason.

at the end of the day it up to the customer, you can only advise. I think they have no chance with a combi, IMO

Any combi large enough to cope is going to be a monster. Be wary of the rating of combis, a lot will only run to 24Kw on heating despite the high heat input on hot water.

Had a similar customer before christmas, insisted on combi because there's only him and his wife there and they don't use much DHW....he also already had 12 rads and wanted three more, I informed him of the possible problems but he was adamant so I fit the Vaillant 937 and tbh he's happy as a pig in ****. The water flow is excellent the rads are all hot, also put him new TRV's on all but one rad.
