Combi boiler advice for 19 rads ?

[pilot1701]

hello
We have a large 4 bed house with 19 radiators of various sizes and one immersion tank fed shower I am thinking of converting the large airing cupboard ( 4x1 meters ) to a on-suite and I would be looking to move or do away with the tank , I am reading in various places that the combi is not going to do it with that many rads , and am wondering if that is true ? and if so does anyone have other suggestions , the on -suite shower will be electric .
thank you in advance
Bryan

Problem is not the radiators mate. It is the hot water demand. You can remove the old airing cupboard and cylinder and fit an unvented cylinder instead. (Garage or loft maybe?)

Thanks for your reply , plenty of room in the loft , the hot water demand will only be for the main shower , at the moment it is only two of us , but as the oil (perhaps I should have said that in the first post , there is no gas here ) boiler is quite old we need to upgrade that first before moving on to doing the bathroom / on -suite
thank you

You'll be fine with a combi, as harvest fields says, rads aren't the issue, hot water demand is, but a high powered combi will cope with the demand from 1 bathroom and an en-suite.

ok thank you
any combi oil boiler recommendations , make / output etc ?

Worcester, Grant, firebird, but I don't have much experience with oil to be honest with you. Some guys on here will be able to recommend better than I can so just hold on till they reply.

I wouldn’t fit a combi in a 4 bed and most of the lads on here will probably tell you the same mate.

Why? 4 bed has no relevance to the hot water usage.

It does if you extend and add another bathroom. Or end up with 3 kids. You will thank me in the long run. Or try to run a tap and a shower at the same time.

For me it depends only on how many bathrooms and people live in that property
