Boiler sizing

[Hobo128]

Can anyone recommend me a boiler sizing app. Got a huge house with loads of rads 4 bathroom, ufh and a 250 litre hot water cylinder. Can't find any decent apps to make it easy to size up

dont whole house size it either by mears calculator or mr combi heat loss calc

will take time but room by room

and cylinder sounds a bit small

and make sure mains are up to it if you have 4 folk in showers at the same time, just done this recently and ended up with a small booster set
