Yes
I understand a combi boiler isn't neccessarily always the most appropriate choice, especially for large houses. The house is 4 bedrooms with a family bathroom, en suite and downstairs toilet. It currently has a conventional system (?) with a hot water cylinder, cold water tank and header tank in the loft. Country: A combi will be fine in any size house if there is only one person living there. As the combi only supplies one hot outlet its the number of people which is the limiting factor. Two will interface with each other and ensure only one uses hot water at a time. Pipework maybe 28mm as it is a large house for flow and return of the heating circuits. You would have to work out your heat calcs for the whole house and boiler to decide if 22mm will suffice, generally in modern boilers it should do. 1) Is a combi boiler suitable for a large-ish 4-bed house? (kitchen, utility, 2 bathrooms and downstairs toilet). 2) The boiler is sited at the opposite corner of the house to the ensuite and main bathroom. Report Abuse. Combi boi;lers come in a range of different outputs. So that guy was talking through his hat.They have a combi boiler suitable for a 4 bed house. Visit your plumbers merchant and get some leaflets which will tell you what is the best size for your house. Source(s): Plumber.
