Boiler advice - What to get?

[Jono_UK]

I am about to put a complete new central heating system into a property. At present is has none. Here is the spec:

It would need to cope with
a family bathroom
an en-suite
a kitchen
a downstairs loo
a utility room

I would like a combi boiler.

Assuming the water pressure is good, what make/model of boiler would you suggest?

Two showers not compatible with a combi unless one's electric AND your mains is good.

Its not a "spec" which has been listed, its a list of requirements, and that is whats needed.

A combi boiler is unsuitable for all those outlets. Unless you are hoping to do the work yourself, take the advice of a competent plumber who can measure the mains flow rate and advise accordingly.

An unvented cylinder and loft cistern will be more suitable based on the info you have given.

Get electric storage heaters.

potterton promax 33 HE combi boiler would do the job but as the others have said you would need to have a good incoming main pressure ???

Wonderful as a Potterton Engineer will think a promax 33 will be, surely it cannot give the DHW flow rate required by ALL these outlets at the same time ??? I thought it gave about 13.7 li/min ???

To remind you the list comprises ( and I have added the typical DHW usage ):-

a family bathroom Bath taps 20 li/min
an en-suite bath taps 20 li/min
a kitchen sink taps 6 li/min
a downstairs loo basin taps 4 li/min
a utility room WMC 6 li/min
total 56 li/min


Even if we restrict the bath taps to 10 li/min thats still 36 li/min

Those Promax must be even better than the CD they sent me says!!!

Not getting anti-combi m8 you sound like me

Combi's were made for flats, they haven't changed

Not at all John!

A combi is a wonderful solution for a small house or flat with no more than ONE bathroom! High efficiency, hot water in a few seconds, minimal space footprint, hot water all day etc.

They can also be used in a hybrid system, combi water to kitchen or shower and cylinder stored water to bath, wmc etc. Ideal!

its 16l/min and when are you ever going to be running all the taps at once

you could go for a Powermax HE but i would advise the 150 model !!
