water flow rate and combi

[vulcancontinental]

Not much space inside a combination boiler? Look in some of the airing cupboards around. Look inside a system boiler which is what you'd probably end up with if you didn't choose a combi. A system boiler is a combi with a couple of bit removed a bit more room but not much.

Just get an installer who is familiar with whatever system or appliance you choose, he'll know his way around it. A problem of space or access is only a problem like any other problem until you know the answer, it then becomes just another job.

My water pressure is 10l/min and 1.1 bar.. so wondering if this will make any significant difference

Better not to quote that to anyone as is is not likely to be the dynamic flow rate. Just the static pressure ( with no flow ) and the open tap flow rate leaving no pressure in the pipes.

So pretty poor for having a shower from a combi. You might get a shower flow rate of 5-6 li/min. That is about the performance you get from many electric shower units so usable but not very spectacular!

A combi should not use any more gas for hot water generation.

But a severe disadvantage is that if faulty you have no hot water at all.

At least a cylinder would usually have an electric immersion heater which can be used for months until a boiler can be fixed.

This is the combi I'm planning to have installed.. You have to admit the internal designs are very impressive. Everything looks easily accessible and well thought out. They've even put the schraeder valve for the EV on top

Nope.
You work it out.
