Help: Choosing the Best Combi Boiler for a Shower

[macrefurbs]

I'm considering changing our current Conventional/Regular Gas boiler, to a Combi.
The main reason for doing this, is so that I can run a more effiecent shower.
eg: With a better temparture control, combined with a better flow rate.

But in order to get a combi with a good hotwater temprature/flow rate, it seems that you have go for a boiler with a higher heating output, than you may otherwise choose.
So is likely to cause any problem?

Can anyone recomend a suitable boiler?
We just have a conventional 2 bed semi, so we dont need a central heating boiler with a huge output.
Our current regular gas boiler, is a: worcester Greenstar Ri (Ri18) (eg: 18KW)

And the recommended shower flow rate seems to be 12 to 15 litres per min, so approaching 15 litres would be desirable.

Many thanks

30kw boiler should be fine on weather comp

Sorry Shaun, please explain?

30kw boiler is around 12-14lpm depending on temp rise and weather comp controller will handle the small ish load

So how do I know if the 'comp controller will handle the small ish load' ?

Because it will adjust the boiler to the outside temp
