I want a high flow system so I can have a decent shower

For an "ordinary" shower then this boiler would be more than adequate.

One potential problem for me is the apparent low flow rate into the
house from the mains

I did a check at the nearest cold tap to the water inlet, ( the cold
water is at mains pressure) - I filled a 2 litre jug and timed it

it came out at about 15l/min

would that change the optimum choice of boiler?

thanks
