Vaillant Ecotec pro 28

and

Potterton Gold 33kw

Thanks in advance.

Vaillant Ecotec pro 28 - 11.5 lpm

Potterton Gold 33kw - 13.5 lpm

all boilers give the same flow rates for a given kw rating its basic physics a given amount of gas will provide the same amount of heat

You can't have a faster flow rate than that provided by the incoming cold water mains. So a larger boiler may not give a faster output, just hotter water.
