I have measured my cold tap which has a flow rate of 11.8 litres a minute. The Baxi I am looking at comes with 12.2 Maximum DHW flow rate (Delta T @ 35'C rise) or 15 if I go for the bigger boiler.
Is there any advantage in going for the higher capacity boiler as I assume it is not working flat out. Also does a boiler reduce the flow rate so 11.8L input does not necessarily give me 11.8L output if the boiler is at near capacity but an over capacity boiler with reserves might give me 11.8L output for 11.8L input?
Many thanks to the experts here who always provide great answers.
