What’s the normal flow rate for a combi boiler?
That’s all… You have to remember the cold water at around 12c must go thru the hot water heat exchanger then eventually you’ll get the hot coming thru,for that boiler you’ll get a 35c temp rise at a flow rate of 12.3 litres per min…. So 30 secs or a basin full of water is normal and nothing to worry about…
