Use water out of the hot tap, it then only takes about 10-15 mins to raise to temp, you don't need to raise 27l either, you only need the mash water as the sparge water is heated separately. If you turn on the boiler when you raise the grain basket you save a load of heating time there. Cool only takes 30 mins and as it is counterflow it transfers at it is chilling. That takes it down to 3hrs 45mins plus half an hour to clean up...I really need to work out where I'm wasting the other 15 mins! :lol:
Dont use water from the hot tap. Go and have a look in your header tank and youll see the reason why.
