To be honest, I rarely turn the temp down any more. Even in the middle of winter it'd be 40 degrees C or so.

I find heat loss through the hose automatically adjust the temp for me,.. the colder the day the more heat is lost before the water gets to the brush!

Oh the Mpemba effect ;D.
But it does say hot water CAN freeze quicker, not does. There are too many different scenarios to be certain either way.
Don`t know how wfp systems are affected though.
Interesting all the same, or I`m very sad. Speaking of which Jeremy Kyle`s on.

Post by: G Griffin on October 06, 2009, 04:38:27 pm: I don`t think that`s due to the hot water freezing though.
