Ken, I drain my copper boiler at the end of each session, that is unless I have a senior moment and forget. Regards IDP "Life should NOT be a journey to the grave with the intention of arriving safely in an attractive and well preserved body, but rather to skid in sideways, Champagne in one hand - strawberries in the other, body thoroughly used up, totally worn out and screaming WOO HOO - What a Ride!"

With copper boilers, should you drain them fully after each running, or at the end of the season? Cheers Ken MODEL ENGINEERING DISCUSSION LIST.
