added a radiator to central heating system by connecting to main 22mm flow and return, everything works fine in that respect, however the hot water runs hot for a couple of minutes then runs cold, could this be due to me doing something wrong. i was dead chuffed as well, no leaks or nothing, thought it was too good to be true.
