[QUOTE="Rob_the_rich, post: 459964, member: 8419"] It sounds like you have heating and hot water controls the wrong way around. Turning up the cylinder stat should have no effect on the heating. The bathroom radiator getting hot all by itself could be due to one of two things. Some systems are designed with the bathroom rad tee'd off the hot water primaries going to the cylinder, so that if hot water is turned on, the radiator gets hot and warms your towels. The other reason might be gravity flow, the radiator is above the boiler, hot water rises and displaces the water in the radiator, even though the heating circuit is not switched on. [/QUOTE]
