What is the purpose of having a temperature control setting or dial on a boiler to control the temperature of the central heating when the thermostat controls the temperature of the room anyway?
Is the logic that a setting 3 out of 5 (87 degrees) will heat a required room temperature of 23 degrees quicker than a setting of 2 which might heat the water at only 50 degrees and therefore take longer?
If that is the case, what is the optimum strategy for achieving desired room heat at best economy ie like driving at 58mph is most fuel efficient etc.
