I've recently moved in to a new house with an indirect oil fired burner. As the rooms have always been at best 'Lukewarm', I increased the temperature on the Burner to 75C. It had originally been set to 60C and I thought this would solve the problem. However, there has not been any considerable increase in room temperatures. The sole benefit of Increasing the burner seemed to be heating the cylinder tank which now has scalding hot water!!
There is no thermostat on the cylinder. Is it safe to assume that the cylinder is 'robbing' the radiators of the heat that is required to heat the rooms. I Don't think there is anything wrong with the radiators themselves are they all warm consistently, but just not enough to throw out the heat required, even with the increase of temperature on the boiler.
Would a thermostat fitted to the hot water cylinder and set to 60C provide extra heat to the radiators?
Any advice greatly appreciated, Regards, John.
