There is one heating control by the steps leading upstairs. The stairs area is heated by a radiator that cannot be turned off by hand. I notice though that there is a place on the radiator to use a key. I presume then that I can turn this radiator off using a key.
I only want to heat up one room. I want to place the heating control in that room. Is it then okay that I just shut of that radiator by the steps with a key? I presume it is, but just checking.
