But the radiators aren't the problem. The problem is that in older apartments, the temperature of the whole building is determined by the apartment complex. We don't have a thermostat in our apartment. The heat is turned on on October 15th, and since we didn't need it then, we turned off the radiators. When we did need heat (which happened while I was gone), Robert turned the radiators back on. That's when we discovered that it's much more reliable to have your own thermostat in your own apartment. Here, I'm either cold and wrapped up in a blanket, or hot and throwing blankets off of me!
I do not like being at the mercy of an apartment building!
