Why is my bathroom radiator on when the heating is off? In some hot water systems, the bathroom radiator or heated towel rail is connected to the hot water circuit. Hi, We've got gas central heating and over the last couple of days during the cold weather, one radiator has continued to stay warm during the day while the heating is off. It's really odd and I'm baffled as to why this and only this radiator in the bathroom remains warm.
At first I. Why are radiators still hot even when the heating is off? One culprit could be a misbehaving diverter valve. The diverter valve plays a pivotal role in your heating system, acting as a traffic cop for hot water.
It decides whether the hot water should head to the radiators or the hot water tank, depending on what's needed at the moment. I have 5 radiators in my house, 4 are turned off to 0 at the valve, however, whenever the heating is on at the thermostat, all 5 radiators go hot, so I am paying to heat a full house when I only want one room heated. The only exception is my bathroom radiator, which stays cold when turned off, and this radiator is fairly new.
