Despite my heating being on a timer it is staying on, the radiators are almost too hot to touch and even if I turn the thermostat down to zero they stay the same, its snowing outside and like the Bahamas in my house, it was too hot to sleep and its becoming unbearable, any suggestions?

Hi divisionepdl and welcome, There's good help here but you'll need to give more information. Type, model and age of heater. Let us know. Good luck.
