Having radiator knob replaced

Is there still a hand tap on the heating system and would you like to have it replaced with a radiator knob? Or are the knobs on all radiators in need of replacement? With a hand tap you control when the radiator is on or off. With a thermostat knob (knob with the numbers 1 through 5 on it), the radiator turns off when the room is up to temperature. To replace the radiator knob, you have come to the right place. On our website you can quickly and easily make an appointment with a plumber.

Replacing a radiator knob has many similarities to disconnecting or moving a radiator. 
The boiler is turned off first. The radiator must be completely cooled down before starting to replace the radiator knob.
 Water must be drained from the radiator until it is empty. As water drains out, the pressure in the boiler will drop. The radiator from which the knob is to be replaced must be completely empty. 
When the radiator is empty, the radiator knob can be unscrewed, a bucket is needed because there is always some water coming out of the radiator. 
A plumber makes sure that if he is going to replace a radiator knob, that he has Teflon tape with him. The Teflon tape is wrapped around the threads. Clockwise. This makes the coupling watertight. 
The Teflon tape is then used to put the new radiator knob on the radiator. The plumber will do this expertly, so you don't have to worry about the radiator leaking at the knob. 
The water in the central heating boiler will have to be refilled though, then the radiator will be ready for use again.
