Step-by-step plan for replacing the thermostat knob

Replacing a thermostat knob is not very difficult, but if you don't know how to do that, the step-by-step plan below will certainly come in handy!

Step 1: Drain Radiator

First turn your radiator down, wait until it is no warmer than 40 degrees and then remove the plug from the socket. Did you do this? Then it is time to drain your heating system via the drain tap.
