It is the room thermostat that tells the boiler when to switch on and off. If the thermostat is in your sitting room, keep the doors and windows closed in order to conserve heat, and try turning the thermostat down a bit and learn to live with a slightly lower temperature (put warmer clothes on!!).
to put it simply the boiler sends out hot water from the boiler, it flows through the pipes and radiators and returns to the boiler, as it flows through the radiators the water loses its heat to the rooms, the more radiators you have turned on the more heat lost from the water, when it returns to the boiler the thermisters measure the temp of the water and bring the burner on until it is back up to the set temp, therefore the more rads on the more gas you burn.
You must keep the radiator on in the same area where the thermostat is and it must not have a thermostatic valve. If you do set thermostatic valve to lower temperature than thermostat then you can block the system. i.e. thermostat asks for more heat and radiator says ' I do not need heat' then boiler tries to push heat through a closed valve. Not very good.
