This has happened today, I turned the central heating on for about 30 minutes but all the radiators around my house won't heat up. The boiler seems to be working perfectly. Whats wrong with it?

Check the thermostat to see if it's calling for heat. If that is all right then I would check the circulator pump. How many zones do you have?Is this a hot water or steam system? is there more than one thermostat? Can give a better answer if these are known

If your pump is circulating the water, check to make sure, then you have an air block and you'll have to "bleed" the radiators, one at a time starting from the first one. Having this type of heat you should now know how to "bleed" a radiator?

You need to bleed air out of the radiators when you switch on your heating every year.
Normally the top of the rad feels cool only, when air is in the system, but if there's really a lot of air, the whole thing can be cold.

if it has worked ok before your radiators probably need bleeding.you will need an air key for this. it looks like 1 of those old fashioned keys that you would wind an old fashioned clock with. at 1 end of your radiator you will find a small brass screw, put the key onto this and turn it anticlock wise until water comes out.turn clockwise to turn off.start with your highest radiator.

feel the pipes leading to and from the furnace for temperature and feel for vibration or hum from pump. might be as simple as bleeding air from system or maybe the pump , thermostat relay or control unit
