Bleed the radiators with the heating OFF.
Find the circulating pump and see if it has a speed control. If yes turn it up temporarily in case you have an airlock.
If you have a conventional heating system have a look in the header tank and make sure it has water in it.
If you have a sealed system check that the pressure gauge is showing at least 1 bar.
