   Pull all the grates and covers and crap off and vacuum it to within an inch of its life. Only thing that gets ours working properly.

   I agree with Nutty Girl, what she explained is the right way of doing it! After doing this, you just enjoy the warmth!

   If it is a radiator it will need bleeding-

   Make sure the heating and pump are off when you bleed, or it can suck air into the system.

   If you have a conventional heating system with header tank it will refill itself. If you have a boiler that requires re-pressurising you will need to top the pressure back up, once you have bled the air from the system.-

   If by the word heater, you mean radiator, then there is air in it, and you have to bleed the air out. On the top od the radiator you will see on one end a plug with a little square in the middle of the plug. You put a key onto this square, and turn it clockwise. You will hear air hissing , and then water dribbling out. When the water dribbles out, you turn the key anticlockwise to close this little square. You can buy these keys at any DIY shop or B&Q.

   Did you hear the world bleeding, when air pass through the it trap in the heater, you most bleed it, or let the air out, to do this you most have a key and a buket of water, put the key in the nobe and the buket near it when the air come out you will hear it, to this tell water come out.
