Ground floor radiators cold

Advice please.
Ground floor not heating, I have drained off eveything from lowest radiator, as I did this, ALL rads got warm.
Refilled and bled, but only upstairs working.
Stripped pump thinking impeller may be bust, but all sems O.K.
It is a hot water/hot water & heating system.
All sugestions welcome.

Try bleeding the boiler at the boiler first. There are different setup with boilers. In most cases, there are gates located on the supply line (pipe) and the return line. A gate is a valve that prohibits water from flowing through the pipe. Above the gates, there is usually a tap. A tap is a valve that drains water from the pipe. To bleed the system :

1. Turn off power to unit.

2. Close gate on return line.

3. Open tap on return line. Water will spit out indicating air in system. Leave tap open until water comes out in a steady stream.

4. Close tap, open gate and turn on unit.

You still have to bleed each radiator afterwards. You can also go to this site will give you some insight on how your system works.
