In my house I have 9 radiators upstairs and 6 radiators downstairs and all have thermostats on them. When the heating comes on they all come on apart from two (one upstairs and one downstairs). I have bled the rads and they are fine, but they never get hot no matter what setting I put the thermostat on. Does anyone have any ideas?

I have gone round and checked the valves and they are all open

Hi,
There are two possibilities that I can think of (I am not a plumber so I am sure there are more) 1st sludge has formed in the two rads and is stopping hot water going in 2nd if you have thermostats on your rads these do have small pins at the heart of them which raise and lower as you turn the thermostat. Sometimes (especially with no use over the Summer) they stay in the off position. Just remove the thermostat and loosen them with your fingers. Worked for me.
Good luck

Close off all the rads. that work OK.
Fully open the valves on the remainder, you may have to wait a while for them to start getting hot, but when they become warm at the bottom, you should then be able to bleed them properly.
It may be a slow process but when they are hot, top to bottom, open the valves on your other radiators.
Your problem probably stems from the amount of radiators that you have. Had a similar problem with "only" 10 rads.
Edit:
Cliveyboy is right about thermostatic valves.

If you have a single pipe system, the rads at the end of the system are"nt getting the hot water at the front of the system, could try turning pump up faster as well as restricting flow at the rads nearest the boiler.Is the boiler old

Is the flow to the bad radiators reduced. They would still bleed OK. Check there valves. If that does help shut he heat off re bleed the system when the boiler has cooled

Check your pump is working - water doesn't move around (except by gravity) otherwise: make sure the system is balanced - by adjusting lockshield valves to alter rate of flow. The other factor is the configuration of the pipework - are the affected rads remote from the boiler?

The system requires BLEEDING, you have an airlock within the water circulation Try bleeding the system STARTING with the RAD furthest away from the boiler, then the next one,leaving the RAD NEAREST TO THE BOILER UNTIL LAST.

if theyre hot at the bottom cold at the top, then try bleeding them undoing the valve with a rad key usually on the top right or left side ! otherwise if you have dirty coloured water that comes out you might have to power flush the system !

Is the boiler upstairs or downstairs, must be the pump. Have the rads have been given thermostatic valves on them, verify there settings. have you ever acquire a room stat down stairs in a heated portion of the domicile, ought to this be slicing of heating before upstairs rads get possibility to warmth up.

Remove the heads of the thermostatic valves, tap the pin under the head and then refit.

Make sure the valves at both ends are open
