Could anyone please give me some help please.
Hot water ok but my radiators are cold [lukewarm in patches sometimes] i've
bled the radiators.
The pump is running [well humming when switched on] but getting very hot.
I'm guessing there is a blockage somewhere, if there is is there something
I can put in the tank to cure this totally or will I need to drain the water
from the radiator system. If that is the case what is the best way of doing
this and then refilling it.
Many thanks for any help
Have you bled the pump - it sounds as tho it might be dry.
Just remove the big screw in the centre of the pump - you should get a small
leakage. If you get some gurling/spitting then its the air coming out. Thru
the hole you can check the pump is running. Put the screw back after and mop up
the small amount
