I have a pumped system feeding into the top of my hot water cylinder (as well as to my rads). The return from the cylinder meets the radiator returns at the boiler input.
Having drained the system, refilled and bled the radiators my central heating is now working but I dont seem to have any flow of hot water through my cylinder. I'm wondering if it could have air in it which is stopping it warm up. Can these be bled like a radiator?.
There is an unscrewable section on the valve (tap ??) from cylinder, but when I open it there is no sound of air coming from it.
I've had sludge problems earlier, stopping flow of water to my rads downstairs. Might this have now clogged the return from the cylinder and as such stoped the flow.
The pipe from the pump out to the cylinder input gets cooler as it gets nearer the boiler and the out pipe is cold. I've drained the tank to check if the cold water sat in it may be "sinking" any heat passing through the coil but this has made no difference - the heat still doesnt travel to the out pipe of the cylinder.
My pump has 3 settings and its on the fastest speed at the moment. Should I reduce that or will that not help things. (whats the "normal" speed setting for a pump or how do you work out the best setting.)
I know I've rambled on quite a bit, and asked a lot of questions but I thought the more info I give the better chance there is of someone pointing me in the right direction.
Thanks to the various people that replied to my earlier posts.
