Oil heating issue

    Can anyone tell me what the problem may be with my heating. I am resigned to calling someone out but I'd like to be able to point them in a specific direction.
    My boiler is starting up and my pump is working but the rads don't heat. I have bled the boiler the rads the pump , reset the pump and the boiler. There is water in the tank and water in the rads and there is no problem with the oil supply.

    The boilers works away grand but as there is no hot water leaving the system it will just cut out when it starts to overheat. My father suggested there could be rust in the pump ? Is this possible? The heating was not used last year so it's been idle for a long time. There was a lot of air in the rads to be honest but none now. I am lost now can any one help? I am trying to keep costs down and trying to find a good plumber. Also I am worried about how much access to the house a plumber would need as I have an adult with a few disabilities and autism and he won't tolerate anyone in the house apart from me his mum. I am desperate , can anyone help?

    Is the circulating pump spinning?
    Could it be broken fins on it?

    Well its a circulation problem, so firstly how sure are you that the pump is working ?? when you bleed the rads was the water clean ???

    Well it's making noise but may not be working. Water was not crystal clear from rads but it was clean enough , not blackish by any means . Thanks for the reply

    When the boiler is cold, remove the screw at the end of the pump housing and check to see if the armature in the pump is rotating.if its not rotating ,turn off power and using a screw driver see if you can rotate armature

    I'd second the pump.
    Hit it with the handle of a big screw driver. Now I don't mean bounce off it.

    Is the pump low down? It's probably jammed with silt after lying idle. A good tap might get it running again.

    If you have silt/rust in the pump and introduce this into the system you will circulate all the crap into every other fitting and valve. Bad idea. I would isolate the pump with the pump valves and remove and clean it first to see if it is rusted up or blocked. If it is, replace it, as they are not expensive whereas having your whole system flushed is. If you turn the boiler on the pump should vibrate and get hot if it is pumping already as the hot water circulates. If it does not vibrate I would remove and service as above.

    If there is silt in the pump you can bet it's in the rest of the system too. I wouldn't suggest the OP isolate the pump, if it has been on the system for any length of time you can bet the pump isolators will leak when interfered with.

    If that avenue is needed i would suggest he calls a plumber in incase new pump valve's are needed.
