    Hi all, first year in our new home which uses oil. In the summer we used elec only. In the winter we got some oil delivered and used that. The oil has just run out so I switched the immersion heater back on but we now have no heating but we do have hot water? The only thing I can think of is maybe the valve is dead but it seems too much of a coincidence that its packed up at the same time we run out of oil.

    Any suggestions on what you think this could be?

    thanks in advance!

    EDIT: forgot to add that when the oil ran out we had neither hot water or heating (obviously).

    UPDATE: I've just tested both of the motorised valves after watching a youtube video. They both appear to be working correctly. ie. resistance when its off. Both behave the same. I am completely baffled!

    UPDATE 2: even with hot water and heating on, pipes are cold both sides of both valves. The only hot pipes I can find branch off from the top of the immersion tank.

    Have you pressed the reset button on the Burner and primed the Oil if it is a One Pipe System? What Boiler is it? The Immerssion is providing the Hot Water at the moment until you get the Oil Fired Heating working.

    aww running out of oil is the worst thing you can do it can really mess up the normal system. all debris at the bottom of your ur tank might be in the supply and filters uck. its not really a diy fix ..get a good engineer in quick time, tell the truth ..ie not I need a service (seen that many times) and then when its running get him to service it at the same time, new fikters etc and ask him about discount oil suppliers ...he might save you as much as he charges ..bite the bullet .

    So, the immersion heater will only heat the water in the hot tank ..

    Now you need to buy some more oil to get the heating on, and the hot water heated by the boiler ...

    If the oil ran out then boiler will have gone to lockout. Strainer at tank and any inline filters will need to be checked/cleaned, after that the oil pump needs to be bled before the burner will ignite again.

    Fill up oil and get your oil guy to bleed the line. Also get your oil guy to show you how to do it if you feel able.

    Also consider getting a watchman or similar to prevent running out in the future.
