    no heat

    Others will be around to assist you. Can you post further details about your system? What kind of boiler,age,service history,etc.?Can you post pictures?

    so many things it can be

    did you replace the circ for a reason? It could be air bound, bad zone valve, thermostat, wiring, valve that is closed, or a broken gate valve, and so on. More in and pics needed

    transformer?

    You mentioned you replaced the transformer? why? transformers rarely go bad unless something causes them to go bad, like a short or bad relay coil. If everything is dead, like it sounds like, could be the transformer again because you never found out why it had to be replaced the first time.

    Its running

    I guess you mean you hear something.So I'll guess thats the circ. you hear. Or is the boiler hot and the house is cold? Do you have a pilot thats lit all the time or does the pilot cycle with each call for heat. A little more info is needed.
