    Thermostat Calls for Heat,Circulators Running,No Heat...Hydronic


    Newly installed gas fired Weil-McLain boilers with two zones. On two occassions,thermostsats have been demanding heat ,circulators are running but gas fired boiler does not ignite.

    Each time,I have flipped power switch on and off and that's what gets the system to operate properly?


    Is it possible that relays are sticking...any thoughts?

    There are many possible causes for this. Much more information would be needed to diagnose the problem. Is the system electronic ignition? What is happening upon the call for heat? It would need to be checked when the problem happens to see what point in the prosess the problem occurs. Mabye with more information we could direct you what to check.

    No Heat

    Sounds like a possible lock out problem. You should call your installing contractor to take a look at the problem. If the boiler is relatively new, you may get parts under warranty.

    no,gas fired system has a pilot. All systems seem to be operating,circulators are running but the gas units do not light. The two zone system has a Taco SR502 control,when I flip the power switch to the Taco controls on and off,that's what fires the gas boile and all is well after that

    I took a look

    The Taco SR502 control may have a voltage problem, depending on how it's wired. You could actually jump out the t-stats with care ( not recommended) to see if it's a particular stat or a problem with one on the switching relay's. Let us know what was the problem. Good luck.
