    thanks for the info ppl. great place to get edu-ma-cated about my in floor radiant, 6 zone, closed loop, Honeywell controls, slant-fin gas fired boiler system.

    my system has a cleaning cycle, (does this mean it is exchanging old fluid for new?) I do have a water softener installed AND, is it necessary to "flush" once every year?

    One pump had to be replaced and Im not so sure I filled the system correctly. gurgle gurgle, no bleeder valves any were.

    Aqua stat just went and have a mechanic coming tomorrow, just wanted some info so i don't look like a complete more on.
