  • winterize boiler

    Going to look at a house that needs to be wintetized. This house has a boiler just wondering if you have to add anti freeze or can the lines and boiler be blown out ?

    i would say you could just blow the lines out as long as there is no pipe traps .
    then drain down the boiler good

      What about the boiler holding some water ?

        The drain on the boiler should be the lowest point in the system. Be sure you disable the boiler so no one can dry fire it.

          So its can be done with no anti freeze?

            Exactly how we do it.

              Well I looked at this today and the system has connectors supplyed by 1/2" soft copper lines with traps all over the place. No power gas meter is gone . Called Burnham today and they suggested 50/50 anti freeze well off the record. Says to run the system for 2 hour but I have no power . Thinking I should disconnect the connectors and air compresser on the other end? Just worried about the traped sections.

                well if i was draining down a boiler i put in there would be purge valves on the returns .then i would drain as much out as i could then hook up a air compressor to the boiler drain then shut off the return valves and open the purge valve after the pressure is up .
                not knowing what this boiler looks like i cant say for sure how to do it

                i would also take the expansion tank off if its a bladder type and drain it

                  if you open as much as you can and drain as much as you can then try to blow out some of the lines thats all you can do
