earlier, as I was re-firing my Econoburn 150 (initial install completed only a few days ago) after a period of dormancy since this morning, something in the system belched forth a pocket of air (yes, I have air eliminators - in fact, several- one at the top of the primary loop and one at the top of each secondary). I could hear it go "bloonk" in the pipes, and then hear the bubbles move around.
no big deal unto itself-
but, then, seconds afterwards, the circulator between the boiler and the primary loop began to emit what I will call a chattering sound- as if the impeller were dragging slightly on the housing/ volute, or as if some little bit of crud were suddenly dragging on the impeller
(for what it is worth, I also have a Caleffi Dirt Cal at the bottom of the primary loop to catch and remove the crud)
the circulator is a Wilo Star 21 FX - sort of a Teutonic Clone of the Grundfos 15-58 3 speed- and I am REALLY impressed at the design and workmanship of these Wilos.
The circulator is still moving water, but still making the noise-
should I (dear pros and more experienced hydronic DIY-ers):
1) ignore it and hope it goes away... (not my inclination)
2) wait until the system is cooler early tomorrow AM and yank the circulator's motor/ impeller assembly to see what I can see of interfering parts or interloping crud, and try to detect and correct what is going on (thankfully, I do have isolation flanges)
3) assume that some damage has occurred to the circulator and replace this one- putting it on the shelf as a short term back-up?
4) do something else that one of you knows of but I do not...
Thanks, all, as always...
