Hi folks, its been a while since I've been on here. its good to be back in one way and well, maybe not if my boiler is dying.
Weil-Mclain vintage (20+ yrs) gas boiler for winter heating. Was away, came home, temp inside was 55, bumped the therm to 62, heard the unit in the basement kick in as usual. Went down to the basement a minute or so later and heard a sound I know I don't normally hear from the boiler.
It was a perfectly rhythmic, maybe two or 3 beats per second of a sound that's kind of cross between a whistle/tweeting bird and a cricket. I heard it easily from about 20 ft away. Its coming from inside the boiler, seems like upper back corner. There's, what I presume is, a water pump on the outside of boiler/box. The sound is definitely not from there unless its a ventriloquist.
Now, after a few days of maintaining an indoor temp, when the boiler kicks in the tweeting doesn't seem to be nearly as loud as it was. (I now only hear it when I'm much closer to the boiler)
So, a concern? the fact it seems to "work its way out" over time makes me think of lubrication. But of what? I'm hoping you folks might have some more/better ideas of what's going on. And perhaps avoid an embarassing service call for a boiler tech.
thanks
