My system is 7 yrs old w/a He90 Weil McLain propane boiler. This boiler has two circulator pumps in the boiler housing. Starting this heating season the 1st floor rads gurgling only in the morning when the programmable Tstat call’s for heat. There is a spirovent vent but I’m guessing it’s clogged or not venting. If I manually purge this 1st floor zone it’s good for about two days
Question is if there’s a drip or leak when the system goes cold for the night can it draw air into the water?? Also the spirovent is soldered 1 Inch copper would require to drain boiler and somehow remove old unit. Is there a cleaner I can put into the system to clear the vent? Btw I’ve inspected all the 1st floor pipes no leaks. I’m on well water about 450ppm of stuff in the water but there is a water softener so not hard water and PH is good. Last the piping is pex oxygen barrior 3/4 inch from boiler manifold to bb radiators in basement not exposed to sunlight. Thanks
