Good Morning
Fairly competent DIY-er here, but I'm having trouble bleeding my four loop baseboard hydronic heating system. Crane Sunnyday 6W 102A boiler in basement, 2300 sqft 2 story house.
I've watched several YT videos and such, and they all have one isolate each loop, open the drain on the desired loop, and flow water from the boiler fill valve until the loop is bled. My house does not have drains on each loop. Here's a schematic of what I have.
I have shutoff valve, and a drain valve on the supply/hot side of my loops, but just a single drain valve on the return side.
I've been dealing with air in the system (sounds like a river in my sunroom when the heat comes on, banging pipe sounds, etc) for several years, and the pros I've had out have improved things (for example, adding the spirovent and that drain valve on the return), but it's still an issue.
I'm asking:
1) Any recs on bleeding this system?
2) I'm contemplating replacing the six gate valves & four drain valves on the supply lines with the Webstone "Purge & Fill" valves. I think this would allow me to bleed these loops more easily. Thoughts?
TIA
