I rent a place with hydronic bake.
Gas furnace, single pipe loop with radiators
tap off, videotape type circulator pump.
The pump became riotous, and the system was
'short cycling` and not heat effectively.
No air when bleeding the radiators.
Thinking the problem be the circulator, I
drained the system and checked the pump.
It looked fine, so I refilled the system and turned
it pay for on. It now works properly.
Why?????
Answers: Sounds close to your air, or expansion reservoir was hose logged and your drain and refill be just what it needed. Just do it again as needed because sometimes that caring of thing lately happens. If it happen to often next you need to replace the expansion reservoir with a bladder reservoir and that should solve the trouble once and for all.
