Just to follow-up; the professional came and told me the boiler is surging due to scale. He flushed the system out and noted several code issues with the system (low evaporator 8 inch rise - wrong pipe materials, drain pipe fittings instead of steam fittings, etc. After flushing, the heat is even and quieter.
Thanks for this forum!
