<<Furnaces ...heat air. Boilers heat water.>>
OK
<<First thought is the circ isn't running.>>
All zones seem to heat well. Hot water seems to get to the end of the
longest loop very quickly and the small zone on the second floor gets heat
without a problem. I don't hear any gurgling in the pipes when the just the
circs are running.
<< You sure you have the right circulator? >>
To be honest I don't know for sure, but my type of system is common in New
England and most everyone has the same size and HP circ as I have on each of
my zones.
<<Does it heat 10 feet from the boiler? >>
No issues with getting heat where needed.
<<Is the new Circ running or is there a valve turned off?>>
All throw valves attached to the unit are in the open position so water is
flowing freely.
The problem is not with the ability of the unit to heat the home, it is just
that when the the water inside is being heated it sound like it is boiling,
but not exactly like a boiling pot. I guess a better description would be
it sounds like a sealed coffee can filled to the top with water and with a
few wood beads in the can being shaken. You don't hear water splattering
sound or whooshing but you can hear a non-metalic tapping going on.
This unit as done this since I purchased the house. Recently I had to do
some work on one of the radiators so I thought when I totally drained the
system it would flush out something, but it still happens even after the
flush and fill.
