Got itIts an old photo. I didn't want the system on at that time.

Which taco 007?
their are 4 different types with 4 different head pressures
from 5' to 20'+/-
anti freeze [ glyco] keeps the system from freezing up
Sounds like you misunderstood what I was saying.When the pump is off
and the psi of the system is not high enough to maintain [head] water at the top of the zone
the water will be replaced by thousands of bubbles that turn into one big ass air lock
The air is caused by the pump turning
so YES, PSI does matter in a closed system
Pump is Taco 007. Do i need a larger pump for the loops with more head? Zone 3 is the top floor. That's hard to say at this point. The added head loss would be the results the additional length of piping and fittings. Plus an added amount if it's filled with a 50/50 mix of glycol antifreeze.
Distance from boiler to highest loop is about 17 feet. The reason I asked for this height was to estimate the approx. increase in pipe lengths over the other 2 zones and to make sure it didn't exceed the recommended pressure setting on your system,
It is assumed that if you are calling them 3 zones, together with the fact that you have 3 separate circulators, that you have individual thermostats for each. That would pretty much say that the 3 zones are not interconnected.When 2 zones are off and one is on, does the pump force the water to only flow through its loop or does it circulate around the 3 loops going to the path of least resistance?
I didn't look any further than a 007. There are different capacities?
Please provide the info on the "4 different types with 4 different head pressures".
google is your friend, try using it

I guess I should have asked, is the entire system subject to freezing and filled with a glycol mix?
