Intalled a 70 gallon Vaughn indirect water heater. Having problems with it getting airbound every three to four days.
I have installed many of these throughout the years and have never had this problem

Is it pumping away? What model? Any means of automatic air elimination?0 -

that is strange
Usually a set up like that never gets air bound. Air rises to the highest point as I'm sure you know. If it was an Amtrol, I could see it happening, coil under, but over on top? Are you getting air out when you purge it? Could it be a sticking flowcheck?0 -
IFC circ ?
We've had multiple problems with air getting trapped between the check and impeller of IFC pumps . No flow . Happens with circs and flowchecks too close to the top of the circ also . Pumping away with a Spirovent . The Taco instructions state to have a minimum of 12 inches from circ to flowcheck . I'm guessing to minimize that issue among others .0 -
didn't think of that Ron
I never liked the IFC pumps and always will. They save an installer nothing when you gotta go back due to problems. I like either zone valves or flow checks, zone valves being top of the list. How is everything going for you this winter Ron?0
