Jim. I knew you did it some way. Great looking job and an acceptable way to get around
the home owners reluctance to invest in tighter controls.

Dual boilers, \"equal equal\"

Jim,
great looking job, but I would like to know why you didn't pipe theese equal equal? I've always done it just because of my plumbing background and we've found that when our water heaters are not piped this this way (in a duplex system) that one will run more than the other and work harder and it can rob all of the hot water from one while hardly drawing of the other. Please let me know.
Thanks,
Shawn D.

not sure what you mean by equal-equal..but the piping arrangement is set up as a reverse-return system. which means the first boiler that supplies the water and the second boiler recieves the returnwater jim f.

maybey this will clarify??

reverse return is a self balancing form of piping. It increases the amount of pipe but now all units connected will work equally. Great system for multiple water heaters.

equal,equal.

I'm not talking about the system, i'm talking about the near piping, the actual header, the way you would pipe it is that the boilers would be twined together and a a full size tee would be taken off in the exact center of the two boilers, each measure is cut exactly the same on both the supply and return then the draw off each heater or boiler is exactly the same. On duplex and even on multiple installations, we take great pains to ensure theese are exact and have seen overdrawn water heaters if one measure is off only a little.

Very nice. Love all the 3/4" lines on the wall behind the boilers. I'd be proud to say I did it. Dana

I was wondering

if the load was such that you needed both boilers all the time. Would primary/secondary piping have allowed you to stage the boilers during periods of light load such as early fall and late spring?

a sequencer was included in our original bid. but due to cost savings on the homeowners part they opted not to go with it even though we stressed long term savings. upon this decision we did the near boiler piping on a reverse return system... one boiler maintains temp all year and the other is wired of the dry contacts x-x of the argo circulator board

boilers not circuts

I'm not talking about the zones being unbalanced I'm talking about the two boilers boilers themselves, if both the supply and the return header to the boilers are not taken off exactly in the center of where they sit on the floor, water will flow through one boiler more than the other when they are both running...ex. if the boilers sit 40" (center to center of the supply outlets) the header is twinned together, and a full size tee would be taken off at 20" and that would then become the supply header and the same must be done with the return.
