007 X 2

2 circs

Walked into this job to remove 3 rads for renovation purposes, and found a spare 007 circ on site.
1 on supply and 1 on return. - this is not a primary/secondary set-up.
Anybody else done it this way?
Sorry for the poor angles on the photo's

Only thing I can think of is

they needed two circulators in series to double the pressure. But with a 007 and those pipe sizes, that makes little sense.

Schizophrenia maybe? Good Angel whispering, "Pump Away! Pump Away!". Bad Angel shouting, "To the Tank!"

We all wrestle with inner demons, perhaps this is a solution.

Maybe it was installed by a G.S.H.P. loop contractor...

No, there's an expansion tank there. They wouldn't have done that :-)

Maybe, they read the instructions on the pump and saw that it only had a head factor of 12 feet, and they knew the building was 24 feet tall...

12 X 2 = 24...

I've seen stranger things.

2nd look

Looks to me like a puzzle put together by a patron of a home center.

The bullheaded T's are a dead giveaway.

Maybe whoever did the install read that series pumps would increase not only flow, but head also. I mean that must be better right?

As far as if it is okay, it depends. How is the system working? I am assuming this is a converted gravity system?

Steamhead (in transit)

Right, Cosmo

that's exactly what it is. Bet someone thought those big pipes needed big pumps, but HD only had 007s.....

Principal, if you measure the installed radiation and then go here.....

you'll know how much circulation that system really needs. Bet it's less than you think.

Big flow, low head

If by big pumps you mean more flow, parallel is the way to go.

Goodness, that rhymes.

But if what you need is PRESSURE

Be certain to mount them in schmessure...

OK, so I'm not a Brad White. I can not fight...

But my feet know it and they show it, they're Long Fellows :-)

Happy Holidays, Merry Christmas and Happy Channukah my friends.

Double your pleasure

With Double mint gum , or the Double mint twins or double 007's. Seriously though ask yourself this question does it work?? If yes then why mess with it.
