Buffer Tank - How To?

Ron Schroeder · February 2006

Hi Hot Rod,

Cv of 42.2 on the 1 1/4" White-Rodgers valve. Not bad but still equal to over 6 feet of pipe. That might be still too much restriction to go between two closly spaced T,s for primary/secondary but but should be low enough to do the straight thru/bypass to the tank with a couple of flow checks.

Thanks,
Ron

Thanks guys...

for the input. HR, I love that picture! :-)

Sorry I wasn't around yesterday...down in A.C. for a little fun overnight.

I will check out that valve - looks perfect for my application.

My Ergo is probably the bigger reason (in addition to primary/secondary) why my return water is rarely below 140 or so...and never below 120 unless the whole system is just firing up. If it is just starting, it takes at least 20 minutes (more if there's a heat or DHW call) to get everything warm - that's a nice cycle! I suppose that's one of the "downs" about not having constant circ. but I manage my t-stat programs just fine to anticipate...I'll admit I'm a tinkerer.

I still will de-couple the boiler though...and I'll try the zone valve trick. If it works well, I'll use it in the other system, too.

Over 100 gallons in your system, Alex? Now that's some mass (volume)!

Like you said Alex, it's all experimentation...and Hot Rod is a king in that endeavor! :-)

Take Care, PJO

System Volume........

PJO
You are correct --- over 100 gallons.
Actually I have the following:
Boiler 5 gallons
Piping 5 gallons (approx)
ErgoMax 27 gallons
Ford Radiant Buffer / Storage Tank 80 gallons
Radiant Tubing 27 gallons

Total: 144 gallons

Ciao....... Alex
