Here is a formula right out of the RPA's (Siggy's) Precision Hydronics. Hope this helps.

Hope this helps
Buffer Tank Size = (Desired cycle time in min) (Boiler Btu – System Load Btu )
(Temperature Rise) (8.33) (60)

Buffer Tank Size = (10 min cycle) (1,032,500 Btu – 86,007 Btu system load)
(40°Ä) (8.33) (60)

here is one

V= T x ( heat source- load) divided by delta T x 500
Volumne = 15 minutes x 80,000-2000) divided by 180-160.

Or a 59 gallon tank charged to 180 delta T of 20 would give you a 15 minute run time with a 2000 btu/ hr. load.

The HDS software has a great buffer tank sizing module. try a demo at www.hydronicpros.com
