III. Application
The primary application of a buffer tank is to reduce heat pump, chiller, or boiler short cycling. Hydronic buffer tanks are
used in systems operating below the design load condition, which is most of the time, or in systems having several low
BTU cooling or heating loads calling at different times. This can cause the heat pump or the boiler to short cycle, resulting
in reduced operating efciency and shorter equipment life.
The hydronic buffer tanks are built with 4 connections. Two connections can be piped to the heat pump or boiler, and two
connections can be piped to the distribution system. If piped correctly, the tank can serve as both a thermal buffer and a
hydraulic separator. The heat pump or boiler can be hydraulically decoupled from the distribution system. The tanks are all
stainless steel construction with R-12 insulation, and an ABS jacket.
A 3/8” ID thermal well is located mid-tank. Thermistors can be inserted 3” into the well, or the well will accept the Honey-
well L4006A controls.
Buffer tanks are available in 22, 40, 60, 80, and 115 gallon capacities.
Specify 1 ¼”, 1 ½”, or 2” connections.
