Heat-Flo Hydronic Buffer Tanks

Heat-Flo offers a hydronic buffer tank designed to reduce 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, chiller, or boiler to short cycle, resulting in reduced operating efficiency and shorter equipment life.

The Hydronic Buffer tanks are built with 4 connections. Two connections can be piped to the chiller 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 heating or cooling source can be hydraulically decoupled from the distribution system. The hydronic buffer tanks are all stainless steel construction with R-12 insulation, and an ABS jacket. Buffer tanks are available in 40, 60, 80, and 115 gallon capacities.

We also offer Hydronic buffer tanks with internal heat exchanger coils. The most common application for a buffer tank with coils is with water to water heat pumps. The bottom coil is piped to solar panels to reduce heat pump on time, and the top coil is piped to preheat domestic hot water to reduce water heater on time.
