Operation: 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 efficiency and shorter equipment life.
What It does: The 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.
Highest Efficiency – No other buffer tank matches the Arctic Hybrid Tank in terms of heat loss efficiency. With a heat loss of 41% than the next comparable buffer tank, the Artic Hybrid Tank outperforms and save money and will never rust out!
