Lochinvar 30 Gallon Stainless Steel Hydronic Buffer Tank

Lochinvar's Stainless Steel Buffer Tanks are designed provide thermal storage volume and hydraulic separation of the boiler or heat pump and the building distribution system. A properly applied buffer tank will reduce cycling (short cycling), which will lead to longer runtimes, higher efficiencies and longer equipment life. Squire buffer tanks can be used in geothermal, chilled applications, and any system with low-mass boilers. Thermal Storage Hydronic buffer tanks are utilized to provide thermal storage volume when the system demand is less than the lowest firing rate of the boiler. This occurs most often when there are "micro" zones in the distribution system whose demand is below the minimum firing of the boiler. Under these conditions the boiler fires at its minimum rate, which is more energy than can be absorbed by the distribution system, and shuts off because of high return temperatures before the "micro" zone's call for heat is satisfied. The boiler system continues to receive a call for heat and ...
