High Performance and High Efficiency
Vaughn's Hydronic Buffer tanks are designed to be used in closed loop heating systems with low-mass boilers, geothermal systems, wood boiler installations, and chilled water applications. A buffer tank helps to improve system efficiency in hydronic systems operating below the design load conditions by preventing the low-mass boiler from short cycling. System short cycling can cause the heat pump or boiler to operate less efficiently and may also lead to premature equipment failure. Vaughn buffer tanks are manufactured using a heavy gauge steel inner tank surrounded by a minimum of 2" foam insulation, resulting in very low standby heat loss. The vessel is protected by a high-impact composite jacket material which cannot rust or corrode.
The hydronic buffer tanks are available in sizes ranging from 10-119 gallons, and is manufactured with four 1.5" tappings for primary/secondary connections. An immersion temperature control well is located in the middle of the tank to ensure accurate temperature sensing for heating and geothermal applications, along with a conveniently located boiler drain for periodic sediment removal. Also included is a fitting for an air eliminator at the top of the vessel, reducing air accumulation (and the potential for corrosion) in the system.
