45AC-BT13-H SpacePak Solstice 13 Gallon Stainless Steel Hydronic Buffer Tank with Single 3kW Element

As a hydraulic separator, buffer tanks separate the energy source loop (heat pump/boiler) from the hydronic flow in the distribution system (air handlers/emitters). Hydraulic separation is used primarily in systems whereflow rates from the source to the distribution vary or with applications utilizing variable speed pumps. The heating or cooling source can be hydraulically decoupled from the distribution system. Buffer tanks are used as hydronic buffer tanks in systems having several low BTU cooling or heating loads calling at different times or systems operating below the design load condition. Buffer tanks store the additional system volume and energy currently not utilized by the system for use on additional calls for heat leading to more efficient system performance and longer equipment life. There are four piping connections built into the buffer tank units (1 1/2" NPT on BT-13-H, BT26-H and BT40-H, 2" NPT on BT80-H). Two connections can be piped to the distribution system.
