A buffer tank serves several important functions in a hydronic heating system. Fluctuating temperatures and flow rates can cause the geothermal heat pump to operate inefficiently or even shut down. A buffer tank mixes the water coming back from all of the zones that are circulating to maintain an even temperature of water flowing into the geothermal heat pump. It also maintains a consistent flow of water through the geothermal heat pump’s coil. A buffer tank also helps prevent short cycling by providing a larger thermal mass to prevent the thermostat from starting and stopping the geothermal heat pump too often.

If you’re looking for a buffer tank that will make your ground source hydronics system more efficient, be sure to consider the HSS hydronic buffer tank from B&D Manufacturing. The HSS series hydronic buffer tank is a non-pressurized stainless steel hydronic buffer tank that incorporates the pumps, controls, and valves all into a single unit, eliminating the aggravation of mounting everything. Instead, simply plumb the lines, wire the thermostat and heat pump, and fill the system. The non-pressurized tank keeps the air out of your systems. B&D Manufacturing custom makes each HSS buffer tank.

The HSS non-pressurized hydronic buffer tank offers a number of important features:

  • Insulated stainless steel construction
  • 12, 20, 30, 40, 60, and 80 gallon tank sizes
  • Designed for 6 to 10 gallons per ton of buffer volume
  • 1 ¼”, 1 ½”, or 2” inlet and ¾” or 1” ball valve outlets
  • 115V pump on hydronic heat side
  • 230V pump on water side
  • Built-in hydronic pump relay standard sensor for one-state heat, two-stage heat, or heating and cooling
  • Pump selection based on flow and foot of head circuit
  • Water-side only 3 heat pump circuit maximum
