AURATON buffer tanks are an indispensable addition to a heat pump installation. Filling the tank with water or a mixture of water and glycol ensures that the pump will not freeze at low temperatures. In addition, the buffer will prevent too frequent on/off cycles of the heat pump, which translates into a longer life of the heat pump.
