The P/PS series buffer cylinders are versatile and efficient storage solutions that are ideal for operation with heat pumps. As a hydraulic separator, they optimise the efficiency and service life of the heat pump, reduce switch-on cycles and ensure a consistent heat supply. The diffusion-tight PU insulation minimises heat loss and enables use for heating and cooling buildings. The cylinder is also suitable as a small cylinder for fresh water stations. A connection for an electric immersion heater is also available. The PS version also includes a heat exchanger for connecting a solar thermal system.
