Stainless Steel Combination Tank for Heat Pumps
The Nexus Stainless Steel DHW Cylinder NXWT 200H+100L Buffer Tank Black combines domestic hot water storage with additional buffer volume for heat pump systems and professional HVAC installations. It is designed for applications where hot water comfort and hydraulic stability are needed in one compact solution.
Duplex 2205 Stainless Steel and Integrated Heat Exchanger
The inner tank is manufactured from Duplex 2205 stainless steel. The integrated AISI 316L corrugated stainless steel heat exchanger supports efficient heat transfer from the heat pump to the domestic hot water section.
Energy Efficiency Class A
With Energy Efficiency Class A, the high-quality PU insulation helps reduce heat loss, keeps stored water warmer for longer and supports lower energy consumption in heat pump systems. This makes the Nexus stainless steel boiler range an efficient choice for reliable hot water storage and long-term energy savings.
Compact Installation and System Stability
The buffer section increases system volume and helps the heat pump operate more smoothly, while the DHW section provides reliable domestic hot water storage.
