RVS Hygiëne boiler NXWT 300H 100L buffer: Stainless Steel Combination Tank for Heat Pumps
The RVS Hygiëne boiler NXWT 300H 100L buffer 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.
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.
