RVS NEXT NXWT 200L -100L buffer
Nexus Next A+ NEXT 200+100 2-in-1 Heat Pump Boiler with Buffer Tank
The Nexus Next A+ NEXT 200+100 combines a Duplex 2205 stainless steel domestic hot water boiler with a lower 100 litre buffer tank in one compact unit.
The A+ energy label is supported by extra-thick PU insulation, reducing standby heat loss and keeping stored heat available for longer.
The integrated Ø32 mm AISI 316L corrugated heat exchanger is designed for modern heat pumps with higher flow requirements and efficient heat transfer.
The lower buffer section increases system volume, improves hydraulic stability and helps reduce frequent heat pump cycling.
