Nexus Next A+ NEXT-500 XL-LE1 Duplex 2205 stainless steel heat pump water heater with Energy Label A+, extra-thick PU insulation and Ø32 mm high-flow heat exchanger.
The Nexus Next A+ NEXT-500 XL-LE1 is a vertical Duplex 2205 stainless steel heat pump water heater for domestic hot water systems and professional HVAC installations.
The A+ energy label is achieved with extra-thick PU insulation, reducing standby heat loss and improving long-term energy efficiency.
The Ø32 mm AISI 316L corrugated heat exchanger supports high heat-pump flow rates, low flow resistance and efficient transfer of heat to the domestic hot water tank.
Duplex 2205 stainless steel provides high mechanical strength, excellent corrosion resistance and a long service life for professional installations.
