Nexus PAWT XL-LE1 horizontal 200 litre stainless steel heat pump water heater with 28 mm heat exchanger for heat pumps and domestic hot water. Duplex 2205 inner tank, 20 m AISI 316L corrugated coil, PU insulation and frosted-metal outer casing.
The RVS Hygiëne boiler PAWT-200H XL-LE1 is a stainless steel heat pump water heater designed for domestic hot water (DHW) production in modern heat pump systems and professional HVAC installations. It supports reliable hot water performance, stable flow and efficient heat transfer.
The inner tank is manufactured from Duplex 2205 stainless steel, offering high corrosion resistance, mechanical strength and long service life. This makes the series a premium stainless steel alternative to standard enamelled or painted steel cylinders.
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.
The integrated 32 mm AISI 316L corrugated stainless steel heat exchanger is designed for efficient heat transfer from the heat pump to the domestic hot water tank. The technical layout supports low flow resistance, accurate control and professional installation.
