236 200 1003 500 L stainless steel DHW cylinder with XL 316L heat exchanger, black finish and all connections in one vertical line.
The 500XL-LE1 is built for projects that require a larger domestic hot water reserve. Its higher storage volume helps cover peak demand while keeping the technical layout clear and serviceable.
The 40 m corrugated AISI 316L heat exchanger supports strong heat transfer from the heat pump to the stored water. This is useful for systems with multiple draw-off points or longer hot water usage periods.
Duplex 2205 stainless steel, PU insulation and the black casing provide a durable construction for demanding HVAC projects and long-term operation.
