Solar cylinder made of steel with two smooth-tube heat exchangers, enamelled according to DIN 4753. Highly effective thermal insulation and low heat losses due to high-quality PU rigid foam insulation under the cylinder's foil jacket. Inner tank wall and heat exchanger corrosion-protected by enamelling and magnesium anode. Large heat exchanger surfaces ensure short heating times and high continuous hot water output. Side flange for additional heat exchangers and easy maintenance. Optimized diameter/height ratio for good temperature stratification. Solar pump group can be mounted directly on the cylinder Technical data: Energy efficiency class: C Storage volume: 285L Continuous storage output 80/60-10/45°C (heating) 20kW - 490L/h Performance coefficient (heating): 2.3NL60 Standby heat loss: 1.92kWh/24h Dimensions: Diameter: 600mm Height: 1794mm Tilting dimension with thermal insulation: 1898mm Weight: 130kg Heat exchanger surface area: Heating/Solar: 1.0/1.30m² Heat exchanger content: Heating/Solar: 6.6/9.0L Max. operating temperature: Primary heating water: 110°C, Secondary hot water: 95°C Max. operating pressure: Primary heating water: 10bar, Secondary hot water: 10bar Connections: Cold/hot water: 1
