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 exchangers 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 Cylinder capacity: 385L Cylinder continuous output 80/60-10/45°C (heating) 20kW - 490L/h Performance index (heating): 4.8NL60 Standby heat loss: 2.41kWh/24h Dimensions: Diameter: 701mm Height: 1651mm Tilting dimension with thermal insulation: 1820mm Weight: 152kg Heat exchanger surface area: Heating/Solar: 1.0/1.80m² Heat exchanger capacity: Heating/Solar: 7.0/12.8L Max. operating temperature: Primary heating water: 110°C, Secondary hot water: 95°C Max. operating overpressure: Primary heating water: 10bar, Secondary hot water: 10bar Connections: Cold/hot water: 1
