Pre-assembled valve unit for solid fuel buffer storage heaters, for maintaining the boiler return temperature at a high level. An optimum boiler return temperature prevents the temperature from falling below the dew point and boiler sooting, i.e. less environmental pollution and a longer service life for the boiler. The loading valve unit can also be used to improve stratification in buffer storage systems.Technical data:- Operating voltage: 230 V / AC, 50 Hz- Max. flow rate: 2600 L/h- Circulation pump: Grundfos UPM3 Auto L25-50- Max. operating temperature: 110°C - Max. operating pressure: 110°C110°C- Operating pressure max.: 10 bar- Housing material: brass- Length: approx. 400 mm- Operating voltage drive: 24 V / AC, 50/60 Hz- Mains adapter: 230 V / AC, 50/60 Hz, 300 mA- Control temperature: 10-80°C freely adjustable
