Particulars on the interpretation SDE


(Minimum pressure safety valve 3 bar)

System contents: Panel Radiator: 9l / kW // sectional radiator: 12 l / kW // under floor heating: 18 l / kW // radiant panels (70/55 ° C): 9l / kW // Aluline (60/45 ° C): 4l / kW // ventilation / cooling: 6-8 l / kW Expansion coefficient (in%) as a function of temperature for approximate calculation: 90 ° = 3.55 = 2.86 // // 80 ° 70 ° 60 ° = 2.22 = 1.65 // // 50 ° = 1, 15 // 40 ° and cooling systems = 0.72 = 1.14 // water-glycol mixture

Coefficient of expansion (in %) depending on the temperature for rough calculations: 90°=3,55 // 80°=2,86 // 70°=2,22 // 60°=1,65 // 50°=1,15 // 40° and cooling system=0,72 // water-glycol mixture=1,14
