Differential pressure bar (x 100 = kPa)
Hot water capacity Free air discharge capacity If the temperature of the air differs from 15 °C, the discharge capacity from the graph can be corrected by multiplying it by the following equation:
289 273 + T (T is the actual temperature) It may be assumed that the temperature of the air is the same as the temperature of the water.
