How to use water heater diagrams:

Air Speed. Starting from 1500 m3/h on the air flow scale draw a vertical line 1 till the air speed axis which makes about  3.2 m/s.

  • Supply air temperature. Prolong the line 1 up to the point where it crosses the outside air temperature (blue curve), e.g. -20°C; then draw a horizontal line 2 from this point to the left till  crossing  water in/out temperature curve (90/70 °C). From this point draw a vertical line 3 to the supply air temperature axis on top of the graphic (+21 °C).
  • Heating coil capacity. Prolong the line 1 up to the point where it crosses the outside air temperature (e.g. -20°C, red curve) and draw a horizontal line 4 from this point to the right until it crosses water in/out temperature curve (e.g., 90/70 °C), from here draw a vertical line 5 up to the scale representing the heating coil capacity (23.0 kW).
  • Water discharge. Prolong the line 5 down to water discharge axis at the bottom of the graphic 6 (0.28 l/s).
  • Water pressure drop. Draw the line 7 from the point where line 6 crosses the black curve to the pressure drop axis (12.5 kPa).
