Figure 9.2: Piping Method #1 - Heat Only
Example (contd.)
Total fittings in Indirect Water Heater Loop:
5 90 Elbows
2 Turns in Tees
1 Swing Check
2 Isolation Valves
Calculate total equivalent length from Table 9.7:
20 Straight Pipe + 5 Elbows x 2.75 + 2 Turns in Tees x 5.5 + 1 Swing Check x 7 + 2 valves x 0.6 = 52.95
Equivalent Feet Straight Pipe. From Table 9.6, we see that smallest circulator which will pump at 8 GPM
through a FCM120 with 52.95 equivalent feet and an indirect water heater pressure drop of 3 ft is a Taco 0014.
