Table I: General Specifications
Piping—Domestic Hot Water Supply Heaters
Table I above provides data for selecting
1.Flow rates are based on water hardness as meas- ured in grains per gallon.
Soft:
Medium:
Hard:
2.Maximum Flow Rates:
0133 | 22 GPM |
45 GPM | |
90 GPM | |
200 GPM |
3.Pressure drop values (ΔP and SHL) and minimum pipe sizes are for
4.Sizing based on heater and tank being placed 5 feet apart. The equivalent length of pipe, valves and fittings in the system is as follows:
2" NPT = 75 Ft
3" NPT = 85 Ft
Additional pipe fittings will increase the system head loss.
5.Select a pump based on the water hardness, flow, and system head loss.
6.If heater is more than two stories above the tank, consult the factory.
NOTE: GPM flow rates are limited by maximum acceptable velocity through heat exchanger tubes. Heater models 0514 through 1826 may be provided with an integral
MINIMUM INPUT ADJUSTMENT: Model Types WH have minimum input ratings as specified on their indi- vidual rating plates. Minimum input controllers have been
