SOLUTION:
The completed Worksheet 1 for this example is shown in Figure 2. The Adjusted Peak Hour
Demand is 195 Gallons per Hour. From Table 1 we see that a MT050G is required.
Use Figure 4b to determine the boiler size required to achieve a 195 GPH First Hour Rating
with an MT050G. From Figure 4b we see that a boiler output of approximately 102,000 BTU/hr
is required. Install a boiler with a 102,000 BTU/hr output.
