IMPORTANT DECISIONS REQUIRED BEFORE
SIZING
1. Boiler DOE Heating Capacity – The indirect-fired water
heater will provide the rated performance only if used in
conjunction with a heat source with a DOE heating
capacity (Heat Output) at least as much as the minimum
noted in Table 3. If the heat source has less capacity, the
output of the tank will be reduced. To determine the
approximate reduction in output from the tank use the
following formula:
New Rating = (maximum continuous draw rating) x
For example, what would the continuous draw rating be if a 50-
gallon indirect-fired water heater were installed with a heat
source having a DOE heating capacity of 55,000 BTU/h?
New Rating
= 98 gal/hr x (55,000 BTU/h)/(65,000 BTU/h)
= 98 gal/hr x 0.846 = 83 gal/hr
