You can determine the preliminary heater size to meet
your requirements by using the chart below. But first,
you will need the following information to use the chart:

Determine your total hourly water usage during peak demand.
EXAMPLE: 6000 gallons / 60 minutes = 100 GPM
Determine the water temperature rise required
EXAMPLE: inlet 60ºF, outlet need 160ºF = temp rise
of 100ºF

The chart suggests a model 5000 to meet these specific
needs.

Rated performance is based on 60ºF inlet water with 100ºF temperature rise. For higher temperature rating, consult factory.

Variations in the QW heater design may be required to achieve all flow parameters. Please consult factory if required temperature rise (ºF _out - ºF_in) is less than 60ºF.
Standard ratings are based on 1000' elevation. Burners are subject to 4% deration for each additional 1000'.
Tabulated flow rates represent 99% efficient heater operation when inlet water temperature is 60ºF or below.
A.) Model x 1000 = BTU/hr capacity through Model 8000.
B.) Models 10.0 through 35.0 x 1 million = BTU/hr capacity.
