Input Variables: (listed in shaded cells)

1.  Plants annual operation hour  (Enter variables):

     Length of shift in hours                        
     Number of shifts per day                      
     Number of annual operating days            

     Total annual hours of operation

2.  Required hot water volume in gallons per minute (gpm) =

     gpm

3.  Required temperature rise (DT) (Enter variables):

     Incoming water temperature (^oF)
       Required outlet hot water temperature (oF)
       Temperature rise required (oF)

4.  Plant's fuel cost rate per thousand cubic feet ($ / mcf)
      (Enter variable:)

     Note: $ / mcf = $ / therm x 10

5.  Plant's calculated Btu / Hr requirements using the following heating   
     energy demand equation:

gpm x 500 x temperature rise (DT) = mmBtu / Hr required

   ^{Required mmBtu / Hr}

6. Estimated unit efficiencies (Enter variables):

   % Existing equipment

   % QuikWater Unit

7. Calculation of estimated hourly energy savings.

mmBtu / Hr x	$ / mcf	=
/ (divided by)	%	=
/ (divided by)	%	=
- minus		= $ Savings / Hr

8. Return on investment breakdown.

Daily Savings (est.)
Monthly Savings (est.)
Annual Savings (est.)
