[EnergyPlus_Support] Hot Water Reset Savings?

["noelcrrl" <noelcrrl@xxxxxxxxx>]

Dear All-

I am tying to estimate the energy savings of implementing a hot water 
reset as a function of outside air.  The object was entered as shown 
at the end of this message.  When I implement the hot water reset, 
the energy consumption of the boiler does not change-no energy 
savings.  Why is this the case?  Does the boiler:simple object take 
into account water delivery temperature into its energy consumption 
calculation?

SET POINT MANAGER:OUTSIDE AIR,
    Hot Water Loop HW Temp Manager,  !- Name
    TEMP,                    !- Control variable
    82.2,                    !- Set point at outside low {C}
    -6.7,                    !- Outside low {C}
    65.6,                    !- Set point at outside high {C}
    10,                      !- Outside high {C}
    Hot Water Loop HW Supply Outlet;  !- Name of the set point Node 

Note, I am using the boiler simple object.  Thanks in advance.

Noel
