Performance Check
Heat of Extraction(HE)/Rejection(HR)
Record information on the Equipment Start-up Form
Equipment should be in full load operation for a
minimum of 10 minutes in either mode – WITH THE
HOT WATER GENERATOR TURNED OFF.
1. Determine ow rate in gallons per minute
a. Check entering water temperature
b. Check entering water pressure
c. Check leaving water pressure
Once this information is recorded, nd
corresponding entering water temperature column
in Specication Manual for unit.
Find pressure differential in PSI column in Spec
Manual. Then read the GPM column in Spec Manual
to determine ow in GPM.
2. Check leaving water temperature of unit.
FORMULA: GPM x water temp diff, x 500 (antifreeze)
or 500 (fresh water) = HE or HR in BTU/HR
A 10% variance from Spec Manual is allowed.
Always use the same pressure gauge & temperature
measuring device.
Water ow must be in range of Specication
Manual. If system has too much water ow,
performance problems should be expected.
