Following is a fax received from Pacific Gas & Electric regarding natural gas consumption comparing the Kestrel S35 with a customers existing ¼ bag drum/afterburner coffee roaster.

The test was performed to determine if the customer qualified for a Pacific Gas & Electric rebate for installing energy-saving equipment.
Answer: Yes, the Kestrel S35 easily saved enough natural gas to qualify for a rebate. However, because the equipment was installed prior to the test, the rebate was not paid.
Lesson: Contact your utility company and arrange for a rebate before installing a Kestrel!

Page 1 -- Test Methodology Test performed by Pacific Gas & Electric to determine relative efficiency of customers existing roaster vs. Kestrel S35.

Page 3 contains the data sheet for these tests.
