Test Dates:		April 22, 1999 to May 14, 1999
Pool Type:		2 Outdoor pools: 2600 sq ft. and 1250 sq ft.
Other Factors:		Minimal wind exposure

The San Diego Marriott has its own gas meter which measures only the energy used to heat their two swimming pools.  They take a daily meter reading at 2 am every morning.  We kept track of gas used for one week without useing HEAT$AVR.  Then we installed a pump which automatically injected the daily dosage of HEAT$AVR into the pool for one week.  HEAT$AVR was added to the smaller pool manually during this same week.  We noted the energy useage for this week with HEAT$AVR in the pools.
