Test Dates:		June 19, 1999 to July 24, 1999
Pool Type:		The test was conducted on the wader pool The wader pool has approximately 300 square feet
Other Factors:		Gas heat Zero precipitation during the test period

The engineering team connected a gas meter to the heater for the wader pool. They kept track of the gas used for one week without using HEAT$AVR. Then a daily dose of 0.75 ounces of HEAT$AVR was added to the wader pool manually for one week. They noted the energy usage for this week with HEAT$AVR in the pool.

CONTROL PERIOD (no HEAT$AVR used)
6/19/99 to 6/26/99
 

Natural Gas used during period		95.3 Therms
Average temperature during period*		63 degrees F.

TEST PERIOD (0.75 oz. in wader pool daily)
7/17/99 to 7/24/99
 

Natural Gas used during period		62.7 Therms
Average temperature during period*		69 degrees F.

*All weather statistics were taken from the National Weather Service website at http://www.wrh.noaa.gov/sandiego

TEST RESULTS
 

Reduction in gas use from HEAT$AVR		32.6 Therms
Value of Gas Saved**	Per Week Per Month	$10.43 $41.72
Cost of HEAT$AVR Used	Per Week Per Month	$2.16 $ 8.64
Net Savings from HEAT$AVR	Per Week Per Month	$8.27 $33.08

** cost of gas = $0.32/Therm

CONCLUSION

The result of this two week test was a 34% reduction in energy use, which equals potential net savings of approximately $396.96 per year. In other words, for every dollar spent on HEAT$AVR for the wader pool, Four Seasons Resort Aviara will save approximately $4.80 (Payback ratio of 4.8:1). It is important to note that this will be the annual savings for the 300 sq. ft. wader pool. This does not include the potential savings for the main swimming pool, which has 4600 sq. ft.

HEAT$AVR will save energy in every pool, but heat cost savings vary according to several factors including the type and cost of fuel used, and hours of swimmer use per day. Tests have shown savings ranging from 15% (at high-use municipal pools), to 40% (at low-use condominium pools).

Based on previous tests with similar sized, gas heated pools, The Four Seasons Resort Aviara is likely to see savings of between 20% to 30% in its main swimming pool.
