  8. 8. Test Results<br />
  9. 9. Results: Solar Response<br />
  10. 10. Domestic Hot Water<br />Heat Rate:<br />Cost of Natural Gas: $.995/Therm<br />Cost Savings of Test: .04869<br />Gallons Used in Test: 22.5<br />
  11. 11. Domestic Hot Water<br />Savings per gallon .00322<br />Weekly Estimated Usage<br />Showers =472.5<br />Laundry =160<br />Dishes =20<br />Sink =75<br /> 727.5<br />Weekly Savings $2.34/Week $121.70/yr<br />
  12. 12. Solar Space Heating<br />Delivers: 100 MJ/dayCosts: 14.08 MJ/dayCOP: 7.10<br />
  13. 13. Total Gains from Useful Heat<br />
  14. 14. Cooling Tower<br />A tank response test was performed for 1 hour<br />The tank was cooled by 2.5 K (275 gal.) <br />11.12 Mj of energy was rejected <br />A standard efficiency A/C unit would provide 2.85 MJ<br />Actual savings depends on conditions of surrounding and usage pattern<br />
  15. 15. Cooling cycle: Storage Tank Response<br />
  16. 16. Cost Breakdown<br />Savings per Year: $428<br />7 year payback<br />
