thermostats savings calculations
How your savings are calculated
Step 1 determine heating and cooling saved2079 hours - 1726 hours = 353 heating hours saved 1118 hours - 928 hours = 190 cooling hours saved |
Step 2 determine energy savings for heating36,000 BTU/hr heating capacity / 8.2 HSPF = 4390 W (efficiency-adjusted) 4390 W / 1,000 W/kW = 4.39 kW 4.39 kW x 353 hours of heating saved = 1549.67 kWh saved |
Step 3 determine energy savings for cooling36,000 BTU/hr cooling capacity / 15 SEER = 2400 W (efficiency-adjusted) 2400 W / 1,000 W/kW = 2.4 kW 2.4 kW x 190 hours of cooling saved = 456 kWh saved |
Step 4 determine total savings1549.67 kWh saved on heating + 456 kWh saved on cooling = 2,006 kWh saved yearly 2,006 kWh yearly savings x 15 year expected life = 30,085 kWh lifetime savings 2,006 kWh saved x $0.118 per kWh = $236.67 total yearly savings 30,085 yearly savings x $0.118 per kWh = $3,550.04 lifetime savings |
Savings calculations are presented as an example of potential savings; actual savings may vary based on use, utility rates and other factors.
Calculations are based on national averages and assumptions and may be adjusted for a more accurate estimate of individual savings.
