Operating costs are estimated using the following assumptions:

• Units charge for an average of 4.5 hours per day
• Average monthly billing cycle equals 30 days
• House meets Act 222 insulation standards
• Rate for energy used by ETS units is $.062/kWh
• Units charge only during off-peak hours
  

Average Monthly Costs Per Unit Size

2 KW ETS unit:

2 KW x 4.5 hr x 30 days = 270 kwh/month
270 kwh/month x $.062/kwh = $16.74/month

3 KW ETS units

3 KW x 4.5 hr x 30 days = 405 kwh/month
405 kwh/month x $.062/kwh = $25.11/month

4 KW ETS unit:

4 KW x 4.5hr x 30 days =540 kwh/month
540 kwh/month x $.062/kwh = $33.48/month

5 KW ETS unit:

5 KW x 4.5 hr x 30 days = 675 kwh/month
675 kwh/month x $.062/kwh = $41.85/month

6 Kw ETS unit:

6 KW x 4.5 hr x 30 days = 810 kwh/month
810 kwh/month x $.062/kwh = $50.22/month

Note: Most members install an average of 10 KW of ETS to start.
Addition units can be purchased at a later date as "add-ons" to the original system.
