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 unit
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

Additional units can be purchased at a later date as "add-ons" to the original system.
