1kW * hours used per day = a kWh

1kW * hours used per day = b kWh

1kW * hours used per day = c kWh

Tota l da ily energy usage = a+b+c kWh

Fac tor in lower effic ienc y if model >10 years Tota l da ily energy usage *1.3

Estimate monthly expend iture: Tota l da ily energy usage * 30 * $0.25

Note: Ac tua l energy consumption

depends on fac tors suc h as roomtempera ture, thermosta t setting , frequenc yof ma intena nc e, etc . (c an be ~40% more)
