In the Home Energy Saver, users are allowed to select
between electric and gas stoves. The following equations describe the method used to
calculate energy consumption by stoves
Electric
EC = power x usage_{day} x 365
where: EC = Annual
energy consumption in kWh
power = energy
consumption rate of stove (kW)
usage_{day} = hours of use per day for all
burners combined
365 = days per
year
For electric ranges, the power consumed is assumed to be 1
kW for the purposes of this model (PG&E 1995).
Gas
EC = (burner_rate x usage_{day} x365) + pilotLight
where:
EC = Annual
energy consumption in therms
burner_rate =
energy consumption rate of all the burners combined (therms/hour)
usage_{day}
= hours of use per day for all burners combined
365 is days per
year
pilotLight =
energy consumed by the pilot light (therms/year)
For gas ranges, the rate of energy use is assumed to be
0.09 therms/hour and pilot light consumption is 17 therms/year (PG&E 1995).
The default usage is 1 hour per day for both electric and gas ranges.
Users are able to alter the inputs for stoves and ovens
only in the detailed inputs model. The table below details the initial assumptions
used for calculating stove energy.
