Once the furnace is running check your elec. meter. See
Reading electromechanical meters
inElectricity meter - Wikipedia, the free encyclopedia
Let's say your house was using 5 kw just before the furnace kicked off when the t'stat was satisfied.
Then temporarily raise the 'stat setpoint by 10F. The second stage should kick on and you should see the usage probably double, if you have a second stage.
