How much electricity (kWh) does a residential oil burner use while operating?

Question

I have an oil burning water heater and I know it has an electric pump, an electric blower, and an electric igniter. I estimate it runs for about 100 hours per year. I am trying to learn how much electricity it uses while running. This will help me know the cost to run it. Thanks for any help with this.

Answer 1

I measured my Carrier forced air system in preparation for backup with a generator. Took about .7 kw (700 watts) to start either the burner or the blower, and when heating ran about .4 kw. If it runs for the full hour, it would be .4kWh times whatever your electric rate per kWh is.
