Seeing as electric heat is 100% efficient, all he has to do is multiply the
KW times the rate his electric company charges.

By doing it this way, he will be able to arrive at an accurate figure on
total operating costs of l.p. vs. electric.

The original question of "tell me how I go about computing cost of
operation
of an appliance" can only be answered by knowing how many BTUs he needs.
Then he can figure out how long an electric heater will have to run.
All that calculating isn't necessary. All he has to do is multiply his
gas
usage by his heater's efficiency, then divide that by 3,413 to find out
how
many KWs he needs.

But he does not know how to figure the operating cost of those kWs. He
seems to know what he needs, (thus the 2,000 watt figure) just not the
cost
of operation compared to propane.
