Yeah yeah, but the watt is used for electric power for our context here. I guess I would never talk about gas efficiency in terms of watts or kilowatts used, as was suggested. I figured someone would call me on that one

Yes, gas appliances are usually described by their heat output, BTU. And BTU/hr to describe usage, and mmBTU to describe savings.
