There are not many people like that in the first world. Most of them are in the U.S. Pacific Northwest where the electricity comes from hydro or wind power, so production does not take 3 units of thermal power per 1 unit of electricity. That is what I recall from the EIA. Next is the home electric water heater.

Electric water heating is more common that resistance electric space heating. However, as I said there is no reason to think Rossi or anyone else is limited to a COP of 3. In the most recent tests, the first COP was 6 and the second was 3 but that was very conservative. Probably it was closer to 4. No matter how difficult it is to control the thing at higher COPs, methods will be found, and then perfected. People are able to control extremely dangerous reactions, such as igniting small amounts of gasoline without causing the entire vehicle to explode. This is done all over the world in billions of automobiles every day. Automobiles seldom burn. When they were first developed Otto cycle engines and diesel engines burned and exploded often. - Jed
