You might want to read about heat pumps. They pump the heat you know. From colder outside into warmer inside. And they use (electricity that is) the fraction of heat energy that they pump in. So 100W electric heater gives you 100W of heat inside, but 100W heat pump can bring in 300W of heat from outside. So it's 300% more efficient at heating the inside of the house. |
