Electric room heaters are better than heating the whole house.
It is often thought that it is better to heat just one room that is in use rather than the whole house in order to save energy. And typically that means employing an electric space heater. The truth is these are major energy suckers. It is impractical and expensive to have a space heater running for a long period of time. If the room where it is used is super insulated and is really the only room being used for a long time, then it might make sense. But for most of us, space heater efficiency is a big myth.
If you really want to cut energy costs for heating, try turning your thermostat down a degree or two. This actually saves a whole lot of heat. And if you're feeling chilly, have extra socks, sweaters, and lap rug at the ready so you don't even notice that little difference.
