Joe, Electricity more efficient for heating? A lot of the electricity production is using oil, with around 35% efficiency to make the electricity. Heating with oil have 70 to 85% efficiency in burners. I would not give anything for this manual, the author lacks knowledge and understanding. A pity that it is a women who wrote it, because now I am going to be accused of being a male chauvinist. It does however not effect the fact that it is much more efficient to heat with oil, than with electricity.
