It is the cold months again and we started using hot water for bathing. Last night my wife and I had a friendly argument on the cost of heating water. I am using the stove to heat a kettle of water that I use for my own bathing and my wife needed 2 kettles. What if we use the electric water heater which is plugged and the other end has a round object that is submerged in a pail of water. I couldn't answer which is cheaper so I am now in the process of computing.
