The Water heater is one of neglected appliances in homes, usually tucked away in some corner of the garage. We don’t pay much attention to it until it breaks. It has been around in its current form for a long time. It was invented in the 1889 by Edwin Ruud and it hasn’t changed much since then.

It consists of a 40 or more gallon cylindrical container with a gas burner or sometimes an electric element. It heats the water slowly and keeps it hot all the time. Its burner has a pilot light that is burning gas all the time and the main burner comes periodically into action to heat the water again because the water in the container has cooled off.

Well, that goes on day in day out even if the water is never used. That is because the water loses its heat to the surrounding. It is like having a kettle full of water on the cook top all the time. The newer tank water heaters are better insulated than before to reduce the standby heat loss but never the less they lose heat and the water must be constantly reheated. In today’s times where energy has become expensive and will become even more that is a total waste of energy and money. It burdens the environment even unnecessarily and contributes to earth warming and climate change.
