The tankless hot water heater is an innovative way to save money on your water-heating bill. Storage-type hot water heaters lose heat all day long consuming more energy than any other job in the home except space heating. Tankless hot water heaters only heat the water you need as you're using it. You never store hot water again. You never wait for water to heat up again. You never run out of hot water!

Traditional water heaters pose a danger to small children. Water does not have to be heated to extreme temperatures for extended use as it does in a tank water heater. With the old type of hot water heater it is necessary to run hot water from the tank and right away you have to relief the extreme temperature with cold water to make it comfortable to the touch. Tankless water heaters are set to a pleasant temperature of your choice and you dont have to use the cold-water side again. There would no longer be extremely heated temperature to cause burns, disfigurement and perhaps death.

There are a bacterium that grows naturally in water and is found in rivers, lakes, and streams. The bacteria are found in the water supply of every building, at moderately low concentrations. The bacterium only becomes dangerous when circumstances constructive to its growth exist. Legionnaire's Disease is a type of pneumonia infecting the lungs. 10,000 - 100,000 cases of Legionnaires Disease occurs in the U.S. each year. Disturbingly, about 5% - 15% of these cases are grave, mostly in smokers, the elderly and in those whose weakened immune systems make them vulnerable to bacterial infections.

The bacterium has been found to thrive in domestic tank type water heating systems in which temperatures are kept at steady levels for extended periods of time. The ideal temperature for the growth of this particular bacterium is 95 - 131 degrees F. The incubation period is 2 - 10 days. Unfortunately this is the temperature maintained in the average home water heater, 24 hours a day, all year long. In other words, all the circumstances that are needed for the growth of this disease are there in your standard residential conventional tank water heater.
