Before you buy another water heater…Save your Energy!
When heating water with electric immersion elements, 100% of the
element’s energy goes into the water. The difference between an
energy efficient model and a standard heater is in its ability to retain
the temperature of the water. The Marathon heater will outperform
any other heater of comparable size.

For the purpose of this test, water was heated in two heaters of the same size. Power was then cut-off to the
heaters and temperatures were monitored until they fell below the temperature of 110°F. We recommend the
heater be operated at factory settings. Water hotter than 120°F can cause scalding injuries.
