Marathon Point-of-Use water heaters are built to the
same specifications as our full-size Marathons. These
point-of-use water heaters are great for applications
where the larger water heaters won’t fit, or for special
uses such as:
• Apartments and condo’s
• Restrooms in offices and commercial buildings
• Cabins, camps and recreational property
• Lavatories in large homes away from central water

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.
These units are designed to
meet or exceed ANSI
(American National Standards
Institute) requirements and
have been tested according to
D.O.E. test procedures and
meet or exceed the energy efficiency requirements of NAECA,
ASHRAE standard 90, ICC
Code and all state energy efficiency performance criteria for
energy consuming appliances.
Before purchasing this ppliance,
read important energy cost and
efficiency information available
from your supplier.
