Water Heaters


Effective January 1, 2017 there will no longer be free water heaters given for remodels or new builds. Incentives will be given for water heater purchases as follows:

$150.00 rebate from K.C. Electric and $50.00 rebate from Tri-State when replacing an electric water heater with a Marathon electric water heater

$250.00 rebate from K.C. Electric and $50.00 rebate from Tri-State when replacing a gas water heater with a Marathon electric water heater

$300.00 rebate from K.C. Electric and $50.00 rebate from Tri-State for the purchase of a new Marathon water heater for a new home build only (Remodels or re-builds of any kind are not included in this rebate)

Marathon Warranty 

MR, MHD, and MTS models installed in residential, single-family dwellings must be registered within 90 days of installation to qualify for Marathon's Limited Lifetime Warranty. If the water heater is not registered within 90 days of installation, it is automatically covered by a 10-year limited warranty. Registration is the responsibility of the purchaser.

Take a closer look. And see for yourself.

One thing you'll notice right away is the tough but lightweight outer shell. And you're right, that is a new, innovative shape for a water heater. Some things you simply can't see because they're inside, like the heating elements and the inner water tank that will never rust, corrode or leak. And other things won't become apparent until you've owned a Marathon for a while — like the fact that it is incredibly energy efficient.

In fact, Marathon water heaters are so well made, they come with a Lifetime No-Leak warranty. A small detail many other water heaters simply don't have.

So if you expect your water heater to last a long time, make sure it comes with exactly what you expect.

Available in 40, 50 and 85 gallon models to members and non-members alike. However, no shipping is available--local pick-up at our Hugo, Stratton and Cheyenne Wells offices only.

The Marathon electric water heater offers these advantages:

  • Technologically advanced design is clearly differentiated from short lived steel water heaters.

  • It's the most durable water heater made, with a warranty to match.

  • Envirofoam™ insulation is completely free of CFC and HCFC ozone depleting gases. Marathon leads the way in environmental friendly manufacturing, design and operation.

  • Tank comes complete with a factory installed vacuum relief valve, ¾" brass tee and ¾" brass nipple for easy, professional installations.

  • Replaceable brass drain valve.

  • All wiring run in conduit for easy control wiring.

  • Seamless blow molded polybutene tank with no anode rod required for a corrosion free life.

  • High temperature, commercial-grade dip tubes for greater durability.

  • The filament wound fiberglass outer tank is designed to be more flexible and withstand more pressure than conventional tanks.

  • The unique high temperature dip tube is offset from the concave bottom, creating a "whirlpool effect" which helps prevent sediment build-up.
