Residential Water Heater Program

Marathon Water Heater Program

Sioux Valley Energy offers an unbeatable residential water heater program. We sell Rheem Marathon water heaters to members for $400 (plus applicable tax) for any size—50, 85 and 100 gallon. The special upfront purchase price of the water heater is in lieu of a monthly load management water heater credit or special rate. The Marathon is made out of a durable polyethylene jacket and withstands rust, denting, and corrosion. The water heater carries a lifetime tank warranty/6-years on parts for the original owner or a 10-year tank/1-year parts for rental/leased applications that have one water heater connected per unit/structure (only a 5-year tank warranty if one water heater is connected to multiple units). The water heater converts to a 10-year tank warranty if the home is sold. The water heater must be connected to our load management program for the lifetime of the water heater, which also complies with the Department of Energy regulations. Sioux Valley Energy does not deliver or install water heaters. The water heater must be paid for at the time of purchase and requires a pick-up or trailer for loading. Water heaters are available at the service centers in Colman, Brandon, and Pipestone. Please contact the Energy Services Department at 1-800-234-1960 to place your order. Orders can generally be picked up on the same day of the order. After the water heater is installed, the member must contact the cooperative to install/maintain the load management equipment. Sioux Valley Energy's wiring department does warranty and repair work should an issue ever arise.

The Marathon water heater program is only valid for residential domestic water heating purposes and is not available for commercial or agricultural applications; however, the Westinghouse water heater can be sold for non-residential use.

Former Alliant Energy customers are now eligible to purchase residential water heaters under this program.

The load management program allows our power supplier to shift demand during peak usage on the system. Due to the larger capacity and efficiency of the water heaters, most members are not inconvenienced by participating in the load management program.
