Save Money. Save Energy. Electric Water Heaters.

In an effort to promote energy conservation Northern Electric Cooperative sells residential Marathon electric water heaters. These residential water heaters play an integral role in keeping electric rates low and saving energy. 

Northern Electric homeowners who connect their water heater to the load management system may qualify for hundreds of dollars worth of rebates on a new water heater. Only one water heater rebate can be redeemed per structure every 10 years. Members may also be eligible for a $6 per month bill credit for having a water heater connected to load control. The load control system allows Northern Electric, in partnership with power-supplier East River Electric Power Cooperative, to cycle the water heaters on and off during times of peak demand on the system. Cycling water heaters on and off can save energy at times of high demand while also cutting down overall power costs. 

Only Northern Electric members can purchase a new 85, or 100-gallon residential Marathon water heater from the co-op. Members can purchase a water heater at the Northern Electric main office in Bath or at the Redfield office from 8 a.m. to 4:30 p.m. during normal business hours. Purchases and pickups on weekends will come with an additional charge. 

For more information about residential water heaters, or water heaters for commercial properties, please contact Northern Electric at 1-800-529-0310.
