Water Heaters

Choosing an energy efficient electric water heater can help reduce monthly water heating bills.

Electric water heaters offer high efficiency performance, quiet operation, better indoor air quality and safety, and greater durability. San Isabel Electric’s water heater program gives members a free State electric water heater when entering into a load control agreement. These water heaters are 95% efficient and carry a 6-year warranty. Members and non-members also can purchase a Rheem Marathon water heater, which is 95% efficient and carries a lifetime tank warranty.

Heat pump water heaters are also optimal, high-efficiency water heaters that use electricity to move heat from one place to another instead of generating heat directly. These water heaters can be two to three times more energy efficient than conventional electric resistance water heaters and have an excellent lifetime payback, especially when paired with solar.


SIEA has a $50 rebate available if you purchase a fuel switching water heater. For more information call (719) 647-6250.
