eSense develops solutions designed to balance hot water needs with sunlight and electricity costs by enabling users to operate their water heaters during off-peak hours whenever possible. The eSense system lets users decide how they want their hot water, with programmable options that enable a small, consistent amount of water each day, with different amounts during different hours of the day, as well as weekly water planning. eSense promotes the optimal use of water heaters, preventing unnecessary activation and saving money and time.
