According to Energy Star, tankless water heaters can be 24-34% more energy-efficient than conventional storage tank water heaters.

Space-Saving Design

Electric tankless water heaters are compact and can be installed in small spaces. Whether you’re living in a cozy condo or a spacious house, these units can fit just about anywhere. No more worrying about dedicating a large area for your water heater.
