99% thermal efficient
EcoSmart, Design for a Sustainable Future
EcoSmart tankless electric water heaters heat water only when needed unlike traditional water heater tanks. EcoSmart tankless electric water heaters are 99.8% thermal energy efficient compared to only 65% with a tank heater. Since the water is only heated when called from an application, there is little thermal heat loss compared to constant heating of a large amount of water with a tank heater.
