Country: United Kingdom

Stiebel Eltron Mini compact tankless point-of-use models excel at supplying warm water at a constant temperature for hand washing at a sink. They are ideal for residential or commercial hand-washing sink applications. The model must be carefully matched to the flow rate of the sink for proper operation. Mini tankless water heaters heat water instantaneously and endlessly at 99% efficiency as it flows through the unit. Unlike tank water heaters, they save energy because they have no stand-by energy losses. The sleek, small design allows installation with the unit visible. Venting is unnecessary. Use the Sizing Guide and Technical Data Chart to determine the correct size for your application. Call Stiebel Eltron at 800.582.8423 with any questions. Meticulously engineered and carefully manufactured, Mini tankless water heaters are designed for years of trouble-free and energy-saving usage.
