The Stiebel Eltron Mini 3.5-1 tankless water heater is designed for installation at the point-of-use, or under the sink. 120V - 3.5kW Mechanical

The Mini heats water instantaneously as it flows through the unit. Stand-by heat losses are completely eliminated. The efficient heating elements are controlled by a simple flow switch. Additionally, all Mini water heaters are equipped with a safety high limit with a manual reset.
