Get the superior, reliable, and energy-saving tankless electric water heater for point-of-use applications.
The Stiebel Eltron Mini line was designed for point-of-use use. The Mini heats up water instantaneously while it flows through the unit. Any standby heat loss is completely eliminated.
Its heating elements are efficiently controlled by a flow switch. In addition, all Mini water heaters come with a safety high-limit and a manual reset. It is made with meticulous German engineering and the highest quality materials to ensure that every Mini lasts many years of trouble-free service.
Tankless water heaters are recommended for use with flow controls and faucet aerators. The Mini 2-1 is restricted to a maximum output of 0.32 GPM. The Mini 2-1, 2.5-1 and 3-1 models come with a 0.5 GPM pressure aerator / flow reducer. The Mini 3.5-1 and 4-2 feature a 0.66 GPM pressure compensating aerator / flow reducer. All aerators can fit most faucets. No drains, pressure relief valves, or circulating pumps are needed.
