The Stiebel Eltron Mini™ tankless water heaters are designed for installation at the point-of-use. 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 manual reset.
Flow controls and faucet aerators are highly recommended in conjunction with tankless water heaters. The Mini™ 2-1 is internally restricted to 0.32 GPM. The Mini™ 2-1, 2.5-1 and 3-1 models ship with a 0.5 GPM pressure compensating flow reducer / aerator. The Mini™ 3.5-1 and 4-2 models ship with a 0.66 GPM pressure compensating flow reducer / aerator. All aerators are designed to fit most common faucets. No pressure relief valve, drains, or circulating pumps are needed.
