277 Volt 4,500 Watt Electric Tankless Water Heater

The Stiebel Eltron DHC tankless water heaters are designed for installation at the point of use. They heat water instantaneously as it flows through the unit. Stand-by losses are completely eliminated.

The heating elements are controlled by a flow switch and by an exclusive scald-guard thermostat, which keeps the water temperature within safe limits at all times. In addition, the DHC water heaters are equipped with a safety high-limit with manual reset. The rugged all copper design ensures many years of reliable service.

The models DHC 3-1, DHC 3-2 and DHC 4-2 are shipped with 0.5 GPM pressure compensating flow reducer/aerators that fit on most faucets. Flow controls and faucet aerators are highly recommended in conjunction with tankless water heaters.
