Get the superior, reliable, and energy-saving tankless electric water heater for point-of-use applications.
Stiebel Eltron DHC tankless water heaters were designed for point of use installations. They heat water instantaneously while it flows through the unit. Any standby loss is completely eliminated.
Heating elements are controlled by a built-in exclusive scald-guard thermostat and flow switch, which keeps water temperature within safe limits. In addition, DHC water heaters come with a manual reset and a safety high-limit. The rugged all copper design ensures reliable service for many years.
Tankless water heaters are recommended for use with flow controls and faucet aerators. The DHC 3-1, DHC 3-2 and DHC 4-2 feature 0.5 GPM pressure compensating aerators / flow reducers that fit most faucets.
