Features
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 STIEBEL ELTRON DHC tankless water heaters are ideal for restrooms or kitchenettes in an office or commercial / industrial setting, such as:
- Office Buildings
- Gas Stations
- Stores
- Schools
- Malls
- Hotels/Motels
- Warehouses
- Restaurants
- Manufacturing Facilities
In a residential setting, they are suited for the following applications:
- Bathroom Sinks
- Kitchen Sinks
- Laundry Areas
- Small Cabins
- Boats/RVs
The DHC 3-1, DHC 3-2 and DHC 4-2 models 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.

Hydraulically controlled pressurized instantaneous water heater for undersink installation and for supplying one or more water taps, i.e. a shower and a hand basin or two hand basins. It has a tubular heating element system in a pressurized copper container and is suitable for calcareous-poor water. The instantaneous water heater is switched on automatically by the hydraulic control as soon as a minimum flow rate is exceeded. The temperature of the flowing water is determined by the heating output of the instantaneous water heater, the flow rate and the temperature of the added water.
