4. General
The DHC tankless water heater differs from conventional storage
type water heaters in several ways. It does not store hot water.
Instead, water is heated instantaneously as it flows through the
unit. The powerful heating elements are activated by a flow switch
as water is drawn from a hot water faucet connected to the DHC.
Due to the absence of stand-by losses, the DHC has greater energy
efficiency than storage type water heaters.
The temperature of the hot water delivered by the DHC depends
on the wattage of the heating element, the temperature of the
incoming cold water, and the water flow rate through the unit.
In order for the DHC to operate properly, it must be carefully
matched to the application.
In case you have questions regarding the way you plan to use the
DHC, please call our technical service line at 800-582-8423 (USA and
Canada). For service outside the U.S. and Canada, please call us at
USA 413-247-3380. You can also e-mail us at info@stiebel-eltron-
usa.com or fax us at 413-247-3369.
The DHC can be used for hand washing type applications in the
U.S. and Canada:
- Restroom sinks in commercial/industrial facilities and homes
- Kitchen areas in commercial /industrial facilities and homes
- Cabins
- Special uses in photo developing shops, laboratories etc.
The DHC can also be used for whole apartments and homes in
warm climate zones such as the Caribbean region, Central Amer-
ica and Mexico due to the higher ambient water temperatures.
