OPERATION

GENERAL

4 | DHC-E WWW.STIEBEL-ELTRON-USA.COM

3. General

The 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 ﬂ ows through the appliance.

Due to the absence of stand-by losses, the appliance offers greater

energy efﬁ ciency than storage type water heaters.

26_02_02_1086

The input of heat into the water is electronically controlled. The

appliance will deliver any water temperature between 86°F (30

°C) and 140 °F (60 °C). Please set the desired temperature using

the knob on the front cover.

Note

For reasons of appliance efﬁ ciency and durability (sca-

ling), the optimum temperature setting lies between 86°F

(30°C) and 120°F (50°C).

In case the “Power” light is ﬂ ashing while the appliance operates,

the water ﬂ ow rate exceeds the heating capacity of the appli-

ance. Reduce the hot water ﬂ ow rate in order to let the appliance

achieve the set point temperature. The maximum temperature is

electronically limited to 140 °F (60 °C). In case you have questions

regarding the way you plan to use the appliance, please call our

technical service line, see last side.

4. Troubleshooting

Symptom Possible Cause  Solution

No hot water not enough flow rate to

activate appliance

clean faucet aerator or shower

head

Water not hot enough water flow too high reduce water flow rate until

light on front cover stops

blinking

If you cannot remedy the fault, notify the contractor who installed

the appliance. To facilitate and speed up your enquiry, please pro-

vide the serial number from the type plate (000000-0000-000000).

including, but not limited to warranties of merchantability

and ﬁ tness for a particular purpose. Manufacturer shall

not be liable for incidental, consequential or contingent

damages or expenses arising directly or indirectly from any

defect in the Heater or the use of the Heater. Manufacturer

shall not be liable for any water damage or other damage

to property of Owner arising, directly or indirectly,

from any defect in the Heater or the use of the Heater.
