The latest water heating technology revolution
| Our newest models, DHC Trend, DHC-E Trend, and
DHC-E Plus incorporate our Direct Coil
™
heating
system. Stiebel Eltron’s most advanced technology,
our Direct Coil
™
has proven worldwide to be
exceptionally low-failure, including in our Mini
™
water heaters, with outstanding added benefits.
The robust and trouble-free Direct Coil
™
heating
system is self-cleaning for superior limescale
resistance, and includes added benefits of faster
heat-up time, lower latent heat retention, and more.
Switchable models | Expanding on the well-
received innovation of our DHC-E 8/10, the entire
line of new Direct Coil
™
models are switchable
at installation to one of two power outputs. This
provides extraordinary flexibility for an installation
while simplifying model choice. Switching power
outputs is as simple as changing a jumper.
Largest Point-of-Use with Exclusive Advanced
Flow Control
™
| In addition to now offering the
largest point-of-use model available with 14.4 kW
of power, the new Direct Coil
™
DHC-E models are
available in our Plus configuration.
The Direct Coil
™
heating system in the DHC-E Plus
models includes Advanced Flow Control
™
. Patented
in Germany, and exclusive to Stiebel Eltron tankless
heaters, Advanced Flow Control
™
has been a feature
of our whole-house Tempra Plus models for years.
If hot water demand exceeds working capacity,
Advanced Flow Control
™
automatically maintains
consistent temperatures by slightly reducing flow.
Now available in the DHC-E 8/10-2 Plus and DHC-E
12/15-2 Plus, Advanced Flow Control
™
allows
installation of a single water heater to satisfy
multiple sinks. A Direct Coil
™
DHC-E Plus will provide
the correct temperature water at multiple sinks at
the same time, without delivering colder water if the
system is overloaded by one too many taps being
opened.
Superior, Reliable & Energy Saving
Performance | In addition to the special benefits
of Direct Coil
™
technology, the new models include
the benefits that are part of the entire Stiebel Eltron
electric tankless line.
Ideal for both residential and commercial point-of-
use sink applications, these new Direct Coil
™
models
heat water endlessly on demand at 99% efficiency.
They have no stand-by energy losses because they
do not store hot water like tank water heaters.
No venting is required and the compact European
design can be installed with the unit visible.
Micro-processor control, flow sensor, and our newly
patented air detection system completely eliminate
dry-fire. And of course these new models have a
safety high-limit with a manual control. Activation
rate for all new Direct Coil
™
models is a low 0.264
GPM.
Model-specific features | Intended for trouble-
free installation without user tampering, DHC Trend
models have no screen or temperature adjustment.
They are sized by choosing the correct power output
for the particular flow rate and temperature rise
needed for an installation.
DHC-E Trend and DHC-E Plus are equipped with
digital display screens. Desired output temperature
is easily set using the dial and display on the cover.
These models also have additional electronic
features that include memory settings, flow rate and
energy usage display, and an
ECO mode.
While these models excel at supplying water at the
desired constant temperature, the amount of hot
water and its temperature depends on the incoming
cold-water temperature and the size of the model
installed. The correct model size should be chosen
using our Sizing Guide. As always, our renowned
technical support department is available for advice.
Superior, Reliable & Energy Saving
Performance | All Stiebel Eltron electric tankless
water heaters
have flow and temperature sensors.
Auto-modulation in electronic models ensures that
heating elements are engaged in stages, achieving
desired water temperature with the lowest possible
energy usage. In all models, input and output
water temperature and flow rate are continually
monitored. This smart microprocessor Electronic
Temperature Control technology ensures steady
output at the set point temperature even as flow
rates vary up or down. Tankless electric water
heaters from other manufacturers don’t maintain
steady temperature as the incoming flow rate varies.
Sleek Design Fits in Anywhere | Due to their
compact dimensions and no need for venting, these
water heaters may be installed in areas where
Simply the Best
larger devices will not fit, and close to draw-off
points to minimize piping runs. The attractive
housings may be left unconcealed in many
applications.
Code Compliance Made Easy | A water
temperature required by code can simply be dialed
in on all electronic models. The accuracy of the
water temperature is guaranteed by sophisticated
electronics. The DHC-E Classic, Trend, and Plus
models, and Tempra
®
models can supply up to
140 °F (60 °C) water when health codes call for
it. They can also be set internally to limit output
temperature to a maximum of 109 °F (43 °C) where
scalding water is a hazard. When lower, non-
scalding temperatures are needed, the advanced
electronics of these models ensures what
you set is what you get.
Mini
™
-E and DHC-E models have optional externally
attached mixing valve assemblies for installations
where UPC code compliance is a necessity. No need
to worry about an internal mixing valve to go out of
adjustment or wear out.
At the heart of Stiebel Eltron’s most advanced and
revolutionary Direct Coil
™
heating system is a robust
nichrome heating coil and a bullet-proof
poly-amide composite
heating chamber.
*Max input water 149°F; max input water that would be heated 131°F; max. temperature output 140°F.
