Tankless electric water heaters for point-of-use

Superior, Reliable & Energy Saving
Performance |

electric water heaters
temperature sensors. Electronic models
feed their readings into proprietary
microprocessor controls. Auto-modulation
ensures that heating elements are
engaged in stages, achieving the water
temperature desired, with the lowest
possible energy usage. Both the input
and output water temperature and the
flow rate are continually monitored.
This smart Electronic Temperature
Control microprocessor technology
ensures steady output at the set point
temperature even if flow rates vary up
or down. Tankless electric water heaters
from other manufacturers don’t maintain
steady temperature if the incoming flow
rate varies.

Best Warranty in the Industry | Stiebel

Eltron has an enviable track record of
engineering excellence and product
quality. The three-year parts warranty is
unique in the industry. You can depend
on a Stiebel Eltron tankless electric water
heater

for many years to come.

Superior Engineering in Every Way |

Electronic models are completely silent
in operation. Mechanical models are
virtually silent. All models feature an
exclusive design that prevents failure
from dry-firing, plus manual safety high­limit cutoffs.

Simple Design of Plumbing System |

There is no need for a T & P valve, drain
or mixing valve. The design of the hot
water plumbing system is very simple and
straightforward.

Sleek Design Fits in Anywhere | Due

to their compact dimensions, these water
heaters may be installed close to draw-off
points to minimize piping runs and also in
areas where larger devices will not fit. The
attractive housings may be left unconcealed
in many applications.

Seismic Proof Construction | These

tankless water heaters are not subject
to seismic code. There is no need for
preventative construction, as required with
bulky water storage heating systems.

No Venting Required | The units are

electric and require no venting. This allows
for installation possibilities not possible for
gas units.

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.

UPC code compliance is a necessity. No
need to worry about mixing valves that
go out of adjustment and wear out. At
the same time, when lower, non-scalding
temperatures are needed, the advanced

®

electronics of the DHC-E / Tempra

ensure

what you set is what you get.

Electronic Model Temperature Control |

The Mini-E is factory-set internally to deliver
maximum 100 °F (38 °C) water temperature. It
can be field set or custom ordered to deliver

output water temperature between 68 to
140 °F (20 – 60 °C).

This is our recommendation for overcurrent protection sized at 100% of load. Check local codes for compliance if necessary.

Tankless water heaters are considered a non-continuous load.
