Stiebel Eltron developed tankless electric water heating technology 90 years ago and continues as the industry pioneer and world leader. Our engineering and manufacturing tradition of excellence means you can depend on the performance and reliability of our products. Instead of storing hot water, DHC-E models are tankless, heating water instantaneously and endlessly as it flows through the unit. They are 99% efficient with no stand-by energy losses, unlike tank water heaters. The DHC-E is considerably smaller than a tank, saving space and allowing flexibility to determine the best location for installation. No venting is necessary, and the sleek European design even allows installation with the unit visible. The DHC-E 12 is ideal for residential or commercial point-of-use sink applications including: bathrooms, offices, stores, malls, warehouses, restaurants, and gas stations; and also single low-flow shower use. It is perfect for seasonal cabins or cottages as it can be easily removed for over-wintering. The DHC-E 12 is electronically controlled and can be set to deliver water at the temperature you need. The number of sinks a DHC-E can supply depends on the incoming cold water temperature, the water flow through the unit, and the supply voltage. Refer to the DHC-E Sizing Guide and Temperature Rise Chart under 'More Views' to determine model suitability, especially for whole house use. Call Stiebel Eltron at 800.582.8423 if you have any sizing questions.

  • Professional installation recommended
  • DHC-E 12 tankless electric water heaters provide hot water for multiple low or medium-flow sinks, or for single shower whole house use in both cool and warm climates
  • DHC-E 12 models require 208 or 240 volt electric service, 1 dedicated 60 amp breaker and 6 gauge copper wiring
  • A DHC-E 12 is perfect for a seasonal cottage or cabin as endless hot water means enough hot water for everybody's shower
  • DHC-E water heaters can be set on the front panel to supply water at the exact temperature desired from hand-washing temps of 86 degrees to as high as 140 degrees F if required by health codes, and can also be set to limit output temperature to 109 degrees F
  • DHC-E 12 tankless electric water heaters are 99% efficient and typically result in savings of 15-20% in comparison with electric tank-type water heaters
  • Installation should be as close to draw off points as possible to make the wait for hot water as short as possible and maximize energy savings
  • DHC-E tankless electric water heaters do not need pressure relief valves, drains, or circulating pumps
  • DHC-E tankless electric water heaters are exempt from seismic code and must be installed vertically with the water fittings pointing down
  • DHC-E tankless water heaters are ETL Listed for compliance with CSA and UL safety standards in the US and Canada
  • Water connections for DHC-E water heaters are 1/2 in. NPT and should be detachable (such as braided steel flex connectors or isolation valves) to allow for easy servicing
  • Overheat safety protection and thermal protection reset are standard
  • See warranty for complete details of the 3-year residential and commercial warranty against defects in workmanship and materials under normal use

Rated 4.3 out of 5 by 15 reviewers.
Rated 5.0 out of 5.0 by Well Built & Functions As Described I bought this unit and installed in our small church. We use it to heat water for two restroom hand wash lavs and one kitchen sink. The unit is able to supply all three outlets with ample hot water simultaneously. Installation was easy and straight forward. I would highly recommend this unit to anyone with the need to heat water for a few low flow water outlets. May 31, 2012
Rated 5.0 out of 5.0 by Soo far so good I use hot water for dishes and shower 2gal a min is plenty I would say a bath or hot water cloth washing would require a larger unit or more tha 2 people other wise I love it. I also put an inline filter seeing I'm on we'll water. June 26, 2012
Rated 5.0 out of 5.0 by Worked like a charm I used this as a supplemental heater for an upstairs bathroom. There was a lag time when the hot water kicked in from a heating coil on my oil fired heater. I installed this unit in line with the hot water feed, it heats the water for the shower and a sink as needed and then shuts off when not needed. Works like a charm for this purpose, the water for the shower is hot for the entire time in the shower. The unit was easy to install except you need to know that if you are going to use stainless steel flex hose that you need adopters to go from 1/2" IPT to 3/4" GH or garden hose thread. No problem, they carry the adopters in the plumbing section at Home Depot. Used Shark Bite connectors, the adopters and the whole thing took about an hour to install, the wire taking the longest time. Works perfect for this supplemental application. May 18, 2014
Rated 5.0 out of 5.0 by Excellent Shower is at opposite side of the house from our water heater. It took too long to get warm water to the shower. With this system, the water heats up when we need it. Although we only installed it a month ago, we love it. February 5, 2013
Rated 5.0 out of 5.0 by Love it. Just installed 2 of these in our cabin this past week and they worked very well. The cabin is on a well and the incoming water is very cold so I put them in series iseries in order to get a good flow. July 10, 2013
Rated 4.0 out of 5.0 by It has saved me money in lower electric bills This product was easy to install, I have knowledge of plumbing and electrical skills. My electric bill has been slightly lower every month since this has been installed. It isn't large reduction, however it is only used for dishwasher (2-3) a week, and hot water from kitchen sink. Best savings, not heating hot water while on vacation. August 16, 2014
Rated 4.0 out of 5.0 by Very Good Prouct Have only had installed for a week, but it operates fine. Temp will fluctuate as incoming water temp changes, but no serious problem. It may require a minor adjustment to hot water knob after a few seconds and incoming water temp stabilizes. April 10, 2012
Rated 5.0 out of 5.0 by Works like a champ... The kitchen sink took way too long to even start gettin' warm, so the plumber disconnected that line and connected the new heater, and a Y-valve on the cold water line. The electrician had to climb up in the attic and run some very thick copper wire back to the fuse box. Those two installers cost close to double the cost of the heater itself. But once all that was over, now we're living in luxury with near instant hot water ! I have to remind everyone to not overuse because it really sucks some juice, when in use ! Good news is the rest of the time, about 95% or more, not a drop of power is being used, so I think for us it is slightly more economical than the old way, which barely worked. The water it plenty hot and seemingly endless. The electrician and plumber were true professionals and worth the money to have it done right. Wife and I are very satisfied ! Jim, in Olive Branch, MS.
