Product Overview

DHC-E 12 models are ideal for residential or commercial point-of-use sink applications including: bathrooms, offices, stores, malls, warehouses, restaurants, and gas stations. They may also work for single low-flow shower use under some conditions, and can be easily removed for over-wintering a seasonal cabin or cottage. They are electronically controlled and can be set to deliver water at the temperature you need. They heat water instantaneously and endlessly at 99% efficiency as it flows through the unit. Because they do not store hot water like tank water heaters, they have no stand-by energy losses. Venting is not necessary and the compact European design can be installed with the unit visible. A DHC-E is considerably smaller than a tank, saving space and allowing flexibility to determine the best location for installation. The number of sinks a DHC-E can supply depends on the temperature of the incoming cold water, the water rate through the unit, and the supply voltage. Refer to the DHC-E Sizing Guide to determine model suitability, especially for whole house use. Call Stiebel Eltron at 800.582.8423 with any sizing questions. Stiebel Eltron invented tankless electric water heating technology more than 90 years ago, and is still the industry pioneer and world leader today, with an engineering and manufacturing tradition of excellence.

Customer Questions & Answers

I purchased this water heater from HD while my house was being built. When I finally got moved in, the water did not work. That was after spending about $1,200 in electrical, and another $400 in extra plumbing. Sadly, by the time it was discovered to be defective, it was out of warranty. Don't make the same mistake I did by buying early. This is a Totally piece of hardware, and a useless waste to me. I am extremely disappointed.
Asked by: David
Thank you for your reply, however I called the general HD # you provided, the lady was most unhelpful. She gave me the phone of the manufacture and said that was all she could do. Have a nice day. Thanks for nothing.

So what is the major difference between the Tempra 12 and the DHC-E 12 12.0 kW 2.34 GPM??????

So what is the major difference between the Tempra 12 and the DHC-E 12 12.0 kW 2.34 GPM??????
Asked by: mer
Both units produce the same amount of hot water as both are 12KW. The major difference is the size of the unit. The DHC-E is smaller than the Tempra 12 making it easier to fit into smaller locations if need be.

DHC-E 12 12.0 kW 2.34 GPM Point-of-Use Tankless Electric Water Heater is rated 4.1 out of 5 by 18.
Rated 2 out of 5 by from Very limited use Beware that all tankless water heaters are severly limited because they have to balance temperature against water volume. The higher the temperature or longer the run between heater and faucet, the less water volume can be heated. As a result, water pressure will suffer. This is a point of use product which means it has to be located next to the faucet. It cannot heat enough water for a household (i.e., where the hot water has to pass through any length of pipe) nor is it adequate for use in a shower unless you like low water volume. Ideally, this is best suited for a kitchen or bathroom sink with an aerator.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.

If you set the temp at the midpoint (120 degrees) the water pressure can overcome the heating element and I'm on a well. The water comes out hot then alternates hot to cold. if you turn on only the hot faucet it works fine. This is on a bathroom sink, if you're using this for a shower I'm sure you'll need to set the thermostat to a much higher setting.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.
