Digital Temperature control
Stiebel Eltron tankless water heater has a convenient digital dial to control the heat. You can choose any temperature between 86 Degree f (30DegreeC) to125DegreeF (52DegreeC). This wide range makes it possible to have a hot shower at whatever inlet temperature of your water is.
Micro mini size
I may have exaggerated the size by the phrase micro-mini, but it is really very tiny compared to other tank or tankless water heater. With 4.1 x 7.9 x 14.2 inches specifications, you do not need to hide behind a cabinet; it is already near to invisible. And with a 6-pound weight, it is very light to carry.
Stiebel Eltron DHC-E 12 maintains a steady temperature even though the variable flows of water. Its electronic temperature Control compensates for fluctuations of flow rate and the incoming water temperature and maintains a constant temperature output. Their smart microprocessor technology monitors information from the flow sensor and two temperature sensors—the microprocessor then adjusts the heating elements.
Reduces electricity consumption
Once you switch to Stiebel Eltron DHC-E12 Electric Tankless Water Heater, you will experience at least a 20% reduction on your electricity bill compared to a tank water heater. This point of heat technology only runs when it senses a flow of water. While you are on vacation, out of home in the daytime, your heater will not be working or consuming power (unlike tank heaters).
No venting needed
If you have had a gas-fired tankless water heater, you know why I bullet this point as a good feature. It is not very much of a hassle, yet it definitely is a concern; whether your house has that nook where hanging your heater will get enough space for ventilation. In some cases, venting needs are big enough not to let you put the heater inside the home. You may require a venting valve, duct systems to let the extract go away. With Stiebel Eltron DHC-E12 Electric Tankless Water, such worries can rest, as it does not need any venting at all.
- Hot water on demand

- For both residential and commercial use
Cons with solution
Not suitable for high demand
Stiebel Eltron DHC-E 12 is barely borderline with a home of two people, so if you are planning to install it for a home with any more people, then it is not suitable.
In cold inlet temperature of 32-degree Fahrenheit, Stiebel Eltron DHC-E, 12 can support 4 faucets at maximum with a flow of GPM of 0.5.
In a warmer climate, 65 degrees or above, Stiebel Eltron tankless water heater can support 5 faucets with 0.5 GPM and 2 faucets if GPM is 1.5. So whether you can use it for home with people more than 2 or 4 depends more on how often your faucets are busy at the same time and your inlet water temperature.
Not good for hard water condition
Stiebel Eltron water heaters are functional only for water conditions with PH 7, so before buying one, get your water level tested.
German company Stiebel Eltron water heaters are susceptible to the hard water condition. Especially if your water PH is very far from 7, then it is possible that after some time, it may show signs of not turning off even though no water flow is detected. This eventually will lead to bigger issues and the breaking down of the heating system. To avoid it, you can use water softener extraction available on the market in your reserved tank. It would help if you cleaned the heater valves, too, for longevity periodically.
Solely run by electricity.
It has a single power source to depend on, which is electricity.
It runs on electricity, with no option to use a dual power source like battery or gas. However, in the USA, most places have electricity support to run in the home; still, if you are looking for a water heater that can also run on battery or when Stiebel Eltron DHC-E 12 is not for you.
