The Stiebel Eltron DHC-E series tankless water heaters are the most advanced point-of-use tankless water heaters on the market today. The DHC-E 8/10 and DHC-E 12 both feature the same industry-leading thermostatic temperature control and flow and temperature based power modulation technology found in Stiebel Eltron's flagship Tempra whole house heaters. Set the desired temperature on the front of the unit and enjoy water temperatures between 86° (30°C), and 140° (60°C). Change the desired temperature at anytime. Advanced microprocessor technology ensures that the water temperature never deviates from the set point.
By producing hot water on demand only as it is being used, the DHC-E 8/10 is extremely energy efficient. A sophisticated water flow sensor recognizes when hot water is being used and when it has been turned off, so the unit will activate and deactivate automatically so it only runs when you are actually using water. This eliminates standby thermal heat losses associated with traditional tank type water heaters. Accordingly, you can expect to see a significant cost reduction over the operating cost of a conventional water heater.

| Do You Have Hard Water? |
|---|
|
If your water hardness trends above 7 grains per gallon (GPG) or 120 mg/l (ppm), you should consider hard water treatment prior to your tankless water heater. If your hardness exceeds 12 GPG or 200 mg/l (ppm), hard water treatment is strongly recommended. Hard water treatment helps maintain performance and efficiency, ensures optimal water flow and pressure, and protects your heater from pre-mature failure due to mineral build-up inside the heating module and other components.

The Stiebel Eltron DHC-E 8/10 combines the DHC-E 8 and DHC-E 10 into a single unit. Changing a jumper during installation allows this unit to act as either an 8 KW or 10 KW unit.

Stiebel Eltron DHC-E 8/10 Reviews
on-demand hot water
Product is working fine. The only thing I miss is that this new model doesn't have an indicator light to show that power is on until you start the water flow thru it. Other than than, it works great - Bruce
Other DHC-E Series Reviews
It’s ok
Honest review. It works. But you have to turn water pressure down in shower before it gets warm. Thinking about buying another and run water through both to get it hot. - Mkeith
I'm singing in the shower!
Temperature setting is only half way up and is delivering endless hot water making for a very enjoyable shower. - LD White
