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 models are tankless, heating water instantaneously and endlessly as it flows through the unit. They are 99% efficient, and, unlike tank-type water heaters, have no stand-by energy losses. No venting is necessary, and the sleek, compact European design even allows for installation with the unit visible. DHC models are ideal for residential and commercial point-of-use sink applications including: bathrooms, cabins and cottages, office buildings, stores, malls, warehouses, restaurants, and gas stations. DHC models are sized based on the flow rate of the sink you are plumbing for hot water. The temperature of the hot water delivered by a DHC depends on the temperature of the incoming cold water, the water flow through the unit, and the size of the DHC model that is installed. DHC models excel at supplying water at a constant temperature rise but must be carefully matched to the application in order to operate properly. Refer to the DHC Sizing Guide and Temperature Rise Chart under 'More Views' to determine which model you need. Call Stiebel Eltron at 800.582.8423 if you have any sizing questions.

Rated 2.9 out of 5 by 8 reviewers.
Rated 3.0 out of 5.0 by Second one in 3years This is the second heater we buy in 3years, exactly when the warranty expires it broke down and we had to get another one, the electrician came and changed it easily. February 4, 2014
Rated 5.0 out of 5.0 by works much better than other product I purchased This was the second tankless heater i purchased, replacing one that did not heat at all. This product heats a sink quite well, was easy to install, and looks good enough you dont have to hide it in a cabinet. July 3, 2012
Rated 5.0 out of 5.0 by Works as described I followed the guide for selection and it was right on. I would have purchased the next size up due to our faucet flow rate and the incoming water temp, however, the existing electrical wiring limited me to 30 amps. I am very happy with the unit though. I wish it had a more durable electrical enclosurel to use conduit or flexible conduit. The enclosure provided is for an electrical cord. Also, I installed a filter before hand because I was told sediments can really mess these up. March 25, 2014
Rated 1.0 out of 5.0 by Slow Flow still not hot enough I especially had a dedicated breaker installed for this unit. There is no temperature control on the system. to allow water to get hot you have to turn down the pressure. We regulated the flow as low as it could go but the water still does not get hot enough. This is a terrible unit! I don't recommend it to anybody!!! February 20, 2015
Rated 1.0 out of 5.0 by Very Dissapointing I bought this to heat water for a single sink in my workshop. I installed it on a dedicated 240V 30A circuit. It barely heats the water at all. It's a shame because the unit is well made and looks nice. There are some instructions for reducing the water flow to increase the temperature, but even at low flow rates it does not get hot. It's OK if you just need arm water for washing your hands etc (As I do) but as a hot water source it's more or less useless. January 6, 2014
Rated 1.0 out of 5.0 by False Advertising I bought this unit, hoping that I could use it for one sink in a bathroom. After reading the manufactures claims, had they been true, which they are not I would have been pleased, but this unit is useless. After installing, using 10/2 wire on a 30 amp 220V dedicated circuit, letting it burn in for half an hour the water temp on full hot was barely just past warm. After turning down the flow setting all the way until the water was just coming out almost a trickle the water temp was no better. This thing was a waste of my time and now I'm taking it out and returning it. If you want to spend 200 bucks and have water trickle out at 85 degrees go for it, if you need HOT water do not buy this product, it is a totally useless piece. I will never buy another product from this company. February 10, 2013
Rated 4.0 out of 5.0 by Works, but know its limits The product itself is of high quality and easily installed. Its impartant to realize this product will only perform (as pointed out in other posts and in the instructions) as well as the water you are supplying to it. In a nut shell, it heats water 35-40 degrees, period. You can increase that a little bit by choking the flow, but if you are in a cold reagon, say a cold garage where the water is coming into the unit at 40-45 degrees; you are going to get 70-75 degrees water at the sink. I guess you could say its Seasonably Sensitive... It will work for washing hands and such in the winter, and of course in the warmer months it will be quite functional as a hot water source.

Rated 3.0 out of 5.0 by I paid too much for this item.On line it was way less. Instructions on cleaning filter were vague. I tried to turn the wrong nut and twisted it. And can I get a refund for the model ?? February 19, 2014
