Stiebel Eltron developed tankless electric water heating technology almost 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, Mini Series 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, super-compact design even allows for installation with the unit visible. Mini models are ideal for residential and commercial point-of-use hand-washing sink applications including: bathrooms, cabins and cottages, office buildings, stores, malls, warehouses, restaurants, and gas stations. Mini 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 Mini depends on the temperature of the incoming cold water, the water flow through the unit, and the size of the Mini model that is installed. Mini 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 Mini 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.

  • Mini 6 tankless electric water heaters are designed to provide warm water around 90 to 100 degrees F for hand washing at 1 high-flow (1.0 gpm) sink in a warm climate
  • Mini 6 models require 208/240 volt electric service, 1 dedicated 30 amp breaker, and 10 gauge copper wiring
  • The Nichrome (nickel-chromium) bare-wire heating element in all Mini Series models is controlled by a flow switch to prevent dry-firing and failure, and is additionally equipped with a safety high-limit with manual reset
  • Mini Series tankless water heaters were meticulously engineered in Germany and are manufactured in the US with great care and with the best available materials to provide years of trouble-free service

Rated 3.4 out of 5 by 7 reviewers.
Rated 5 out of 5 by Much easier than a standard water heater I had two standard water heaters in a small commercial building that were old and needed replaced. One unit was only servicing a bathroom sink and the other bathroom sink and a small sink in a kitchenette. I decided to install these instead and they weren't quite at the point of use but pretty close. The installation and wiring was really easy. My only gig was that the heater doesn't come with any fittings or hoses. So you will need to make sure you pick up what you need for your installation. But once you have what you need, which isn't much, the installation is very quick and easy. Now it takes the same amount of time to get hot water as it did before, so there's no noticeable difference from a user perspective. I would recommend this and plan on using these for a new building we're building. November 5, 2013
Rated 5 out of 5 by Works great for small volume Heater is small and compact so it allows use in tight spaces. It produces instant hot water and is perfect for a hand wash sink or small volume restaurant wash sink. It saves money by not having to heat hot water when not needed. October 16, 2012
Rated 5 out of 5 by Love it so far One word of caution - it is VERY sensitive to pressure flow. If you have even the slightest bit of debris n your faucet filter it will not give you hot water. July 29, 2014
Rated 1 out of 5 by Will not work The heater was installed properly and double checked. Power was verified. Water was never heated. It is a piece of trash! July 29, 2014
Rated 1 out of 5 by This product didn't work well for me In all honesty the instructions say to mount the unit right under the faucet, however we couldn't do that. We mounted the unit about 6 foot from faucet and got poor results. I sent it back. Had we been able to follow instructions we may have gotten fair results. May 6, 2014
