We replaced another tankless with the Stiebel Eltron Tempra 20 plus and it does everything we expected and more. The old one, from a now bankrupt manufacturer, was a NIGHTMARE. We can now forget that it a tankless system and our guests don't even know it is until we tell them...and it never runs out of hot water...ever.

I am totally in love with this. A month ago our water heater broke. With 10 people in our house and a baby on the way we thought we needed a BIG tank. Then we started looking at these on demand systems. WOW we love it! My husband and his handyman friend installed this in one day. If you are not so handy you would need an electrictian or if your state requires this ours does not. Ok point I love I can put all the little kids in a shower one after another so over 1 hr of constant hot. Both my husband , and i have taken a shower while the dishwasher is going with no problem. For the price of a new water tank I would highly reccommend this. I know we are saving on our electric as well just wont have exact figures until next month. ever want a LOng hot shower after the kids are in bed only to find out someone drained the tank? we no longer have this problem !

In 2005 I had a SETS tankless ,now the Hubble R220-3, installed following hurricane damage. I purchased the most powerful electric unit I could find, which resulted in my having to upgrade the electrical system by 50 amps. Because I purchased the unit online over a year before the electrician was able to install it (Florida '04 hurricane rebuild nightmare), I was stuck without a warranty. From day one, I had problems ranging from flickering lights to freezing then scalding water. You could run one shower or other device at a time, but a second supply would shut the unit off. Granted, for filling our jacuzzi tub, it was a miracle and when you wanted a long shower and did not mind continually tweaking the flow it was great. Also, there was a noticeable decrease in our electric bill. However, in all other respects, it was a constant headache. In July (Thank heavens!) of 2008, the unit failed completely. My wife and I debated whether to return to a conventional water heater, but we had built shelves in the place of the old heater and we did love the savings and convenience, when there was convenience.

I started researching companies and decided to purchase the 20 plus. I dropped down in power just in case the tech at the now defunct SETS was correct in suggesting that the inferior FPL power supply could not handle such a magnificently powerful units as ours. I now have a tweak of regret for that decision. To sum up the performance of the 20 plus: perfect for that size unit. Because I went with a smaller unit, flow is noticeably diminished when more than two sources are on at once. However, I have had both showers running simultaneously with hot water to spare (with lower pressure). Three and a half years now and not a hint of trouble.
