Question: What size circuit breaker is needed?
Document: In remodeling my kitchen I found I needed to move my refrigerator to where my 50 gallon water heater sat, so I decided to go tankless.I bought the Stiebel Eltron Tempra 36 from AMAZON (Compact Appliance) for a little over $700.00 (Great Price!
I have (had) a Steibel Eltron Tempra 36. I installed it 2 years ago. It was correctly wired w/ 3 60-amp circuits, 6ga wire with ground.Today, one of the circuit boards caught on fire. It was only by the grace of the Lord Jesus Christ himself that it happened when my girl was in the basement putting laundy in the dryer. I kid you not.
There are no electric units on the market that are as powerful as the propane ones, so make sure you've done your homework before installing.The unit WILL draw its rated power (36kw) if you ask it to, so make sure you have enough power. It takes THREE 60 amp breaker PAIRS, which is a LOT of panel space. Check this also before installing.In operation the thing works flawlessly and does exactly what it says in the manual.
Although this is an electric tankless/continuous  water heater, and will consume a lot of energy when in use, it saves you a lot of energy when not in use. I had this installed for my guest bath, overkill for the size, but you NEVER run out of hot water. It was easy to install and set up. Be sure not to take short cuts with the installation of the proper wiring to support its operation. It is not worth the risk of overheating the wiring and causing a fire.
Works fantastically well. Was straight forward to install. We barely have it into the residential setting for temperature and it is more than hot enough for everything.
We love the dial on the front of the unit that allows us to adjust the temperature in seconds. It takes up NO SPACE to speak of, and we were able to mount it to the wall and hook the plumbing up easily ourselves. We let the electrician hook up the power to the unit. We now store tools in the space where the hot water heater was.We expect to save about $25 a month over the old 50 gal tank we had...we shall see! !
We installed this heater for a customer and less than a year in service it stopped working. Stiebel-Eltron is difficult to deal with. It took us over one week to get a replacement heater for the homeowner and now find out that they don't cover the labor to reinstall the heater. I will not sell their products to my customers anymore, I thought they were a company that stands behind their products and installers.
We bought a Bosch electric tankless water heater in 2008. It was the biggest one and we had our house wired just for this. By 2010, we could not take a hot shower. It would fluctuate between freezing and cool. We bought this Stiebel Eltron because of the great reviews and we are so glad we did. We have all the hot water that we could ever want.
We are on our second Tempra 36. Not because we had a problem with the first one, but because we had one in our house in Virginia and when we moved to Oklahoma and built a new house, it was the first thing we purchased. We have never had any problem with this tankless and recommend it to everyone we know. With four children, countless showers and loads of laundry, it has never let us down.
Very happy with the purchase. You will most likely need professional help installing. Make sure you have the spare capacity before ordering. And the flow rate is restricted compared to our old heater. We can still take two showers at the same time but we can tell a difference. We set ours to 109 degrees for usage. Looking at the power draw with a ammeter it is really loafing with respect to its full capability. I would definitely buy again.
Answer: yes
