Hey... in my opinion, Stiebel Eltron are one of the best tankless water heaters in the market. I have a 3 bedroom-3 bathroom house and run hot water for the whole house with a DHC6-2 6KW 240v unit (please bear in mind that I live in the tropics - not the states). I first bought this Stiebel unit back in 2004 and it lasted me 14 years with no maintenance whatsoever at all (as a matter of fact I dont know if it requires maintenance). When this unit broke down (something about some micro-switches and burnt down resistor), I just decided to replace it with the same unit. So replacement was take old one down-put new one in with no hole drilling whatsoever. And I am clearly expecting 14 more years of service with this new one (lol). Best regards!

I want see how to install a 150litre horizontal wall mounted stiebel electron geyser. Don't you have a video for the installation?

[@zacharygross1207]

Thank you. I was a bit confused by the wiring diagram. I have the 29 trend and it calls for (3) 40 amp circuits. The diagram appears to have (2) 8/2 wires and an 8/3 on the far left. This video affirmed my suspicion that the third wire was intended to be a ground. Thank you.

I happy you found the video helpful. Take care

[@samanthahunt8099]

Did this unit end up working out well?

[@GB-ri7fg]

This looks like a great option for when a gas unit is not possible. If you are not getting water that is hot enough, the option is to turn down the flow. In some really cold climates, during the winter, you may even need to go down to one gallon a minute. It's still possible to take a shower but filling a tub can take a while. This is a very small unit and it's not intended for multiple faucets at one time. I called technical support for Stiebel and sent a photo of my (Square D) electric box. Paul Barnard from Stiebel is saying that this requires four slots. Two double pole 40 amp breakers. He is saying you cannot use single pole 40 amp breakers. Again, four slots are required. Two sets of double pole 40s are needed. I called twice and asked the same question. Be careful that you actually have four slots. Don't buy single-pole 40s. The unit might work on single pole 40s. That is not was Stiebel recommends.

[@kdub4pres]

The Tempra Plus models have a sensor that throttles the water flow automatically to keep the desired temperature. Fwiw.

[@GB-ri7fg]

Make sure you have four slots for double pole 40 amp breakers. That is that their Stiebel tech support told me.

[@LewisRenovation]

Yes, my unit needs x2 40a 240v circuits

[@TheIpadiphone]

Or you could get a 40 quad breaker

[@grungebox]

I’ve got the Steiber 12 240v model. It has a three wire hookup in it like the cables you are connecting. However, the cable I have coming from my circuit is a 4 wire cable. Would I connect 3 wires and cap off the 4th wire?

[@LewisRenovation]

I'd connect both the neutral and ground wires on your 4 wire cable to the ground on the water heater. I'm sure if you called tech support they'd tell you what to do.

It's been a year today since you uploaded this video, how is the Stiebel-Eltron working out for you? How cool is the winter in your area, did it have any trouble through winter?

[@LewisRenovation]

It works great. Only complaint, which probably applies to all tankless heaters, is that the faucet can't be just slightly open for it to turn on. Winters here are mostly 50's and 60's with occasional dips into the 20's or 30's.

[@matn7743]

@@LewisRenovation Nice. Thanks for the feedback mate.

[@kriszuzdi9760]

Dear Lewis, I would like to know, if you know of course. Has you measured or asked the Stiebel, if the temperature is set up only for 38 celsius degree,(not to 60 degree), and the device is 18 kw power, is it turning on to 18 kw power, or it is only partially (e.g. 13 kw to reach 38 degrees water? or the water demanding would be modified and the consumption is allways 18 kw/24kw... ? Do you know that? THank you for your answer. Regards Chris

[@LewisRenovation]

I believe the electrical consumption is relative to the set point and incoming water temperature. Hope this answers your question

[@jnpSacto]

The below quote is directly from www.stiebel-eltron-usa.com/products/tempra-series-whole-house-tankless-electric-water-heaters "Self-Modulation Energy Technology "Every Tempra® also has self-modulation. Self-modulation is sometimes confused with flow control, but it has more to do with the amount of energy used to heat the water. Self-modulation, sometimes call auto-modulation, ensures that only the least amount of energy is used at all times. Every Tempra® model continually monitors incoming water temperature, the flow rate of water through the heater, and the water temperature it produces. These sensors feed their readings into the unit’s proprietary microprocessor control which engages the heating elements in stages, as efficiently as possible, to achieve the water temperature set on the front panel, always using the least amount of energy necessary to heat the water." Hope this helps.

[@FnixGhod1]

I just finished mine. The only thing is that my water pressure is so good that on my tub, with a single handle faucet, the flow is too fast for the heater to heat the water (water saver shower head is fine). To save the heater units, it goes to low power mode. I just need to install a flow reduction valve inline to the tub and i'll be good to go!

[@LewisRenovation]

Hopefully it lasts a long time

[@bluespunn]

which model did you go with?

[@lydiaperez5320]

I need help. My dad hooked up one but I only ride a 40 amp break. and does not want to turn on the system.

[@LewisRenovation]

Sorry, I don't understand the question. Can you please clarify

[@anthonyrichmond6834]

So I noticed this water heater has one in and one out and the out (according to the description) is hot and the inlet is cold. How do you get the output for cold water?

[@LewisRenovation]

Put a T in front of the water heater and supply from there

[@anthonyrichmond6834]

So when you turn on the Coldwater, the water heater will just know you don’t need hot?

[@LewisRenovation]

The heater senses flow, so as long as there’s no flow through it due to hot water demand, it won’t turn on

There's an isolation on the inlet, outlet can be drained by opening up a faucet

Why was two 40 amp cables used instead of 1 cable of 240 volts ? the two cables hooked to 120 volts each I presume ??

They were x2 40 Amp 250v cables

[@luisgarcia6577]

What happens if you use only one neutral cable and bridge it?

[@LewisRenovation]

My understanding is that there is no current flow on the neutral with residential 240v

[@luisgarcia6577]

@@LewisRenovation I see, but there are 6 cables, I thought maybe the 2 black where hot cables, 2 white where neutral cables and the 2 grounds.. I just ask to lern more about how this works.

Now I understand the question. Both the black and white wire or hot. Each carries 120v but the are 180° out of phase so they total 240v when measured across them. The white wires are not neutral in this case

Those breakers you used are not correct. Those are twin single pole not 2 pole. Replace them with (2) 2pole breakers(they will take 4 full slots in your panel, not 2) and connect each set of wires to individual 2 pole breaker(2 white-breaker 1, 2 black-breaker2). The way you have it wired is totally unsafe.

[@rustxranch1220]

Paul, can't you use 1/2" dual pole breakers like the GE Q-line that consumes 2 full slots instead of 4? Also, any issue binding both grounds to the units ground block?

[@ProudDadVet]

First off, NEVER attempt ANY electrical installation without at least consulting a LICENSED Electrician. I am one, and I cannot tell you how much more it will cost you to have one come out and fix the job you did. 2nd, you MUST install the proper connector in the panel as well, I noticed you just ran the wires through the knockouts in the panel without any means of restraint. That is called a code violation and is just plain dangerous. 3rd... wrapping black electrical tape over the white wires to indicate they are conductors is just a good idea. Just saying. 4th, Neutral wires cannot be landed on a neutral bus with any other wire, ground wires can be loaded up to 3 wires under one screw. Your panel is a mounted code violation..... damn.... and what is that black wire on your Neutral bus???? WOW.

[@tori5977]

First!!!! Hahaha

[@lindaoliver4975]

A. You didn't install the NECESSARY Service, Flush Valves with Pressure Relief Valve. Biiiiig Problem. B. No Descaler either. UNless you do not have hard water... you probably won't need it.

awfully close to the main panel ... yikes.. not that you will ever get a leak... but imagine if you did..
