User questions & answers

Question:	We have a 500sq' apt. 1 kitchen sink, 1 lav sink and tub/shower. This tankless heats water to both sinks but nothing to the tub/sh. Help
Answer:	Sinks have aerators to slow down the water where a tub doesn't. It sounds like one possibility is that your exceeding the GPM for this heater. Next possibility, double check an measure your actually getting at least 240v at the heater, I had an issue where my unit was only getting 235v an it was causing a similar issue where only one of the two heating elements was activating. I had it set to 125F but it was coming out 100F. It was warm and without a meter I would of thought it was working correctly until I tried filling a tub. It couldn't even get the water warm. I pulled my wires out an restripped an cut an screwed them in an it fixed my problem, now its measuring around 245v. Make sure there is no copper showing after screwing down your input wires. Now filling the tub I noticed after about 10-15 seconds the water gets too hot to touch. I set it to 135F.
Question:	Do these tankless water heaters require an overflow line to the outside of the home or a pan like is required on normal water heaters
Answer:	No tank, so, no overflow line required. It mounts on the wall. A pan is needed if required by building code in your city.
Question:	what are the wiring and power requirements
Answer:	good morning,60 amp breaker and , number 6 cable !thank you have a great day!
Question:	How many amps are needed for rheem rtex - 13 240v heating tankless electric water heater

Product description

This Smart Technology electric tankless water heater is configured as a "whole home" model for climates where incoming water temperature is 67°F and above. This model is well suited for heating up to 2-Gallon per minute, which is the equivalent of one shower head (with a 1.5 gpm flow) and one sink with a low inlet water temperature of 67°F and an output setting of 105°F. Digital Temperature Control allows you to set your temperature in increments of 1 Degree. This model can also be used in colder climates as a Point of Use for a sink or other low flow application. All tankless water heaters are sized based on flow rate and temperature rise, and there is a direct relationship between the two. So if used in a cold area requiring a high temperature rise, it will be more limited in the amount of fixtures (gallons per minute) it can heat at one time compared to a warmer climate. When sized properly this water heater will provide endless hot water and only consume the energy needed, giving the user complete control. Prior to purchase and installation please verify this model is the right size for the expected demand and electrical requirements. The ECO 11 requires a minimum 125 amp electrical panel for installation with 60 amp double pole breaker connected to set of #6 awg wire. Plumbing connections are 1/2" compression fitting with the option of 1/2" NPT adapter included. For additional assistance please feel free to contact our support center at 877-474-6473.



NOTE : 11Kw at 220 is equal to 13kw at 240. .Activation Flow : 0.3 GPM

User questions & answers

Question:	Ours has only been in service for less than a year - will not adjust temperature to anything above 85 Deg. F. What do you think is the problem ? kds
Answer:	My only guess is that the rheostat (variable resistor) that the temperature adjustment knob is attached to may be faulty. If that isn't it then I don't know. Sorry.
Question:	The warrenty says that this unit must be installed by a licensed electrician and plumber, for them to honor the "life time warrenty." why
Answer:	Hello Bob, The reason is the same as why an innumerable number of gadgets around the world have that little "warranty void if removed" label. Because getting inside of one requires a certain level of training and expertise. Same with this unit. GadgetsGo is an authorized Ecosmart dealer. Kind regards,HenryGadgetsGo
Question:	My house is wired 110V. What additional items do I need to purchase for the conversion
Answer:	Just to expand slightly on prior answers, normally a residential service feed is 240 volts between the two incoming hot legs. There is also a neutral leg, which (hopefully) has zero potential with reference to ground. The voltage between either one of the hot legs and the neutral leg is 120 volts. The 120 volt circuits in your house are connected to one or the other of the two hot legs, and only one. An attempt is made to assign circuits to the two hot legs in a way that will roughly balance the load between them. The other side of a 120 volt circuit is connected to the neutral leg. There is additionally a safety ground run with the circuit, which also ties into the panel. Certain devices require more power (work product of current and voltage) than is practical to deliver using a 120 volt circuit. Common examples are your clothes dryer, and your electric stove. These devices are powered by both hot legs, with a difference in potential of 240 volts. This water heater is also such a device.STRONG BUT FRIENDLY WARNING: If you did not already know this, please don't make wiring this water heater your learning opportunity with electricity. Hire someone who knows how to do it right. Cutting corners, especially with higher currents and voltages, can lead to equipment damage, fire, and electrocution. Electricity is not magic, and you can certainly learn how to do many common wiring tasks safely on your own, but today is not the day to begin that journey. You need properly sized components, properly installed, and connected to an adequate service. Also, if you really, really foul up, you could conceivably wind up making that morning shower more energizing than you ever imagined, if you get what I mean. So newly aspiring electricians should go fix their grandmother's favorite table lamp instead. Once they have that working they can use it to to start reading books about electricity, residential wiring, and eventually, books about this stuff: http://amazon.com/s/ref=nb_sb_ss_c_0_8?url=search-alias%3Dstripbooks&field-keywords=nec+code&sprefix=nec+code%2Caps%2C164 . Of course, you still have to know not to nick conductors when you strip them, and other trade craft like that ; ) . Like almost everything in life that is fun, electricity will hurt you. Sort of like all those people you dated for a while, and then wished later you had never met.
Question:	what amp breaker is required
Answer:	The National Electrical Code requires conductors and overcurrent protection to be sized at 100% of the manufacturer's branch circuit recommendation for tankless electric water heaters. A 60 amp breaker is the same price as a 40 or 50, it is the wire that costs more. #6 AWG wire is required for a 60 amp circuit. If you undersize the wire it could overheat and catch fire. Protect your family and follow the manufacturer's sizing for this, or any other, electrical device. Your family's lives are worth the extra money. 

3 Smart Steps for Endless Hot Water

Step 1: Determining your average inlet water temperature is important, this allows you to determine how well your unit will perform in your desired location. A lower inlet water temperature will require a higher kilowatt product.

Step 2: Next you will determine how many applications your unit can run simultaneously at your chosen location inlet water temperature. Tankless electric water heaters are sized for maximum simultaneous use, not maximum fixtures in your home.

Step 3: Determining specifications and electrical infrastructure is important because without the correct infrastructure your unit may not fit into your breaker panel.

Question:	Richmond is manufactured by Rheem. Will this fit a Richmond 6e
Answer:	All these parts were identical to the parts I removed from my twelve year old GE water heater (further research indicated it was actually a Rheem). I swapped out the old parts and replaced them with these parts. The water heater now works as if new. I might note that these heating elements also look identical to similar generic items at Home Depot. I doubt they would stock it unless it fit just about everything.

User questions & answers

Question:	Can this directly replace a 40 gal tank heater with a 30A double pole breaker? What are power requrements
Answer:	No it can't. RTEX-24 requires 3 sets of wire and ground, and it needs 3x 40amp breaker. That's a total of 120amps
Question:	Can you use the 10/3 for one of the cicuits
Answer:	No. It requires three legs of 8-2.
Question:	Can the unit operate as a rtex-18 if i only hook up 2 of the elements? because i only need the 18 specs as of now but would like the option to upgrade
Answer:	Actually you can do this but you must be careful on which circuits are connected. Rheem says the elements are activated from right to left as power is required. The right most element connection also provides power to the control so this must always be connected. If the very left element is left disconnected, you will only get 2/3 of the rated power on a 3 element unit.
Question:	Why are 2 answers for the breaker requirements. Is it 3 double 40 or 3 double 60 amp
Answer:	If the unit draws 40 amp. you need a 2 pole 40 amp breaker 2 #8 wires good for 40 amp and 1 # 10 wire for a bond. Now if the unit draws 60 amps you need 2 # 6's good for 65 amps. A 2 pole 60 amp breaker and 1 # 8 for a bond( ground wire).

Product features

Simple, Reliable Hot Water Right at the Sink: DHC

DHC can deliver warm or hot water to a single point-of-use, usually a hand wash or utility sink. Please view the Sizing Guide images above in the image detail view for more information.

The heating element is controlled by a flow switch which means a DHC can never dry-fire and fail prematurely. And since all DHCs are hydraulically controlled, operation is quiet. DHC water heaters are equipped with a safety high-limit with manual reset. The rugged all copper design ensures many years of reliable service.

The simplicity and reliability of the Stiebel Eltron DHC tankless water heaters make them ideal point-of-use water heaters for these residential applications:

• Bathroom Sinks
• Kitchen Sinks
• Utility Sinks
• Laundry Areas
• Boats / RVs

And they are ideal for restrooms or kitchenettes in these office or commercial / industrial settings:

• Office Buildings
• Gas Stations
• Stores
• Schools
• Malls
• Hotels / Motels
• Warehouses
• Commercial Condominiums
• Restaurants
• Manufacturing Facilities

Electronic Accuracy: DHC-E

DHC-E can deliver hot water to a single sink, multiple sinks, or in certain conditions, low-flow showerheads. Please view the Sizing Guide images above in the image detail view for more information.

Control temperature simply by setting a dial

Set the temperature knob on the front cover, and enjoy water between 86–140 °F (30–60 °C). Change the desired temperature at any time. Advanced microprocessor technology ensures that the water temperature doesn't deviate from the set point even if flow varies.

Sleek Design & Constant Temperature Output

DHC-E models have our exclusive Electronic Temperature Control. Stiebel Eltron Electronic Temperature Control compensates for fluctuations in the flow rate and the incoming water temperature to maintain a constant water temperature output. Our smart microprocessor technology continually monitors info from the flow sensor & two temperature sensors & micro-adjusts the heating elements, saving power.
