13 best demand electric hot 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.

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. 

User questions & answers

Question:	Is it necessary to connect an expansion tank to this heater (for safety purposes)? It states something to that effect in the user manual
Answer:	The expansion tank for this heater is not required. Most people already have these installed in their homes but if not then it would be Ok without it as there is a pressure relief valve on top if something happened. GlobalTowne is an authorized Bosch distributor.
Question:	would this be able to supply a shower
Answer:	A standard flow shower head is around 2.5 gallons per minute. A low flow head is around 1.5 gallons per minute. The recovery rate for a 90 degree temperature rise is 6.8 gallons per hour! So even the 7.5 gallon unit would only provide 4 minutes of shower time before the temp dropped off dramatically. (even at the low flow rate..)
Question:	Can be used "in-line with a large hot water source"? Would it help a large bathtub that runs out of hot water before it gets full from main tank
Answer:	If your bathtub is bigger than your main heater tank, this unit isn't going to do much for you. It will add 2.5, 4, or 7 gallons to the capacity of your main tank, depending on which Bosch unit you buy. The 7 gallon unit requires a specially wired circuit. You will also get a little bit of lukewarm water that was in the line between your main heater and the Bosch unit. Unless your main tank is awfully small and your bathtub massive, the 4 gallon unit should work for you. Maybe a demand type thankless heater in your bathtub hot water feed would be a better choice, but be careful to size it properly for your desired flow rate and temperature rise. Also a tankless is likely to require special wiring.
Question:	When this heater is connected to the hot water line, what happens with the cold water that was sitting in the pipes
Answer:	When the tap is opened, the hot water in the unit flows out. The colder water that was sitting upstream of the unit, enters the unit to be heated. If the tap remains open, the newly heated water flows out, being replaced eventually, (depending on the distance to the main water heater), with the water from the main water heater. You will probably set the unit temperature to equal the main water heater temperature, if you want to keep a constant temperature, but other scenarios are possible.

Minimize Wait Time for Hot Water

Waiting for hot water at a sink located far from a primary heating source can be frustrating. Only having access to cold water from a sink is just not useful, and plumbing a hot water line to every sink in a home or business requires time and money. To get hot water where it’s needed, when it’s needed, a better solution is to use the Tronic 3000 T from Bosch: a point-of-use electric mini-tank heater. This heater can supplement a primary water heating source, or be used under a single sink. In fact, the Bosch Tronic 3000 T can be used for three different applications: as a sole water heating source for a single sink, as a supplement to an existing heater located far from the sink, and as a buffer installed in-line with tankless water heaters that experience intermittent cold water, also known as 'cold water sandwiching'. No matter the configuration, there’s minimal stand-by loss from this premium mini-tank water heater.

Answer:	rinnai recommends the GTK03 Grundfos kit for this unit
Question:	are any of these tankless water heaters plug in
Answer:	I think, you need buy a WiFi module, call Rennai and ask. Circ-logic did not work for me, I had to install re circulation pipe. Because of the high minimum flow requirements, this unit did not work with any regular re circulation pump, so wasted money buying a Watts pump. And paid double for the labor. Rennai told me that I should have bought their thankless heater with re-circulation built in.

Question:	Can the temperature output be adjusted to 105F
Answer:	Most rinnai tankless weather it is out door or indoor, have a control board to adjust temp and either on or off
Question:	Can I use the Rinnai V65EP in Denver, Co? Temperatures during the winter can get below zero
Answer:	It can definately be out doors in freezing temps, tho power failure arent good for it while in a freeze, tho keep in mind it will use alot more energy for frost protection, indoor units are safer amd more efficient in this case
Question:	Does this unit come with controller? rinnai tech said i needed a mc-91-2us controller? do i need to buy separate
Answer:	I bought model V65EN. It came with a wired digital controller. The installer did not run the wire into the house and mount the controller indoors. He simply set the controller at 120 degrees and left the controller inside the unit. If I want to change the temp, I have to take the cover of the unit.
Question:	What does the "Low NOx Mean
Answer:	Good place to check for info like this is Wikipedia. Here is what they say: Energy efficiencieseditMore tangible cost savings are defined when comparing the energy efficiencies of gas heaters with low NOx emissions with conventional flued types. Gas heaters with emission problems are flued and inherently lose substantial energies in the form of hot flue gases to the atmosphere. In addition, the choice of placement of flued heaters is greatly impaired due to flue installation restrictions.In contrast, dedicated low emission gas heaters do not require a flue system. Furthermore, with the introduction of oxygen depletion sensors and thermostatic controls, they do not place critical reliance on ventilation as previously was the case. These heaters can be positioned more conveniently and centralised to affect optimum warm air distribution. By definition unflued low NOx gas heaters are 100% efficient as all heat energy released from the flame is converted to useful heat.Hope this helps. June

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.

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.

Question:	can i vent this thru a masonry chimney
Answer:	It needs to be ported outside.
Question:	What is the highest temperature achievable from this water heater? Will it produce temperatures in excess of 150 degrees F
Answer:	Assuming you have everything hooked up correctly, at 3.5 GPM, the MAX TEMP will be NO MORE THAN 55 degrees ABOVE THE TEMPERATURE OF THE INCOMING WATER. For example, if the incoming water temp is 50 degrees in the winter, then the max winter temp will be 105. In the summer, when the incoming water is 65 degrees, the max summer temp will be 120 degrees. This is the way ALL demand heaters work. Be SURE to check the TEMPERATURE RISE specification on ANY demand heater to know what it is truly capable of. If the TEMP RISE is specified at 3GPM, and you try to set it higher, it may CUT BACK THE FLOW RATE to achieve the higher temp, but it will NEVER exceed the TEMP RISE spec.
