13 best house tankless 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:	Can the temperature output be adjusted to 105F
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:	Can I use the Rinnai V65EP in Denver, Co? Temperatures during the winter can get below zero

Question:	Can the flow rate be adjusted up from 0.5gpm to say 1gpm or 1.5gpm (understood that the output water will be corresponding less hotter)? thanks in adv
Answer:	This is a 199,000 btu model, a 3/4" gas line is required to have sufficient gas supply.
Question:	degree water going in what degree will be at the tap
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:	Would you recommend this model for a shower in a guest bathroom
Answer:	IT CAME WITH ADAPTERS ON THE TOP. NO PIPING.

Product description

The 3M Aqua-Pure Whole House Scale Inhibition Inline Water System AP430SS is designed to help reduce scale build-up and corrosion - thereby helping to extend the life on hot water-using appliances such as water heaters (standard (gas or electric) and tank-less), boilers, clothes washers and dishwashing machines, and on plumbing fixtures like faucets, pipes, and shower heads. The AP430SS provides a flow of up to 10 GPM with ¾” NPT inlet/outlet connections. Scale is calcium and magnesium deposits that often form when hard water is heated. Water hardness is responsible for most scale formation in pipes, water heaters, finishes and flat surfaces, and other water using appliances. Over time scale build-up can significantly shorten the life of any water-using appliance. Also scale buildup inside pipes causes loss of water pressure as the interior gets smaller and smaller over time. The AP430SS contains polyphosphates to bind calcium and magnesium hardness minerals, helping to prevent them from precipitating out (or becoming a solid) and building up on metallic surfaces. Polyphosphates also helps prevent corrosion by forming a thin protective layer on the metal surface. The 3M Scale Inhibition Water System AP430SS is tested by NSF International to NSF/ANSI Std. 42 for material and structural requirements only. The overall single vessel/cartridge design of the AP430SS makes the 3M Aqua-Pure AP431 Water Filter Cartridge change-out easy for professionals as well as end users. Change disposable filter cartridge every 6 months or sooner if you observe noticeable reduction in water flow rate. The AP430SS is to be installed on the cold water supply line of the water heater or at point-of-entry of water into the home. Tools and parts required (not included): one ¾” stop and waste valve (compression type), PTFE tape, two ¾” male x ¾” street adapters, one ¾” compression gate valve, and pipe cutter. Read all instructions carefully before attempting to start installation. The existing shut-off valve remains in place and still acts as the cold water shut-off. This filter system has 3/4” connections. The AP430SS can be adapted to various pipe sizes by using reducing adapter on either end. Installation fittings can be sweated or threaded. Use galvanized fittings for installation of galvanized pipe. Aquapure by Cuno hot water system protector to reduce scale build up in pipes and extend life of water heater. Installs on cold water side of hot water system to inhibit scaling and corrosion.

User questions & answers

Question:	Just received. It appears a lot of water bypasses the filter, can someone confirm this is not the case? Mine is just like customer uploaded photo
Answer:	Not a filter, a water treatment cartridge. Rated at 10gpm by the manufacture, a small amount of the water flow is diverted down into the cartridge through a single hole in the elevated tab, in the center of the tee. The polyphosate is slowly dissolved and a small amount of treated water flows back up and out 3 small holes around the elevated tab. According to the manufacture it only takes 2-3 parts per million to treat for scale. A little bit will do ya.
Question:	Does this help with water spots on glasses and scaling on bathroom fixtures
Answer:	We have a lot of calcium in our well water. The heat from the hot water tank is what causes the minerals to form scale. We placed this on the cold water side of the hot water tank and noticed a big improvement in water quality, especially on shower doors and dish washer. I have changed it twice now. The first time at 3 mos because the info says it can clean up existing scale in pipes and fixtures. The bottom line is if your water is very hard that will affect how much benefit you get from this product. So will you be happy with a 50% improvement in quality? I know I am cleaning faucet screens a lot less. Still have a jug of vinegar around though! Hope this helps.
Question:	GPM seems to low. I have 2 Tankless units, EACH one does 9 GPM
Answer:	we have an electric tank less that is rated at 4.5 GPM. We have very hard water in this part of MA and also have a well. We have been in this house for 30 years and have had problems with pipes rotting away. When we installed the electric tank less we installed this filter also. We used the heater for a few months and than had the plumber perform the maintenance suggested by the tank less mfg. It was clean as a whistle. Our flow rate is not as high as yours but if you had one in line with each heater - i would think it would work fine. Our heater used 120A for 4.5 GPM - if yours is electric it most use a lot of power! For our use I am very satisfied with the filter and given our water quality situation and how clean the heater was - i would highly recommend this filter.KR in MA
Question:	Can this system be installed with the filter in the horizontal position (copper pipe is running vertically
Answer:	In my opinion, if this is collecting any particles before getting into Tankless water heater, the particle should fall in vertical direction so filter should be installed in vertical direction. I installed my filter in vertical direction before cold water is getting in to the tankless. In order to get a right answer, it would be the manufacture because they are the one who designs the filter.

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.

User questions & answers

Question:	What is the recovery time if the 7 gallons of hot water is used
Answer:	I have the 4 gallon tank and it is not too bad for the reheat
Question:	Can I reduce the pipe's size from 3/4 in to 1/2 in without any negative effect on the unit
Answer:	No harm to unit.....Max water flow will be reduced a little.
Question:	Can i use this to replace a small rv hot water heater
Answer:	Yes, but realize that it's electric and draws quite a few amps, most rv water heaters are propane.
Question:	The Manual request for the ES8 a 20 Amp breaker and 12GA wire. The wattage however is 1440 with 12 Amps. Why then 20 Amp breaker and not
Answer:	I would use a 20 amp circuit with 12 ga wire but there are no inrush concerns with a resistive load. A heating element does not have a higher initial current draw like a motor. It draws 1440 watts or 12 amps at 120v. Since 14 ga wire must be fused for 15 amps, this device by itself is already at 80% of the circuit’s capacity.

Great for Small Spaces

Water heaters are compact and lightweight and can be floor, shelf, or wall mounted (except 7 Gallon) - features a sleek and attractive design to blend seamlessly with decor.

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.

User questions & answers

Question:	service number
Answer:	785-477-8702
Question:	How much current does it draw
Answer:	Hello Donna. Thank you for your question. This unit uses 120v, 60Hz and draws 2 amps.If we've helped you, please prefer us when you purchase on Amazon. Kind Regards,RossGadgetsGo
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.

User questions & answers

Question:	which models are "condensing" units, please
Answer:	I don’t know. But I suggest u look for a different brand. It already failed twice in less than a year and their warranty is a scam. They provide the parts which are pennies and leave out labor.
Question:	How does it effect the water pressure, will it change
Answer:	It does not effect my water pressure at all. I’ve had it for over a year now
Question:	My existing water heater is located next to and shares a flue with the furnace. Can I hook the same way on this
Answer:	Hold up there, previous answer, not so fast. It is true that you should not have both the hot water heater and furnace venting directly into the flue, combining the exhaust. However, some people see their vent pipes entering the flue (or chimney wall) and assume they are both releasing the fumes inside the chimney. In some cases, the venting pipes continue separately up the flue. Joseph, if you have two vent pipes entering your flue, there is a chance that both pipes continue separately up the flue and out the top. If that is the case, you may be able to use the existing hot water vent system. When you look at the top of your chimney, do you see two terminations coming out?
Question:	How does very cold intake water affect performance
Answer:	Sorry to contradict but the temperature of the water going into the water heater will definitely have an effect on the temperature of the water coming out. the water heater needs to provide enough BTUs to heat the volume of water that you need to the water temperature that you want. If the water starts off at a lower temperature it will take more BTUs to get it to the temperature you want. This unit claims to be able to provide 6.6 gallons of hot water per minute but that assumes the water is startling an average temperature. If you have a modern shower head it will only use about 2.5 GPM but if you have second shower going, a hot water faucet open or a clothes washer filling at the same time you will run out of capacity quickly. Rinnai should have tables on their website that shows the ability of the unit to heat water at a variety of starting temperatures to a range of hot water temperatures at a given flow rate.
