Leaks…The water connections are tough to connect properly if your not a pro. Long story short the best way after talking to a few plumbers is use 1/2 copper pipe. Use the 2 brass nuts with the crush ferrules they are 1/2 inch and fit a 1/2 inch copper pipe perfectly.If you look at the water connectors closely you can see there’s a beveled edge on the inside rim. if you see a beveled edge on any water pipe that’s designed to use a compression connector. The compression nuts that come with the unit work good.Best to use a short length of 1/2 inch copper on the cold input then use a 1/2 cvps sharkbite to connect to pex or cvps or copper. If your house uses white pvc sched 40 sharkbite makes a cvps mustard color on one side of the sharkbite and a white sched 40 on the other.The output hot side its best to run a short 5 inch stub then sweat an 90 degree elbow on then run another length of copper to a 1/2 sharkbite connector. Use a longer copper length because that output pipe gets really freaking hot. Do not use washing machine flex those are not for really freaking hot lol water and they will leak anyway. The whole thing is a pain in the ass.The other must have is a real good water filter for you house main. No tankless water heater will be happy with unfiltered water. You would be shocked to see how much rust is coming into your house from the street. You cant just fill up a glass of water and look at it to see how clean your water is it does not work that way you must use a good filter then 90 days later look at how much rust it captures. I have a 10 inch dual big blue filter system on my house first stage is sediment and second stage is charcoal. I installed a big Ecosmart tankless about 10 years ago and have not had one issue with it.I change my filters every 90 days lots of rust in my town. The picture is the sediment filter after 90 days.Yours may be even worse. But you can’t lose with a good filter system your faucets and pipes wont rust.

WorksIt was pretty easy to install. Both input and output leaked, but that was on me and my plumbing skills. I got it to stop leaking. Electrical was straight forward. No problems except the lights in the kitchen would flicker and dim when i turned on the hot water. That was easily fixed by replacing the dimmable leds with regular incandescent bulbs. The dimmable LEDs are sensitive to the voltage drop when the heater turned on. The water is very hot. Flow seems just a bit lower. But still way better then an old school stinking and rusting bladder type heater

Excellent product however, there were missing partsThese things are great. I installed the exact same model 10 years ago for my entire house and it worked great even with two showers running at the same time. I am glad I got 10 years out of it since nothing is built to last anymore but I was a little dissapointed that there were parts missing during the installation. The wire bracket which holds the wire tight in the unit was not there and part of the wire inlet grommet was missing. My original one came with a 2 foot section of wire that was pre-wired into the unit. The one I just received did not come with any wires. I am not sure if it was supposed to or not but fortunately I had my old one to take the missing parts from. If this was a brand new installation I would have been much more upset about it. Other than that, the unit itself out performs any of the other units I have seen that also run off of a single 60 amp breaker and it is very small. The temperature can be turned up to 140 however I have always keep the dial around 112 and that seems to be the perfect spot. Hopefully this helps someone.
Very easy to intallThis unit is located in my basement. I purchased it to replace a blown out 50 gallon hot water tank that only lasted 6 years. it is a 13KW unit that heats all of my hot water spigots thru out my house with no issues at all.6-2 wire is required to attach it to the 60 amp breaker. Don’t assume that you can use the same wiring that you used for the hot water tank.

Buen calefon para una ducha en ambientes no tan frias…Contento con mi compra hasta ahora. Regula bien la temperatura. Funciona sin problemas hasta ahora (3 meses) . Lo utilizo en Ecuador en un ambiente de temperatura entre 14 a 20ºC pero no lo tengo puesto a su maximo de calentamiento, porque no es necesario para tener una ducha caliente.
Excelente opción, pero no es para todos.Funciona perfectamente, el agua caliente comienza a salir en menos de 1 minuto.En casa la distancia entre el calentador y la regadera mas lejana, está a aproximadamente 15 metros. Al abrir la llave de la regadera, en aproximadamente 1 minuto comienza a salir agua caliente. Una vez alcanzada la temperatura, se mantiene totalmente estable. Es sorprendente que un aparato de estas dimensiones proporcione tanta agua caliente en tan poco tiempo, y con tan buen flujo, pues la regadera que menciono es tipo ducha, no es una regadera “ahorradora”, y caliente perfectamente.Ahora bien, todo esta maravilla viene con un precio, y es el consumo eléctrico.Lo tengo configurado a 35ºC y puedo medir el consumo energético de toda mi red eléctrica. Un baño de 15 minutos consume aproximadamente 1.5 KWh. Si consideras que en México, una casa promedio consume entre 5 y 7 KWh diarios, el consumo de éste calentador es enorme. Estos datos son para finales de febrero, en Guadalajara, Jalisco, en donde la temperatura del agua que se recibe del SIAPA es de alrededor de 20ºC. En tiempos mas fríos el gasto energético consumirá mucho más, en tiempos más cálidos bajará el consumo eléctrico.Necesitas considerar cuidadosamente si esto es una opción para ti, puesto que, dicho en pocas palabras, instalar este calentador en una casa o departamento implica casi en automático pasar a la tarifa DAC (Doméstica de Alto Consumo) de C.F.E. (Estoy en México). De manera que la decisión de compra debe ser respaldad contra lo que actualmente consumes de electricidad.Como guía muy básica te puedo comentar que si tu familia es de 4 integrantes, y usas agua caliente esporádicamente para lavavajillas, lavadora, etc, este calentador fácilmente te consumirá entre 8 y 9 KWh diarios.Yo tengo paneles fotovoltaicos, calculados precisamente para este tipo de consumos, de manera que este calentador es solar, indirectamente, pero solar, sin embargo, instalar un calentador solar de agua propiamente (de esos de tubos de vidrio al vacío) es mucho, muchísimo más económico.Otra cosa a considerar: Necesitas una instalación eléctrica a 220V. y en tu centro de carga requires un breaker de 60 Amperes. Considerando que en muchas casas, el breaker principal de la casa no pasa de 50 Amperes, necesitarás considerar que es probable que necesites actualizar tu centro de carga, tu breaker principal, en resumen… NO es para cualquier casa.Ahora bien, la tecnología que ofrece este calentador, la automodulación es realmente efectiva, no veo bajones repentinos de la intensidad de la luz mientras está en uso, pero definitivamente, el consumo eléctrico es enorme, fácilmente se va a los 50 Amperes en los primeros 30 segundos para lograr calentar el agua rápidamente, una vez que alcanza la temperatura, tiende a bajar el consumo un poco, pero siendo de paso, mientras tengas la llave abierta, el calentador sigue activo, lo cual, por un lado te da agua caliente interminable, por otro lado, en 1 hora de uso fácilmente puedes consumir hasta 13 KWh.Como verás, decidirte por este calentador depende de un cuidadoso análisis, solo es adecuado para situaciones MUY particulares.
Outstanding!!!I read some positive and not so positive reviews. After using this 11kw unit for more than a few months it is nothing short of outstanding. I replaced my gas hot water tank with this unit when the gas valve about to cost me $450 for a new one. Please read the tips I have provided below from what I have experienced.First off, you need to get your hot water usage under control. Hot water is not required for your laundry anymore and for sinks your water just needs to be warm so your hands don’t get cold when running hot water. Your dishwasher has a heater to heat the water. I use the “Sanitize” option on my dishwasher so don’t worry about the incoming temperature of the water. For my shower I purchased a 0.625 GPM (2.2 LPM) shower head that is meant for RV but I honestly find it to be more than enough. Your mileage may vary since people are as insane about their shower as they are about their coffee. I also have a 1.2 GPM (4.5 LPM) rain shower head in the second bathroom which also works well. For the 11kw model this flow is as much as it can handle. You cannot run two showers at a time but I couldn’t do that with my gas hot water tank without being severely pissed. I used a ball valve to adjust the incoming flow to a point where when the sink is full on the unit still keeps up. I set the temperature to 103 degrees F and find this temperature to be perfect for the shower at full hot so you are not heating up water that needs to be cooled at the shower. At this temperature and flow the unit draws about 32Amps at 240V but you’ll need to provide a 60A breaker with #6AWG wireI live east of Toronto so incoming water temperature is very cold in the winter. This unit has no problem keeping up to that. If you have a 200Amp service I would recommend the 18kw unit. I have a 100amp service and this is great. I’m putting in a basement apt and plan to use a second 11kw unit for the basement with a second 100amp service.I estimate this unit to cost me about $2 a month for the electricity to run it. With low flow shower heads I don’t have to run the exhaust fans anymore when showering which saves even more.Overall I am very happy with with purchase. It fits in a little corner of the basement and frees up the space my tank was in.

Works well and simple to use!Ecosmart 11 works well in Nanaimo, Canada. Our water can get down to 2 C! A must is a water restrictor in the winter!!! 2 gpm is warm… 1.75 nice temp… 1.5 or less hot! and less then 1 gpm really hot!!! Important to have plumber rap 6-10 coats of Teflon tape around water line connections directly on unit; the threading on the bras fitting is milled too much… Space saved is great!!! I’m saving at least $0.20 a day on heating water I don’t use. 365 X $0.20 = $73 of wasted heat! Recommend getting larger unit in cold climate. Install cost are going to be expensive… Better to just in stall low flow shower heads etc… I like mine!Up date: February 2020 I just installed 1 gpm shower head restrictor and they work awesome with the Moen shower wand that was 2 gpm. My thermal imaging camera showed 5C water jumped to 49C at shower head!!! I’m down to $0.12 per ten minute shower now and don’t notice a huge difference in water reduction…

So far I am very happy with this unitMy old gas water tank died on a Friday morning on a hot summer day. To replace it with the same thing would have cost probably > $1000 after factoring in the labour cost for the gas and water connection and I did not have budgeted for that kind of expense.So I decided to go the DIY route and got this unit shipped at the door next day.Went to homedepot and bought 30ft of #6 wire which was rated for 60amps as required. That was about $25.Flexible hose connectors for pex tubing – one of them with a shut off valve cost another $45.60 amp breaker for my federal pacific panel was another $62.240V plug and outlet another $25.Teflon tape for the brass connectors $0.70.After installing it and running the first tests found out that the wire was getting hot not just warm.Realized the wire I bought was aluminum and connections were getting burning hot not just hot. After further research I found that connecting aluminum with copper is a no no so went back to hd and got copper wire this time which was about $120 for 30ft.So all in the whole thing cost me close to $700 after several trips to the local hd.Now I know how to install a breaker in the electrical panel, connect pex tubes and learned a bit about high amps electrical wires. Youtube is your friend.After one week of running the unit I realized that my thermostatic water valve in the shower is not playing well with the flow sensor in the unit but it’s possible to have a hot shower if I reduce the water flow on the shower to low which is ok. I have the heater adjusted to the max temp which is 60 Celsius. On the kitchen sink the water comes out burning hot. I am in the PNW area and the cold water supply gains about 5 degrees over winter temperature.So far I am very happy with this unit.
Wish the thing actually worked.Worked great for about 2-3weeks. Then it started making a humming noise the manual said could be expected. Then it stopped entirely. We are a 3 heated water faucet household with only 2 people. No dishwashers, no laundry machines just two sinks and a bathtub in our little cottage. The demands placed on this were not unreasonable.The initial contact with the repair technician was helpful and polite, she send me the wires for the temperature regulator and suggested I disconnect the old wires to see if that would work. No children in this house, so it seems safe enough. The heaters continued producing water for approximately 12 hours. Then ice cold. After waiting another 3 weeks for the part to be delivered I installed the new wires and still it didn’t work. I was instructed to use a voltammeter to check the heater. These aren’t your typical house owner requests and I’m fortunate to have an electrician for a neighbour or I would have to be paying a professional their asking wage to accomplish this. They wanted Oms and Voltage. I acquired both and hooked up the old water tank in the meantime to ensure we still had hot water. Upon calling to report my findings the next technician requested I obtain another reading with the water running again. I informed her I had already acquired the reading prior to calling. She then asked if I had performed “Routine maintenance.” When I inquired what the routine maintenance is on a only now 6 week old unit. She dropped that topic. Everything about this feels like a goose chase, I asked about the possibility of this being a lemon unit and the possibility of a replacement as I do actually want the tankless system, not the monster hot water tank. Her response was only if I had filled out the warranty registration online and reconnected the water lines. This is now twice I’ve had to empty and then move the hot water tank just to try to get this unit running. A month of waiting for parts and when I followed the original instructions For obtaining the voltage readings BEFORE disconnecting the hot water tank I was told to do it again and ensure I had registered the product online as they didn’t receive the paper warranty registration. Should’ve bought locally so I could return this, but Amazon only gave me 3 days after delivery for a return window. Very disappointing overall.
