Questions & Answers

I have 200 amp service. Is it big enough for the 27 kw

Asked by: Butch
None of the above answers are correct. To determine if this unit can be installed on any size electrical service, an electrical load calculation needs to be done. In the USA the methods for determining the total loads are based on the adopted codes in your area (NEC/IRC/UBC). Many professionals are capable of completing a electrical load calculation correctly, but not all, so buyer be ware. This unit would also generally require a building permit in most municipalities. This unit can easily exceed the capacity of your electrical panel.

27 kW Self-Modulating 5.3 GPM Electric Tankless Water Heater is rated 4.0 out of 5 by 190.
Rated 5 out of 5 by from Love it, love it, love it! I have a Jacuzzi tub that fills faster than 5 GPM (plus 3 showers + a ... Love it, love it, love it! I have a Jacuzzi tub that fills faster than 5 GPM (plus 3 showers + a washing machine + a dish washer, etc.) so I've put two of these units in series (see photo), setting the first to 126 degrees and the second to 124 degrees so that the second is activated only when needed (quite rarely). For the first time since we've lived in our house, our kids and guests can shower or bathe in hot water ever after we've filled our Jacuzzi tub. Fabulous!!! Did I mention that this product has a lifetime warranty and has a super-small footprint. I've been replacing my way-too-big (80 gal), way-too-energy-hungry water heater every 8-12 years like clockwork (rather expensive). Now I think we're set for life!

However, the brand I had before was nowhere NEAR as well-made as this. During the 20 years I used that brand, I had to replace it FOUR times due to leaks. And, I had to replace the motherboard twice to to component failure. The Eco27 is simplicity itself. Not convoluted motherboards with a ton of components to burn out. The chambers are COPPER unlike the former brand I had which were plastic or resin. I did a LOT of research before I chose the Eco27. After I installed it (which was a piece of cake following the instructions), I was rather surprised to find how quickly it heated the water. My old unit had four elements and it didn't heat the water as fast as the Eco27 with three. These guys did it RIGHT. Be sure to use their sizing guide to determine which Ecosmart is right for you.

Warranty registration requires you name the licensed professional who installed it, including their license number and contact information. So in my case, I was simply replacing a unit that was previously professionally installed, including the needed 3, double breaker, 40 amp 240V circuits, so just a matter of turning off the breakers, unscrewing the plumbing and reversing the process with the new unit. Works well and I like the unit, but it peeves me that I bought it at a do-it-yourself store, did it my self with perfect execution, but if it fails tomorrow, I'm apparently out the $505 -- unless I can diagnose the part and replace it myself, but I should be able to get it warranteed. Hey Home Depot, should you be selling appliances off the shelf which provide no warranty to a competent do-it-youselfer? If I buy a washer and dryer (electric), install the needed 240V wiring and connect the plumbing, would the pair be warranteed? I think so. So, what's with these Ecosmart folks?

We have a family of 4 that likes to take long hot showers. With our old 50gal after the 2nd or third shower water was cold not now. We live in northern Ohio so in the cold months it delvers the hottest showers if no other hot water is run at the same time. And if you run your bath water the slower you run the water the hotter it will be. And we save on our electricity bill as it does not have to keep water heating in the tank when we are not home, I self installed this unit myself using sharkbite connectors off the shelf . Did have to add 3 ( 40amp )breakers to my breaker box. There are good videos on youtube on Installation

First off I live in Savannah, GA needless to say my ground water temp is probably mid 60's. At its coldest. I installed this unit myself in a day to include all Plumbing and electrical work. I did have to run new electrical 3 runs of 8/2 Romex, and 3ea. 40A dbl pole breakers. I'm extremely handy with home renovation work. Plumbing took about 10 minutes total as I located my new Tankless unit on a sub panel close to the old 50gal tank. I also used the SharkBite Tankless water heater installation valve kit to connect my 3/4" PEX water lines. My system has been installed and running flawlessly for about a week. There are 2 adults and 3 teenagers in my home and we haven't had our usual evening hot water issues at all. We do have to slow the flow down when filling our garden tubs but common sense ( and the directions ) tell you the unit cannot keep up running full bore on a 3/4 inch water supply at 55 PSI the water doesn't make contact with the heating elements long enough to properly heat. However, with the faucet 3/4 open the water is exactly at the 125°F that I set the EcoSmart27 to. Showers are awesome endless hot water so far we have ran 2 showers and several sinks at the same time with no noticeable loss of hot water. Yes, all sinks and showers have the factory water saver devices installed. I couldn't be happier with this unit. I have recommended this unit to all of my friends and family. On a side note If I had Natural Gas in my home I would have installed a Gas Tankless unit. The installation would have been a little simpler.

Normally I do not provide feedback on products unless it is really bad or excellent. In this instance this product is ABSOLUTELY WORTHLESS. Called and spoke to a couple of different tech support folks at Ecosmart to make sure I was getting the proper size unit and still no good. Not sure how the Ecosmart did their testing to come up with their advertising figures, but in the real world there is NO WAY THIS UNIT CAN HANDLE ANYTHING MORE THAN A SINGLE SHOWER AT BEST IF YOU WANT HOT WATER OVER 105 DEGREES and that is with a flow rate of probably 1 GPM. Their advertising info. is so far from the mark, that it is a flat out lie and false advertising. Bottom line, this is maybe good for a studio apartment with one shower. If you want the full details read below. Total time spent (wasted) installing unit and trouble shooting about 16 hours over 4 days, not including time spent going to HD for parts. The ecosmart 27 model states 5.3 GPM, however, could not even get 2 GPM if you want hot water. The description states "The ECO 27 is one of the most powerful models from our full line of tankless water heaters, with the capacity to handle a large single-family home and is perfect for a large Roman-style and Jacuzzi tub or high demand of hot water between multiple applications, even in colder climates". http://www.ecosmartus.com/products/electric-tankless/eco-27/#product-tab1 1. Location is Northern NJ (a green zone on their sizing map) and according to the map it should handle two showers and sink at the same time with the inlet temp being 52 degrees and an output at 105 degrees based on their website at http://www.ecosmartus.com/products/electric-tankless/eco-27/#product-tab3 2. Home has 4 full baths (one with jacuzzi tub) and a 1/2 bath. Wanted to be able to run two devices at same time at the minimum. (kitchen sink & shower or Laundry and Kitchen sink, or two showers) Wanted to originally get the 36 model, but did not as I would had to upgraded the electrical supply coming into the house to 300amps (cost about $2,000) which I considered seriously but based on conversation with the tech support, went with the 27 as they said it would at the minimum handle two showers at once. Ran the required electric three dbl pole circuits with ground using 8 AWG wire and connected to the unit (spent ~ $600 in materials). Set the temp to 120 degrees and opened the hot water on sink closest to the unit. After waiting about 5 minutes or so water would not get hot, so I raised the temp to max of 140 degrees. Still no hot water (luke warm at best) Called tech support and checked to make sure that the proper AMPS (234 AMPS), heating elements, thermostats, and everything else was in good working condition but no hot water. One of service tech said, that the flow was to much and that I should use a flow reducer and suggested using a ball valve to decrease the flow rate on the outlet port on the unit. Re-plumbed the unit and installed ball valve and slowed the flow (volume of water) the temp did go up, however could only use one sink or shower at a time. When trying to use sink and shower water flow was diminished to a point that it is about 1/4 of the normal flow rate and really not good for showering. According to the map even in the blue zone with an inlet temp of 37 degrees, the unit should be able to run 2 sinks and a shower at 105 degrees with 2,7 GPM. There is no way this is possible, as I had to almost completely shut off the ball valve to get hot water guessing flow was reduced to ~ 1GPM to reach ~105 degrees. The water in the shower basically had no pressure but at least warm / hot. Then my wife tried to take a bath (jacuzzi tub) with nothing else and the water flow was a trickle and could not fill the tub (the water in the tub turned cold even though it was only filled up about a 1/8th of the way) Do not buy this product.... Had it for about two weeks. It does not meet my expectations.

Rated 4 out of 5 by from My mother purchased a walk-in tub and just as I predicted, her 40 gallon traditional water heater... My mother purchased a walk-in tub and just as I predicted, her 40 gallon traditional water heater would not keep up. I decided to install the Ecosmart 27kW unit. There are 3 things you need to consider BEFORE you purchase any electric tankless water heater: 1. Do you have enough electrical service? You likely have 200 amp service and a 220v electric water heater now meaning you are using 2 slots already. Do you even have 4 more empty slots? This thing takes 3-40amp breakers. If you have 100amp service - stop looking here. You can work around if you don't have enough open slots but you will have to install another panel - $$$. 2. Water inlet temperature. For most people, you are on city water meaning your water temps are not going to fluctuate much during the year. For well users, it might fluctuate meaning it will affect the performance. 3. Water flow rate. Electric tankless water heaters are misunderstood and you will see some negative reviews. Most of these I would say, they don't understand how they work. They all work the same. You take cold water and run it through a heat exchanger to generate hot water. If the flow rate exceeds the ability of the unit, it will not keep up and you won't be satisfied. To compensate for this, you can slow down flow so that it does not overrun the unit. All you have to do partially valve off the supply side. Turn on your hot water wide open on a faucet that is not restricted - likely the tub spout. If your tankless hot water heater is not keeping up, partially valve off the supply side until it does. You will find that fine line. Leave it set when you find that correct flow rate. Faucets with restricted flow (shower heads, sink faucets, etc) will never see any difference. Some higher priced unit automatically do this. I hope this helps because these do work but only if you understand them. Buy a bigger model than they recommend - flow rate if the key. 5.3gpm is not much with 3/4 cpvc from a water tower.
