Review: I was in the market for a new water heater and was debating on going tankless because since being in my home, I've had 2 water heaters (10 years apart) flood my bedroom and ruin my wood floors on one occassion and most recently flood the hallway and laundry closet where my water heater is located (thankfully tiled). I was more motivated to go tankless because I saw the price drop in the equipment since years ago when I first priced it out and if I had one more leak, I was going to scream (my water heater is located in the center of my house (not in the garage/basement like most). So I researched and the ECOSMART was getting great reviews and had the most competitive pricing. I had a 40 gal tank water heater and my plumber said I should be good with an 80amp tankless unit for my home (2 bathrooms equiped with 2 sinks and shower and bath, washing machine, dishwasher and kitchen sink and 3 people in the household and perhaps one day, 4). I orginally chose the 112.5amp unit because the price was lower than the 100 amp and I was nervous about the 75.5 amp unit not being enough because I read reviews that when operating what I had in the house, their wasn't enough hot water. When it came time to install-the plumbers job was easy and didn't cost a lot, but the electrician warned me that most homes are not orginally equipped with enough amperage to support all of the house and a whole house electric water heater. He also told me that the $50 savings I got with buying the unit with 112.5 amps was going to be squashed by the cost to supply power to it. He suggested that I spend the extra $50 to save hundreds of dollars on his end. So that I did and I don't regret it. When all was said and done, I don't regret getting the tankless regardless of paying way more than had I gone with tank. PROS: More space in my landry closet for storage and shelving and organizing (much desired and needed) I live in FL and my pipes are located in the attic, so my water does not take any longer to get hot than it did with the tank. Energy Efficient with on demand hot water Long long hot showers Aestheically pleasing to the eye NO MORE ANXIETY about floods in my home-I could install wood if I really wanted to now CONS: Electrian is going to cost you, especially more the further your water heater is away from your electrical box (more wire and I chose not to move it because the closer your water heater is to the devices it's supplying-the quicker you receive hot water) For ppl not in FL or warmer climates, I can see where it might take a bit longer to get hot water-but I don't see that as a deal breaker really.
Review: I have installed this EcoSmart 24KW heater as a solar water heater backup. I ran two 3/4" EMT conduits and used 3 pairs of #8 copper for the installation. The EMT serves as the safety ground. (A note here: I ran 3 wires through each conduit, and the wires actually vibrated at 60Hz due to magnetic forces while on. I had to go back and change to 4 and 2 to stop this vibration!) My solar system preheats the water, and the EcoSmart 24KW just adds the necessary energy to bring the water up to 120 degrees F. The EcoSmart 24 KW even heats the water just fine with the solar system not heating on a cold cloudy January day. I have a 3.3 gal/minute shower head (I measured with a 5 gallon bucket & a stopwatch), and about a 65 degree input water temp. A comment here: it seems that it is better to adjust your shower temperature with the cold water only. If your shower is too hot, turn on some more cold. Too cold(?), turn off some cold. That way the flow rate through the EcoSmart is not changed, and there is no feedback loop to adjust around. So after learning that, the system works just fine! I had to drill two new holes in the bottom of the EcoSmart to accept my two EMT connectors. The included hole/wire-clamp did not work out for me (but no problem. I just used a step drill from H. Freight to drill the holes). I used two corrugated copper tubes to make the water connections. No problem there either. EcoSmart says to use a wrench on its side of the connection, but the copper tubes say only to tighten one turn past hand-tight. Not much torque required. I used an 1-1/8" wrench anyway though. (There was not enough space to use a Crescent-style wrench). Another comment: our city gives photovoltaic subsidies if you install photovoltaics on your roof. The city wants you to have a solar water heater that preheats water for a 30 amp TANK water heater. And they require you to install a water heater timer so the water heater will be OFF during peak-electric-load hours in the afternoon (during 100 degree summer afternoons!) So this EcoSmart water heater disqualifies me from the city's photovoltaic subsidy program. If several people were to take a shower in my home during peak-load-hours in the afternoon, we might be drawing 100 Amps @ 240V during these peak-load-hours, which is what the city does NOT WANT (we won't do this). I opted out of buying the 27 KW EcoSmart because I have a 200 Amp main breaker and I have a heat pump heater with 60 Amp electric strip coil backup heat. I figured that the 18 KW EcoSmart was not enough for me and the 27 KW EcoSmart was too much (I figured I could blow my 200 Amp main breaker if someone was using a hairdryer (10A), the electric strip backup heater was on (60A), the dryer was running(30A) and then someone took a shower(112A for the Eco-27)). The Eco-24 seemed Goldilocks-just-right. Final note: my electric bill last month was $52, the lowest in memory for this all-electric home. Overall I am very happy. I give it 5 stars.

## Questions & Answers

**Q: i have 6 bathrooms, 2 laundry rooms will one do the job? or i need two?**
A: Hello Raz,Thank you for your question. I am replying in less than one hour, after business hours, to expedite your request.Actually it does not matter how many bathrooms your home has. What matters is how many points of use that you will use at the same time. So to determine whether this or any tankless heater will work, just add up the total water flow rate in gallons per minute ("GPM") of all your points of use. A shower flow rate can range from 1.5 to 2.5 GPM. A bathroom sink: 0.75 GPM. A clothes washer: 3 to 4 GPM.So, if you expect only to have one shower and one sink running at the same time, this will give you at least 105F hot water, if your incoming cold water temp is above about 55F.Please let me know if I can assist you further.Kind Regards,Ross KelsonGadgetsGoP.S. If you have found my answer helpful, please prefer us when you purchase. You will continue to get priceless service after the sale.

**Q: Will this Eco 24 system work with a dedicated 100A sub-panel off a 200A service panel?**
A: I'm not an electrician, but in your situation, all the power is coming from the main service panel. You should consult with an electrician to calculate your maximum load. I've had no issues with my Eco 24 running 3-40 amp breakers off a 200 amp service panel. If you have a heat pump you could be pushing the limit at certain times. Be safe, consult an electrician.

**Q: will this work to fill up small jacuzzi?**
A: Works on mine.  It appears many of these questions and responses are not for this particular unit.  The 24kw unit will do two showers and one other user in Indiana no problem.  Temp set to 125.

**Q: I understand this unit, the ECO 24, requires 3 - 220 (double) breakers. What amperage for each? 
I understand the ECO 27 requires 3 - 40 amp breakers. Same?**
A: 40 amp 240v breakers  (2 pole breakers)

*by K***R on 2 October 2015*

I had electrician to provide 3x40 amp. circuits. Fortunately, my brother is a PRO!! :) Plumbing does not require a pro. I have installed without any "professional installers". Gosh! how "professional you need to be in order to cut 2 3/4" copper pipes and use "shark bite" technology to install flex hoses... and teflon tape to seal connections :). Ran the water through the pipes for a minute to clear any air out of the system. All works nicely (as expected). Fine tuning the temperature now as 107F seems a bit too "cold" for me :) Keep in mind that the shower is on the second floor and the heater is in the garage. Separated by about 50ft of piping. Copper pipes work as a heat sink, so unless ALL piping in your house is insulated, you will have to continuously heat the air outside the pipes. So, account for that when you set your water temperature. Do NOT expect this be an "instant" hot water source. Logic will tell you that there is a "few" cubic inches of cold water already in the pipe that need to be pushed out to be replaced by the hot water. So. it will appear at the faucet not any sooner than the hot water from your old water heater tank. :).
