ECO 24 24 KW at 240-Volt Electric Tankless Water Heater with Patented Self Modulating Technology, 17 x 17 x 3.5

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.

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.

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. :).

Funciona muy bien solo que tienes que hacer una instalación especial, te recomiendo instalar paneles solares para evitar altos consu me la de electricidad

Genial aparato; gran producto q funciona a la perfección. No es de instalación para amateurs. Los arreglos eléctricos y de Plomeria son fáciles, pero de ninguna manera son para amateurs…sobretodo si este aparato sustituye a un calentador de gas con tanque de los tradicionales. Gasta luz. Mucha luz. Nosotros necesitamos equilibrar la carga para que no afectara el resto de la instalación eléctrica. El resultado es muy satisfactorio.

I installed the 24 for a secondary shower. It works fine in summer when the source water is warmer. It barely warms the water in winter. I have a 27 for the main shower and that works perfectly all year round. Get the 27!

Had for over a year now with no issues a world great, but does take a minute to warm up. As we are not home all the time it's better than having a tank heating up 40 gallons for the cats who can't turn a tap. Installation was as expected, bit tricky with the wiring for the 3 breakers because of the guage of the wire to easily move around the unit

Well made unit, stays nice and hot with a regular shower head but can't keep up the heat with the rainfall shower tends to stay warm not hot. Overall happy with the product
