    • Great product
Pattern Name: Water Heater
Great product! I use these everywhere and my last one lasted me 10 yrs with only replacing a heating element a couple of times.

    • Works fine. Dropped my electric bill
Pattern Name: Water Heater
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. ... show more

    • Works Great! Expensive to install.
Pattern Name: Water Heater
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. ... show more

    • DO NOT BUY- TERRIBLE CUSTOMER SERVICE AND WARRANTY FOR POOR QUALITY PRODUCT
Pattern Name: Water Heater
We have had our Eco 24 installed for under 3 years and spent over $2000 between buying unit, upgrading electric and plumbing contractors. I've been underwhelmed by the performance- we don't get as much hot water as the write up says we should ie: can't take 2 showers at same time or run dishwasher or washing machine while showering and the water temp fluctuates constantly during a shower. Space savings was really the only benefit. HOWEVER, all of a sudden the whole unit started leaking water from inside the casing and upon speaking with the Plumber, he said the unit is definitely NOT repairable. I reached out to customer service and they asked for model, S/N and then told me the unit had not been registered but if I had all of the documentation to show when it was installed that they would honor. I had all of those things. Two days later when I followed up they told me this LIFETIME warranty didn't cover this and they would only have covered within 6 months. RIDICULOUS and not where I would ever spend a dime again. DO NOT BUY THIS PRODUCT OR DON'T EXPECT ANY SERVICE WHEN IT DIES AND/OR CAUSES ALL KINDS OF PROBLEMS. LIFETIME WARRANTY IS A JOKE. ... show more
