  • Longevity
Model: ECO140B2
This has saved me so much space and works great. I have a small home with two bathrooms, I can run everything if I needed to and still have hot water.

  • Works great for me with no inconsistency
Model: ECO140B2
I've seen other comments that showed electrical issues resulting to burnt wires. Ive had this installed for a year now and its worked efficiently for me. Other users could have experienced bad installed with wrong type of wire gauge or loose connections but I would just double check everything and keep an eye on the unit after installing to be safe. ... show more

  • Great Water Heater & Exceptional Customer Service
Prior to installing the Tankless Water Heater, it would take ~ 1-½ minutes to get hot water to our bathroom sink. After installation, it takes under 10 seconds to get hot water. Within a 2-week period after installation I had 3 or 4 instances that the water was coming out at below the room temperature. I was getter 4 dash symbols on the display panel. When it did that, I had to push the start button and the hot water was back up and running. I E-mailed Ecotouch on a Saturday evening regarding the issue and to my surprise, I received a reply Sunday evening from Elaine. She said that the unit goes to a standby mode, i.e., the 4 dashes when there’s been a complete power outage. Another causse would be if there was a timer on the line. I assured her that we hadn’t had any power outages and there’s no timer on the line because I ran new line from the breaker box to their specs, i.e., #10 wire, 30-amp breaker at 240 volts. She requested all the info regarding the Amazon order, and I sent that info the Monday. On Tuesday, I got an E-mail from her that she arranged to have a new replacement sent. On Wednesday, she sent me the tracking # and on Saturday I received the replacement and it’s been running great. As far as Elaine’s customer service, it was fantastic, it’s been many years since I experienced customer service like that! The water heater is well built and comes in a custom heavy duty walled cardboard box I have mine set for 110° F and I checked the water temp with a thermometer at it runs exactly what the setting is set to. ... show more

  • Hot water heater

Heats up fast, running just our hot tub but it warms to 105 degrees with in moments and fills the whole tub to the exact temp

  • Looks nice, installs easily. If only it could heat…
Installed according to instructions, running on a 30A 240V circuit, this thing can’t even keep up with one sink. It will only heat if flow is less than 0.6 gpm, but according to their chart, at my inlet temp it should be able to heat at 1 gpm. And that’s not all. If this unit loses power, it does not return to the previous power state when power is reapplied. So, for example, if your power “blinks” during a storm, you now have no hot water until you manually turn this heater back on. Mount it in an easy-to-reach spot, or you’ll be sorry. Sure enough, you really do get what you pay for. ... show more
