Customer Reviews for EcoSmart 6.5 kW 1.27 GPM 240-Volt Temperatured Controlled Point of Use Tankless Electric Water Heater

I added this product to my home and it worked well and helped tremendously with having hot water faster in my master bathroom. Would definitely recommend.

Love this product I put it under my sink to supplement my main water heater

My home is 2600 sq. feet and our family has been using this sytem for 2 years. Its great. The hot water is very hot. So if your tankless is not working to your expectations, get an electrician to install it. The amp and voltage is extremely important for this item to function accurately. Our family loves it,2 adults and 2 teenagers. My friend purchased a gas tankless and her plumber charged $1600 for parts and labor. Be smart, its not a do-it-yourself project, call an electrician

I had to run a new circuit to handle the 30amp requirement. The flow rate is reduced from what would normally flow out of the kitchen faucet but by setting the temperature higher than usage temperature I was able to use a mix of hot and cold water to get the desired flow rate at the kitchen sink.

Second try for EcoSmart; still disappointed. First unit burned out due to lack of water pressure. This unit needed six electrician hours to install and calibrate-- DO NOT attempt DIY. Two speeds: nothing or burn your skin off. Would not buy EcoSmart again!

I bought this to supply supplemental heat to my kitchen sink since the hot water is to far away and it takes close to 2 minutes for hot water to appear. My inlet temperature is 116 degrees. The heater is at 110 degrees. Warm water appears after 7 seconds which is great but then after 30 seconds the heater will heat the water up to 138 degrees. I provided a video of what happens and their customer support responded back that I should check my voltage. Which shows they did not watch the video

So far, it's been great. So nice to have hot water without endless waiting and wasting water. It works perfectly. Finger crossed that it stays that way.

POU 6T works fine I sized it to my existing electrical circuit which was not sufficient to serve the size unit that was needed. My breaker box was completely full therefore I would have had to do mort electrical work than I wanted to do.

Unit as described, but no chord or plug included; frustrating extra trip to Home Depot. Listing at time of purchase does not clearly recommend also purchasing the critical missing power chord.

I purchased this unit for single sink in garage it works fine for that it was easy to install once power was run to sink I did use a shut off valve on outlet of unit it made adapting sink hose easy and also it lets me slow down water flow as the aerators that came with unit did not fit my faucet

Does not work for a kitchen sink, not hot enough.

Unit heats water quickly and consistently, just what we need in our bathroom. Getting it registered for warranty very difficult. The numbers must be inside panel. Had somebody install for us and would need their help to remove cover to see if numbers are in there. Called number for help and they could not, just said to find a way to remove cover. So not able to register.

Used to take 2 minutes to get hot water to the upstairs bathroom sink. I resigned to just using cold water to wash my face. During a remodeling project I added the POU 6 and use the cold water line as input and now have hot water in 8 seconds. Very nice. The only problem is the warranty which requires a licensed plumber and electrician to install the unit in order to validate the warranty. Let's face it this is not rocket science. Run a 10 gauge 220 line with a 30 amp 220 breaker and connect a water inlet and outlet and you're done. Come on Ecosmart get with the DYI crowd and remove the BS requirements.

Easy to install and works great (so far anyway) for what I needed. It is installed in my kitchen in line with the whole home water heater to get hot water faster.

JUNK, JUNK, JUNK. MADE BY RHEEM. WORTHLESS CUSTOMER SERVICE. UNIT DID NOT WORK. I RETURNED IT AVOID ALL RHEEM PRODUCTS. THEY CHANGED THE NAME ON THIS UNIT FROM RHEEM BECAUSE THEY HAD SO MANY COMPLAINTS ABOUT THE RHEEM UNIT. SAME OLD WORTHLESS RHEEM JUNK. DO NOT BUY!!!!!!!!

This item does not heat the water unless it is just a trickle.

Heater works for what we wanted. It fluctuates a little at first but settles in pretty quick.

The heater is very good when entering water is cold. You can set the temperature and it will provide it. The Home Depot description says “Reads incoming water temperature; can be used inline with a whole home water heater.” This is where the problem is with this heater. When the incoming water gets hotter from the whole home water heater the POU 6T will not respond quickly. I have it set up for 115° F. I have measured temperatures over 150° F when the whole house water finally gets to the POU 6T. This can last long enough to read it on a Thermoworks Thermapen instant read thermometer. The product wants you to connect flexible hoses to it. This is a problem when you get the stainless steel covered hoses and then find out they have a tag that says “Do not connect to instant water heaters”. After seeing these scalding high temperatures I can understand the concern of the hose manufacturers. The warranty is useless for the DIY installer. To submit the warranty card you must provide your electrical and plumbing license numbers. Many DIY people may have the knowledge to install this heater but I doubt many have the required licenses to register the product. Home Depot should look at this when selling a product for which their customer cannot make a warranty claim. Home Depot should advising the DIY customer when there is no warranty. From a technical stand point the product looks very well built with all the correct electronics in place to do the temperature controls correctly. The problem seems to be with the pulse width modulator algorithm having too slow of a PID loop response.
