Tankless hot water heater
Previously I bought another brand tankless hot water heater with similar specifications to this one and installed it about five years ago it was always problematic sometimes hot water sometimes lukewarm very sensitive to adjustment and water flow I regretted installing it and was tempted to go back to the traditional type of hot water heater but I had used the space where it was originally installed I bought this under duress and installed it however it is amazing twice the amount of water pressure there is no fluctuation of temperature the temperature is constant it is great like day and night from my previous experienceVerified purchase: YesCondition: New

Quality questionable!
Unit was DOA! I paid an electrician for three hours labor doing diagnostic work on it to discover that the units would not turn on to produce hot water. I have a 24KW unit manufactured in 2023 that works perfectly. This unit has failed right out of the packaging. I have made a request from customer support but have not heard anything at this time.Verified purchase: YesCondition: New

Tankless hot water heater
Ordered it , Was lots less expensive than I found anywhere else. I was skeptical at first. It showed up to my door quickly. I opened it up and everything was fine and ready to install and is working so far amazingly well ! The tankless heater I purchased is top of the line and I’m excited to see what kind of savings I’m going to get if any ? I’ll know in a month or two how much it costs to operate it.. compared to my old school heater … everything went well!Verified purchase: YesCondition: New

Excellent unit
Replaced an 8 year old ecosmart. Essentially the same unit. Somehow this one is far better than other. Able to set water temp to lower temp and more comfortable. Would highly recommend unitVerified purchase: YesCondition: New

Awesome
This water heater is perfect for my little house, endless hot water. Was somewhat of a challenge to DIY install but I made it happen. This unit drinks lots of power. Be sure you have room in your panel. Shark Bite fittings with copper plumbing is essential, much faster. Would definitely buy this again.

More hot water
Of course this is new, and we don't know how long this unit will last with the hard water we have in Wesr Texas (scaling), so far it is wonderful. It provides much more hot water than our previous u it, and will not run out, since it is an on demand unit. It was easy to install.Verified purchase: YesCondition: New

Replaced my old Rheem 27KW with newer version with upgraded ground. Great water heater, use it in my 3,950 sq/ft home and it works flawlessly for the entire house. Can run up to 7 gpm at 116° on average in WV.Verified purchase: YesCondition: New

easy to install, no problems.just remember you need three forty amp.breakers, so don't buy unless you have a 200 amp entrance.
it gives us unlimited amounts of hot water, even though I live in Maine, with really cold water. had to turn it down, because water was to hot.Verified purchase: YesCondition: New

Good product.
Haven't has a chance to install it yet but I probably will. I had one purchased a couple year ago. It worked really good, very quite, no noise, and very reliable. I would recommend it. PaulVerified purchase: YesCondition: New
