Excellent Water Heater
Water heater arrived to my home fast. Works great! I bought this to replace the identical water heater in my home. I have well water so I like to replace my water heater every few years. Installation was easy.

Works fantastic. Installation wasn't too bad going from tank water heater to tankless. I ran my own electrical (it's handy to be an electrician sometimes). Very pleased, hopefully it will last year's to come.

do not buy it. that's too bad . I bought 2 and the first one lasted 1 year. I thought I had been unlucky. The second one lasted a year and a half. They just don't work.

Replacement was easy, because I had similar thankless electric water heater installed before this one. And on the plus side my lights stooped flickering with this unit as apposed to old one.However after installation I have discovered, what this unit can't run shower 1.5-1.7 GPM and second faucet .5 GPM at the same time. I am not sure what the problem is, but water temperature drops from hot to barely warm as soon as I open second water fixture and stays this way. My old thankless water heater used to run 2 showers and a faucet quite easily at the same time. I am on the well in Pennsylvania so my water temperature is constant 63F-65F year around. I used diagnostic USB port, because I thought maybe one of the heating elements did not engage, but it gave me 0 error codes, witch means unit is not capable of ruining shower and a faucet at the same time, with incoming water temperature of 65F. I Have to return it and get the different one. If you wanna run just 1 shower, it is great, but for whole house application will not work.
