  • Great product
Style: 18 kW
Works great, fairly easy to install. I did add some other features that may have not been needed like special shut off valves with a pop off valve, which included a way to drain the unit and added a back flow preventer. These items will make it easier to service in the future and safer

  • Works 🤷🏿
Style: 18 kW
It works as it should. There were some loose connections inside the unit which wasn't much of a problem. My only complaint is that it doesn't ever really turn off fully like my rheam which only lights up when water is flowing. This unit stays lit displaying the current temp at all times. It will be around 68 so I know it's not pulling power to heat when no water.is flowing but it's kind of annoying because I'm used to my rheam and my grandmother's ecotemp which stays off until you turn on hot water. ... show more
