Recomended. Works really well.
Works really well! You may have to drill a small hole in some of your faucets water softeners to flow higher gpm's as it will not turn on until it senses a flow of at least 0.7 gpm. Other than that the endless showers are scalding hot and draws under the rated max amps and its set on its highest temp @ 127°

Defective unit
This heater took a week to be delivered and never powered on after professional installation. After several emails and phone calls to the manufacturer's tech support, they have been unresponsive about my warranty claim. I am returning the defective unit to Home Depot and buying a different brand.

      Great Unit
      Bought to use for sink and shower in my shop, runs both at same time great. Uses a fair amount of power and takes a little bit to get going but overall can’t beat it for just over $500
