I purchased this for our cabin. We have electric and water on the property. I hooked this up with pex crimp fittings and cold and hot shark bite shutoff valves. These valves aid me in removing the tank to drain it in the winter. We have one sink and one shower, this H/W heater took 18 min to heat up to 122 deg from 58 deg water. Blending the hot and cold water in the shower gives nice warm water for what seemed to be eternity. The only thing I had to do was chase the hot water threads with a 1/2-14 not die to clan the threads, I couldn’t thread on the fitting. The cold side was perfect and needed no attention. I love it and would Oder it again.
