        Answer This Question

        A:  There is a problem when you take a shower. All sudden it’ll turn the cold water for about a minute and then come back to heart. It also has a problem producing hot water when you use low pressure from the faucet.

            works well - unusual power cord
            Easy to install. Easily produces 120 degree water at 1.5 gpm, and holds the temp steady. Glad i didnt go with a lower kw or non-thermostatic unit. Realy like the way the display functions, lights up when flow detected and shows exact outlet water temp (you can see it ramp up). My only complaint is the short appliance cable coming from the unit. The unit does not have a termination for any standard conduit. The units instructions dont mention the appliance cable. They tell you to wire your own cable into the unit, but its very tight inside, so good luck getting #6 romex or thhn in there. Plan for a large junction box right next to the heater to splice up your #6 60amp circuit

              Does not maintain heat as I would like. When 8 run the hot water in my bathroom sink I can't use any cold water because the unit will lower the temperature and then turn off.
