Review: Works great - I love this water heater. I installed a large 120 gallon tub. I knew my 30 gallon water heater wouldn't be able to supply it, even just filling half way. I add water as it cools. I've been in there for over three hours. Pretty much use it like a hot tub. I hooked up the hot water into this heater's inlet. Being new England I would have to run water real slow in the winter for it to reach temp I want. Now I can run full volume. The water temp coming in drops to around 70. I can set output to whatever I want. For curiosity, I did turn off the tank water heater and had to turn the spigot down so it would make 115 degrees out I want. I love how it gives you so much data. Temp in, temp out, temp set, water flow, time running. I was going to hide it in the tub encloser but put it on the wall visible from tub instead. This way if I'm soaking for a long time and need to heat up the water I raise the temperature to the max... If you run off a well it might not be a good choice for a shower though. As the water pressure changes, the output temperature changes because it has to adjust to more then less water flow, as the pump goes on and off. When setting near the max temperature of 131 F. It sometimes would over heat and shut down. Display would show ED or something like that. I forget now. Don't turn water off if it does overheat. It will cool down faster with water flow and come back on when below set temp. The red ground protection lights are always on. At first I thought there was a problem. I was told by another reviewer they will flash if there's a fault. That's my only complaint. Red means fault in my opinion. I really like the look also. I bought blue, but the women reviewers like the pink also. Either way it looks great. The cost for the watts was the best out there. It cost me about the same for the wire, PEX, fittings and circuit breaker as the heater cost. Pretty simple to hook up, if you're handy and know basic plumbing and electrical. I used pex and have no problems. I was worried about the output connector getting too hot. Some places code requires copper for the first 18 inches on a conventional water heater. Not sure what they require on tankless heaters. Overall 5 stars plus.
Review: Works good for the price. - Works good so far.
