Rudos1: Gets enough hot water for our mobile home and keeps the ampage low enough to work with our limits. We got a pro electrician and it was well worth it.

Ken Ruggles: Changed breaker to a 30 , but water still not very hot. OK for washing hands, better than cold water.

Jay: It is easy to install, level 3 (30 amp) is insufficient in alberta where I am unless you turn cold inlet flow way down that just makes baths impossible and showers just ok on full hot. Gets man hot, most women would find it Luke warm. Shower is good with a high pressure shower head otherwise it sucks on 30 amps. Works great on the sinks. I highly recommend running it at the full 40 amps if you want more flow in alberta. If a person could move it close to the shower it may do better but for me I'll need to upgrade the electrical to 40 amp 8 guage wire or go back to traditional nat gas/tank.

Amazon Customer: This product has saved us hundreds of dollars in a few months on our electricity bill. Our water is gravity fed from a natural mountain spring. Temperature adjustment takes a bit to get use to and adjust. Shower are awesome with endless hot water. This is my spring/summer review. We shall see how it performs through winter at -30 C

S. Marx: This works well in north Texas. We replaced our old 50 gallon water heater with this. I couldn't get a bigger unit because we only have 30 amps to that part of the house. Great that it is adjustable. In late spring and summer here, I have to adjust it to 10amps for showering OR leave it at 20amps and run a faucet on hot water because the shower flow is too light to keep the unit on unless the hot is maximized. I'll try removing the flow restricter from the showerhead. The negative is the flow adjustment in the unit. There's no high and low, it just spins 360°. The only way to adjust the flow in the unit is to have the hot water running, then go to the unit and feel and hear the water flow as you are turning the knob. Overall, after some trial and error, I'm very happy with it. I figure I'll need to use it at 30amps in the winter and will update my review if it doesn't work. BTW- Remove the water inlet and outlet (blue and red) plugs before installing!

km: I haven't had it long enough to comment on durability but it definitely gets the water at my taps and bathtub hot. It takes about the same amount of time to get warm water as it did from my tank wh. My house is about 850 sq ft.

I have it set to the 40a and the flow at the lowest. To be fair tho, I have a lot of water pressure, so I'm sure that helps.

If I open the kitchen, tub, and bath sink at the same time.. there's a noticeable drop in pressure but unless you're a psycho who takes scolding hot showers, the balance from the cold line will still give you a fair amount of pressure.

The installation instructions are garbage. I still have no idea how they expected it to be installed with that bracket. I took a couple 2 inch screws of my own and found the nearest stud. It doesn't weigh much, so you could even get away with not using a stud most likely.

On a side note.. it is impossible to find a 3/4 to 1/2 inch nipple adapter locally. So if you're like me and you want to use your existing 3/4 wh fittings.. you'll need to find it online. I didn't know it was called a "nipple" so it took me forever to find one!

Bilal Farooq: Up here in North the water can be very cold. So far this heater has been pretty good at providing instant hot water!
