    • Seems to be working fine

Seems to be working fine a little delay before it comes on but it’s a lot quieter than my old gas tank

Review Image by D403j D403j
The media could not be loaded. Pros Installs decent enough. Lightweight. The setup for the WiFi is a breeze. Cons says supports up to 6.5 gpm but that is simply not true. At around 5.5 (2 showers) I get 109° max. Additionally, sometimes there are wild swings in temperature without doing anything like turning faucets on and off. See the video, set at 125 but it doesn’t even get that low before it’s reaching 150+. I’ve seen it get to 165 and error out. I’d recommend if you plan on having 2 showers get the 35k. But otherwise I’m satisfied Added a star, after a few months I’m satisfied with how quickly it works. ... show more

    • Work is going well saving costs
This unit is a perfect fit for my 3-bedroom/2-bathroom, 1500 square feet residence, effectively meeting the needs of the entire household. Set at 140°F, it can simultaneously handle two showers, with some extra hot water available for the bathroom sink or kitchen sink. If you have no knowledge of electrical work, do not attempt to install it yourself, as it requires a substantial amount of current to operate, needing 75 amps of power and (2x dual pole 40 amp breakers). Ensure that your electrical panel has sufficient space, as it requires five #8 wires to pass through a 3/4-inch conduit for power connection. If you have any doubts, please have it professionally installed, and make sure to read the required wire size. Compared to traditional bulky water tanks, it saves a significant amount of space. Overall, I am very satisfied with this device, especially since we have three children. Running the dishwasher, doing laundry, and taking showers can require a substantial amount of water for us, and our previous 50-gallon water heater couldn't keep up. This water heater performs exceptionally well, maintaining water temperature consistently. I hope this information is helpful for those considering purchasing such water heaters! ... show more
