    • Doesn’t work as described. No hot water.
The water heater was super easy to install, but it doesn’t work so that doesn’t matter. We could never get it to go above 89°. There’s no adjustment so when they say it’s adjustable it’s not true. There’s no adjustment anywhere. They tell you to turn the water flow up to make it colder or turn the water flow down to make it hot but for it to even get to 89° it barely trickled out and then it would shut off because there wasn’t enough water flow. So after all of the trouble of installing it, we now have to take it out. Get a refund. Send it back and buy something else. ... show more

Don’t purchase not worth the money. Even though I read the reviews I still purchased it will trip the breaker had to get a bigger amp breaker even though it is a 110 it will trip a 20 amp breaker an I read this in other reviews. Always listen to the reviews. It gives warm water. Not hot water

2 stars for easy hook up. But with normal flow it doesn't get hot. Barely luke warm

    • Undersize cord and concerns about fire safety
Not sure how this is safe or legal. It requires 110 service with a >=32 amp breaker but uses a standard outlet (max 20 amp is available) and the cord is only 14 gauge wire? The cord and outlet are severely undersized. Concerned it would overheat and catch fire. Will return and go with a 240 volt product. ... show more
