  • Died right after the return window closed
Had it for two months. Used it to replace an earlier model of the same brand in a trailer that I bought. The old one was not working, so I replaced it. Had it for 2 months, using it maybe 3 times. It won't even power on. The instructions say that it may be caused by the supplied power or water flow, but both are fine. When it worked, it was impressive, but the short lifespan is more than disappointing. ... show more

  • As far as I’m concerned, it isn’t working.
So far I can’t get this to produce even warm water and I had an electrician put in a separate 30 amp. I’m going to try two more loads, adjusting the water any less water and I won’t have anything to go into the machine. If I can’t get it to work in a couple more tries, I’m returning this.

  • A little temperamental
Decent quality but the flow has to be just right or you get cold water on you.

  • Great instant water heater
This little water heater is no joke! I am shocked at how fast the water heats up. I personally did not install it but it seemed very easy for the guy who did. It works well and I believe we will enjoy instant hot water for years to come. Most definitely worth the money.

  • Product is trash
Bought this for our barn to take the edge off in colder weather. Finally got it installed last month and stopped working after the first week. We have tried reaching out to product support and are past the return stage. Do not waste your money

  • Great water heater!
Even though it’s 120 volt it takes a 30 amp breaker. Very good product.

  • No Heat
This heater does not enough water for an outdoor shower.
