  • Works as intended
Style: 27kW (APOLO)
I bought this for our barn, and the water entering the barn is very cold, which immediately heats up the water. I tried another one, but the heating time was a bit long. Make sure you know the temperature you entered so that you can buy the appropriate size.

  • Very nice quality works great!
Style: 27kW (APOLO)
We love this hot water heater! We have never had 3 showers going at one time, but did leave the dishwasher on once and we could tell briefly when it would kick on as the water would cool for a couple seconds, but picks right back up. We put this in a new construction home and are very pleased with the unit. ... show more
