Works well.
So far this has worked well saves on electricity takes maybe 30 seconds to heat up and then I jump into the shower.

Buen producto
Bastante cumplidor aun para lo que yo esperaba ya que solo requiero una cantidad relativamente baja de agua caliente y da bastante mas de lo esperado, totalmente recomendable

Tankless water heater
Great system, easy to install. Was a 1/2 day project but over all I'm very pleased on the outcome. The temperature is very easy to set and instant hot on demand was a plus. I did have to add a sub panel

Awesome, works great!
The unit was easy to install and I use the existing hot water tank as a preheat tank. We are on a well and the water is very cold coming up out of the ground, so I set the tank at minimum and it heats the well water to roughly ambient temperature. My gas bill has dropped by 70% and my electric bill has only risen about 3%. This is the only way to go!

Buen producto
Es buen producto, solo la instalción se complica por el cableado electrico que debe ser calibre 8 y que los interruptores deben ser dobles por el tema de 220V. Por lo demas puedo comentar que el agua se calienta rapido, se mantiene a buena temperatura (ajustable),
