  • Very Happy, very hot water
Model: V7B-180B
I love my water heater. I am in the Midwest USA and inlet temperatures are still very cold in May. It takes less than 10 seconds to receive unlimited hot water. After I installed the unit I needed to contact the company directly for troubleshooting my unit. They are in a different time zone so there was a slight delay in initial email response but when I was connected with my rep they followed through with everything extremely fast and with urgency. I am ultimately very happy with my unit and the outstanding real person customer service I received. I would absolutely recommend this brand water heater. ... show more

  • No hot water sent wrong hot waterheater
Model: V7B-180B
Dosest work , I am praying bought a limon the first time because the plumber& electrin getting the set up for the unit took much longer than the 1 MONTH WARRNTY PERIOD ON UNIT I did purchase another ONLY BECAUSE AT THIS POINT have 2000. Invested in plumbing & wiring for a unit exactly like this 1 it is a shame that factories which I do understand do have factory defects occasionally make consumers pay for insurance to cover the workers errors OR JUST COVER THE WORKERS mistakes out our pocket books. Why should I the consumer have to pay insurance to cover YOUR FACTORY to train tempory employees 200.00 is a drop in the bucket to some people but to others it is 1/4 of there monthly income ... show more

  • Great on demand water heater and they stand by their product
Model: V7B-180B
Worked perfectly but failed to a power issue caused by the electric company. This seller immediately sought to send a replacement. As they stated by the seller “ As a reminder, your water heater comes with a 3-year warranty, and we offer a no-questions-asked replacement policy during this period.” they stood by this and have replaced it without hesitation. Though customer service contact is via email, they have stepped above and beyond to stand by their product and their customer. Excellent seller! ... show more

Well built unit, heats well. Very pleased

  • Muy buena opción 😎
- Tiempo de entrega Excelente - Calienta y realiza la función según el flujo de agua, tiempo de espera 2-3 segundos y después tienes agua caliente a demanda el calentador es robusto lo que indica que tiene una muy buena estructura de construcción y se nota que está hecho para durar. - la instalación es súper fácil pero se necesita la ayuda de un electricista si no tienes las conexiones a 220v requerida la ayuda de otra persona ma está de más. Siempre he usado duchas eléctricas, que duran menos tiempo ya que la resistencia se rompe y los cambios y/o reparaciones salen caras. ^ Recomiendo mucho esta opción ^ ... show more
