    5.0 out of 5 stars Excelente opción, pero no es para todos.
    Reviewed in Mexico 🇲🇽 on March 4, 2018
    Funciona perfectamente, el agua caliente comienza a salir en menos de 1 minuto.

    En casa la distancia entre el calentador y la regadera mas lejana, está a aproximadamente 15 metros. Al abrir la llave de la regadera, en aproximadamente 1 minuto comienza a salir agua caliente. Una vez alcanzada la temperatura, se mantiene totalmente estable. Es sorprendente que un aparato de estas dimensiones proporcione tanta agua caliente en tan poco tiempo, y con tan buen flujo, pues la regadera que menciono es tipo ducha, no es una regadera "ahorradora", y caliente perfectamente.

    Ahora bien, todo esta maravilla viene con un precio, y es el consumo eléctrico.

    Lo tengo configurado a 35ºC y puedo medir el consumo energético de toda mi red eléctrica. Un baño de 15 minutos consume aproximadamente 1.5 KWh. Si consideras que en México, una casa promedio consume entre 5 y 7 KWh diarios, el consumo de éste calentador es enorme. Estos datos son para finales de febrero, en Guadalajara, Jalisco, en donde la temperatura del agua que se recibe del SIAPA es de alrededor de 20ºC. En tiempos mas fríos el gasto energético consumirá mucho más, en tiempos más cálidos bajará el consumo eléctrico.

    Necesitas considerar cuidadosamente si esto es una opción para ti, puesto que, dicho en pocas palabras, instalar este calentador en una casa o departamento implica casi en automático pasar a la tarifa DAC (Doméstica de Alto Consumo) de C.F.E. (Estoy en México). De manera que la decisión de compra debe ser respaldad contra lo que actualmente consumes de electricidad.

    Como guía muy básica te puedo comentar que si tu familia es de 4 integrantes, y usas agua caliente esporádicamente para lavavajillas, lavadora, etc, este calentador fácilmente te consumirá entre 8 y 9 KWh diarios.

    Yo tengo paneles fotovoltaicos, calculados precisamente para este tipo de consumos, de manera que este calentador es solar, indirectamente, pero solar, sin embargo, instalar un calentador solar de agua propiamente (de esos de tubos de vidrio al vacío) es mucho, muchísimo más económico.

    Otra cosa a considerar: Necesitas una instalación eléctrica a 220V. y en tu centro de carga requires un breaker de 60 Amperes. Considerando que en muchas casas, el breaker principal de la casa no pasa de 50 Amperes, necesitarás considerar que es probable que necesites actualizar tu centro de carga, tu breaker principal, en resumen... NO es para cualquier casa.

    Ahora bien, la tecnología que ofrece este calentador, la automodulación es realmente efectiva, no veo bajones repentinos de la intensidad de la luz mientras está en uso, pero definitivamente, el consumo eléctrico es enorme, fácilmente se va a los 50 Amperes en los primeros 30 segundos para lograr calentar el agua rápidamente, una vez que alcanza la temperatura, tiende a bajar el consumo un poco, pero siendo de paso, mientras tengas la llave abierta, el calentador sigue activo, lo cual, por un lado te da agua caliente interminable, por otro lado, en 1 hora de uso fácilmente puedes consumir hasta 13 KWh.

    Como verás, decidirte por este calentador depende de un cuidadoso análisis, solo es adecuado para situaciones MUY particulares.

    Thank god for breakers!!

    I ordered this heater on May 29th, 2021, it is now Aug 1st, 2021, and the attached pictures show what happened. This device was properly installed, and worked well for almost 2 months, until just last night, while having a shower the MAIN!! house breaker popped. Very odd, but after opening it up and seeing what caused it, I will never trust a water heater made by this company! I know understand why they specifically say the warranty does not cover 'incidental' damages. I wonder how many house fires they have cause?

    Just protect yourself. Do NOT buy a water heater from this company.
