Perfect
To get a hot full bath is more than enough. Very happy with this heater.

Good unit for single sink
I fitted this in the kitchen to serve my kitchen sink rather than having a water tank heater. Unfortunately in the UAE water heating tanks are never installed with a water tray underneath so when they burst all the water pours into the ceiling. This unit works very well, however in the UAE you must just make sure that your electrical wiring can accommodate this type of unit. It draws a lot of electricity when it works so a thicker gauge wire is required.

Installation was easy. It's only been up and running for about 2 weeks, but so far it's working great.

Did NOT work as presented in the description. I had this product installed as a dedicated single SHOWER water heater. It was positioned less than 24-inches from a single shower head. I chose the 240 volt version of a tankless heater thinking it would be more powerful when we had multiple guests who could shower without the delay caused by the home's 40-gallon tank heater, which needed an hour to recharge with hot water. What a waste of money, installation expenses and time for this tankless water heater. I have had several Rheem tank heaters over many years that performed wonderfully, so I assumed I would get the same sterling experience in their tankless product. Major letdown. Then, because of Covid-19 restrictions, I was unable to schedule an electrician or plumber to install this Rheem tankless water heater in Amazon's required time period to request a refund. Then Amazon promised a reply to my refund request in 48-hours and I never heard from Amazon again. I tried cranking down the "hot water outflow valve" to the shower head as one user/purchaser recommended, but it resulted in a trickle flow of water that was useless for a shower. Pathetic product, a waste of money ($400 Canadian dollars) and frustrating experience all around.

El producto no es malo, cumplio su funcion al menos por los primeros 6 meses. Se le debe dar mantenimiento si o si, ya que la resistencia se cubre de sedimentos del agua. En el caso de que tu agua sea salitre, el mantenimiento es minimo cada 6 meses. El costo va desde 900 pesos si la resistencia se puede limpiar a 2700 pesos si la resistencia se debe cambiar. En mi caso especifico, solo hay un tecnico certificado por la marca , agendar con ese tecnico tomo más de una semana por su disponibilidad. Me arme de paciencia ya que para evitar perder la garantia todos los servicios se le dieron con el tecnico experto. La experiencia ha sido complicada, el calentador sirvio al 100 solo los primeros seis meses. De ahi todo es cuesta abajo… dificil de dar servicio, fallas constantes y alto costo de mantenimiento, hasta llegar a la descompostura total del equipo. El servicio de garantias de la marca en Mexico me rechaza la posibilidad de cambio, y que aunque en esta plataforma de compra dice que la tienda es Rheem, en realidad es un comercializador que esta en estados unidos y no cubre ninguna garantia. Conclusiones: no comprar este equipo si el agua de tu casa no es totalmente de manantial-no comprar este equipo si no eres electricista y plomero certificado- no comprar este equipo si no quieres perder dinero y tiempo.

Our Small bunkie at our cottage was updated and we installed this unit to replace a old school 40 gallon tank. The old tank took up some valuable space which once removed allowed us to expand our shower. The new unit is so small. I had it installed by a electrician and I did the plumbing which was easy. We have one vanity sink and one shower in the bunkie. I was a bit concerned that it wouldn’t give is the water temp we wanted but it actually works perfectly. I bought this as a reconditioned unit from Amazon and saved some $, it was basically brand new in the box.
