Definitivamente el mejor calentador de agua que he tenido, silencioso, ahorrativo, calienta el agua excelente, definitivamente lo recomiendo, de hecho ya lo he recomendado a varios de mis clientes, soy arquitecto y estoy feliz con mi calentador

This is a review of the V53DeN. This is my second Rinnai tankless. The first was for the main house, this second for a master bedroom addition. I've had the first for more than 5 years and it's been wonderful. We didn't need 5.3gpm for a shower and a sink, but I trust Rinnai so I went with them again for the second heater. So far the unit has been great. My complaints have to do with the installation. I could have done it myself, but I hired a professional to help to make sure everything was to code. Neither of us could figure out the electrical from the enclosed instructions. We chased the wires in the diagram enclosed in the heater itself and figured out how to wire it, but no one should have to go through that effort to connect 3 wires. Also, the fitting for the electrical conduit on the bottom of the unit is machine thread not pipe thread. There must be a pipe-to-machine thread adapter that was missing from my unit. I will call Rinnai to find out. Again, the electrical shouldn't be this hard. It wasn't with our first unit. Finally, the box says "Wifi Enabled" but there's nothing in the instructions about how to connect. I don't care because I'm not connecting anyway, but it's just another way Rinnai really flubbed the documentation. Edit: I finally finished the electrical connections 2 months later, no thanks to Rinnai customer help, who eventually stopped responding to my emails. The connection at the unit looks like 3/4" compression to me. I've attached pics in case they help anyone. It's a tight fit and getting at the cleanouts for yearly descaling is going to be tough. I'd skip this model and look for a different from Rinnai.

Great product, order delivered timely and in condition expected.

Installed easily and functions well with no issues.

Very good investment
