Rinnai V53DeP Propane Tankless Hot Water Heater, 5.3 GPM, Outdoor Installation

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

Previously, I had an old Electric water heater. I can't complain, it lasted 17 years with minimal maintenance. Decided to look into a tankless due to the electric costs being so high. I purchased an outdoor unit, since I didn't have any previous vents to the outside. It is super quiet and sometimes I have to go outside to make sure it is working when the hot water is on. The new Rinnai tankless has only been installed for a month but works great! Even survived the cold Northern Indiana winter so far. The heater has sensors to keep the pipes warm within the unit but be sure to protect the outside piping going to the unit from the cold. Hot water everywhere in the house and at the same time. Never installed a tankless water heater before, but with many videos on you-tube about Rinnai water heaters, made it easy and answered all the questions to know what to do. Two settings, Factory default is 120F, tested with a temperature gun and was getting 117F at the faucet. 140F degree setting is producing 133-135F at the faucet. If it saves on electric cost, it should pay for itself within a year. Should have done this years ago. Definitely has exceeded my expectations so far!

we bought this tankless hot water heater to replace the eccotemp we bought the heat exchanger leaked after a year this tank is so much better the pilefiter had it up and running in three hours from the box I love it so much I am buying another one for our RV great value

Have several of them. They work great, easy to install. Requires 3/4" propane line.

We installed this on a shipping container Tiny Home. The pipe fittings were tight and well made. The installation confusion centers around the electrical connections. First, the rubber grommet where the power wires exits the unit obviously does not meet code fo an external application and the grey plastic fitting does not match any PVC thread size. Secondly, the wires themselves are only 20 gauge. These do not seem to meet any code out there however after much searching of the internet, it seems that even professional electricians just wire up to it. We connected 12 gauge wire with wire nuts inside the cabinet and called it a day. The electric connections are supposedly only used for the LED display and the spark that lights the flame so we assume that gauge internal wire is ok. As for the PVC connection, we saw varied approaches to try for a water tight connection and we came up with using a 1/2" Schedule 40 female threaded connector pvc glued into their plastic connector. This connects to Liquidtite connectors and from there using those connectors and pipe into the container. This is the best water tight installation we could come up with that meets code. Lastly, it functions perfectly and within 30 seconds the water is quite warm and within a minute quite hot. All in all a very good purchase and other than the electrical connection very easy to install. We would certainly recommend it to anyone considering a tankless heater.
