Rinnai V53DeN Natural Gas 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

I have had this only a couple of weeks, but it does what it is supposed to do. Heats water. I had a 40 gallon Rheem 9 yr, water heater that began making weird noises after just 3 yrs. So, I could get a warranty repair which is a nightmare. but, decided to upgrade to tank less. A couple of things to consider. This is not something a weekend do it your- selfer should attempt to install. I had a contractor do the installation as I had to step up my gas supply line to 3/4". I also had to have a power source installed The contractor also installed an electrical box with a dedicated circuit breaker, I also bought the service valve set and the in line water filter, The contractor installed a shut of valve in line so to change the filter, you just have to shut off the valve unscrew the filter, screw in a new one and open the valve (less than 5 minutes). I also have my water going thru a water softener, so will only need to change the filter every 9 -12 mos. instead of 6 mos, It cost me about $2,000 for the installation, but if you have 3/4" gas pipe, it will likely cost a lot less. Overall, I expect to reduce my gas bill around $50 or more per month, so it will eventually pay for itself. t This system heats water well and does not run out of hot water. Have not had it long enough to speak to durability, but Rinnai is typically a very good product.

great product

I'm an electrician with more than a bit of mechanical ability. It took me about 8 hours to complete the installation of this unit; water, gas and power. I was in no hurry. As for function, at its default it works great, really great. I have no need for the remote control for that reason. This unit provides enough hot water for a hot shower easily. Being single, this unit should suit my needs for a very long time. My only knock; make the skirt available, I had to order it from Lowes. Great unit otherwise.

Buy it. We have a much bigger rannai on primary residence and it is 12 years old and I've never serviced/flushed it as advised. We (2 teenagers me and wife) have had zero issues and the gals take lots of long showers, shave or whatever. Bought this one for a weekend tiny house/Park model RV/trailer. Much smaller capacity than my primary residence unit but happy to see it was the same quality, basic physical size and function . Just hook up 120v to unit for the ignighter, plumb in your gas and water lines and fire it up. Runs shower, kitchen faucet and bath faucet all on full hot with 115 deg water with no issue. Only have 3 fixtures so not sure how many more it could handle. Factory preset to 115 deg but changeable with dip switches to hotter or cooler. Came very securely packed. I installed service valves but will likely never service it. If I can get 12 plus years out of it without paying it any attention I'm happy. Doesn't come with a temperature controller but in 12 years we've only touched the one on my other unit when we moved it to paint the wall. We keep it set to 115 or maybe 120 default to be safe for any kids. That's too hot to hold your hand under anyway so never had a need to adjust. We have this unit plumbed to standard 20lb/30LB propane cylinders and it doesn't mind. Gained a free closet by replacing our tank unit with this one mounted on the outside wall instead of the inside wall.
