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

We purchased this product 3 months ago. We have seen a reduction in our power bill, with very little increase in our gas bill. It is mounted out side so no more humming of a hot water heater in the house trying to keep water hot all day. It does take a minute for the water to run hot, that is not a big considering the tank is not constantly keeping water hot. We can run two showers at once, with just a slight change in pressure. The pressure change is not enough that you do not complete your shower and feel like you have not rinsed. Make sure you buy the package that Amazon offers, as we did, come to find out or home improvement stores do not carry the valves and would have had to order them. I love this product. We recommended it to my father n law and we just ordered one for his new home he is building. We have a 2800 square foot home, with 3 bed 2 baths, dishwasher and washer machine and it heats the water for everything amazing.

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.

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

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.
