The best thing about this new model is that it meant I found the older model on sale. Don't need any kind of integrated, learning recirc pump.... just heat my water!
I think the biggest advance in tankless and tank water heaters would be a automated lime/calcium build up flush system. It is the biggest killer of water heaters.
I installed this exact model 17 months ago at our cottage. It works PERFECTLY! I have it set at 110 degrees, and you don't even need to turn on the cold water for showers at ALL. Even at 110, you get steam on the mirror. My only critique is that we had it professionally installed, and they required strict vertical venting, even though our old LP tank had an elbow vent, and an always-on pilot light. This requirement is ridiculous, as the only time the water heater is burning propane is when you turn the hot water on. As soon as you turn the hot-water off, the unit takes about 5 seconds to shut down. Totally efficient! You need to let it run for a good 30 seconds before you get hot water, which isn't a problem at all. It runs on 110 electrical, and our propane bills actually DECREASED at the cabin because we aren't heating the same water over-and-over again as it sits in the tank between demands. The other hiccup - which wasn't cheap - was that it requires a 3/4" propane line to feed it. That said, if I could do a rewind, I would have probably installed it myself with a dedicated 30lb propane tank. I'll guarantee that - for the average user - that is 2-3 years of fuel. I don't know about you, but my family takes 10 minute showers. Our unit provides enough hot water for two bathrooms plus a kitchen at our cottage. We host a lot, so - even after having 8-10 guests for several days, you never run out of hot water - ever. The ground temperature for our well is 36 degrees on average. Within 30 seconds, that water is heated to 110, even if someone is taking a shower while someone else is doing the dishes in the kitchen. The maintenance? I got a small submersible pond pump, and fixed it to a 3.5 foot garden hose adapter, and then I shut off the main water feed, open the auxiliary feed, put the pump into a 5 gallon bucket directly below the unit, add about 12 ounces of white vinegar, and run the thing for 5 minutes. The water circulates, and eliminates any film that may have built up inside the unit. Then, I shut it off, reopen the main water feed, and bleed the system for about 2 minutes. I've done this twice in 17 months. The unit works PERFECTLY. Rinnai - to me - is the only choice. It cost me MORE to have it professionally installed than it did to purchase the unit. Live and learn, I guess.
We have an older one installed a few years ago one of the best buys for our house. Love the non stop hot water. Have a bunch of people wanting to shower no problem!
My outdoor Rinnai is 4 years old. 199,000 BTU's. The first year I flushed it twice. I have flushed it once a year since. This year while flushing I pulled the flame rods and cleaned them. They were mildly dirty and really didn't need cleaning but I did anyway. I also have just about every part on hand as a spare. I haven't had one issue and it's a builder grade model. I wish the builder put in a recirc line but he didn't. I could probably easily run one to take advantage of this new model in the future. My model doesn't condense so I don't have to worry about neutralizer media either so that's another plus to keeping it simple.
I'm installing an RX130 today, really like the new tech and high efficiency. Great to know yours lasted 20 years+ It feels odd that the manual states to pour 10 oz of water in the exhaust port on initial start up. But, I guess that's like priming a dry system. Thx for the vid! Update, my bluetooth did/does not work. 120 degree setting did not provide 120 degree water. I had to manually enter parameter 01B to allow me to set it to 130 and then all was good. Just an update to help others. Install took 2 hours;)
Seems very similar to the Navien model. It’s a great unit also. Replaced an 80 gallon gas water heater on a recirc line, best appliance purchase I have had. Endless hot water for filling hot tub plus the intelligent recirc always has master shower ready for instant hot shower in the morning.
Can you make a teenager setting kills hot water after 30 minutes for 24 hours to that shower. This setting will pay for the unit in a few weeks time in my house.
Looks like they’re finally coming up to navien tankless standards. They’ve had built in intelligent recirc for years now and outdoor vent cap, and 98% efficiency, etc. good to see rinnai is finally catching up
@@epiphany6 Navien is also great if you like it recirculating it's own exhaust gas. They leak right out of the box. Navien claims using soap bubbles and watching them leak is acceptable. lol
Tank still wins imo in most cases. Dumb, reliable, works when the power is down, easier to routine clean, no major line changes needed for a large power requirement. Can we now appreciate after 2 or 3 decades of tankless as a realistic option the minor energy savings in most use case scenarios just aren't worth it? A smart valve for nat gas vs propane? C'mon, gee whiz tech sure, but we're talking a 5 min operation done once in the lifetime of a unit. It's just asking for trouble. That said, I love tech in my life. Just not in ho hum places where I want absolute max reliability and absolute set it and forget it simplicity. Great video material as usual, no complaints there.
I used to think the same, but I went to tankless because I didn't have enough space. After trying tankless I will NEVER go bank to a tank heater. I like having endless hot water. I like having the option to take a shower as long as I want when the rest of the family is also using hot water.
Yeah except when the tank leaks on Saturday night at 2am and 20 gallons of water leaked out into my finished basement out of a 75 gallon tank before I could get down to shut the main off. Bradford and White Power Vent tank with soft water system in house and whole home filter and the tank only last 9 years. Routine flushign performed but not enough height above tank to replace the anode rod. New tank installed in NJ $4400. So no it doesn't win in every scenario.
Nice video, man. Ansswered my questions. BTW, I spent 30 yrs in Austin, great town! But I gotta say, it was a better place in 1995 that it is in 2025, LOL!
@@ToddBizCoach I bought the unit from Lowe's for about $1500. It was their RX199i model. I didn't get the recirculating pump since I'm in So Cal with warmer weather. Seems to work good.
The image on their website showing the Versa Vent for this model looks like there's also a cover available for the piping? That sounds like a nice add-on for when you get those freak cold spells. We had one of those this past year, and a friend of mine (who has an external tankless water heater) had to keep his hot water running all the time to ensure the pipes didn't freeze over.
Sometimes I am impressed by how far in front the USA is in building science, then there's times like this where I am like - we've had all that tech in the UK/Europe for at least a decade. Great investment for anywhere that doesn't have space for a heat pump or the available electrical supply.
I have the 220V version with the electric elements and I have never had to use them even with 8 people taking showers back to back. I guess the endless showers of the tankless is awesome for homes with tons of people@suspicionofdeceit
Apples and oranges. How could an appliance producing heat be more efficient than one that exchanges it with the medium in which it is immersed (air, water or soil)??
We are looking at adding a new tankless water heater. Rinnai is recommending the RXP model instead of the RX model. I live in Houston. And don’t know if it’s worth the extra $300. Any thoughts?
I have an aging standard propane fired water heater tank and a new Grundfos smart recirculating pump with a 2800 SqFt two story house with only three people. Is a unit like this or a heat pump type unit the best option? California electricity is ridiculously high in price.
You lost me with intelligent. I’ll start buying “intelligent” appliances again when they start using commodity PC brains instead of custom ridiculously priced brains.
If it last twice as long with maintenance, what is the costs of said maintenance over that time period and which costs more in the end? My gas was 1.75 a unit last month, what is the point?
Could you kindly update the title to specify that the video is for gas/propane? I spent some time watching, assuming it was for electric, and just wanted to help avoid confusion for others. Thanks so much!
we do that in MN because out water is very hard. I have a big blue whole house filter going to a water softener before it gets to the heater. It helps reduce the build considerably and this is from a city with 21 grains of hardness.
Our village had 23 gr hard water and for decades our water heaters died a horrible, noisy, gurgling lie-filled death at 7 years... even using a whole house filter. I switched to a water softener and adjusted it for a 7 gr hardness output and my present gas fired and power vented water heater is like new after 11 years. Nothing inside to flush out. ;-)
Would this ability to switch between NG and LP from the app itself allow a sort of dual fuel type use? Say, on the off-chance the gas supply is out somehow or, as here in the CA market, NG use for water heaters gets increasingly phased out, which is supposed to be 2026 for us?
building a home here in Colorado - the challenge I hear from builders is that water coming to the unit is 45-50 degrees and tankless can't keep up with needing to heat and distribute hot water.
Sized properly the temperature rise is not an issue. I have the opposite problem in Arizona, where the incoming water can be 100°. The tankless will vary the burners to deliver the correct temperature. If it’s sized incorrectly, they work beautifully. The proper sizing includes gas piping too.
Does anyone know if one of these USA units would work with a transformer in a country with 240 volt 50 hz, with the transformer producing 120 volts 50 hz.
@@buildshowI recently watch a video on gas hot water tanks, and apparently there’s a difference between say “Home Depot models” and “plumbing supply house” models, even though they’re identical model numbers and such - is that true with Rinnai tankless heaters as well? Or is the one at Home Depot the exact same one a plumber would get, just without the markup?
There's already electric tankless... and to keep up with a whole house it's 120 amps... there's 0 compelling reason for this when you could have a heat pump.
Anyone living south of Canada should absolutely avoid this and go with a heat pump instead. Don’t screw over your customers, guide them to the best solution which is almost always a heat pump.
I only have a 120v outlet that is shared with my washer and dryer and after my elec car charger i have maxed out my electrical service to the house so a 220v line for a good heat pump w/h isn't in the cards for me. Tankless seems like great option for a 3 person townhome such as myself...
Sanco2 is the only heat pump water heater we have in the US and its very expensive, does Canada have more choices available? Well theres also Mitsubishi, but their water heat pump is only marketed for industrial install.
I LIKE THE WINDOWS U TALK ABOUT PELLA THAT U DO FROM THE INSIDE. I LIVE ON THE EASTSHORE OF MD. MY HOUSE IS ALL ELECTRIC, CAN U RECOMIND A COMPANY THAT HAS A GOOD ONE FOR A 1675 SQ. FOOT HOUSE 2 STORY.
Ok so these features are convenient for installers, but just adds to complexity that does nothing for the homeowner, just will make it more unreliable over time. Did Rinnai introduce any new models that actually are performance improvements - not installer hacks? As another commenter suggested, an automated lime/calcium flush system would be useful. Having both natural gas and propane components inside the same unit is a gimmick that is only useful for installers who don't want to carry two different units in the truck.
More crap to break. I manage a 7yr old building with 32 of the older RU199i. They have been the biggest garbage I have ever dealt with. Out of the 32 units, 19 have had to be replaced. THEY ARE BARELY 7 YR OLD. Bad heat exchangers that bust and flood areas, Leaks from the seals, where the pipes use those stupid clips, bad valves and boards, I could go on. I found your video because I just now installed one of the new re199in and the QR code does not work so I cannot program it. I load these tankless water heaters
I appreciate the feedback. That’s a good idea. I like going over the individual specs on particular units. I enjoy the nitty-gritty details of these particular units.
That's great if you want/have Gas (of some sort)... 2 questions: First, is it available for Electric use? (I care about the Planet, and the continued use of Fossil Fuels.) And Second: What is the max Water Temp available to the Home Owner? (If you say "125 degrees, of course"...Thant's a non-starter. I just replaced a Water Heater, and had a HUGE argument with the Plumbing company to set the WH Temp to 145 (the max available.) I shower at at least 130 degrees (no, really.) If you try and run your WH at Max without mixing Cold Water in, you lose Capacity (whether heated Tank capacity, or BTU Throughput in a Tankless.)
How much are you getting paid to shill for Rinnai? Navien has made far better heaters for years. And each time Rinnai made a change to it's tankless heaters they looked more and more like Navien. Why not go with the one that has been doing it for years. I work on all brands, so I don't care what you buy.
I don't understand the need for Matt to push a gas product that contradicts his philosophical views of creating tight, clean, energy efficient homes. Heat pumps are the future.
Newsflash: a tight, clean, energy efficient home can also use gas. It's not Matt's job isn't to reflect your personal views. (also, a big chunk of the electricity needed to run those heat pumps comes from coal and natural gas)
@@Pepe-dq2ib No, there are a dozen heat pump water heater options in the US. The Sanco is a novel concept but quite expensive and limited distribution and support options. BTW, they all have great government and utility rebates as well.
I definitely like heat pumps and do love a tight/efficient house indeed. However, there is definitely still a place for gas appliances in American homes. There is no perfect water heater for every situation or house. Choice is a good thing and Rinnai makes some great equipment. I’ve seen their units give 20+ years of trouble free service.
@@buildshow Matt, I greatly appreciate your time to response to my post. I still think it be good for you to encourage folks to go more efficient. As one of the leading voices for the building sciences online, you might want to do a quick recap/overview at the beginning of each of your videos when covering a topic like this, especially one that might contradict your ethos. Saying something like, heat pumps is the way to go and how I choose to heat my house (and what I recommend to clients), but if your space doesn't or an electric panel doesn't allow for it, this might be a good alternative.
The best thing about this new model is that it meant I found the older model on sale. Don't need any kind of integrated, learning recirc pump.... just heat my water!

Yes good deals can be had right now as they clear out the older models.

I appreciate the feedback. That’s a good idea. I like going over the individual specs on particular units. I enjoy the nitty-gritty details of these particular units.
Orifice?
I thought Matt was about green building. Ditch the gas and let's talk some heat pumps!
Stop with the ap crap. Why on earth do I need to add an ap for fricken water heater.
Who wants to bet that the data from your water usage is sold
Is that background music AI generated?

A quick look suggests that the price just went up about $500.
Navien is my first choice then Rinnai but Rheem tankless Never Ever
😅😅😅 Ooh eine gastherme. Sowas gibt es schon mehr seit 60 Jahren. Wie rückständig seid ihr bloß.
I bought it and regret it, the recirculation pump is insanely loud, can hear in whole house
Meh. Unless you have severely limited space, do yourself a favor and buy a hybrid heat pump water heater. Way, way more efficient.
Yeah you have one in your house because the company most likely gave you one for all the plugs.
This is a just a commercial for your sponsor. I come back to your channel just long enough to get reminded about why I unsubscribed.
That's great if you want/have Gas (of some sort)... 2 questions:
First, is it available for Electric use? (I care about the Planet, and the continued use of Fossil Fuels.)
And Second: What is the max Water Temp available to the Home Owner? (If you say "125 degrees, of course"...Thant's a non-starter. I just replaced a Water Heater, and had a HUGE argument with the Plumbing company to set the WH Temp to 145 (the max available.)
I shower at at least 130 degrees (no, really.) If you try and run your WH at Max without mixing Cold Water in, you lose Capacity (whether heated Tank capacity, or BTU Throughput in a Tankless.)
Unless it can run off free solar energy, not interested.
This things a piece of shit, had for 4 months and broke
No thank you, if you have a dedicated recirc line dont go with this one just dont its not worth it
Sponsored by Ranai… sounds like an advertisement….next
How much are you getting paid to shill for Rinnai? Navien has made far better heaters for years. And each time Rinnai made a change to it's tankless heaters they looked more and more like Navien. Why not go with the one that has been doing it for years. I work on all brands, so I don't care what you buy.
I don't understand the need for Matt to push a gas product that contradicts his philosophical views of creating tight, clean, energy efficient homes. Heat pumps are the future.
Newsflash: a tight, clean, energy efficient home can also use gas.
It's not Matt's job isn't to reflect your personal views.
(also, a big chunk of the electricity needed to run those heat pumps comes from coal and natural gas)
isnt there only 1 true heat pump water heater int he market now? I believe its the Sanco that Matt did a review on earlier this year.
@@Pepe-dq2ib No, there are a dozen heat pump water heater options in the US. The Sanco is a novel concept but quite expensive and limited distribution and support options. BTW, they all have great government and utility rebates as well.
I definitely like heat pumps and do love a tight/efficient house indeed. However, there is definitely still a place for gas appliances in American homes. There is no perfect water heater for every situation or house. Choice is a good thing and Rinnai makes some great equipment. I’ve seen their units give 20+ years of trouble free service.
@@buildshow Matt, I greatly appreciate your time to response to my post. I still think it be good for you to encourage folks to go more efficient. As one of the leading voices for the building sciences online, you might want to do a quick recap/overview at the beginning of each of your videos when covering a topic like this, especially one that might contradict your ethos. Saying something like, heat pumps is the way to go and how I choose to heat my house (and what I recommend to clients), but if your space doesn't or an electric panel doesn't allow for it, this might be a good alternative.
gas? really? taking a big chance on a future outlawed energy source 🤣🤣🤣
