Rinnai Water Heaters - Other things you should know

[@Order-in-Chaos]

3:14 is great for using only the water temperature that you need out of the hot but that's in lala land or back in the old days. Today's shower valves are mostly thermostatic and are supposed to temper the hot water that's usually coming out around 120deg. If you think you can set the unit to come out around 104deg. and turn the hot knob all the way to the left you'll definitely have a bad experience taking a shower. Your water will be uncomfortable and the pressure will drop in half.

[@scottnra]

It would be better if you actually tried it before gussing. Most people shower at 104 - 106*F of mixed water temperature. and you can set a Rinnai and most other tankless water heater to the lower setting and they do just fine. The shower heads are 2.5GPM rated at 80PSI in a lab. You don't have a lab, or 80 psi, so your actual flow is considerably less unless you tamper with the heads. You certainly can operate today's shower valves that way. Only a few will have a little cold still mixing in. At the very least you may still set the heater lower as there is not point to heat it way up just to cool it back down again for use. With a tank, you don't what the temperature is. You set it on a dial that says "Hot, hotter hottest" or "A, B, C" plus the temperature swing in a tank can be 15 - 20* of more depending on where you catch it in a cycle. Google "Tankless 101" for more complete info.

[@scottnra]

I'm not sure what all the fuss is about here. While it may be not 100% accurate with some faucets, it is for a lot of others. A KZbin video is a hard place to outline every single little variation and detail of anything. There is a lot of VERY good, solid information in this video about a great product.

[@dallasgary8421]

its important people realize, there are companies trying to make money off selling you a tankless.. YOU must understand the pros and cons of tankless.. they are not perfect, but much more efficient than anything else on the market. $8,000 to refit a water heater location to handle a tankless is not unheard of. I too, have gone to several places to repair or replace tankless heaters and 80%-85% of the problems with the tankless is from faulty installs. I repair tankless' all day long.. Rinnai is the one I rarely have to fix.

great post!

[@ONLYinANTARCTICA]

Good tip in setting the temperature between 102F to 106F to save energy instead of 120F and using the cold water to bring down the water temperature.

[@dudeman8323]

Not accurate. The flow rate reduces so if your usage temperature is the same you're using the same energy. The difference is only which pipe the energy is flowing in...

[@Nicholas175]

yes, we can take a shower simultaneously in all three bathrooms, and run the washer or dishwasher. Make sure you have volume to the house, then step down for pressure.

[@FuelSaverusa]

I just seen my new house will have a Rinnai System for our hot water needs. I wasn't sure if I was getting tank-less because of budget. Glad my builder is looking for some positive remarks from us finally. My warranty says 5 parts 5 labor is this not true?

[@scottnra]

Since this video was made the Rinnai warranty has gone to 5/5/12 for residential installations on the Luxury and Ultra series units.

[@FuelSaverusa]

Thanks Scott

[@caseycarver3272]

Saw, not seen

[@IronhorseMike]

Do you have any maintenance videos? Have you had any problems with Rinnai units drawing in moisture through the Factory concentric I/O pipe and flooding the motor assembly? Its happened 3 times in 5 years on a R94LSi that was professionally installed. Also any videos on using the dollar bill method to clean the rod? Or blowing carbon out through the manifold?

[@MSSpenceProductions]

Good Info, but New Zealand is not part of Australia. What is the pressure like from the 53 series? Is there a pump or something?

[@clubsecretary8676]

Rinnai tankless water heaters are very sensitive to scale buildup in the heat exchanger. To keep high efficiency, you must descale often. Before the warranty expired, my heat exchanger burst, fortunately while I was nearby. That's when we found out that the warranty is not very good. Yes, they covered the cost of the new heat exchanger, but did not cover any other parts that they felt should be replaced (just in case) or any labor charges! I was forced to purchase another tankless heater while the parts were ordered in and installed.

[@patrickmckowen2999]

Sorry to hear of your troubles. What would make one tankless heater more susceptible to scaling compared to others? I am in the market for a tankless so I am am researching common issues with various brands. Cheers Patrick

[@richardcain8385]

I got 4 years out of my unit, even the factory can't figure out what is wrong with it. Would not recommend this as a good purchase.

[@sjhanksaz]

With this unit could you run two showers and a dishwasher or clothes washer at the same time?

[@rowinsambath5970]

Very good video about tankless water heater

[@davidbrinkman4834]

Can I combine a Rinnai water heater and a Rinnai boiler to the sane existing vent pipes?

[@chshincooling]

What model is that?

How far does a gas tankless water heater have to be from outside electrical panel box?

[@10469]

Love this product, it’s so amazing

[@mattm5867]

’m currently having built a log cabin on a trailer from Lancaster log cabins. Included in my cabin is a regular tank water heater, but I sprung extra $ for a tankless water heater. They install the water heater outside on the rear of the trailer. In speaking with a few friends, most have agreed concerns about the water heater freezing in the winter months when no hot water is sought. I know nothing about these systems, although I’ve attempted to find out info on them. I can still have them put a tank water heater in, I’m not sure which way to go. I’d like to use the cabin in the winter months, It is going to be in the poconos (Pennsylvania) I may try to winterize each weekend I’m done using. In your professional opinion would it be better for me to just stick with the tank water heater or get the tankless? Any info you can provide would be greatly appreciated. Oh the tankless water heater is made by rinnai on demand V53dep

[@robertpeasley7188]

My unit froze and split last winter, cold air came in through the exhaust. I live off grid so, only have electricity part time. Would that be the reason that it froze and split? Do these units need power 24/7?

[@VinnyGjokaj]

+Robert Peasley Yes they do need power at all times, If there's no power you're supposed to open a faucet and let the water drain out, that goes with everything with plumbing though! Outdoor model water heaters have internal heaters that heat the system to freeze protect it, and indoor models don't, but the internal heaters does not protect that copper or plastic plumbing!

[@petesessa2041]

For a water heater that's "projected to last 15-20 years or more," a ten year warranty for the tank and 5 for the parts seems to be a little disingenuous. Your warranty tell us what you really think think about it's life expectancy. It's the same as reservoir system.

[@penzoil11]

Does it make much sense for a company to warranty a product (such as this) all the way up to the end of it's expected life? Wouldn't that mean that roughly half (assuming a normal distribution) of the units would fail before the warranty expired (in this case 15 years)? Doesn't seem realistic - they would get killed. Car companies typically warranty for 75 - 100,000 miles, but we expect the car to go much longer than that. No, I have nothing to do with Rinnai.

[@petesessa2041]

OK, lets try to forget this obvious attempt at sales-training-gone-wild and forget this guy is pitching on-demand water heaters that MIGHT last 15-20 years or more. Lets say the on-demand water heater costs $3,000 (non-condensing) -$4,000 (Condensing) and the average consumption of 20 gpd to 62 gpd is employed. The average savings of a gas-fired on-demand water heater is about 37%. (23% on the low side and 55% on the high side.) That puts the annual gas savings between 42 to 95 therms. The annual savings costs would be between $42.00 to $121.00 per year. When you factor in the very high cost of installation the amount of time it would take for these things to pay for themselves, you would think "a wake-up call" would be in order for those pitching these things, and those who are catching a lot of industry hype. The best case for "payback" is about 21 years. The worst case would take about 71 years for these water heaters to pay for themselves.

Pete Sessa Point well taken and thanks for bringing that out. Good article. Seems like another waste of money for most users. I won't waste my time thinking about getting one. Thank you.

[@petesessa2041]

There are a pile of of Energy Saving road baloney ploys that have been used quite successfully over the years which amount to the same kind of net losses to the consumer. Replacement windows might be the next biggest fraud. Stating with the well-worn sales pitch that they will make you house more valuable. NO! They make your house more expensive. The value of you house is determine by the person buying it...No more. No less. Using objective data, field testing and depending how much someone spent on swallowing the latest sales gobblygook, it would take years and years the same amount of time to recoup the cost of new windows. I think there is an article I read that goes over this. I think it was called "Why energy saving tips suck." There are a pile of them too.

[@penzoil11]

Pete Sessa Yeah it's amazing the money people pay for replacement windows. Vinyl siding too.

[@EurekaRecycler]

Our on demand / tank-less water heater system is messed up. This one has a recalculation pump. It seem we only get hot water when another hot water tap is open than it seems to heat water fine than after a minute the water flow completely shuts off. If I turn the hot water valve off for a minute or so it will turn on with good flow for about a minute than completely shuts off the water flow. Anyone every had this issue, and how did you fix it ? Thanks

[@rushh9005]

I want one to heat my water and my house using a water to air heat exchanger. Where can I find info on plumbing something like that set up? Thanks

[@scottnra]

Rinnai and First Company developed a hydro-air system together that works great. The tankless handles both heat and DHW and uses a priority switch to turn off the heat temporarily if the combined load gets too great. First Company makes the Air handling unit with the hot water coil in it, Contact Rinnai or your local rep for more information.

OK. We have been in this house May 2010-present 2015! ALL new appliances. We replaced one GAS instant hot water heater "Rinnaii" 2012. Then the other one in 2013. They sent us the parts we paid a plumber to install it 300.00. Now Oct 21 2015 it is leaking again. This house is only 5 years old and we have been through 3 Rinnai tankless water heaters. This is CRAP!! Do not buy one. a 5-15 year warranty? They don't even believe in their product!

Why would my external unit (V65E) come on for just a couple of seconds whenever cold water is turned off or on anywhere in the house? A plumber seems to think there is a leaking valve but all valves in house have just been replaced. Any thoughts?

[@marinecorps2791]

At 3:07. Are you serious? You didn't waste the hot water. You just didn't use as much. The water is still available. Surely you don't really think that.

[@Heffbomb]

I understood it as you're not using excess energy to heat the water to 120 when you only need 104.

[@dozendozen1238]

@@Heffbomb yes why heat all the way to 120 and cool it back to 104

[@angieeth1164]

one year on labor tells you it wont need fixing for the first year.

[@PMOwnerable]

his statement is false about setting shower to all the way hot, an just having hot come out.. every single handle shower now mixes the water so regardless you are getting cold water mixed in with the hot as well.. so you will no doubt be keeping the temperature set at 120 regardless. but still, a decent investment, but only if you have gas LP or Nat in your home.

[@charliearlieo8671]

Not true!

[@williamferguson417]

If Rinnai is such a large tankless manufacturer and produces such an amazing product why is the heat exchanger not the best in the industry? Navien has a 15 year heat exchanger compared to only 12 with the Rinnai.

[@mapquestHs]

Never again!!!!! Get one if you enjoy complicating your life! I’ll spend the whopping $25 extra in energy costs to run a NORMAL tank dead reliable hot water heater. I have wasted my time and money on several different makes and models and they all suck!!! I especially love it when the electricity goes out mid shower and the water immediately goes cold, my wife loved that one! If your going to torture yourself with one of these miserable units at least go for the standing pilot unit. I have both and at least those don’t leave you in the cold. Unfortunately I designed my hot water heater cabinet for these darn things so in order to go back to a reliable tank heater it’s a lot of work. Hopefully this reaches someone who’s on the fence about purchasing a tankless and it pushes them to go with a tank water heater.

[@scottleft3672]

[@chadmeyer9500]

1 year on labor but 5-12 years on the components that could fail and require labor to replace them? Complete bullshit. These things are a scam. And your example of supposed reliability is halfway around the world. Priceless.
