2 years ago I put in a rinnai combo boiler in my house in Ohio as a DIY (I'm not you average diyer) it replaced my old hot water tank and my 50 year old boiler both using expensive propane. I'm using 30 to 40% less propane and its off the floor on the wall
The tiny footprint when compared to a boiler AND a tank water heater is so impressive to me, it really is a great machine...have you been enjoying it more, are there things about it you don't like?
You mentioned the thermostat for the floor heater. Just to confirm you can set the temperature for your radiant floor heating and your hot water separately ?
Bought a house with an old boiler and water heater. Been considering several different options including getting off hydronic heating. This sold me on the combi though. Still gonna put in a wood stove or something as a secondary, but man, this is 🔥🔥🔥
The hot water has been great. This is the first winter with it but it's been keeping up with heating demand just fine. I'm still awaiting the first gas bill with a full heating demand to see the cost savings. I really like how the Alta models have built in outdoor reset and also the firing rate is modular automatically.
@@RogerWakefield long island, NY. We normally get temperatures in the teens here in January so the worst is yet to come. I'll provide an update on how my system fares once the real demand kicks in.
I’m saying be careful what you install. The last thing you want to do is spend 1000s and end up with something that won’t do the job you need. I’m not sure of boiler models in the states but here in the uk we have storage combi….this is a combi boiler with a tank inside also. This would give you up to 22ltr per minute of hot water over multiple hot water draw offs Heating side you should try to pick something that can be range rated…this means you can adjust the kw of the appliance to suit your homes heat loss. This will save you money on fuel I know Viessmann are in the states, maybe look into a 111w or a 222f.
When you talk to a customer about saving $$ they should also be informed of the payback period. Here in New England we are finding that it may take over 20 years to offset the cost of the unit + installation. Unfortunately most of these new technology units don’t last more than 15 years. If the customer wants to be “Green” that may be the more compelling fact.
This Rinnai seems very similar to the infamous Navien units... same heat exchanger that constantly leaks and same electronics just enclosed i think... i hope that from a brand like Rinnai we have a better InProduction product testing for safety and others.
got a bid requested from a contractor who the customer had put in a mini split heat pump, and wanted a bid to get rid of the Navien combi boiler, and replace it with a domestic water heater, and abandon the floor heat. I told them to get a powervent instead of an electric, and they could just drop the pressure on the gas line, and reuse the flue and plug in power supply.
Can I fill a bathtub with hot water using this? Summer or winter? Can you wash clothes and fill a sink at the same time? Water pressure vary all the time?
Bath tubs are unrestricted. Fill a 5 gallon bucket for 30 seconds then double it. It will raise water temp 70 deg f. So your cold water is 50f it will make it 120f. And if you got 4 gallon from tub hot water only. Then yes it will work.
@@backwoodshomesteadllc Not ready to risk a miserable outcome at this scale. Spending several thousand dollars only to find inadequate temperature, quantity or pressure would be... A catastrophe! I mean, what's the fix if it doesn't work out? Add to the system, replace it or just live with its shortcomings? Sticking with 82% efficiency of a tried & true system is my final decision. Scheduled for cast iron Peerless install next week...
@@John_Lee_ Thanks for the input. Still pretty ignorant about the tankless systems. Point is moot anyway. 65 year old water boiler was replaced by a simple, Peerless MI-04, at a "reasonable" price.
That's just Crazy. We have them installed in Europe (I'm italian) since the eighties. It's the most common thing in the world. Now we're looking to replace them with big, heavy, complex hydronic heat pump plants which cost four times more. Poor Europe.
Question, what kind of work would this actually take to install? New water lines across the house, heat exchangers/exhausts? Would they work well, or better, with a an AC unit, swamp cooler, and/or heat pump?
Great for HWS and very good for radiater / underfloor heating. 22mm flow and return and you will be cooking . 22mm gas line also .iv'e been fitting for over 35 years in GB and Europe. Best make this side is Valiant or Potterton. Really easy to mantain also
This is a perfect post! I have a good friend of mine that is actually in the market for a new boiler. I shared the link to this video with them. Thank you, Roger! **
We put in a combi heater/hot water Rinnai I120N 1 1/2 years ago, but keep having pressure issues. The error E430 keeps showing & we have to release the valve to increase the PSI to 25. This works for a few days & error comes back. Do you have a solution for us?
I been watching your videos in the past week . Learning how to learn a clogged sink . I snake it I try some other stuff like using a hand pump to pump out some dust and dirty water . Took me 4 days but I been learning . Can u make a video bioOne vs bio clean vs grease x . I know it wouldnt help much but just to clean my pipes etc.
After endless trouble with a renai tankless hot water heater I don't even want to look at it. Literally it's been that bad. The plumber who put it in can't fix it so I think I am stuck doing it myself.
What trouble have you been having? I'm not saying it isn't giving you problems...but a lot of plumbers are scared to install and repair tankless water heaters becasue they don't know enough about them...hopefully someone gets it working for you.
@@RogerWakefield I live in a remote area so I fix everything. I was a master electrician and plumber so I got it figured out. But the plumber that built this mess is a moron. 75 lbs pressure in the mechanical room 20 on the main level. He necked down the pipe to pex 1/2" and it reduced flow so much that the flow switch won't trigger the renai to fire
@@RogerWakefield So I get to yank in New pipe. But the renai is not a good choice because it's only a 1/2" supply and discharge so in a 3 level dwelling it's inadequate. It should have been installed upstairs if it had a chance of working. I will get pissed and tear it out and stick a conventional water heater in most likely. It has a plastic exhaust pipe so I will have to change all that as well.
@@RogerWakefield it's half and designed that way. Must be the smallest one they make. The general contractor did a great job building this place but this plumber is not a good one. He never completed the job and tried to double bill me for stuff he did that was trash. Lol I said you don't send a bill almost two years after the CO and think your going to get paid. He tried to bill for outside hydrants he never installed. I won't call him back in for warranty work because he did such terrible work. I'm 68 years old but I still can do the work. I did a lot of controls and industrial plc type work so I do understand it pretty well he is just a plumber cutting corners
Roger what happened? I thought you said I wouldn't see the Fabuloso jars in the back anymore. For shame Roger's lol. This is a really cool device. I would want it but I'm in Phoenix and it doesn't get cold enough.
Tankless water heaters are expensive! They will not save you money. They will cost you $6,500 more over 15 years than a conventional water heater. And a combi boiler in Texas is just insane . I enjoy installing these things but I won’t lie to people in order to make money.
I got a 20yr old propane boiler with a 120gal indirect heat tank. 6k square foot house, Three zones heated floors, five full baths. For the biggest 199k btu combi boiler that can handle it all. What should I expect to pay in your area?
Yes that is true. Cast iron boilers can last up to 50 years. It’s one of the reasons I have yet to make the jump. To get a combo installed in WI, it’ll cost about $17,000.
“Combi” refers to combination boiler that provides domestic hot water and heat, vs a solo that provides heat only. It is not a combination of boiler and tankless water heater.
My new house is waaay over budget; I'll take the middle grade. the house is super efficient anyhow; 12" thick walls. After the rebate I will be paying about $600 to heat my radiant floors and my hot water, for at least 12 years (warranty). And for $600, if it lasts 12 years, I'm happy. I can replace it with a 'better' one when I actually have some funny money again.

I put a lochinvar in my house in 2019 switched from oil to gas, saved tons of money
You mentioned the thermostat for the floor heater. Just to confirm you can set the temperature for your radiant floor heating and your hot water separately ?
Rinnai needs to make a pool heater😊
You may be able to use ru199 it is stainless but i would ask first
Bought a house with an old boiler and water heater. Been considering several different options including getting off hydronic heating. This sold me on the combi though. Still gonna put in a wood stove or something as a secondary, but man, this is 🔥🔥🔥
I ripped out my old oil boiler and all the stupid pipes and baseboards..and put in a heat pump ..best decision I made 🫡
I ended up putting in a Alta condensing boiler with 2 zones for heat and another zone for a t23 turbomax indirect tank
Cool...how has it been for you so far?
The hot water has been great. This is the first winter with it but it's been keeping up with heating demand just fine.

Sounds great 👍
Combi boilers are good but it depends on your hot water requirements. If you have over two mixer showers then it’s not going to suffice
so are you saying 2 showers cant be running at once? my on demand is needing to be replaced and this would be nice to also heat my basement

Just checked…222f is available in the USA
Lmao yeah heated floors in texas like they need that! Maybe cooled floors.

@@0rnery The answer is to get a heat only condensing boiler and have one zone feed an indirect tank

is this i120CN ? does it work with hot water baseboard and also replacing hot water tank like 2 in 1 ( Gas boiler and Hot water tank boiler )

We are just about done building a barn to minium I have a 5000 square-foot shop which boiler do you recommend to heat the floor only
I’m looking into putting in a new boiler system. Thank you for the information and I love your RUclips videos.
Thats awesome! What units have you been looking at?

I am getting one installed today. Can't wait to take long hot bubble baths again
That's awesome
Is there any way we can show the connection pipes on the bottom of the tankless water heater?
Google's your friend. Rinnai has a website, like every other company in the free world.

Sounds like you have water leaking from somewhere in the system.

Rinnai is the best. Made in Georgia. Much better than #Navien.
Alta condensing boilers are made in PA
I saw you at the Skills USA Nationals today. I was in the electrical construction wiring competition
Should’ve said hi!
Can it be electric instead of gas?
I'm not sure if Rinnai makes an electric combi boiler, that is something you may have to do research on.

DO ANY ELECTRIC TANKLESS COMBI UNITS EXIST
This is what they use in Mexico.

Sadly the only last 15-20 year vs cast a iron boiler 30-40 + years
The reliability of the Rinnai combo boiler is unmatched
@RogerWakefield Says the man getting paid to say that lol
Yes that is true. Cast iron boilers can last up to 50 years. It’s one of the reasons I have yet to make the jump. To get a combo installed in WI, it’ll cost about $17,000.
What? Maybe you should explain COMBI first. 😅😂😊
“Combi” refers to combination boiler that provides domestic hot water and heat, vs a solo that provides heat only. It is not a combination of boiler and tankless water heater.
Every one in uk have combi boilers and apparently they are the cheapest to.
St. Joseph Pillar of families pray for us
This guy talks for 8 minutes what should only take about 45 seconds to explain.
Rinnai is no where near the top …. Middle grade at best
What is at the top? In your opinion?
Yes pls tell us.
Noritz
My new house is waaay over budget; I'll take the middle grade. the house is super efficient anyhow; 12" thick walls. After the rebate I will be paying about $600 to heat my radiant floors and my hot water, for at least 12 years (warranty). And for $600, if it lasts 12 years, I'm happy. I can replace it with a 'better' one when I actually have some funny money again.
Will this control the zone system for the in floor/baseboard heat as well?
