Love your channel. We’ve spent so much time watching/learning from you. I’m putting in same return system as you’ve covered in this video including same suggested pump and parts. Can my 60 ft return be 1/2 per or should it be like the main supply and be 3/4? Thank you
The further most appliance is the outdoor shower which is supplied with 1/2 copper and is 15 feet from where hot line is 3/4. I was thinking of running my return to farthest point. So if it’s 1/2 does return need be 3/4. You know what that pump flow is so you know best. Thank you for advise
the one thing I don't understand, is - using a external circulator to move the water, how do you tell the water heater to heat it, since there is no 'flow' of water turning on the unit?
Thank you so much for all the hard work you put in to all your videos they are most helpful. I'm building a laundromat. I'm going to use the Rinnai CU199IN. I'm going to have a dedicated return line. You keep mentioning the RU and RL models, will this work with the CU model?
I have a RU98i that works great but the faucet in the kitchen takes forever for hot water to get there. I want to add a pump but I do not have a dedicated return line, so I am confused as to where to install the pump. I was going to purchase the RWMKT03 . I need some guidance as to how to install it
Good stuff Mike but even better. I took your advice and bought the Dewalt cordless screwdriver. This thing has spoiled me. I didn't really think I would use it much. It's the first thing I look for now. Thank you! Oh also bought the 300mm Wera phillips.
Thanks Mike for the help you gave me. I had enough questions that he sent me his phone number and we talked through the questions! Who does that? Great guy with lots of knowledge. Keep up the great work!
Great information, well done. I have a need for this type of setup and would like to know if this equipment is "waterproof"? From what I can tell, the pump and aquastate is not, so what should I do for an outdoor setup to protect the equipment from the environment?
Mike, Thanks a million for excellent advice and the detailed video. Super helpful. Sincerely appreciate it. I have RU103en and GTK15 Grundfos pump with dedicated return line. I shall utilize the video as a guide 😊
You sir are a savant. Ty for this incredible video. Great for planning a recirc retrofit. Got the check valves, 1/8 HP SS grundfos pump, drain, shutoff valves, etc. Cant wait to get this in our ranch house and get those end bathrooms hot quick!
Couple of questions on the recirc line setup: 1. Wouldn't you need a shutoff valve on the outlet of the pump to isolate it if the pump and/or check valve go bad and start to leak? 2. Is it better to move the purge tee from the inlet to the outlet side of the pump to help eliminate air from the line all the way up to the pump?
You could add a second valve but unlike a hydronic heating system there’s not that much wster in the system so replacing a piece is very fast. The purge tee needs to go on the inlet side of the pump and check valve. I hope this helped. Mike
I kinda agree Andrew, I don't understand why you wouldn't put the purge tee between the pump and the check valve. The circ pump does have a bleed screw(i think) so you don't have to bleed after the pump. Great video though Mike, learned lots. Would like to know the reasoning on the placement of the purge before the pump.
thought about it a bit. You need a shutoff after the purge. If you put purge and shutoff after pump, you need a shutoff before pump. Need 2 shutoffs then. Might be other reasons.
That amortization is a commercial unit the Rinnai unit would be a CU199 the residential unit would be a RU199 and if you want circulation capability it would be a RUR199. I hope this helped. Mike
@@TheBuddylab Thanks Mike, I just bought the RUR199eN and moving away from Noritz..question: Do I really need the recirculation valve (part 100000663) offered by Rennai when running a dedicated line?
Sir i have a problem yesterday we miss propane and today got code 11 bipping !! What im doing with this? Not hot water at all but everytjing running as usual could ear the water pump and the control its ok except the ligth for in use is turn off!
Did you run out of propane. If so you would need to bleed out the air in the gas lines. You may also want a propane service person check the gas piping when you run low and our if propane you can draw in the liquid from the tank into the gad valve.
Help, help...for a vertical vent thru a 6/12 roof, will either roof flashing work where the 6/12 slope is the minimum slope or the maximum slope. I bought the one ( 189950 ) and it doesn't look like enough slope. What keeps the rain from leaking in on the vertical vent ?
That is a 1/12 to 6/12 pitch roof penetration. Are you replacing a metal roof boot that had B vent through it from your old water heater. Answer me in an e mail it will get to me faster. Economyplmbg@aol.com
Good evening sir, I have a RU199in that I want to install a recirculation pump. I have installed a dedicated return line. I ordered the Rinnai-R Wireless demand recirculation kit with push button and pump. After watching this video I'm wondering if it would be better to buy the pump you are recommending/using in the video, and the aquastat controller versus installing the wireless control and using the system within the heater itself. Any advise you could give would be extremely helpful! Thanks you in advance.
The system you are getting is good. Either the aqua state will turn the pump on or the push button. With the push button the pump will run less but you sill have to wait for the hot wster to circulate. I hope this helped Mike
You talk a lot about installing a tankless system in a garage, but my current tank water heater is in my basement with about a 15' vent pipe going from the tank to the outside wall on the side of my house. Can I install a tankless unit in the same area in the basement that is currently being occupied by my water tank or will venting from that far away be an issue?
No you can install it in your basement depending on the model of the Rinnsi unit you can run between 40 to 65 feet of vent. You need to minus off the length 6’ for elks Snd 3 feet for 45* You also have to see how far the vent will exit the basement
Hey Mike your videos have been very helpful to me with my two tankless Rinnais. I currently have a Rinnai RUC98i that runs on propane and want to add a return line and a recirculation pump. My last Rinnai had a ACT D'Mand pump that was button activated and it worked great. Would an ACT D'Mand SS3-200 work for my RUC98i? From my research this pump is identical to the Grundfos UPS26-99SFC.
Hey Mike! Say we remove only the pump from this setup and leave the check valves ,ball valve, drain valve . Will the dedicated return line still circulate and function properly ?
Hi, can I somehow by-laws the Circ Logic control of an external recirc pump on a dedicated return line to a RU199. I would like to control pump on/off via a smart home/Alexa plug? System would also use an aquastat to monitor recirc line temp and turn pump on/off
Mike, I installed an RU199i with a GTK15 recirculating pump for Rinnai. I am pipe the same way as shown in your video. The pump get wired into the Rinnai Control Board with the external pump harness (which I had to purchase separately). The parameters were set to 4B (dedicated return line)and 5A (comfort). The pump is running but not heating the water in the loop. The pump stops running after a couple minutes. I talked to Rinnai a couple of times and I'm getting conflicting answers. One said I need a MC-195T-US the other said I didn't since the GTK15 has a dial timer and it is wired into the main Rinnai Control Board. This is very frustrating!! Can you explain how this needs to be wired? My mistake for not just going with the set up in this video.
Hi RG; 1) Replacing Navien 180P which has a dedicated recirculation line. 2) Installing a Rinnai RU160I + sensei. 3) Removing the Navien (2 wire) circulation pump and integrating it to the recirculation line like your video shows. 4) page 63 of the ru160 installion manual shows to connect the 2 navien pump leads to the pc board. 5) Is that all I need to do for the recirc to work? 6) Can i assume that the sensei does the rest, water temp + on / off? 7) And I do not need the "control R module" ?
awesome teach thank you....you the man
Thanks
Thanks for your help! This doubled the cost of my WH install, but it will be worth it! No more waiting and wasting water.

3/4" is the best, a Rinnai will flow the best with that size pipe
I respect your statement about Grundfos
Industrial quality home use should never be understated.
The further most appliance is the outdoor shower which is supplied with 1/2 copper and is 15 feet from where hot line is 3/4. I was thinking of running my return to farthest point. So if it’s 1/2 does return need be 3/4. You know what that pump flow is so you know best. Thank you for advise
It should be all 3/4" a Rinnai will flow through 300 feet at 4.5 and a Navien will flow 600 feet at 5.0
the one thing I don't understand, is - using a external circulator to move the water, how do you tell the water heater to heat it, since there is no 'flow' of water turning on the unit?
Dude, you are friggin' awesome stay safe & keep up the great work

Another very informative video and a great job on having everything planned ahead of time, no editing required. Hello from Idaho
Thank you very much. Mike
Just the video I wanted to watch, thank you. Can I do this with a 2007 Rinnai R85 model with a home recirc line?
Do i need a check valve if i don't have a pump or dedicated return line????

I’m glad you like it. Thanks for the comment
Can you do a Video on how to properly wire the electrical for the external recur pump, also any type of dip switches that have to be rearranged.
that will be coming up in a few weeks
@@ThatTanklessGuy Great, I always my electricians wiring it wrong lol
isn't that what he just showed

E mail me the model number of the unit. If it’s a RL series unit you can use the HE Plus pump kit.

Hi Mike, great videos. Even though u live down south, I was wondering if at some point u would be posting a install on a Rinnai combo unit.
Yes I will, I’m waiting on a combo unit to be delivered to me. Mike

so what actually tells the water heater to come

Have you done the math on how much propane the rur199ip burns on the comfort mode?
why stainless steel pump as opposed to cast iron?
