Just bought a house built in 57. Removed a wall and upgrading from radiators to baseboard. Have 1” main supply lines with 1/2” monoflo tees that fed the radiator. I was going to re-use the existing lines but the 30 seconds of this video just saved me. I’ll use elbows for the baseboard to use 100% of the water flow.
youtube needs more videos like yours. pure information. every angle possible in 9 mins
Louis, I cant thank you enough for this vid. Years ago, I converted my system from exactly what you drew up here and had this very same problem. The boiler was always running and the basement, was just as warm as the living level. This past weekend, I remove all the monoflow tee's and extra piping, took out all the 1/2 pipe and replaced it all with 3/4. I gave every baseboard an elbow and the change is dramatic. From the bottom of my heart and wallet, Thank You!
Just a few short sentences. YOU hit the nail on the head for the issues I have for an old mono flow system and then some. No other youtube video that I could find came close. a billion thanks!!
+jj jj - One more positive comment - I like how you present the information in the video. Cool, calm, collective and easy going while I seen many other videos where the presenter looks like they got a pipe up their butt and their presentation is very rigid and boring. Excellent job!
I've been struggling with this issue ever since I bought this house. After watching your video I investigated following your instructions and found that I had BOTH of your first two scenarios. That is exactly what they did. They installed baseboard heat with Ts in the line allowing 90 percent of the water to just bypass it AND they put air bleeds in the wrong ends of most of them... Thank you, I've been struggling with this issue for seven years.
Same situation in my new house. Please could you let me know if they had to cut open the dry wall and what is cost you to correct the problem? Just the the bed room in the lower level is always cold. I haven't checked if it has the Ts
In my house they go straight down through the hardwood floor. None of mine have anything to do with the walls other than leaning up against them for mounting.
Likely you need a air purger and Extrol tank. Extrol is type of expansion tank.
I know zero about plumbing boilers whatnot but was wondering why some of my heaters were hot and some were not. I now have a much better understanding of how this works. Thank you so much! This is the most straightforward HELPFUL videos I’ve ever seen.
Wow finally someone that knows what he's talking about.
omfg! we have been going through 300-400$ every month during the winter. we have base boards and none of them are even warm to the touch. thank u so much for this video been researching on my own since my landlord isnt the best handyman
During renovations, a contractor put a new baseboard heater in my small bathroom on the top floor. When it was time to turn on the heat, there was nothing. I was able to bleed enough air out to clear half of the lowest level of the house and the living area. Nothing upstairs.
I called the contractor who just kept promising to send "his" plumber. I called my oil burner man who spent at least an hour trying to find a bleeder on one of the baseboard heaters upstairs. No luck.
Then I found your video. I warily went to the burner, closed the valve you described and ran the water into my sump pump. That evening I noticed how warm it was upstairs. Thank you so much.
I had no idea why my system was running like garbage. This video helped alot. Thanks!
This is the best video on baseboard heat I've seen. It explains my problem exactly. Unfortunately, i can't get to most my baseboard so I think I'm stuck with the mono flow t's. Thanks for the video.
Wow, can't believe you explained exactly what is happening in a property we just purchased. (1) section of heat was ice cold, bleed lines, added bleeder above cold section and it got hot, downside, another section of heat went cold. Added bleeders to (2) other base boards on main floor (there is no basement). Now original cold goes in hot but feels cold in fins and is cold in return. 2nd floor is warmer than 1st, so we considered adding a reducer to 2nd floor, then considered added another pump to cold section to push water thru.... would love to hear your thoughts :)
Thanks for posting. I understand whats wrong with my system now
You da man. I have been having issues in my old home. All the radiators are nice and hot but there are a few rooms that have base board that only get warm and this video explains why. Thanks!
Great video! Informative! Thank you so much! I have been trying to figure out why my kids hot water radiator is cold every next year for 3 years. No plumber I hired could figure it out. You’re a real professional plumber. Wish you were in New York.
Thanks. I’ve had three different plumbers check out my system and none of them could tell me why I don’t have heat. Also the last guy didn’t purge the system after replacing a broken valve. All my two inch lines are hot from the mono tees up they are cold. This is turning into a nightmare. I took a metal straw and blew air into one of the bleeder valves hoping it would pull a prime when it blew back out. It did end up pulling hot water up from the mono tee but only for 10-15 seconds. I have been tinkering with this system and watching videos all day. I wish I had found this one sooner. Thanks again. Plumber #4 will be over Monday.
Good explanation... I don't know why anyone would dislike this video.
only people that are losing money due to his free advice.
Thank you so much for sharing your knowledge, Louis!
Great piece of tutorial!
I felt like we were about to go look at a job together after this. Good stuff
This is a fantastic video! Superb! Not only what but why and how. Spectacular job.
Great explanation! Straight to the point. Thanks!
Thank you for this video, the first reason you explained is what I’m dealing with at my grand moms house. It’s an old house and it has the mono flow tees feeding each radiator, I replaced two sections that weren’t getting hot because I thought they were clogged because there 65years old and thought maybe there clogged. Me being inexperienced I put baseboard tees with bleeders on the leaving lines of the baseboard and one of the sections isn’t getting hot. I bled the shit out of it with no barely any result. The leaving line with the bleeder was starting to get warm but the entering line was cold. I’m going to put a valve in the return line to force it through that section, that’s my cheapest option. I really appreciate your video because I was starting to feel defeated. I even soldered in a drain valve before the boiler on the return line to try and purge it out that way and same result.
Great video, easy to understand and now I have some knowledge when I call a plumber to bleed my baseboards Thanks
Best explanation East coast style,you rock!!
Etsy Bravo Greek! Nice Explanation helping people to solve some very perplexing and annoying problems!
Love your accent! Knowledgeable!
Wow, thank you!
this guy saved me a headache. my baseboards have T fittings
I will give you this....Great Video and lecture..............If someone can't understand the dynamics and principles of this video....LEAVE IT ALONE AND CALL a PRO! It really helped!
Hello Mr. old school, you sure know your business! 👍
Boy, did I learn a lot from your presentation! Thank you so much for doing this. Good job.
I used the valve solution on the header after customer installed his own baseboard to replace convectors. How many times I seen plumber? put blenders on the wrong side, your right, no bleders, just purge manifold. Too the point, excellent easy to grasp explanations
Thanks Lou... I've learned that I don't know what I'm doing! I have successfully run baseboard on monoflo tees, AND put bleeders on the downstream elbows to bleed air. Guess what? NO CALLBACKS!
Look at the difference between 1 GPM and 4 GPM ratings on baseboard... not much, is there? so, add an extra foot or two of baseboard then!
If you need more flow, use TWO monoflo, one in reverse at the other end... plenty of flow then! Let's you use TRV to control room temp without zone valves!
Thanks for breaking it down “shotgun “ style,..video helped me a lot
About to be 2019 and still this video helped me out so much 💯
2021 video still works
Had one baseboard not hot off mono flow tees, I thought the tee was gunked up but this makes sense it is the longest run of baseboard and the hot water would rather run by it than go through it going to need to cut open a nice finished ceiling to put a valve in
I have a total of 5 cast iron baseboards on my first floor. The first three of them (in water flow direction) are about 80 to90 degrees colder than the last two according to an infrared thermometer. I definitely have the T connections and always thought it seemed kinda weird for the water to flow both into and past the heaters at the same time. I cant wait til the weather warms up so I can fix those suckers. Thank you
grumpchong with cast iron baseboard you wouldn't want to direct Loop them the last cast iron baseboard would not get water hot enough to sufficiently do its Duty. this is why you have monoflow tees so that every piece of cast iron radiation gets hot water at the same time and sufficient hot water
Thanks so much. Very comprehensive. You’ve helped me understand my system.
Wow you sure know your stuff! Hoping that our basement bedroom will finally be warm after we correct the problem.
Thank you, I appreciate this information. Nicely explained.
You mentioned the one thing I needed to purge the system and the is to turn off the value in front of the purge valve, of course , that makes sense, 50000 gals later. Lol. I still have a zone making a little noise but I'll live with it for now. Thx
Thanks a lot i made the mistake , fixed it with some 90 elbows ... Thank you
What about multiple zones , you need a bleeder on the return at the boiler before the valve but you also need one on each individual heating zone ...
Just like the guy before me said good vidio right to the point and very informative thanks
i have baseboard on two floors, i added a vent on the top floor not a bleeder a small key vent at the highest point, it works great,i open and close as needed.
If you have a mono flow system or a system pipes in series, either way, the radiators at the end of the loop will output less btus. The biggest problem with monoflow is when you should use one or two mono flow t’s AND t spacing. If the t’s are spacing is too close, the water will not flow through the baseboard. Rules need to be followed.
Dude, well done... I know S*&t about plumbing but you explained this perfectly!
Lou, I really appreciate your videos! They are no-nonsense and get right to bottom line. I was wondering if you might be able to answer a question? My sisters house has a NG boiler with 4 zones and aluminum fin baseboards. The plumbing is 3/4" copper. I am wondering how the system would work if I was to swap the current aluminum fin baseboards for cast iron baseboards? I am not a heating expert by any means, but every house that I have seen with cast Iron baseboards used a mono-flow loop. I have never seen a house that used cast iron radiators with a full-flow plumbing configuration. My sisters house is plenty warm, but the cast iron baseboards have so much more thermo-mass and store the heat after the boiler turns off. Any thoughts that you have would be much appreciated.
Excellent video
⭐️⭐️⭐️⭐️⭐️
EXCELLENT THANKS BROTHER
What about three levels townhouse sharing the boiler...what I find is the second floor, living room dining room, gets so cold...there is rarely heat in the baseboard. But the third floor, bedrooms, gets the heat. Also the second floor has the longest baseboard dimension.
In under 10 min you saved me a hour watching 15 other guys getting fractions of the info I needed at a time. The thumbnail was just another instructional in appearance. Then the video started and I seen the mustache! I knew this was the video I was looking for. A man with a beard (which includes myself) being a sign of experience, patience, dedication, and masculinity has been so diluted by all these hipsters, yuppies of my era, and just lazy bastards who find its too much effort to shave. While the beard has been taken down multiple levels, the mustache remains solidified! there is power on the upper lip brother! My only suggestion is on your thumbnails stache forward! And thanks again for the great info without the b.s.
Really great. Thanks. I was thinking of three bleeders, though. One on the supply one on the return and one in the middle
great explanation and information on mono flow system . tks
Exactly what I was looking for.
Straight to the point very helpful. I tried putting in a valve between the monoflow tees too see of it would fix the problem. It def gave more heat to that pipe but it still wont go up to the baseboard on the second floor any ideas
Dude..... great video.
Thank you Sir. Great video and very helpful and informative
Excellent video Thanks' Master!!!
Fantastic video. Thanks Lou!
Sounds like a male version of Mona Lisa Vito in My Cousin Vinny!!
Nice, clear explanation. Thanks!
what a great video, good clear explanations, I'm subscribing
very informative thank you.

Hello. I have a 1 zone system. Old "mono-flow" valves. Boiler in basement. Pipe go out of boiler and splits in 2 at first radiator, then returns. (All radiators on first floor). 14 years ago, we replace whole heater system, from 1947. The plumber installed a second pump on the return right before the boiler. The outlet has a pump right at top of heater. That stopped working a few years ago. I never bothered to put in a replacement (Taco) until now because 1) it's summer , so I can work on it, and 2) the first baseboard hasn't been working. There is bleeder valve but only on the return back end of the mono-flow valve. And I believe that maybe that baseboard isn't working because there isn't enough pressure to get the water fully through because the outlet pump isn't working. Another thought is that there might be resistance at the non-working pump too slowing down water to get thru the radiator. Any thought about this??? Thank you
Thanks for the explanation boss. ^_^
You are great at explaining. Thank you so much for the information. Very helpful.
I will never say “radiator” the same again
My dad ran baseboard with mono flo Ts …….had a valve in each room to adjust water flo …….never had a problem……if you run pipe straight thruogh…first rooms will get hot each room that follows less hot last room will be cold…..where you put the stat ? First room - last room cold……last room - first room hot…….straight runs cheapest way to do it ….mono flo most expensive in time and material …but the right way in my book…
With mono flos one could also put a stat and control valves in each room…….or one could run separate zones to each room……even more time and material. …but probably the best way in terms of heat in each room……
Louis, thanks for the video. It was very informative. I wanted to ask how do I add a purge to my boilder. Please provide different options/brands of devices needed.
Thanks for information- however, boiler was serviced by gas company but there is no water flow through the pipes.
Very good information
Great video- a BIG help.
Thankyou for this video. It helps to know a little bit when I fork out money to the furness guy:))
We purged the system and replaced a few parts and now heat doesn't reach all rooms.
Wow I could have written this. Did you find the cause?
This video was precious to me because it touches on two issues I'm having with a basement radiator! I turned the basement radiator around so that the bleeder valve is now on the outlet side of the radiator and happily the radiator at least fills up with water. However, it still doesn't get hot. I'm considering installing mono-flow tees to help get the hot water flowing to the branch that this particular radiator is on. However, I have a two pipe system. Do mono flow tees work on two pipe systems? That's my question. Many thanks!
can you add zone valves to direct water through different t-valves to fix the problem?
that was awesome. Thank you!
Great explanation Lou. Do you have any advice for me? I am home owner, not a plumber. I recently got a used indirect water heater tank removed the thermostatic control and pump and tab into the return of my baseboard heating system return to preheat the domestic water before sending it to the electric water heater. I live in the country and oil is the source of energy for my heating system.
thank you
Thanks. Looks like I am gonna be putting a shut off valve on the main line for the room that always stays cold
very informative, thank you...
That's probably whats going on my bathroom...very little heat coming out of baseboard. Damn plumber
Bleed the air out of the system
Not all my baseboards are getting hot. My second floor ones are doing great but my first floor does not reach the desired amount of heat. It's always cold on my first floor.
I dont have a basement im on a concrete slab , i don't know if that makes a difference.
Can you bleed the boiler with the circulating pump is on?
I guarantee that the 55+ thumbs down are plumbers who love and did the shortcut plumbing of what you are explaining to fix......lol
hay louise you video is very helpful my friend never get his baseboard hot as other ones I checked it for him after bleeding by the boiler & increasing pressure it worked for 1 day same problem again what could be causing his baseboard not giving enough heat can u help
Is it better to installed the circulator pump on the supply line than the return line.? My boiler is 50 year's old.
Great video! Thanks! Just like you said, baseboards were installed with the mono-flow tees still in place, which I will replace with elbows, however is it okay that a mono-flow tee with radiator comes right after the baseboard and elbow on the same line? Thanks!!
If we have multiple baseboard still we gone follow same roll???
Sounds like an old gravity system Dan, not very efficient but very expensive to update to a new system if you don't have an extre $9000.00 leave it alone. They do work. Just heats an awful amount of water
Would you say monoflow setup feeding baseboard increases head pressure? Or rather you should consider that it increases head pressure for pump sizing. Having an issue and I’ve tried to increase water pressure and nothing. I have baseboard that is warm and a radiator that is cold. I think the baseboard is a path if least resistance and the radiator needs more pressure to get the hot water to flow through. The system worked with a old B&G 100 but nit with a Taco 007
I came across your video and the house that I bought has a finished basement with two zones. Many of the baseboard heaters are hot to the touch. In one room it's cold. I probably have a leak, but it will be difficult to locate the leak when you have a finished basement. How would you tackle looking for a leak in this case? Thanks
What about on a 2 pipe system? Has a separate return. A house has old finned type heaters all over the house. I am replacing one in a small bathroom with a new 3 ft unit. 3/4" copper with fins. All heaters are fed with mono flow tees and all heat well. They all return on separate pipe. Seems this is an ok way to use mono flow tees with finned heaters.
Another problem is a heater on the 2nd floor, there is no water reaching the heater. Once I replace the heater in the 1st floor bath, I am going to bleed the entire system at the boiler. Does this sound like a proper approach?
it could also be a faulty motorized valve.
I have an older home and its a two family. the basement and the first floor get heat but certain rooms on the second don't. what should be my first plan of action. thanks
exactly what happened to mine where my handyman just cut the line and replaced it with baseboard to my 2nd floor dormer and it gets no heat. tried to bleed the system for 2 3 hrs to no avail
Thanks.
thank you, my 90 yr old mom is freezing! tytyty, but can we reduce to half inch w/o decreasing btus on down the line?
My house wasn't converted but, the problem I have is the baseboard in the living room and basement doesn't get that hot, you can keep your hand on it, the bedrooms and bathrooms, even the one in the basement get hot, you cant touch them, I cant figure it out, replaced circulator, tank, purged it to death, the only thing I can think of is that the living room and basement are the last spots before the water returns to the boiler, any ideas?
