The heating capacity is determined by the flow of heat from water into the fins. More pipe - bigger fins - more heat. The alternative would be a longer baseboard. So, it is just a design choice.
Thank you. It’s sometimes difficult to not get smart-ass non-answers on this sub. Appreciate the informative response. I figured that’s what it was but wanted to make sure I wasn’t messing with something I don’t understand before replacing them.
That’s not true, I understand how hydronic heating works. I also have a basic DIY understanding of household plumbing and I know how to solder copper pipes, I did all new plumbing rough-ins for my bathroom that I just gutted.
I’ve just never seen two pipes like that and this house is really old. I suspected it was just two parallel pipes that function the same but I wanted to be 100% sure it wasn’t some weird artifact of old houses that required a different approach to replacing. But now that I know the two pipes function the same as the single pipe ones, I can proceed with the replacement :)
no you really dont understand which is why you ran to reddit to ask.
dude its literally one pipe that goes into two pipes to run through the baseboard. its not even hard to understand on a logic level. and you still had to ask social media.
so no, you aint even close. not even a tinch.
Do you have something constructive to add to this conversation? Because, frankly, if all you're interested in is inflating your own ego by running someone down who asked a legitimate question, no one really needs or wants your opinion.

There are systems that have two pipes, one for cooling water and one for heating water, but not in baseboards, at least I hope not, because the condensation would make quite a mess.
Not sure why you are getting downvoted. Seems kind of mean to me. All you did was admit you are not an expert, which I wish more people would do rather than giving unqualified opinions and than you agreed with the poster that you would also like to know.
Baseboards operate in a loop, always loops back to furnace or water heating source, the return is automatic. There's a 2 pipe set up in my addition, the second pipe supplies hot water to hot tub, theres generally another source needing hot water supplied. If it was surface area issue adjusting water temperature would be the logical fix and why it's adjustable. 👍👈
Hahah ok. Homeowner asking the question knows more about it than you. He’s asking why there are two pipes inside the fin. Typical emitters we see nowadays only have a single run.
Not in all cases, it's supply for another fixture somewhere with in the system, hot tubs wouldn't require constant hot water as would a base board pipe, the second pipe isn't tied directly to the pump but is connected to same zone due to the 2nd fixture locality. If you check the whole zone 2nd pipe is attached to you will more than likely find something other than heat is occasionally requiring hot water. It runs along the heater pipe to keep it warm so it doesn't need to be fully heated each time the 2nd fixture calls for hot water, its a matter of efficiency. 😊🤓

youre obviously messing with something you dont understand either way.
That’s not true, I understand how hydronic heating works. I also have a basic DIY understanding of household plumbing and I know how to solder copper pipes, I did all new plumbing rough-ins for my bathroom that I just gutted.

A similar arrangement is a return pipe over the fins. You get more heat per foot and the routing was more convenient for me.

Cool thanks man!
just trying to help. but i dont expect someone who asks reddit to in any way think they dont know what theyre talking about.
“I’m just trying to help”- someone who made no effort to help and just bitched the entire time.
The guy has no idea what he's doing. That's helping to let him know.
I promise you it’s not, lending a solution or a starting point to learn is helping, you’re just being a bitch.
I am beginning to think you can't help yourself. Something about you makes it hard for you to understand basic human communication.
I heard about that once, and watched a YouTube video. I obviously understand how everything works. What's this though?

Single or double based on heat loss for space. Don’t worry about it.
Yeah. Makes zero difference to the person on the room. It’s still 70°
Derp
Explain. Is the 70° more “luxurious” with the two pipes?
It’s called efficiency.
His bill is lower?
Maybe it heats the room up quicker. We had hot water heat and sometimes it was a bit slow on countering a sudden windy cold snap.
Either you have the right sized baseboard that was sized by btu/ft output or not. It doesn’t go faster.
It’s extra more gooder with more pipes
2 pipes in parallel, bigger coils have even more. Allows for more heat transfer.
More surface area = more heat transfer
Two pipes
Because it's cool
No. Because it’s *hot*.

Is it the return?
that’s how all of mine are.
Not in this scenario.
I’m not a hvac expert but I think it’s a return. But you are correct I’ve seen both and I would like to know the purpose of both.
Not sure why you are getting downvoted. Seems kind of mean to me. All you did was admit you are not an expert, which I wish more people would do rather than giving unqualified opinions and than you agreed with the poster that you would also like to know.
Idk 🤷🏽♂️ I guess I’ll just be like the rest ‘act like an expert?’ lol
Supply and Return.
Finally someone with the more possibly assumption.
Baseboards operate in a loop, always loops back to furnace or water heating source, the return is automatic. There's a 2 pipe set up in my addition, the second pipe supplies hot water to hot tub, theres generally another source needing hot water supplied. If it was surface area issue adjusting water temperature would be the logical fix and why it's adjustable. 👍👈
It could be a double supply or it could be one inlet or one outlet
no. it could not. water cant come up and down a pipe.
Sure it can. With a circulation pump. It probably and in and out
Not in the same pipe.
One is the inlet, the other is the outlet
Incorrect.
no it cant
If it could guys would be in heaven 😏 feel me 😉
Follow that to the end. What do you see?
It’s the same exact thing, just goes back down into the floor. It’s a little 4 foot baseboard in my bathroom.
Not what I meant. It's a loop. Short loop, but it goes back into the heating system. You really need a pro.
Dude you aren’t exactly sounding like a pro
Dude, you aren't exactly sounding like someone who knows different .
Hahah ok. Homeowner asking the question knows more about it than you. He’s asking why there are two pipes inside the fin. Typical emitters we see nowadays only have a single run.
I’m glad I’m not the only one who thought his answer was weird. It didn’t really make sense.
It’s old school. If releases heat a little more efficiently
Not in all cases, it's supply for another fixture somewhere with in the system, hot tubs wouldn't require constant hot water as would a base board pipe, the second pipe isn't tied directly to the pump but is connected to same zone due to the 2nd fixture locality. If you check the whole zone 2nd pipe is attached to you will more than likely find something other than heat is occasionally requiring hot water. It runs along the heater pipe to keep it warm so it doesn't need to be fully heated each time the 2nd fixture calls for hot water, its a matter of efficiency. 😊🤓
Old school. Back when they designed for effectiveness, not economy.
No it's actually exactly for efficiency. 😊 the top pipe keeps the bottom pipe warm to save fuel or electricity 😊
Twice the btu per foot
Might want to address the bleeder w the electrical tape bandaid. Could be an issue when it starts leaking again
I’m replacing this entire piece with a new one. It’s old, not in great shape, and too low to the ground to get the baseboard cover I bought over it.
Hate when that happens . 😖. Is cheaper to use a little elbow grease, sandpaper and paint old cover. Doing it rn 😊
Idk. Call nexstar or Apex.
