“There are 3 kinds of pipe. There’s what you have, which is garbage. There’s brass, which is fine, unless there’s a problem- THERE’S…
“…ALWAYS A PROBLEM. And then… there’s copper. Which is the only pipe I use. It costs money. It costs money because it saves money!”
StillNotYouTube
Yeah, for something that is going to be behind a wall and inaccessible for the life of the building, I'll take copper.
zFUBARz
This isn't behind a wall though.
It probably does at some point though. It looks like they are using some kind of conduit, which would help, but that is not typical.

I love that there are valves for each water line to empty it easily and individually, and also that there's an extra pipe each just in case!

This looks nice, but as a former new construction plumber, this will fuck with both your water pressure and the time to get hot water.
eidolways
What're your thoughts on Gary Klein's suggestion to use trunk-and-branch with a 3/4" recirculated loop with 1/2" line to individual faucets?
As far as my experience goes, that's the only way to do it/what I was taught. Gives good pressure to each appliance when it's ran like that.

driving it up the wall too

The right-most white pipe has its valve open. When they turn the water on, it's gonna drive water up the wall.

Okay, but imagine the horrors of waiting for hot water for SEVERAL SECONDS!
redsmerf
....It takes about 2 minutes in my bathroom to clear the cooled water from the pipes and get hot water in.
JacktheKind
true, The don't have the heat loss of the tank, but instead distributed it over all the pipe surface... which seems worse
RatsLiveOnNoEvilStar
Wouldn't it be the same heat loss over the pipe surface if it was a tank system? Water still hast to get there, or are you refering to just
the white line, in which case, whatever heat it still has above the initial intake will still save on keeping the red line to temp right?

Cold water, hot water and return of hot water (the white) with pump so you dont wait to get hot water.

As others mentioned above its more likely a recirculating line for potable hw. It's a very bad idea to mix hw for heating w/ potable water.
In most places code explicitly sates that you need to have separate heaters for hydronic heating and potable hw.
Mazzy94
A return line from the hots.wastes energy but means rich people don't need to wait long for hot water
Filanwizard
some installations ive heard of people doing in homes they have a switch so its not always pumping.
so like they turn it on while dropping a deuce, and when they are ready to shower the water is warm.
It depends on scale, in a big enough building the pipes would be insulted and there'd actually be less heat loss than a
Typical non circulating system
Ah interesting. I've only dobe single-family dwellings
DanoSpanjer
Those would be recirc lines for instantaneous hot water. Where the hot lines end, the white runs back to the water heater
kickarr
Holy shit. That is cool AF!
Nightcaste
Just adding a little clarity here. In some installations, the hot water is kept flowing in a loop. Reduces the "wait to warm up" time.
nobodyrelevant
Another thing are bacteria. Long standing lukewarm water is a good breeding ground for bacterias, legionella die at +60C°
ExplosionFish
And you heat your towels!
I suppose baseboard heaters could make a comeback, since this is basically how those worked to
Ah, I was thrown off by the color and size. I'm used to commercial setups where this kind of manifold system is replaced by mains and
Smoretank
Oh! That makes sense. Is it more common in tankless water heaters?
Guttfunk
It just depends on the distance from the heat source to the tap. Here in Sweden it's needed for all distances above 10m
Churchofthesubgenius
In my US state it’s for commercial and multi housing with shared water heating (what I think the pic is). It’s a rather recent requirement
I don't know if it's a tankless thing or if tankless heaters and recirculation loops just came around at the same time.
I'm not like a water heater pro, just learned a little from researching a tankless heater for replacing the dinosaur in my utility room
pixelsnader
That... sounds like a lot of heat dissipation in the pipes... is it for some specific industrial use?
withfrigginlasers
It's also useful for areas where it's cold AF and they want to avoid freezing pipes.
It’s to reduce water waste when people run the water til it is hot. Required for new commercial and multi unit housing in my county
Wouldn't grey water recycling be much more efficient for that?
This particular photo looks like a commercial or industrial installation. You don't really need this many lines for a single family home

Nah, it's just that people don't like to wait for hot water.

Ah interesting. I've only dobe single-family dwellings

Those would be recirc lines for instantaneous hot water. Where the hot lines end, the white runs back to the water heater

Holy shit. That is cool AF!

Just adding a little clarity here. In some installations, the hot water is kept flowing in a loop. Reduces the "wait to warm up" time.

Another thing are bacteria. Long standing lukewarm water is a good breeding ground for bacterias, legionella die at +60C°

And you heat your towels!

I suppose baseboard heaters could make a comeback, since this is basically how those worked to

Ah, I was thrown off by the color and size. I'm used to commercial setups where this kind of manifold system is replaced by mains and

Oh! That makes sense. Is it more common in tankless water heaters?

It just depends on the distance from the heat source to the tap. Here in Sweden it's needed for all distances above 10m

In my US state it’s for commercial and multi housing with shared water heating (what I think the pic is). It’s a rather recent requirement

I don't know if it's a tankless thing or if tankless heaters and recirculation loops just came around at the same time.

I'm not like a water heater pro, just learned a little from researching a tankless heater for replacing the dinosaur in my utility room

That... sounds like a lot of heat dissipation in the pipes... is it for some specific industrial use?

It's also useful for areas where it's cold AF and they want to avoid freezing pipes.

It’s to reduce water waste when people run the water til it is hot. Required for new commercial and multi unit housing in my county

Wouldn't grey water recycling be much more efficient for that?

This particular photo looks like a commercial or industrial installation. You don't really need this many lines for a single family home

Nah, it's just that people don't like to wait for hot water.
