I am STILL hearing conflicting info on this though. Some people say it’s fine to close it, just not fine to close it part of the way.

Last year I was getting nosebleeds from the 17% humidity we had with the heat on and windows open. My super was just like “shut the radiator off, no big deal” so that’s what we did. No water hammer.

Open or closed is fine. Low pressure steam systems don’t care. Just not halfway.

If you want to read the best source of information on the web about steam heat, check out the Strictly Steam subforum of heatinghelp.

It is an incredible resource, the information there has helped me unfuck years of hack jobs on the steam radiators at my home and office.

I've always been told that the actual answer to this is "It depends and you should ask your super" because there are apparently a few different ways in which a steam heating system can be set up and in some cases the knob/valve is there in case the radiator needs to be removed or replaced and when you turn the knob to off, it cuts off steam to anything else along the line.

If the service valve is in good condition it might not be a problem, but using an air release plug / smaller orifice is a more reliable permanent solution if you have issues with water noise.

You shouldn’t close it because edits a building-wide system designed to work as a unit. If radiators are closed, the system is not working as designed. Open your windows.

This is true to an extent, steam can be an absolute bitch to balance.

A lot of the one pipe steam in NYC was designed for coal boilers which came to temperature & pressure very slowly compared to the efficient gas boilers currently installed.

You are way out of spec from “design” already. I don’t know what the theory of why it matters is, but in practice it does not matter much or all of the time.

Hell, con Ed will give you TRVs which close off a radiator about as effectively as if the valve is closed, the boiler can’t tell the difference

I also have issues with nose bleeds and in my case air purifiers help too. Furniture and beds can locally harbor dust mites even in dry apartments and cause irritation.

This also led me to discover ultrasonic humidifiers produce a smoke-like level of fine mineral dust.

Humidifying a leaky apartment can be very difficult. For my unit it requires multiple gallons per day. I think it's easier to seal the area and reduce the heat to what is actually needed.

ZweitenMal t1_irno20i wrote

My apartment gets so stuffy with the windows closed. If you open them from the top you get a little flow of fresh air and it vents the excess heat naturally.

I don’t mind refilling my humidifier every day. I also put baking pans full of water on top of the radiators. Helps as well.

Bertie_Woo t1_irnpwti wrote

Oh, I'm curious about the baking pans, is that enough humidity for you?

I am sensitive to noise and live in a windy area, so opening the window doesn't work well for me.

Last year I disabled one radiator, used wet towels on the other radiator cover, and sealed all my windows. It worked well but damaged the radiator cover paint. I tried pans initially, but it didn't evaporate enough. I ended up DIYing a solution with Ikea buckets, evaporative wicks and a large quiet computer fans. I'm on the top floor of an old walkup with skylights though, so it's probably a worst case.

Bertie_Woo t1_irnqmxf wrote

In theory I feel like there should be a device that taps the single-pipe for humid air. I suppose that wouldn't fix stuffiness though.

Forced air HRV (Heat Recovery Ventilation) systems could possibly help, but I haven't seen a window mounted version. It would probably be noisy anyways.

ZweitenMal t1_iro17as wrote

The baking pans do seem to help. Adding a proper humidifier helps much more. I bought one with an automatic setting--you set the humidity level you want to maintain and it runs and shuts off as needed. And yeah, it's running nearly all the time just to keep it to 40% in winter. It's a Vornado, I forget which model.

In winter I also have to pay attention to using more moisturizer and lotion (all over my arms and legs) and a good lip balm, as well as drinking my usual level of water. I'm not as thirsty because I'm not hot, so I have to remind myself.

Winter is a dry time of year, that's all there is to it.

Cj_Joker t1_irmwoef wrote

If you're talking the big cast iron radiant heaters, you're supposed to use a cotton or wool cover with this, which restricts the airflow through the heater, and lessens the actual radiant heat. You're not supposed to use open windows to balance things out (although that does help keep fresh air in the place and lowers the chance of illness).

Covering the units helps preserve the heat capacity in the system and allows people further down the line to receive more heat, as opposed to having to absolutely crank up the heat in order to get at least a small amount of it to the end of the line, when they're all just exposed and blazing away.

They used to sell covers specifically for this back in the day... not sure why this just fell to the wayside.

And do not use synthetic materials on it.

With all of my windows open and the radiators going, it's still minimum of 85 degrees in my apt if I don't run my A/C. I can't turn either of my radiators off (I have two and a heating pole).

There really should be a maximum indoor temperature rule too.

mule_roany_mare t1_irmkapx wrote

If you don’t want to close the valve on your steam radiator see if the owner will install a TRV, Con Ed gives them out free/cheap & it’s a 5 minute install.

They go where the air valve is now & work the same way, except they have a wax seal that closes when the room is too warm. After a cycle or two when the radiator can’t vent the air it will keep most of the steam from entering.

If some villain noticed it was too hot & put a piece of electrical tape over the vent it would keep 90% of the steam from entering.

Bertie_Woo t1_irnigjb wrote

You can ask your super to install an air release plug or smaller orifice. Opening the window is not ideal since all the humidity will escape and dry you out.

mule_roany_mare t1_irlbns9 wrote

This is dumb advice which makes tons of assumptions.

Are they talking about one pipe steam or two or anything else?

For one pipe steam the valve needs to be fully open so that the condensation can drip back down the riser, it's also why your radiator needs to be raked towards the riser too.

You have to keep the valve fully open or fully closed, it's not a temperature control. You can install a special vent called a TRV which gives you some control though. A steam radiator needs to let air out so steam can come in, the TRV has an expanding seal so that when the room is warm enough it will trap air.

If you want to turn off your radiator & don't have access to the valve (or you just got it to stop leaking & don't want to mess with it) you can just cover the valve with tape. After a cycle or two your radiator will only have room for trivial amounts of steam.

TLDR

the valve between the pipe & the radiator needs to be full open or full closed. The gospel of dry steam. Opening windows to control temperature is a dick move

Is this also true for two pipe radiators?

mule_roany_mare t1_irlmilu wrote

Probably, I don't see why it wouldn't work. If you have a vent for air plugging it will trap air. If air is trapped a minimal amount of steam will get in.

I also don't see any risk for damage, but I've never even seen 2 pipe steam in person.

I know about one pipe steam because I've had to fix 20 problems with my 120+ year old building.

__-__-_-_ t1_irmw16q wrote

If you have a two pipe system you're better off just shutting the valves. Two pipe valves are designed to be used repeatedly and to be partially closed to throttle the heat. If you see multiple valves, only touch the one that's closest to your radiator on the steam supply side, though. That one is the one for you to use, the others are just to isolate the radiator for repairs and will probably start leaking if you wear out the seals by repeated use.

You're bolding this like a lot of renters (myself included) have choice in this. With the windows open and the heat on my apt is a minimum of 85 degrees. It would be well over 100 if I didn't open the windows.

It's the landlords, management companies, and supers that need to do something about it.

1

mule_roany_mare t1_irs4721 wrote

Unfortunately the landlord is bound by the lowest common denominator, that means keeping the coldest apartment at 68 degrees (plus a margin of error in practice).

Owners would love to save money, but the dick who refuses to close his window is also the dick who calls the city & gets you fined. It's a problem in coops & condos just as much as renter buildings.

It's a catch 22 that hinges on uncooperative residents who have zero incentive to conserve energy.

People are, largely, opening their windows so they don't die of heat stroke.

If tenants don't control the heat, it's not tenants' faults if the only way to literally not have a 110 degree apartment is to open the windows.

I have radiator heat. The landlord and super control the boiler in the basement and when we receive heat. My two radiators cannot be turned off with knobs and they are behind radiator covers that are fused to the wall and painted shut and I have a heating pole that you also cannot control.

I don't control my heat. When it's on it's on. When it's off, it's off. I live in a pre-war building uptown - I'm not sure why you think I have any control over my heat.

Do you have one pipe steam?

What is a heating pole? Are you talking about the riser that runs between floors?

im_not_bovvered t1_irsnfjb wrote

If you know how heating works, why are you asking me what a heating pole is? I feel like you know exactly what I'm talking about but are trying to be a know it all. Heating pole/radiator pipe/steam riser. Take your pick. It runs from the bottom of the building to the top and mine has a vent on the top because I'm on the top floor.

I don't think you actually know how it works if you think I have options. Once again, *I do not control my own heat.* I cannot turn my radiators on, I cannot turn them off, and I do not have any control over the boiler. If I could find a wool cover that I could be assured wouldn't catch fire, I'd try that. Other than that, I cannot do anything about the amount of heat I get.

Also I am a tenant in a rental building that is 76 apartments big. Our boiler room is locked - how am I supposed to know what kind of boiler we have? I could go on a dive on DOB that may or may not tell me what type of boiler it is, but the fact remains that the landlord and super control when it is and isn't on.

How can you be so sure of what you don’t know & also confident you know everything?

im_not_bovvered t1_irsrlaf wrote

I literally told you exactly what my setup is in an earlier comment.

I have one of these:

https://renov8or.blogspot.com/2015/10/covering-exposed-heating-pipes-with-rope.html

And two radiators that cannot be turned off (the knobs don't work) that are covered with metal covers that are fused to the wall and cannot be removed.

I do not control when the heat is on or off in my building, so why does it matter what kind of boiler I have? I don't control it. Unless my super replaces my radiators (not going to happen) or sets them up with a temperature control (again, not going to happen - I have asked) or I can control the boiler (I don't), there's nothing I, a tenant, can do. If it's cold, call 311. If it's too hot, tough - there is no maximum heat law in New York City. Literally the only things I can do is open my windows, which is how these buildings were designed for combating illness, and run my a/c.

If you are familiar with radiator/steam heat in NYC you know exactly what a heating pole is and you're just being pedantic. I am confident about the building set up that I LIVE IN and how the heat works in my apartment building. Stop trying to gaslight me. This is not my first pre-war apartment with steam heat.

mule_roany_mare t1_irssi01 wrote

No one is gaslighting you.

You just don’t know as much as you think you do. You don’t need to control the boiler or the valve to prevent heat from entering your radiator.

Your options are different depending on what type of heat you have which can be determined by your radiator.

All the stuff you keep saying isn’t what’s relevant.

Enjoy your heat

There's a class of systems that were built during the 1918 flu epidemic that are steam and crazy to live with. There's no water hammer capable in them, as they steam and boil out at their top nozzle.

If you don't leave your windows open in the winter the systems don't work correctly, and if you do keep your windows closed or turn off the radiator valves you will die from heat stroke or an explosion of some sort? Whatevs. It's a ridiculous mystery and we all just live in millions of apartments that have free heating while needing to leave our windows open all winter with exhaust fans in the window sashes to blow out the insanely hot steamed air.

It's calamity! It's so ridiculous it barely makes sense explaining it to anyone that doesn't live in a building of this specific age in this specific location.

Otherwise heating systems, in most American homes, have similarities to European systems, but NYC around 1920 was ridiculous and a bunch of us are still living in that.

Steam hammer is absolutely a problem

I’ve been trying to fix it on one of the lines in my building for a few years.

One drop of water makes a liter bottle of steam. That a lot of displacement. If your condensed water return line isn’t pitched properly anywhere it can be blasted back and forth with tremendous force.

Someone replaced their big cast iron radiators with pressed sheet metal ones & the hammer knocked it right off it’s wall mount.

The problem with steam IME is they were designed around slow rise & long cycle coal boilers & the valves for air to escape are way too small.

Unfortunately a lot of the companies in the industry just follow conventional wisdom passed down the generations. When my building had to replace it’s boiler I asked the organization that drafted NYC code for recommendations.

Bigger valves at the top of risers, TRVs on the radiators & pressure just low enough to reach the furthest radiator from the boiler & everyone will be perfectly pleasant. Insulating risers can also help a lot if a unit is still hot.

Getting all the residents to allow that to happen is the real hang up.

If you have a one-pipe steam system (the most common in smaller residential buildings in the city), there is another way to effectively stop a radiator from heating that doesn't involve opening and closing the valves. You just have to block the air from escaping out of the air vent with duct tape. This can often be just as effective as closing the steam supply valve, but you don't run the risk of creating leaks around the valve stem by using it repeatedly (the valves ARE meant to be used, but only for maintenance purposes, not opened and closed over and over again).

Beware that doing this may cause reduced heat output and / or increased hissing from other nearby radiators because the air in the steam lines has one fewer place it can escape. As long as every other radiator has a working air vent this shouldn't significantly harm the overall effectiveness of the system, though.

If you don't know what part of the radiator the air vent is, this article has some nice illustrations: https://www.sparksuper.com/5-steps-to-healthy-steam-radiators/

Also consider just telling your super / landlord the heat is on too high. Talk to your neighbors and see if they're hot as well. Sometimes they just set the central system really high assuming somebody is always going to be cold and everybody else can just open a window. If everybody is hot, though, that excess heating is just wasting their money.

Sea_Sand_3622 t1_irm6uis wrote

The one pipe system is very inefficient but if you want to be warm throughout the winter season until the end of April, then leave the valve fully open. You can always open the window, use the ac or a fan. The landlord controls the boiler , you control the window.

The valve has to be either fully open, keep turning it counterclockwise until it stops turning. Or fully closed, keep turning clockwise until it stops turning .

If it’s fully closed and you hear banging noise , then your neighbor above or below your apartment, has their valve partially open.

The landlord would like to do away with the inefficient boiler,,especially with the price of fuel having gone way up. He wants to replace the boiler with a more efficient individual electric unit inside every apartment that you would control, like in a hotel/motel, but you would pay the electric to use it , he can’t do that because of the rent control laws that govern the rent control tenants in your building.
