installing a radiator

Correction: MP and I agree on improper operation of cast iron baseboard radiators with single pipe steam *as the length of the radiator increases.
I like 2 to 4 feet. And will go for 5 to 6 feet in a pinch. No more than that though. As the above referenced heatinghelp.com poster informed, he can hear some water sloshing internally at 10 feet

Anyone know the ballpark cost to have a new steam radiator installed? basically the existing one is big and positioned so as to take up space that could otherwise be occupied by a desk or bookshelf so i want to have a new one installed under the window adjacent to it. i do not think this would involve any plumbing changes other than having the pipe valve coming out of the floor elbow to the right rather than the left…….any insight is much appreciated.

If you put a modern cast in, height will be off. I still have wood blocks under one in my house.

the new one would have to be shorter so that it fits under the window sill. i don’t care if there are blocks under it, the current one has blocks under it.

Remember that changing your steam radiators has a side effect on the rest of your Heating System….actions on a system are never isolated.

this is a concern of mine because i am in a multi family building with a shared heating system. if the new unit is sized correctly (in this case it needs to be physically shorter but could be wider or deeper) to match the old unit I would think there would be no issues? I also was hoping to get this work done before the heating season starts so as to not interrupt any of the neighbors.

@jeremykiltspropmgr Are you sure A Real Good Plumber did that radiator installation? I know the owner fairly well and I think he would know not to use a piece of cast iron baseboard heater for 1-pipe steam. And hanging it on the wall like that? Never. There are wall hung radiators made specifically for that. What’s in your picture is not a good installation by any professional standard.

this was my impression as well, and certainly not worth $2000.

I have to agree w/ MP…that is a god awful installation. That is a section of cast iron baseboard designed to rest on the floor…I’ve also known the owner of the plumbing outfit for 30 plus years and its hard to believe that is his company’s work…

@master plvmber what comparable wall mounted unit would you prefer in this location?
Does this one look the best? No. Does it it save a ton of floor space? Yes. Can it be made to look better with a slim line wooden cover if needed? Yes. A Real Good Plumber is the only plumber I have been able to trust so far to install wall mounted radiators. This one helped me rent an alcove studio in Chelsea at a one bed price. Did the plumber prefer a floor unit? Probably. Instead they installed what I asked to achieve my client’s desire of highest rent at lowest unit prep expense

thats not a wall mounted radiator….thats a baseboard radiator mounted on a wall
runtal makes a line of wall mounted steam radiators

@jeremykiltspropmgr The manual for this type of radiator specifically states it’s not compatible with 1-pipe steam as the small ¾” pipe connection does not allow for sufficient counterflow of steam and returning condensate uniquely created by 1-steam systems. Did it really save that much floor space? Whatever. That’s subjective. But this is not the first time it’s been tried and there are multiple products specifically for this application.
https://ocsind.com/wp-content/uploads/2016/03/15981-OCS-Catalog.Updated15-5.pdf

Look, if it works for you, then there’s nothing to discuss. It’s just surprising. I would expect some amount of condensate to leak out of that air vent though, and certainly some noise.

@eman137 I find that usable floor space is much more important to property managers who are trying to maximize rents than it is to plumbers. The Runtal radiators look great but you can see from my picture that they do not accomplish the low profile goal that mounting a baseboard radiator directly to wall does. Every inch matters in an 80 square foot room without a closet when trying to maximize rents. Could I have had a carpenter cut out the wood baseboard and install directly on floor? Sure. Client didn’t want to pay for that. Instead, I got a plumber to do a technically sound installation in less than 24 hours. I understand it is not the intended use but it works very well here.
I’m curious if the stainless steel Runtals retain heat as long as cast iron models. I would not want to mix and match those in a multi family building if they go cold faster than the other rooms/units sporting cast iron

Yes. I’m well aware of the role of a property management company. We spend hours every year being told what’s best by people making price-driven, rather than mechanically sound, decisions.

@master plvmer my client would strongly disagree with your claim that the savings in floor space is subjective.
This thing is quiet and has no leaks. Look at the significant pitch used to achieve that. 6 feet and under has worked well for this application many times over. Don’t do this application in a length over 7 feet.
Your slenderized recommendation would not have been as low profile as needed here but I’ll definitely keep in mind for a large and high end renovation I’m managing in SoHo. Thanks for the recommendation!

@master plvmber I don’t tell contractors what’s best. I tell them what’s best for me. My favorite vendors are the ones who tell me how it is supposed to be done, but then work with me to customize their expertise to apply to my need. The picture I posted above is a perfect example of that

@randolph I find that wooden checkers make better looking shims than wood blocks when needing to lift a modern radiator. Wood glue between them (and to the floor if you are set on the look) when stacking adds stability
