Looking to update steam radiator in old San Franciscan building

Hi. I have an outdated steam radiator, 1 pipe system. I want to know what the best option will be if I want to update the heating system. Will it be more cost efficient to just keep the old system or to put in a hot water radiator. Do I have other options?

    Don't really understand the question. If you wan't to replace a radiator yes that can be done

    If your thinking about changing the radiator yes that can be done. It's likely not going to improve the efficiency at all. If your reasons are esthetic or for space/location the answer is also yes it can be done. How to go about it is another matter. More details would be in order.

    Sorry all, I mean to say to replace the steam radiator with hot water radiator. Which one will be more efficient? Do I hae other options for a more efficient heating system. Thank you

    A change to a hot water radiator would require changing the whole system to hot water, including the boiler.
    What makes you think your system is inefficient? If properly installed, and maintained, steam can be as efficient as hot water, and sometimes more than forced hot-air.--NBC

    The tenants in the building wants to be able to control the heating. With the current system, they are unble to do that. In addition, the current steam radiator is very old and makes loud noises. What options do we have if we want to update the heating system?

    So the sounds are the result of something wrong, probably something not being installed properly when the boiler was replaced, but there are lots of other possibilities, pretty much all of which can be fixed.

    Is this one pipe or 2 pipe? @ pipe is very easy to add control to, it can also be done on one pipe but is less tolerant of bad design.

    It is unlikely that the slight fuel savings of another type of system would make up for the cost of replacement of all of the piping and emitters. Fixing the problems with your current system could result in significant savings.

    Are the apartments over or under-heated?
