replacement sizes of radiators

ssmh

We are trying to replace some cast iron steam radiators. I have been told to always replace them with a radiator of same output to close to. Does anyone know where I might be able to purchase radiators in the 12" tall range new? Or is there a simpler answer for this situation?

But, really...



You can find more radiator sizes from a private used sale then you can brand new. The variety of new sizes is almost a joke. They are all at least 20" tall. You may have better luck with a wall panel type radiator, like a Runtal.



You can also have a heat loss done on the room to find out what is the smallest size radiator that can possibly be used and still heat the room.

The reason...

for replacing a radiator with the same size, or close to, is a little shaky: the theory is that that way, if the room was comfortably heated before, it still will be.  But... if you have improved the insulation, for instance, you might be able to go with a smaller radiator.  Or if the room was too cold before, you might want a larger one (but be sure to check that the steam pipe and return can take it).



What you really don't want to do, though, is mix types if possible.  That is, if most of your radiators are cast iron, try to stay with that.



May I ask why you are wanting to replace them?  Do they leak?  Or... why?
