I have an old-style, convector-type, wall mounted room heater that
has a small leak. It is similar to baseboard heat, but the heat is
provided by the hot water that goes through the convector element.

Here are some photos:

The convector element has a very tiny leak near one end that I can't
quite locate with the convector connected up and working; and, even
with it disconnected I can't quite locate the pinhole or whatever
that is causing the tiny leak.

If you can remove the item, a radiator repair shop may be able to
help. Just smearing flux on the old metal will not help the solder to
stick, you need to clean the metal first and that is exactly what a
radiator shop would before they try to repair it.

Just an interim update. . . . ,

I first went to a local welding and metal fabrication shop. They are always
very nice and helpful there. They looked at it and weren't sure if they
could do what I needed. But, they also suggested going to a radiator repair
place and said that what radiator repair places do all day long.

I found and went to a radiator repair shop. The guy said that they can fix
it. They will use a "glass bead machine" to clean the entire area, then use
special liquid (not paste) flux, then do the solder/fix, and then pressure
test it to make sure it is fixed. He said that they will do both ends even
though just one end has the leak right now. And, the price will be "no more
than $89" to do both ends.

It should be ready in a couple of days and I'll post back how it all turns
out.
