I've presented this before and was guided to check out the baseboard

I'm hoping there is something like motor-magic that can be fed into
the hot water heating system which would find its way to the leak.

Anyone have any good ideas??? * Thanks

So...how do you know there is a leak if you don't see it in the room
below?
