Radiant Floor Heating/1955 copper radiant slab work

Question
I have a home built in 1955 with a copper radiant heat system.  I wanted to remodel the bathrooms and replace the tile currently on the floors.  I'm concerned that the tile removal could damage the radiant heating system.  

Do you have recommendations on precautions I should take in the kind of contractor I use or with the tile removal methods the contractor should use?

Answer
1955 was a good year for copper radiant floors. Many are still going strong, but many more have starting leaking. We consult on many of these systems. The vast majority have copper or steel pipe place at or below the concrete. Many suffer from corrosion inside or out.

Most tile was set in a thin layer of mortar on top of the slab so chiseling the tile off using typical methods should not be problem. If you can feel the heat output of individual tubing runs caution would be in order.
