I have a house built in the mid to late 1960s which has electric radiant heat in the ceilings. They used a single strand solid copper wire and ran it back and forth (about 4 inches between runs) between two sheets of drywall. I am having a real problem locating any replacement wire. The original is labled as "90 (degree) C style 1216 Radiant Heating Wire"
Does anyone know where I can get some replacement wire?
