There is a slightly warm wire coming from the home fuse box. We replaced all of the parts in the old hot water heater, including the wire to the fuse box. A new wire was run from the box with a new circuit breaker. Everything to code and the new wire is still a bit warm all of the way to the water heater about 15 feet away. Am thinking about buying a new hot water heater, but am concerned about what would make even the replacement wire a bit warm.
Thanks for your help
