I would not remove the heater code. I would just relax it so it doesn't do anything.
Setting TEMP_SENSOR_BED to 0 disables the heated bed. I believe Marlin will complain if you set all TEMP_SENSOR_n settings to 0. It wants at least 1. Roxy, I wonder if it's worth modifying Marlin to allow zero temperature sensors, since I see more users all the time who would like to do paste extrusion or ceramics.
