Our home is heated with baseboard heaters controlled by wall mounted
thermostats. With a thermostat removed {and the circuit presumably
broken} my voltmeter still detects a small AC voltage at the terminals
on the baseboard heater. If these wires touch, they will spark. Why
is there a voltage going to the heater with the thermostat off or
removed? Does this mean the heaters are consuming power even if the
thermostats are off?
