Can I branch a heater circuit before the thermostat and feed another heater/thermostat if I stay within load limits of my wire and breaker? Without turning this into a math lesson I will be staying below 3500 watts total on 12awg nmb with a 20 amp breaker. Am I off track or is this an option? I'm about out of room in my box but some existing circuits have only a single 1500 watt heater on them.
