The basement heaters are on a 220V 20A circuit. As per the nameplate ratings, they total 15A when all are on together. They are zoned to 3 different t-stats and AFIK are either on and drawing their max ratings or off, there is no in between. My FIL wants to add another heater with a rating of 5A to bring the total to 20 possible A. Question is, do I need to add a new circuit and rebalance them ? The heaters are a resistive and therefore predictable load, not variable like motors are.
