I wanna install 8 electrical baseboard heaters. So I need 3 circuits so I won’t over load them. So I wanna know if there’s a way to just install one thermostat

2Why are you using electric baseboard heat to begin with, if I may ask? (Instead of, say, a mini-split or two)– ThreePhaseEelFeb 11 at 18:33

1How much power are those heaters, one thermostat for all, or each gets one– RuskesFeb 11 at 18:58

2Are they all in the same room– Rohit GuptaFeb 11 at 19:49

1Please clarify your specific problem or provide additional details to highlight exactly what you need. As it's currently written, it's hard to tell exactly what you're asking.– Community BotFeb 11 at 19:49

Sure. Other than this being pure madness unless you have free electricity, it's a common enough install from when electricity was "going to be too cheap to meter" and lots of baseboard was put in. These days, a cold-climate (or your-climate if not cold,) or ground-source heat pump makes far more economic sense.
Anyway, you have a single thermostat that controls relays or "contactors" for each circuit. Typically that's a 24VAC thermostat circuit, and the relays have 24VAC control coils, and contacts rated for 240VAC @ 20A resistive. Commonly they are mounted adjacent to the breaker panel supplying the power, so that when they are off, only a few inches of cable from the breaker to the relay are energized.
