How do I connect 3 240 v blower heaters (each heater with wall thermostat is in its own room) in a single circuit?

I would run the feed to the first thermo and then daisy chain on to the other two.
The run a switch leg to each heater from the thermostat.

What size are these heaters? Will the all fit on one 20A circuit? If so use 12/2 for everything.

#10 will overload boxes real fast if you have to bump it up to a 30A circuit, which is legal for this circuit.

How do I connect single pole thermostats to operate blower type heaters. The wire from panel is 12-2 and is daisy-chained as you suggested. There are 3 heaters in the circuit.

Daisy-chained the line from panel and put in individual lines to each heater as you suggested.

How do I wire the thermostats and carry power on to the next... Using 12-2 wire.
