How to figure out how many Thermostat(s) you need for your Electric Heaters?
This Thermostat - Qmark M601W is rated for 21 amps at 110 volts.
So - to figure out what you need - add up all the watts your heaters will use
and divide by your volts. Watts divided by voltage = amps.
When in doubt - use a lower voltage.
For Example:
2 Electric Heaters at 1,500 watts each at 110 volts.
2 times 1,500 watts = 3,000 watts
3,000 watts / 110 volts = 27.27 amps
So - model M601W would not be big enough for this application and
you would have to
use two separate thermostats - one for each heater.
