Qmark Double-Pole Wall Mount Thermostat - M602W

How many Thermostat(s) do you need for your Electric Heaters? This thermostat, Model M602W, is rated for 21 amps at 220 volts. 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 220 volts.   

2 times 1,500 watts = 3,000 watts   

3,000 watts / 220 volts = 13.64 amps   

So, Qmark M602W Thermostat would be big enough for this application.
