HVAC Q&A: How Do I Heat the

Cadet heaters are only approved for use with up to 10 gauge wire and a maximum of a 30 amp double pole breaker.

You can wire up to 2 of the 1, 600 watt 240 volt register heaters on either a 20 amp double pole breaker using 12/2 wire with ground, or on a 30 amp double pole breaker using 10/2 wire with ground.

When wiring more than one heater to a single

Hi Alex and thank you for your question.

When wiring more than one heater to a single thermostat you will want to make sure the combined amperage of the heaters does not exceed the amp rating of the thermostat. Each 1, 600 watt 240 heater will draw 6.7 amps. We would recommend using an electronic thermostat for the most precise and accurate temperature control. The TH114 double pole thermostat would be a great option for your application. It's rated at 16 amps which means you will need 2 thermostats to run 4 of the1, 600 watt 240 volt Register heaters. Please see the link below.
