Can I use a single pole thermostat on a double pole hookup?

Contractor's Assistant: Just to clarify, do you think this is a larger HVAC problem, or something specific to the thermostat?

Thermostat i guess.

Contractor's Assistant: Do you plan on doing the work yourself?

My husband

Contractor's Assistant: Anything else we should know to help you best?

We have 2 baseboard heaters totaling 16.7 amps. they are both wired to the same box in wall. we want to use a digital thermostat but the only one i can find can handle the amps but it says single pole.

You should be able to use a single pole thermostat. All a thermostat is , is a switch but temperature controlled.

In most cases you would just use the single pole thermostat to break one hot leg and connect the other hot from power directly to heater.
