### How many watts does it take to run a heat mat?

I don't know what exactly you mean by a "heat mat", but your
question is kind of backwards. You don't run an electrical device
*with* watts. You run them to *produce* watts (watts of light,
watts of heat, watts of sound, etc).
I believe the thing you are really asking is how many amps are
required to run your device.
As an example, consider a "1500 Watt heater" that is made to be
plugged into a typical wall outlet in your home. The voltage in the
wall is 120V, and the heater will produce 1500 watts of heat when
plugged into that 120V. To calculate the amps, you divide the watts
by the voltage.
1500W / 120V = 12.5A

### How many watts can run through 12-2 wire?

Wire is rated in ampacity, You can use only 80% of the rated
ampacity. Voltage and amperage are inversely proportional. So at
120 volts alternating current you safely run 1800 watts ( I have
added a small safety margin). At 240 volts you can run 3600
watts.
I hope this has answered you question
Ampsxvolts=watts watts/volts=amps
