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
The mat that is placed under a Bunsen burner can be referred to as a heat proof mat.
a heat proof mat ******************** In our chemistry lessons we knew it as gauze [a gauze mat]
It should be placed on a Safety Heat Proof Mat on to a gauze and then on to a tripod.
A gauze mat is used below bunsen burners as it protects the tripod or surface which the bunsen burner might be on. It is most likely to be made of thick metal threads threaded into a mat or square. It is best if it is not touched during an experiment including a bunsen burner as it probably will result in mild to severe burns.
Gauze is used for bandaging wounds, cuts, etc.
A GHD Heat Mat is a very commonly used accessory, especially for those who are travelling. The GHD Heat Mat can protect certain items such as a curler or straightener.

a safety mat or is also known as the bench mat
Heat mat & heat pad - are just different names for the same piece of equipment.
The mat that is placed under a Bunsen burner can be referred to as a heat proof mat.
A heat mat - is essentially a 'flat resistor'. The power supplied by the mains is resisted by the flat element - which causes heat to build up. Heat-mats should ALWAYS be attached to a thermostat - to prevent the reptile getting overheated !
in science, you'll put a gauze mat on top of a tripod( a thing like a stand) above a Bunsen burner. when you sit the thing you want to heat on the gauze mat, it will spread the heat across the thing as it is made out of metal.

A heat proof mat is used in science when doing an experiment with fire or hot liquids. It is to protect the surface that the experiment is being made on
Heat proof mats :) the are used for bunsen burners if you didn't know.
