Heat mats can heat a substrate up to 100F (so have to be thermostat controlled and some brands may vary in heat output) but a deep substrate will insulate the heat but the surface temperature is not important for a burrowing frog, which spends its time in the substrate. Also, analogue thermometers that stick on the side of the tank do not measure the heat properly as the heat is not radiant but conductive, so the thermometer needs to be directly on the mat for a proper reading.
