Whoops.
It is better to have a heat source along one side of the enclosures so that there is a bit of a temperature gradient like with reptiles. They can move closer or further away from the heat source as they need to.
If you can, an even better way to keep your enclosures all within the warmer ranges is to heat the whole room evenly. Attach an electronic thermostat to a panel heater or something similar. This will keep the temps of the whole room between specified set amounts. If the room gets too hot, the thermostat switches off the heater, when the temp drops below a programmed amount the thermostat switches the heater on and so forth. This method is a bit expensive and only really economic if you have a good number of T's.
Some people put heat pads under their enclosures which I feel is a very bad thing. T's burrow to cool down if they get too hot (I should mention this isn't the only reason for burrowing) and if the heat pad is at the bottom of the enclosure, they are burrowing closer and closer to the source of the heat, often cooking them alive.
Otherwise, as TH says, N. chromatus is a burrowing species. Perhaps your's is just acting perfectly normal
