Just wondering if anyone else uses these panel heaters from Exo-Terra (just scroll down a little to see them):

They're the only Exo-Terra under tank heaters available here in Japan, and don't adhere to the bottom of the enclosure like the ones I've seen available overseas. They just lie on the floor underneath the viv, leaving a gap of about 10mm between the heat panel and the floor of the viv.
I've been running mine for the past couple of days without any substrate, and the glass floor surface directly above the heater is getting up to 38C/100F. The instructions (and dealer) say a thermostat isn't necessary as the panel has a safety fuse, but common sense is telling me this is too hot! I'm going to put some newspaper down and test it again to see if the temperature will come down a few degrees, otherwise I'll use the thermostat I have on my heat bulb and just run the bulb without a thermostat for now (left running 24 hours the warm side air temps don't get above 33-34C/91-93F, cool side at 28C/82F).
