Help!! Somewhat unique issue with heating in cage.

[Diangelo]

So I have this beautiful young butter enchi ball python and we love her to death which is why I'm freaking out in short the heating mat we originally had worked with our electricity here in Israel which is 220v the issue is it gets so hot that it heats up the glass to like 50 degrees celcius or 122 degrees farenheit which is way too hot and frightens me that if she pushes aside the substrate shell get hurt and due to the lack of snake owners in Israel I had to order online a thermostat and heat pad but they were American made so I bought an adapter that lowers the voltage to 110/120v here's my issue when I set up the thermostat I used aquarium silicon to glue the probe against the bottom of the tank to prevent it overheating the glass and set it to 38 degrees celcius which is 100.4 f and yet the hot hide temperature doesn't rise above 29.1 C or 84.4 F and the cold side and hide won't rise above 26.4 C or 79.5 F there is about a fourth of an inch of substrate at the bottom of the tank it's a mix of exoterra jungle floor substrate and sphagnum moss to keep up humidity which hovers at around 50% I'm really worried I don't want her to be too cold and get sick or worse should I be freaking out am I right to be afraid of these temperatures? Should I put the old heat mat back?

Are you measuring the temperature at the glass? Don't read the temps on top of the substrate. 100f is too hot. It should be 90F. Also the probe needs to be between the glass and heat pad outside the tank.

So should I turn it down to 90F even if the substrate reads at a much lower temp and the cold side doesnt rise above 80 F?and in regards to the probe why should it be outside the tank and not against the glass I've just heard a lot of different opinions from different places which is why I'm also asking here

Yes the glass temperature is the one you dont want hotter than 90ish. Your snake will push substrate out of the way as it curls in its hide.

All right thanks you've really helped a lot

Sounds to me like you are going to have to use some form of overhead heating, either CHE or RHP. Heat tape is designed to heat the surface, and will only raise air temp above it minimally. I have never been able to use it as sole source of heat for a BP. My home is at about 70-72 F and heat tape or a heat pad on a glass enclosure at a safe surface temperature will not get the air temp on the warm side above 77 or so, and cool side stays room temp. It is a little better in PVC but not much.

Ok cool and that should raise the over all heat cuz this morning when we checked the cold side it was at 24.4 C or 75.5 F
