I am setting up for an African House Snake - to be acquired at some point in the new year.
We have a 12"x12"x12" exo-terra tank left over from use with garden snails

which should do for while it is small.
I am planning on purchasing the 24"x18"x18" tank (Exo-terra again) when needed.
From what I read, most AHS never grow bigger than 2 or 3 feet... so that size would be sufficient, no?
I was looking at the
9.8" x 5.9" (10 Watts) IntelliTemp heat mat as an in-tank heater.
I would be using river rocks and potted plants as substrate(that's the plan at this point anyway).
It would be hooked up to the
Herp Power Proportional Thermostat or something equivalent (haven't got anything but the tank yet)
That said, I have 3 questions about it:
1. Would it be enough to create 32 Celcius temps on the hot end? The room fluctuates between maybe 13 and 26 degrees? depending on the season and other factors...
the 13 could be adjusted closer to 20 by a room heater (I have one running during the day for my plants) but I would prefer to avoid running it 24hrs a day if possible...
2. Would it be safe? Fire-hazard? Burn-the-snake hazard?
3. Is it an appropriate size for a 1'x1'x1' tank... i.e. would it allow for a suitable temp-gradient in such a small tank. And would it still work for the 2'x1'6"x1'6" tank?
