I've got an idea:
I will buy a decent amount of those water holding crystals. Get some water, boil it, then put it in the fridge. Put the sterilized water in to the crystals and wait until they expand. Then put the crystals in a large hot water bottle. I can re-use it that way and can replace the crystals once a month. Put it in some thick pillowcase and leave in the enclosure in the morning when I go to work and return it to the freezer when I come home.
Of course, this only works for the "out at work/shopping for the day blah blah blah".
It does NOT work if you are NOT at home for a few days. So...here we go.
I believe my air conditioner has an "AUTO RESTART" feature. Why is this important you say? Pretty simple, when the power gets knocked out during one of those notorious afternoon/evening thunderstorms, your airconditioner will REMEMBER to turn itself back on. Why would that be important? I think a 10 year old child could understand the concept, so I am only going to explain this once.
Let's say you are visiting relatives for 3-4 days and you won't be home - you leave your airconditioner on for the duration of your absence, cooling mode, 32 degrees. You are away from home for 4 days. Left home on Friday morning, returned Monday midday. Saturday night there is a nasty thunderstorm. The power gets knocked out, and the air conditioner turns off at the mains like everything else in your house. The power comes back on in 5-10 minutes. If your airconditioner does not have an AUTO RESTART feature, guess what it does? IT STAYS OFF. Sunday is a really hot day. Like 40 degrees hot. Your airconditioner is NOT ON, so what is going to happen to animals (ANY ANIMAL NOT JUST A REPTILE, HUMANS INCLUDED) inside a house that can get 5-10 degrees hotter than outside temperatures? Can your snakes withstand 45 to 50 degrees? Could YOU withstand 45-50 degree heat for 4-6 hours? How much money do you want to bet that YOU (as well as your ANIMALS) would not kark it in such brutal temperatures? What about Monday? What if it's another stinker like Sunday. You're up ***** creek.
If your airconditioner has an AUTO RESTART feature and it is ACTIVATED like it SHOULD be, then your airconditioner will come back on, and continue to offer cooling to 32 degrees, so when Sunday and Monday get brutally hot, your snakes have at least a chance of being protected from 45-50 degree heat.
32 degrees on cooling mode is not comfortable in human terms, but it WILL stop your animals from getting COOKED. At 32 degrees, it has a lot of leeway in terms of when it will be operating, so that it will not be terribly expensive to run. It will only operate on a hot day and considering it's only set to 32 degrees will not require nearly as much energy as it if was set to 26 degrees.
Later on in the year I will contact an airconditioning service and have them activate this feature (if it isn't already so). How they do it, I don't know, but the airconditioner manufacturer states this can be done. In fact I'd be disgustingly surprised if they DIDN'T activate this. In fact, really quite pissed off, to put it mildly (like I want to swear my brains out at them kind of pissed off) and I do remember who installed my A/C system too.
