Easy yet safe way to heat water?

[GRABibus]

During the day, my water bowl is heated by the 50W spot lamp of the enclosure..
At night, the room where the enclosure is is from 68F to 73,4F and I don't heat the water. The water becomes at ambient temperature.

If the water is in a separate container sitting on the glass you can use an under tank heater, that's what I use.

I have a Ranco thermostat I use for my leopard gecko's heat mat. It came with a power strip but only one probe. If I go the UTH path would I need another thermostat? Isn't that supposedly why it's wired (it was pre-wired, I know nothing of electronics) with a power strip?

To Hoppity: I have a stealth heater (Stealth Pro), which is adjustable up to 88 degrees. Problem is it gets really hot on the end of it, likely where the actual heating unit/thing is. I touched it once and it scaled me, which made me worry about putting in my pixie's water box. Here's what I'm currently trying to do to solve the problem: I cut a piece of square, plastic pipe (similar to PVC, but it came from a plastic fence post) with an electric saw, and plan to use that as a sort of improvised "sheath" for the heater, and glued it into a corner of a pan just like the one in the cage with the weaker heating device with silicone sealant. I carefully cut to a size so that I can sheath the hottest part of the heat but can still take it out so I can change the water. Waiting for the sealant to cure at the moment. Hoping this will work. Best idea I could think of, though the heat mat idea did cross my mind before.

We must not sell this type of heater here, but yes 88 degrees is way too warm! I see what you are doing but it sounds like alot. I have a submersible heater, no need for foam or silicone. I have a thermometer in the water and check my heater every day, it only gets to 76 degrees. But its safe that way, being pre-set. Is the heat mat for use above only or under the water? And I have not seen pixies here so I don't know their environment. I have 4 FB's and all get along great. Glad you wrote!
