Home made Incubator

[Homebody]

So Im attempting to make a homemade Incubator for my ball python eggs. I currently have a gutted under the counter ice machine, a fish tank heater with thermostat, some heat pads made from flex heat tape, fans, a Vivarium Electronics VE-200 controller.

Now my ice machine has a plastic inside that resembles a plastic tub with a drain and valve on the bottom, I plan to use R.O water inside the ice machine as the primary heat source and the flex tape heat pads tapped to the sides with a fan circulating the air. I was going to put a tray a few inches above the water and put my eggs in containers with some perlite and the eggs lifted some on a plastic grate so its not touching the perlite, then put the lid on.

Does this sound like a good set up or should I worry about the water and humidity being too high?

I think using r.o. (reverse osmosis) water to heat the incubator unnecessarily complicates things. There is the obvious risk of electrocution, either of the eggs or of you, that you'll need to be careful to avoid. I would also be concerned about subjecting your heat tape to very high humidity for such a long time. In most incubators that I've seen, the humidity is confined to the plastic tubs you keep your eggs in. It never comes in contact with the heating element. Your heat tape alone should be sufficient to maintain temps.
