Hey Yves,
If you are religious about the daily water changes then you probably would be ok, however, chlorine and chloramine both gas off from city main water in 24 hours in a volume of 20 liters, after that it could be fair game for bacterial growth. In smaller volumes the off-gassing would occur much faster. Does it mean the chlorine and chloramine are still present and doing there job? Heating water is known to accelerate the off-gassing process , but if it is not done to boiling temperatures will still leave bacteria in the water.
As you would never bring a UTH up to those temps, it stands to reason that the temperature is in the ripe zone for bacterial growth It's hard to say, but what if the snake decides to defecate or urinate in the water and then soak in it? Obviously you can't stop them from doing this but if the temps are up, what true effects are occuring on the snake.
Misting and fogging and Spaghnum Moss are all methods and I use them all when needed. I suppose the other thing you could do is deny access to the heated water by putting a screen over the bowl as an added precaution.
Invictus: Mold wouldn't be the only issue, it's the micro-organisms to be concerned about and evaporation would still occur even in the cool zone as that temp would be normally around room temp or slightly higher.
Until I feel comfortable doing otherwise, I'll stick to the "better safe then sorry" method, with cool water and regular poop and scoop and daily water changes. There's my .02
