Regarding the heater - how critical is it that the rest of the chemicals are of similar temperature as the developer?
According to publication J-39, the developer is the most critical, and should stay within +/- 0.5 C of the target temperature. The bleach-fix has a tolerance of 6 degrees, in comparison.

That said, even though my temp was around 28C, I'm pretty sure it wasn't stable to the half degree as per Kodak's recommendations. However, like everything else, it's not because you're out of bounds that things suddenly stop working. They might just be less repeatable, meaning that Kodak can guarantee their results within that interval, and take no responsibility for anything happening outside of it.
