Default C41 rinse water temp

Iím soon to process my first sheets in c41. Quite daunting! This will be in a jobo atl-1000 automated processor. Everything is being tested and seems to be good except the rinse water. I have two options, mains feed with thermostatic control or a tank/heater/pump combo to feed tempered water at the critical moment.

Iíve been looking at the equipment for either and have seen some instantaneous hot water heaters that can be set to 38įC. But they arenít 100% instant. So initially water will come through the pipe for a second or two much colder.

So my question, in order to avoid reticulation or other issues, would an almost instantaneous water heater be sufficient or must every single drop of water be at 38įC?
