#119128 - Valve in the outlet
Responding to: ???'s previous message
Erik said:
"mounting the transducer very close to the heater" will give all kinds of other problems such as transfer from thye heater, not just the water.

I would add a valve in the outlet shunting wrongly controlled and may be dangerously hot water arround the user to drains. This would mean a second and fast acting temperature sensor near the outlet.
Also, what about permanently mixing a bit cold water to the output, like having a constant resistance in parallel to a pot? Would this minimize the regulation spikes.
