I'm doing a rebuild of my silvia today, including adding a PID and maybe insulation. I'm getting mixed info on the topic of insulation .
I see a PID as a "learning" box and should work perfectly given then parameters. I can also see that a machine may be less capable of "shedding" excess heat when the boiler gets above optimum temp. However, surely:
1) a PID should never allow the boiler get too hot. It should raise it to max temperature at exactly the right speed to not overshoot. If it never gets too hot, why would it need to shed heat?
2) a boiler might go below temperature as the shot pours, and insulation will help warm it up faster
