Hi Brian1, interesting you should say that. I actually thought I was helping to preserve the life of the unit by doing this, by not working it so hard to get it up to temps of 175 to 185. When I do this, I just give it a boost to get it up to cooking temp more quickly. For example, if I am want 175, I watch the temp on the Anova closely, and I turn off the burner completely once the temp hits 168 to 170. I have an electric radiant glass cooktop, so there is no heat or flames creeping up the side of the pot. I wouldn't do this on a gas stove, the hot air would roll off the bottom and up the side of the pot right onto the clamp. And with an induction stove, the metal parts of the Anova would essentially lite up and overheat. Might really mess with the electronics too. I guess Anova probably says not to do this because the typical Anova customer would have a gas or induction stove.
