I will be buying a chest freezer to use as a fermentation chamber and I was just window shopping for temp controllers. Is it worth getting a two stage controller for both heat and cool. My thought was I could use a reptile heater or lamp to generate heat and obviously the freezer for cooling. My concern is that my basement is usually around 62* in the winter and I struggle to get my beers up in temp in the winter.
If I get a single stage controller I’m worried that if I start it off with heat and am away from home for the day and my fermentation takes off (I’ve had jumps of 10 degrees while I was at work before), then come home and switch it to cold, those temp swings will probably piss off the yeast.
But at $150+ and the cost of a reptile heater, that’s a lot of dough. Am I worrying too much or is this a valid concern? Does anyone have any experience with a setup like this?
