But if you insulate without anything cool it down your temperature will get too high. At the height of fermentation your wort can warm up to 8*F higher than the ambient temperature. If you keep all of that heat in it will most likely get up in the 70's in the chamber.
Also, keep in mind that large volumes of water take a long time to change temperature. Do a search for "swamp cooler" in the HBT search bar.
I mean that 62 is on the low side according to the temp range printed on my fermometer. I am not talking about ambient temperature, I'm talking about what I read on my fermometer which, from what I have read, is very close to the wort temperature, give or take a degree. I plan on building a thermowell when i get my steel tubing so I can tell exactly how internal wort temp compares with the fermometer.
I use a swamp cooler to keep my lagers down about 50, then I move them into my converted freezer. But I am not concerned about cooling so much as maintaining warmth.....just enough warmth, not too much heat.
However, as you stated, 62 is not a terrible temperature and lots of people would love that so perhaps I'll start worrying about temperatures if it gets below that, and that seems unlikely at this time of year.
