I currently have my fermenters sitting in my kitchen which sits at a nice 67 degrees. This was fine when I only had one going at time but when I added a second the SWMBO eyebrows raised a little but she said nothing. I'm wanting to add yet another small 2-3g carboy for cider soon and am concerned about the smell and pushing my luck too far.
So to avoid any "problems" I am looking to move my fermenters out of the kitchen and in to a home office I built in the garage. The office has an air conditioner to keep it cool during the summer but not a heater for the winter time (always just used a small space heater when I was out there). The office gets down in to the 30's during the winter time.
In doing some research a lot of people have a problem with cooling the fermenters but not seeing a lot for warming up the temp. Some suggestions I've seen are the fermwraps/brewbelts. Not sure if they can warm the 5G glass carboy up 30-40 degrees? Insulation box help? Also the idea of buying three isn't appealing.
Others use water baths and aquarium heaters. Not really an good option as I have paperwork & electronics in the room too).
The idea that I have is something like the son of a fermenter chiller with the chilling trays below. Instead of using ice to cool it down use a reptile heating pad to warm it up?
Any other suggestions? Sound feasible? Anyone else using brewbelts or fermwraps? TYIA
