The most important thing is the insulation.
Sleeping bag, bubble wrap, brew fridge, or anything else.
At this time of year, I almost always have 2 fermenters on the go wrapped with a single size sleeping bag zipped up. Perfect for size.
I also have them monitored with five temp probes. Why? Just for interest!
And with a room temp between 15C and 16C at this time of year, except in the evening when the central heating is on and it rises to about 18C, and a tiny bit of local heat overnight, the temperature of the liquid varies very little.
The highest, probably 21.5C might be when the fermentation is at it's most vigorous, creating it's own heat. The lowest maybe 18.5C after a very cold night and a finished fermentation.
If that is good enough for you any (small/tiny) heat source will do.
And you don't need an electronic second by second or minute by minute controller as long as you can do an hour by hour manual adjustment ...unless you want to, just for fun or interest or whatever.
It takes a decent bit of heat x time to move the temp of 2 x 23 litres.
Simply put, with an insulated fermenter and a small temperature difference, it is something you can do manually in the home. Cheap and easy.
