If you're using a pot, you could put it on one of those electric warmer plates. If you should have one. I'm all about using what you got before buying stuff.
I've seen people use crock-pots with manual temp control (off-low-high) for keeping jars warm. They use a separate controller with a temp probe and an outlet. You plug the crock into the outlet on the unit, and the unit turns the power on and off when it needs to. You can get things like that from pet stores for reptile tanks or hydroponics shops.
For my first rig I was using a medium sized plastic cooler. Put my 3 jars down in it and I'd warm up kitchen towels and stuff around jars a few times a day. This wasn't very productive though. Also, you'd need to keep the lid shut to keep the heat in, which keeps fresh air out, and CO2 in as well.
I added an aquarium air pump I had as an extra to the cooler. I put it in the bottom of the cooler with the hose going out. Since CO2 is heavier than air, the pump would dump the CO2 outside the cooler instead of it pooling inside.
This kept my air good, but the pump didn't generate enough heat to warm the cooler at all; as I was hoping it would provide as a secondary benefit.
I was going to add a night light to the cooler, but in the process of searching for it, I found my aquarium and it's heater. Decided to go that route instead.
I do still use the cooler though. That's where I put my bottles after I've filled them to sit for a 2nd ferment. If one pops, it's contained in the cooler.
Grab a couple beers and start digging around your place. With a little ingenuity and liquid courage, you might surprise yourself with what you can come up with!
