I use an electric heating pad also, and it works fine so far.

That's all very interesting, but I neither have running water in my darkroom, nor adequate electrical supply. The enlarger and the heater take turns.
I'm going to try the heating pad, which I've tested, and it does not draw so much as to deprive the enlarger from power. Insulation on the little room should help a lot, and that's the next big step.
It all makes the idea of new canon 5D and an Epson printer so appealing... but I think I'll just grin and bear it. I have to admit there's been a lot of grinning in my darkroom lately.
I framed the print I worked on all week, and I see few more things I can do to bring that print to a more satisfactory conclusion. I'm being really good and sticking with it, because the back log of negatives I want to apply my new findings to is growing.

Elias,
I am a bit surprised that my methodology has not been offered yet... Do you not have a wet darkroom? I use (much) larger tray, on a riser so that it is a couple of inches higher that has temperature controlled water running through it with an outflow tube that dumps into my wash tray. Not only does my temp stay where I want it so does my first rinse/holding bath. I use this method for both printing and my 8x10 sheet film processing. It takes very little water flow and very little practice to set the incoming temp at the place where it keeps your developer at the proper temp and still provides a good rinse/hold temp. (This is much more critical for film than for paper.) 
Of course if your not using a wet darkroom my condolences, I've been
spoiled, the method can still be employed using a closed loop system with a small aquarium pump circulating water with a "coffee or tea warmer". Even had one set up with a large bucket as his holding tank and then used an old 
electric skillet, thermostatically controlled by virtue of it's design
nearly submerged in the bucket. Adjust the dial on the skillet to keep your water temp where you need it to keep you dev. warm and cozy! Some heat will be lost to the room which I doubt you will mind and truth of the matter is 
water is a better conductor than air so it will in principal be a more
efficient and manageable system albeit more convoluted to set up. Another 
plus is if your climate pushes in the other direction as it did while
working in deep east Texas for far too long you can COOL your chemistry as 
well!
