Strider,
You might want to consider insulating the bottom of the water heater.
To my knowledge, the water heaters have some kind of insulation on the top and sides but nothing on the bottom.
Hot air rises but radiation goes in all directions.
If you could slip 1/2" of blueboard EPS (or maybe some of that aluminum bubble wrap) under the heater it might be your cheapest, easiest, most effective insulation, especially since your basement temps are as low as 16 degrees and your water temp is as high as 110, that's a pretty big delta-T.
I just
found this:

If you want to add board insulation to an existing unit, it might be a bit of work. Depending on the hot water heater, you may have to unhook your unit, drain it and reinstall it, but you'll save 4%-9% on your water heating bill. That's the same amount of energy saved by an exterior insulation jacket.

Just a thought...
