55 gallon tank temperature issues?

Okay, im cycling my tank, checking my temps. I have a marineland 200 watt heater on 1 side, same exact 200 watt heater on the other side, both set at the exact same temp. 82 degrees. I have 2 hang on back filters, and a power head so theres plenty of circulation of the water. On my thermstats one side is showing 82 the other side is showing 80 degrees. What the hell is going on. Both thermostats are placed in the exact spot on opposite sides, both heaters are placed horizantly a few inches on away from the gravel. Why am i getting 2 degree loss on one side???????????

Update:

it is about 6 feet away from the window,(third tank, running out of room) but i do not feel any draft and i have curtains

Update 2:

forgot to say im on my thrid set of thermometers, all reading the same

    What's going on outside of the tank? Is it possible that a window, or a door is creating a draft?

    Have you tried taking readings with another thermometer to see if one is faulty?

    I would just stop worrying and say your tank at is 81 (+/- 1deg).

    The fish need a temperature in their natural range, and reasonably steady. But a couple of degrees either way make no difference. Think about fish in the wild, some days the sun shines, some days it doesn't, they deal with it.
