Both heat pads are the exact same size and brand

I heard though that it doesnt matter on the size of the UTH's unless they are going over the power limit of the thermostat?
When you say in the middle of the heat pad do you mean between the two of them or in the middle of one? If they are truly identical, I'd place it in the middle of one and the other should pretty much match it.

Heat and brand of the UTH definitely matters, as they are heating different amounts of space with the same amount of power and therefore going to heat faster/slower than one another.

Keep in mind also, proximity of items such as the water dish inside the tank may also affect heating efficiency slightly.

Oh, and what are you measuring your temps with?
