What are you using as a temperature sensor?
At what temperature do you need it to cool and what temperature do you need it to heat?
The effect of feedback voltages can be minimised by putting the thermistor output on the - inputs and add an inverter to one of the outputs or by ensuring that the feedback resistors are of a high value relative to the source impedance.
