Without adequate heat dissipation on the hot side, the module's efficiency drops sharply and it can overheat. Apply thermal paste between the module surfaces and any heat sink or cooling plate for best results.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can the TEC1 Peltier module be used for heating as well as cooling?\u003c\/h4\u003e\n\u003cp\u003eA: Absolutely. Reversing the polarity of the DC supply swaps which side gets cold and which gets hot, making these modules suitable for both cooling and heating applications in temperature-controlled enclosures, scientific instruments, and custom electronics builds.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What power supply do I need for these Peltier modules?\u003c\/h4\u003e\n\u003cp\u003eA: All three models operate at a rated voltage of 12V DC. For the TEC1-12705 you need a supply capable of at least 5A; for the TEC1-12706, at least 6A (to handle startup current); and for the TEC1-12715, a supply rated at 15A or higher.
