TECs use far more power than compressor based systems do. Their COP (Coefficient of Performance) is abysmal compared to compressor systems. The COP is very basically a measure of how much heat is moved for a watt of supplied electricity. The COP of a TEC based system is around 0.4 to 0.9. That means that 1W of electrical power moves between 0.4W and 0.9W of heat.

Compressor based systems usually have a COP in excess of 1, meaning that putting 1W of electrical power in moves more than 1W of heat. Well designed systems can reach a COP of 9, meaning that 1W of electrical power moves 9W of heat.

So, a well designed TEC system needs ten times as much power to acheive the same results as a well designed compressor based system!
