So if your goal is to actualy HEAT something, TEC is a good way to go?

Absolutely, I have tried to explain this to many people who see TEC's as a
miracle solution for their cooling problem.  My first PIC project was a PID
controler that used a TEC to wavelength stabilise a laser.  A big problem
was the huge efficiency jump when switching from heat to cool, the loop
gains had to be modified depending on direction of heat flow to obtain the
fastest and most stable response.
