I don't know where you fly but here in Canada knowing when & how to use carb heat is vital; we fly in the carb ice range a lot, and in extreme cold weather carb heat it can actually cause carb ice formation by heating the intake air to the icing range. There have been several engine failures caused by improper use of carb heat- the driver applied heat and the engine sputtered (indicating the presence of ice), and then panicked and closed the carb heat.
