The heater/defroster in our cars is really "always on" to a certain extent, even if you don't have the fan blowing. You turn it "off" by closing the little vent flaps -- but the heater is still pretty hot. Here's a shot of it so you can see what I mean. In the summer you don't want any heat coming out of your heater, so the best way to really turn it off is to shut off the hot coolant supply to it. The next picture shows the shut off valve to the heater hose on the manifold (big red arrow). Below that is a shot of the nicer, "classy reservoirs" -- the BMW reservoir will work just as well, but doesn't look as cool.
