Condensers don't like heat no matter what they are made from. This was a problem back in the day of wax paper insulated condensers and has been a problem with mica and mylar materials as well. They hold up better with modern materials but excessive heat is still not a good thing. The blow proof types hold up well on cars with no heater but I don't know about those that have a manifold heater like the one posted. If I idle my model A too long in the south Texas heat, there is no telling what the temperature of the distributor gets up to.

There has never been a control valve installed and it seems as if all the control valve does in any of the applications I have seen is to block flow into the cabin. There is no "diversion" duct on the heater so it flows or does not.

IMO, Heat is always bad for electrics/electronics so trying to limit it if at all possible and Central Texas heat is what I'm dealing with so I understand what you are talking about!!
