I just yanked the heater out of my Model 2 for reliability and weight. On condition inspection found one associated hose bumping against the muffler and was lucky that it didn't blow. The only time I have run the heater is in the summer for added engine cooling.
For the sake of reliability, there would be four less clamps and junctions if I went straight to the radiator from the engine with the hose if not for the aluminum pipe. So the question is this: Why does the design include an aluminum straight pipe heading to the radiator?

Jeff,
Normally it would be because the aluminum tube is lighter
than the hose. (It's also a little bit more reliable.) However if the
tube is short enough then the added weight of the extra clamps
overwhelms any weight savings.

That idea really appeals to me. I've also considered removing the carb heat system from my airplane for similar reasons. I've seen a few installations without carb heat and the clean simplicity of it really appealed to me. Recently, a small cylindrical spacer that separated the heat shroud around the exhaust pipe disintegrated from the vibration so I might actually do it now.

Alum pipe will also dissipate the heat more than rubber hose.
works great for me
