Heater Condensation trap problem

[GMCAMARO]

My condensation trap ran in a nice downward slope through my garage attic, until it exited my eve.
Then the pipe was vertical for 7 feet. At the bottom of the vertical run the pipe would form icicles and then fill the pipe with frozen water. So I changed the setup so that everything is inside the garage except the last inch which is outside. I used a 22.5 degree joint just inside the garage so the exit outside is running at 22.5. I appear to be having icicles forming again, how do I solve this issue?

Would probably be a PITA, but you could put a tee in and drain it inside the garage in the winter months and outside when its warmer. What about some of that electric heat wrap tape for water lines?

Is it possible to vent it into the vent stack for the bathroom? Just make sure that you have a trap in the line so you don't get odors into the heater from the stack.

Have you tried a larger pipe where it exits the garage? Larger pipe shouldn't let ice block the opening?

The vertical pipe from the eve was 1.25, the pipe from the heater, is .5 and it forze.. A current solution is to run all of it inside except the last inch. At the moment last night got down to 14 degrees and all today was below freezing and no ice has formed yet.

could you fab up a secondary route into a drum, and just empty it once every 2 weeks or so during the winter?

Obviously, any slow trickle of water out into sub-freezing temperatures is going to result in the water freezing up.

Only solution is to drain someplace where it is not going to freeze.

Wrap the outside section with a short section of self regulated plumbers heat tape and insulate it with closed cell foam pipe insulation. Have the tail of the heat tape stick out tight to and past the end of the pipe an inch or so so the water runs out of the pipe and onto the heated tail. No ice.
