Electric heat pump water heating condensate drain

How is the condensate from a heat pump water heater supposed to drain? Can it be connected to the T &P drain? (course materials say no tees are allowed in T & P drain. ) It seems silly to expect 2 parallel drains doing the same thing right next to eachother.

No.

You answered your own question.
HP Condensate drains are regulated as to where they discharge to the exterior (urban configurations). T/P drains can not be modified. Just because you need a drain, you can not forgo the requirements of the drain you want to connect to just to save some pipe.

You can’t connect to the sewer vent or drain either, for the same reason.
