No hot water is getting to the heater core. Heater valve and this ball valve is in place instead of aux water pump. I know for a fact that one or both of these devices are working because I am unable to get heat also. This is why this is such a mystery to me. I know there is no leak, the system was vacuumed and tested for 2 hours (1 hour vacuum , tested for 2 hours) so 3 hours total. I'm taking it to a mechanic tomorrow. Hopefully it's just low on refrigerant. Unless anyone has anymore ideas.
