No heat

I am new to ford. That being said I have a 1998 f150 that has no heat. It is not even warm almost as if I have a.c. on. Intake hose gets somewhat warm, outlet hose does not even warm up. I would love some advice.

Things I have changed and addressed:

Thermostat is new

Water pump is new

Heater core is new

Had electrolysis issue, taken care of

Leaking intake tube replaced

blend door, cabin air door and mixer door working.

All actuators working properly

Flushed cooling system

Fan is working

Burped the system

Still no heat.............

Update:

Turns out that the water pump was broken the propeller inside had become completely disconnected from shaft. Which was throwing me off because still had circulation. Turns out it must have been making just enough of intermediate contact to give enough flow to keep engine cool but not enough to get coolant to heater core.

A broken new pump? That must have been a cheap pump. Water pumps usually leak, not a broken shaft, that's pretty rare.
