fresh rebuild heater not working

Flush out your heater core. It's probably clogged. But don't use high pressure!

Could be a clogged heater and/or the system has not be completely bled. Especially since one of the hoses to the core sits far higher than the engine and radiator. Possibly a t-stat stuck open as well.
