Turn the defroster on high heat to ensure that the coolant is flowing through the heater core. Monitor the coolant level in the reservoir ..don't let it go dry. Common after replacing any of the following the radiator, water pump, heater core, or thermostat.

Either trapped air or partially clogged heater core. I've had a few do that
