I would first burp the hoses going to the heater, maybe removing the hoses as close to the water pump as you can, maybe tie the ends up above the radiator, then take a water hose & a nozzle & put the nozzle into the return hose & turn on the water valve on to a low pressure, until clear water comes out of the supply line.
Then pinch off the heater hoses with either hose crimps or needle nose vice grips that have tape wrapped around the metal teeth.
Then slip the heater hoses back on & tighten them back up.
That should insure that no air is in those hoses or the heater.
If that does not get rid of the air bubbles, then you have a leak somewhere. In that case i would think about using DYE to find the leak
Thanks for the response, Do you know which hose is supply and return? and which fitting it corresponds to on the water pump? I have also heard of unhooking the return line and waiting for it to push coolant out. This will be the next thing we try. I also never lose coolant on the ground once the system is closed so I'm not sure where a leak would be
