Answers :

Yeah you probley have air in the coolent system try letting it run untill the temp is about 195 degrees and then cut it off lwt the water **** down and out mor in and do it over untill you got heat
Remove the cold line see if there is return flow the heat you feel could be just radiant heat.if you have flow might have been air bound. if not check heater core could be plugged with rust etc. or switch lines reverse flow to get it unclogged.
