If the laws of thermodynamics state that no machine can be 100% efficient because some energy will be lost to heat, is it possible to make a 100% efficient heater?

Yes, and in fact, all heaters are 100% efficient. Some people may claim it isn't true, because the heater makes sound- but alas that sound gets muffled or dissipated at some point, at which time it turns back into heat anyway. However, a heater that circulates the air better will use less energy to heat an area because if the heat isn't circulated, the air around the heater will get really hot and only transfers through unforced convection- which doesn't happen very quickly or evenly.
