This might be a dumb question, but what is the technical explanation as to why an electric space heater (two prong) plugged into an outlet (also two prong) would cause the heater plug and outlet itself to show signs of overheating? That is, the heater plug shows signs of slight melting of the plastic and scorch marks on one prong, and the receptacle looks a bit scorched as well at the same corresponding location. The outlet is as old as the house...perhaps 50 to 60 years, and the heater is almost brand new. The heater has a max power of 1500 watts, and the outlet, though old, should be able to accommodate a 1500 watt load even if its only a 15 amp circuit, yes? Is it maybe because the old outlet has lost its ability to "grip" and so the metal contact area has decreased? I plan on replacing the outlet, but would like to hear the voices of experience on this. Would it be a good idea to put a new plug on the heater as well (it still seems to work OK as-is).
