Sounds like the thermostat is shot. Try changing it with a good quality one. Should open up around 190 degrees. Also check to make sure the radiator coolant is at the proper level. Low coolant will also affect the heat.

Forgot a simple thing to check! Make sure the radiator cap is in good shape as it needs to hold the pressure for the system to work!
