Sounds like you have a basic recirculating heater. Not the greatest heater but if it's not a daily driver or not driven much in the cold it is a more desirable option because the deluxe heater take up a lot of space under the hood and are ugly (my opinion). If you get rid of the basic heater there is some demand for others that might want it in order to keep their engine compartment cleaner.
