I would like to know what to do to make my open fireplace , that is my main heat source, more efficient . #green

I have an open stone fireplace. When it was built the builder made it so that there are open vents on the bottom in the stone and the inside of the fireplace is lined with metal which at the top where there are more vent holes there is a metal insert with 3 circular vents. The idea is that the cold air goes up and then out through the top. For this to be efficient I think I should use a blower. What kind would work? Any suggestions at all would be great. It is our main heat source for the house. I thank you for any help in advance !
