radon fan air supply
I use a radon fan system to draw air from beneath basement floor slab. It really vents a lot of air. The make up air is coming into the basement from who knows where. It's making the basement very cold. Should I install a direct air supply under the slab from the outside? Other ideas to get radon out and keep heat in?

Howdy, is the fan sucking the warm air out of the basement? How was the fan installed to get under the slab?. Perhaps to much air is being moved, smaller fan? Finished basement?
