Suburbs near Warsaw are almost all connected to the gas network. I have many friends who own a house (and I also own a house at the border of the city) and I know nobody who would heat with coal. However the major problem is that gas is expensive and wood is cheaper. It is enough that one house in the neighborhood is heated by burning wood and everybody can smell it. The situation is also much worse in small villages far from Warsaw.
