Anyone in the Sacramento/Tahoe area using SVO for home heating? email@example.com
I am not in your area but have heated 2 houses for the last 6 Illinois winters burning used veg in simple drip burner space heaters.
This links to the "Biodiesel for heating" discussion on this site, it has tons of info on many types of burners using used veg as there fuel.
