The cost to heat your home with natural gas depends on how cold the winters are in your area, how insulated the home is and what size of home you live in as well as how often you use the furnace.
My home is around 1,600 square feet and during November and December the cost to heat my home with natural gas is $150.00 per month but it goes up to $200.00 per month during January and February when the weather gets much colder and the furnace has to run more often.
Still that's not too bad of a price to stay warm.
Natural gas as of now is the most efficient and cheapest heating option to heat your home in the winter.
