Warm as I need it. Throw in another log. When the temperature drops to 31 degrees, the natural gas comes on and brings it to 45 degrees, then shuts off. Keeps things from freezing,when we are traveling. Costs about two hundred in gas on the average each year. plus I usually cut two cord a year, for the garage. This year I got another cord, from a broke kid, for 110$. I would have given him more, but thats all I had, when he came by the house. Hardest working young kid in the neighborhood.
