Im trying to decide whether to put in a gas fireplace insert or freestanding stove about 1ft outside fireplace. What will give the "Most" heat and be the most economical to run. I do like the inserts but if they will cost me more to heat the same room than an equivalent free standing stove I would rather go with the stove. I know if I go with a cast iron stove it will radiate heat all the time even when the fire goes out for 10 minutes or so and the insert wont . Also looking for a insert or stove that has a built in blower that throws the air out in front so it will move air into another room. Any suggestions ?
