Question: Hi. We are going to be installing a free-standing gas stove in our basement. We have a main heat source (oil furnace), so this will be partly for ambience and partly to take the slight chill off the air in the basement (basically a below ground basement). Some stoves have a variable speed fan as standard equipment, and some have it as an option. We have heard from various sales people differing stories about the advantages/disadvantages of having a fan. If the power goes out, can you still use the stove which has a fan, or does a fan block the natural convection of the stove? In a stove without a fan is the convection and radiant heat enough to take the chill out of the air in a basement where the area is 800 to 1000 square feet? Thanks in advance for your help in this matter. Answer: There is really no disadvantage to a stove that comes standard with a fan. The natural convection still works well. On the other hand, gas stoves without fans work very well and can easily take care of the space that you describe. Some stoves publish their heat outputs both with and without the fan. In these cases, the heat output is often very close...usually within 5-10% with/without the fan.
