The answer to this question depends on your needs and how you plan to use the fireplace. If you’ll be using it as a main source of heat, then ventless fireplaces are probably not ideal. For those who want their hearth area solely as an aesthetic addition with occasional supplemental heating or ambiance lighting, however, these units can work well depending on the design style that best fits your decorating scheme. Whatever choice you make about installing a gas versus wood-burning unit in your living space will also depend largely upon where you live; if there’s already central air conditioning present in the house and little need for additional warmth elsewhere (like during summer months), then having the extra heat in the living room may not be necessary. If that’s your primary area of concern, then you might want to opt for a wood-burning fireplace instead; these units are available with glass doors and panels that can help prevent excess heat from escaping into adjacent rooms.
