Fireplaces have always been one of the most popular features in a home and are even standard in many new homes today. Many people find them cost-prohibitive and so they look for less expensive alternatives. Vent-free gas fireplaces are  an option more people are considering. Because of their relative low cost, convenience, and ease of installation, they appeal to many who are on a tight budget. They are an excellent heat source as no heat is lost through a chimney or vent to the outside, but before considering a ventless fireplace there are some things that you should know.

Ventless gas fireplaces are not vented at all and the burned gases remain in the home. Any gas by-products such as carbon monoxide, carbon dioxide, and nitrogen dioxide will circulate in the air. Although minor, these gas by-products are still breathed by anyone nearby. Ventless gas fireplaces produce quite a bit of excess water vapor, which can lead to the production of mold, mildew, and dust mites. All of these things cause poor quality air and can increase health risks.

Vent-free gas fireplaces are not approved for use in many states. In states where they are approved for use, installation guidelines must be followed very specifically regarding their placement and use. Local building codes vary greatly in different localities so always check with the building inspector's office to be sure of the codes in your area.

Many vent-free units come standard equipped with a carbon monoxide detector and oxygen sensors. Both are designed to shut off the system if conditions reach an unsafe point or if there is some type of malfunction with the unit.

Experts advise that you not use an unvented fireplace for more than 4 hours in a 24 hour period. This is due to the fact that excessive use can cause increased levels of carbon monoxide, which can cause dizziness, headaches, fatigue, and nausea.

Though vent free gas fireplaces are technically safe and less expensive than most vented units, they may not be worth the possible additional risks. Do thorough research and then make the wisest decision for you and your family based on all the facts.
