A ventless gas fireplace is a fireplace option you have if you'd like to enjoy the heat and warmth of flickering flames but your home doesn't currently have a chimney and you don't want the cost of installing one. Even if you have a chimney, you may like the idea of a fireplace in the bathroom, midway up a wall, or tucked into a corner, places that are traditionally not accessible via chimney. The cool thing about ventless gas fireplaces is they can be installed just about anywhere.
To help you decide if one is for you, let's take a look at some of the pros and cons as well as the price:
Ventless Gas Fireplace Advantages
- Since they don't require venting to the outside of the house, they are easier (and less expensive) to install than regular gas units or traditional wood fireplaces.
- Today's models are very fuel efficient, with 92%-99% of potential heat converted into usable heat.
- Ventless units are designed to produce a hot flame, which results in almost full fuel combustion, a benefit that reduces the amount of carbon monoxide emissions and soot produced.
- Ventless gas fireplaces are considered safe for homeowners because they include an oxygen-depletion sensor that turns gas off before carbon monoxide reaches dangerous levels in the room.
Disadvantages of Ventless Gas Fireplaces
- A big downer is that in some states, ventless units are banned because they don't meet all building codes.
- There are debates on the effects on indoor air quality. While manufacturers say their units meet or exceed all indoor air-quality guidelines, some people worry about fumes vented into the home as opposed to outside.
- Water vapor from the fire is vented into the home, which may cause condensation on windows, or in the long-term mold/mildew issues.
Cost of a Ventless Gas Fireplace
While costs, of course, vary a lot from model to model, the general range is $800-$2,000 installed (gas-line work not included in estimate).
