As of January 2016, reviews regarding gas fireplaces say they are attractive, provide sufficient warmth and are relatively easy to install. One reviewer at Wayfair's website says that Napoleon's Vent Free Gas Fireplace should save money on heating bills and that the well-made product runs quietly.
At Home Depot's website, consumers find that Pleasant Hearth's Vent-Free Dual Fuel Fireplace is able to heat a large area. This fireplace runs on either propane or natural gas. However, a blower is sometimes too loud. An Amazon.com customer states that this fireplace heats well but, because it is vent-free, requires a large space.
