One aspect of gas fireplaces that many people find extremely attractive are the optional accessories available. These include:
Fans: A small electric motor operates a quiet and powerful circulating fan for better heat distribution. Some units have a fan and switch built right in, others offer the fan as an accessory that can be added at a later time.
Thermostats: A very popular option is thermostatic control, which turns the fireplace on and off at preset temperatures, like a conventional furnace.
Remote control: For the dedicated couch potato, some gas fireplaces are available with an optional remote control. The remote can be used to turn the fireplace on and off, regulate the flame height, and control the activation and speed of the circulating fan.
Logs: With most companies, you can chose the type of "logs" the fireplace has -- oak, birch, etc. Gas fireplaces utilize a special type of virtually indestructible ceramic log, and many of the ones in use today are surprisingly realistic in appearance, both when the fireplace is off and when the logs are "burning" -- right down to glowing embers in the bottom of the firebox.
