gas fireplace inserts

Gas fireplace inserts are used to convert an existing wood burning fireplaces (both pre-fab and masonry) to a sealed gas appliance. They consist of a gas log set installed into a steel or cast-iron heat exchanger and are usually sealed on the front with glass. Many of these units have fans to move the heat, and are also available with remote controls, wall switches or wall-mounted thermostats.


These gas inserts are much more efficient than the vented gas logs, and the sealed fronts (glass) provide an extra safety factor. Quality gas inserts can provide BTU outputs ranging from 10,000 to 40,000 BTU and burn at over 80% efficiency.


Because of the high efficiency (very little heat goes up the chimney), the installation differs from that of regular gas logs. The flue outlet on these inserts is usually a 4" round pipe, and it is necessary to line the chimney to the top with a Flexible aluminum pipe or a B-Vent pipe. This assures a good updraft for the chimney. Some newer units use two pipes up the chimney, one to bring in combustion air and one to send the by-products of combustion back outside.


Recently, a new breed of gas inserts have been developed that do not need a chimney liner. These units are built to be less efficient than the regular inserts, therefore throwing a bit more heat up the chimney. The chimney can therefore draft well without needing a liner.


If you like the idea of a gas fireplace conversion, and are looking for a unit to provide supplemental heating as well as the beauty of a flickering fire, check out the gas inserts on this site, or contact our sales staff at 607-936-HEAT.
