proper gas fireplaceGas fireplaces are a great addition to any room in the house and a favourite addition of many homeowners. But, how do you choose the right fireplace for your room?

You can use either gas or propane to fuel your fireplace and both will give you from 80 to 97% efficiency rating. Gas is the cleanest because it has fewer impurities when compared to other types of fuel and it is better for the environment.

Propane is an odorless and environmentally friendly fuel but it does have a smell, which may be off putting to some. The 1990 Clean Air Act did approve propane as a clean fuel for fireplaces.


Direct Vent

Direct Vent fireplaces are factory built with sealed glass doors and they operate by taking in oxygen from the outside through one pipe. The by-products from the gas fire are exhausted back to the outside from another pipe. Direct vent fireplaces may have a vertical vent that exits through the roof or it may have a horizontal flue that goes right through the external wall. A zero-clearance direct vent is well insulated and are much more convenient as they can be used nearly anywhere in the house regardless of space. Direct Vent fireplaces need no electricity to operate and if a blower to spread the heat is required, a battery-operated system can be installed.

B-Vent or Natural Vent

B-Vent or Natural vent fireplace do not have a sealed combustion chamber and operate by using the buoyance of hot gases to vent effectively. They must be installed either with an existing chimney that meets the local building code standards or they can be installed using a B vent which is a vent pipe that must be installed to the same parameters of a masonry chimney but can be enclosed in combustible material. They draw oxygen necessary for combustion from the area surrounding the fireplace. The combustion by-products or flue gases are hot and naturally rise up through the chimney which provides a route for these hot gases to escape from the house. As the fireplace continues to vent these flue gases up the chimney, the walls of the chimney heat up, which allows the flue gases to retain more of their temperature and buoyancy thereby increasing the speed with which they exit the chimney.
