There are three different styles of gas fireplaces: the direct vent model, the top vent design, and the vent-free model. The direct vent gas fireplace uses two vent pipes that lead directly to the outside. One pipe uses combustion air from the outside while the other vents the exhaust gas. The top vent gas fireplace design can be installed into existing fireplaces and uses the metal or brick chimney as the exhaust vent. The combustion air for top vent fireplaces is drawn from inside the home while the chimney vents the exhaust gas. The vent-free gas fireplace model uses no exhaust vent. This style includes an oxygen-depletion sensor that turns off the gas if it senses a dangerous lack of oxygen inside the house. While fireplace manufacturers claim that vent-free fireplaces burn clean, are energy-efficient and dont threaten indoor air quality, be aware that a number of states do not permit the installation of vent-free fireplaces. In the New England states of New Hampshire, Massachusetts, Vermont, Maine and Connecticut installation of vent-free gas fireplaces is permitted. Massachusetts has in the past not authorized the installation of vent free gas fireplaces for safety reasons.
The first rule for any fire to burn in an efficient way, is what type of fuel are you burning? For a wood-burning fireplace to burn well you need to burn good quality, dry seasoned wood. When you burn quality seasoned wood the fire will burn cleaner, hotter and increase your fireplace efficiency. You may say I am already using good quality seasoned wood to help my fireplace burn well, but I still want my fireplace to improve its efficiency. There are still several other things that you can do to improve the efficiency of your fireplace another 25% or more. Every and I mean every fireplace should have a glass-door installed on it, if only for safety reasons, installing a glass door is one of the best ways of improving your fireplace efficiency for a very small cost. You might be thinking that if I put glass-doors on my fireplace the heat will stay behind the glass and just go up the chimney.
If you decide that sitting next to the fireplace is the way to go, you will need to make sure you have enough chimney rods to span the entire length of your chimney. As you are sitting next to your fireplace, push your brush up through the flue. Continue to add more brush rods as needed until the brush is at the top of the chimney. As you pull the brush back down, you will need to make a back and forth motion to really scrub the creosote off the walls of the chimney. Be sure to shield your eyes, as some of this loosened creosote may fall into the firebox.
The best reason I have saved for last and that is, your fireplace is costing you heat loss all day and night even when your not using it. The reason is that your damper in your fireplace is not airtight they are made that way to maintain a certain amount of clearance even when they are closed. So If you have a fireplace that does not have a glass-door you are wasting energy, up and out the chimney. In this article its easy to see how you can get more heat out of your fireplace with just a few small changes, that will let you burn outside air instead of the air that you already paid to heat, and by installing glass-doors to stop heat loss.
