If you have a furnace that has seen more than 20 years of service, it\u2019s also time to get a brand-new unit. That old furnace is probably costing you too much money to run each time it comes on, and it may even turn into a safety hazard.<!--more--><\/p>\n<h3>The advantages of a sealed combustion furnace<\/h3>\n<p>There are many reasons to go with a newer furnace, but one in particular is that many modern furnaces use <em>sealed combustion<\/em> rather than <em>atmospheric combustion<\/em>. What\u2019s does that mean, and what\u2019s the difference?<\/p>\n<p style=\"padding-left: 30px;\"><strong>Atmospheric combustion: <\/strong>This is the conventional way that furnaces operate. To create combustion, these furnaces draw air from the inside of the house and mix it with gas from the burners. The air comes in through a grill on the cabinet of the furnace, and the exhaust left over after combustion is vented outside through a flue.<\/p>\n<p style=\"padding-left: 30px;\"><strong>Sealed combustion:<\/strong> These furnaces draw the air for combustion from the outside of the house through a plastic pipe. The combustion chamber itself is sealed off from the interior of the house.<\/p>\n<p>There are multiple reasons that sealed combustion is a better choice for a furnace:<\/p>\n<ul>\n<li>The furnace doesn\u2019t take away already heated air from the house.<\/li>\n<li>Since the furnace doesn\u2019t remove air volume from the house interior, cold and dry air won\u2019t rush in from outdoors to fill the space.<\/li>\n<li>Sealed furnaces lose much less heat during combustion, helping to increase energy efficiency.<\/li>\n<li>A sealed combustion chamber prevents backdraft problems that can lead to harmful exhaust escaping into the home.<\/li>\n<\/ul>\n<p style=\"text-align: center;\"><strong>For <a href=\"\/heating\/furnace-installation-replacement\">new furnace installation<\/a> in Springfield, VA, call on Oasis Heating, A\/C &amp; Refrigeration.
