Furnace technology has changed a lot over the past decades. Efficiency was not a huge concern in years past, and it is not uncommon for older furnaces to be grossly inefficient. If you are sick of paying too much to heat your home, you will likely need to update your furnace in order to make paying to heat your home more manageable. As far as efficiency goes, you can't get much better than a condensing furnace.
What Makes Older Furnaces Inefficient
Older furnaces have a few components that limit their efficiency. For starters, an older furnace will use a pilot light to ignite the fuel flowing into the burner. A pilot light is a constantly burning flame. To keep a pilot light burning all the time for the length of the heating season, you end up using quite a bit of fuel.
The ignition system is not the only problem with older furnaces. When you burn gas, you create exhaust fumes. Exhaust fumes have to be vented out of your home because they are potentially lethal. Older furnaces solve this problem by allowing hot exhaust gases to escape out of your home through a vent pipe. This venting system is effective, but the heat in the gases that are vented out of your home is simply wasted.
What Makes a Condensing Furnace Highly Efficient
Newer furnaces make improvements over older furnaces to improve their efficiency. For one, newer furnaces will use an electronic ignition system to ignite the fuel flowing into the burner. This means that you don't have to worry about wasted fuel. Furthermore, a condensing furnace will extract so much heat from the exhaust gases that they condense to liquids and have to be drained out of the furnace through a drain pipe.
Condensing furnaces are highly efficient and will help to keep your heating costs down. The best condensing furnaces will have a multistage motor that will make it so that the motor does not have to run full speed all the time. By allowing the motor to run more often but at a lower speed, you can further increase the efficiency of your furnace. While you will end up paying a lot of money for a new furnace, you can make up the cost of the new furnace simply in the savings you will find in your heating bills. A new furnace through a company like Advanced Appliance Service Inc is a good, cost-saving purchase.
