You’ve probably heard in Carnegie about the new lines of high efficiency furnaces being released by popular home heating companies, but what exactly is different about these high efficiency devices from your current furnace? Let’s take a closer look at what a high efficiency furnace offers and why it can save you money.
A high efficiency furnace uses familiar technology in a new way to reduce the amount of energy lost when combustion takes place. This means:
- Sealed Combustion – Instead of open combustion which allows heat to escape during and after the combustion process, a high efficiency furnace uses a sealed chamber with carefully measured and fed airflow to burn fuel and produce heat. Exhaust heat can then be recaptured and used to heat air transferred to your air vents.
- Two Stage Gas Valves – With a two stage gas valve, your furnace can respond to the temperature outside. There isn’t just one “on” switch. The furnace will regulate gas flow based on how much energy is needed to produce heat for your home. So, if there is a sudden burst of cold outside, the furnace will respond accordingly, but for most days when heating needs are low, it will use only the minimum amount of needed gas.
- Programmable – High efficiency furnaces are now programmable, meaning you can set specific time limits for operation, change thermostat settings digitally and inspect the device through an electronic read out. The level of control given to you by a programmable high efficiency furnace can greatly reduce gas or electricity consumption.
The real reason many people are interested in high efficiency furnaces is that they are so much less expensive to operate. Instead of costing hundreds of dollars to run through the winter, they operate the bare minimum needed to heat your home. Using up to 95% of the fuel they consume to produce heat and regulating gas to cut how much is consumed during milder days, these furnaces are built to save you money.
If you have an old furnace that chews through energy like nobody’s business, now might be the time to consider the benefits of a brand new, high efficiency model.
