Understanding Furnace Types
Navigating the plethora of furnace options can be confusing and stressful. Use this guide to gain a better understanding of the differences between furnace types so that you can more easily understand the options for your Littleton, CO, home.
Most homes have either a fuel-burning furnace or an electric furnace. Industry experts agree that electric models are usually the most expensive to run, in part because of the cost of electricity. For fuel-burning models, the two popular options are natural gas and propane. If you live in an area with natural gas service, this is the option you’re most likely to choose. Propane is usually used when you need to store your fuel because you don’t have a utility serving your home.
Aside from different fuel types, there are three primary differences in the technology you’ll find inside a furnace. These technologies focus on the heat exchanger, burner, and circulating fan.
Condensing furnaces have two heat exchangers. The first is like the heat exchanger in any other furnace. The second heat exchanger extracts enough additional heat that it causes much of the residual flue gases to condense. Condensing furnaces offer efficiency ratings as high as 98%.
Multi-Stage and Modulating Burners and Fans
High-efficiency furnaces, such as those with an Annualized Fuel Utilization Efficiency (AFUE) rating of 90% or more, use a combination of multi-stage or modulating burners and fans. Multi-stage and modulating burners allow the furnace to produce the exact amount of heat needed for that heating cycle. Multi- or variable-speed fans control the speed of the circulating fan, allowing it to run at a lower capacity most of the time. By running at lower capacity, your furnace consumes less fuel and energy, reducing your heating expenses.
