Which Furnaces Are Energy-Efficient?

If a furnace loses heat or wastes heat, it will use more energy to warm your home. Some furnaces lose heat through walls in the cabinet, and Rheem’s entire line of state-of-the-art furnaces significantly reduce heat loss. Gas furnaces emit a constant, wasteful draft of warm house air when they are not in use. The gas furnace sends warm household air up the venting system to the roof. Rheem products have an induced-draft fan that works with a hot surface igniter system to draw hot gases through heat exchangers at a controlled and constant flow. The draft blower will stop as soon as the burner turns off, allowing the heating air to remain in the system.

Pilot lights can also be wasteful. Many Rheem furnaces have an electric ignition that eliminates the need to have a pilot constantly on. This feature alone can increase efficiency by up to 6 percent. Combining this feature with an induced-draft fan can increase furnace efficiency by more than 20%. Most gas furnaces allow warm air to naturally rise, allowing combustion byproducts and gases to be vented. However, proper venting may be limited by blockage, malfunctions, or other reasons.

Rheem’s induced-draft blower keeps a constant draft through heat exchangers, ensuring the proper furnace combustion chamber venting. Rheem has a pressure switch that continuously monitors venting. If it detects a restriction in vent flow, it will shut down your heating system to ensure your safety.

The most efficient furnaces harness the heat of hot vent gases, which can reach temperatures up to 500 degrees. High-efficiency furnaces are generally more expensive, but they can save you money in the long term by having lower operating costs. These furnaces are more efficient due to today’s consumer demand for efficiency.

Which furnaces are better?

You should look out for heat exchangers that resist corrosion, induced draft blowers, pressure switches, and an insulated blower chamber, which reduces operating noise. Solid warranties back the work of the best brands is a hallmark of quality. Rheem furnaces have one of the best Limited Lifetime Heat Exchanger Warranty.

Did You Know?

One in four furnaces in U.S homes today are more than 20 years old? Older furnaces were not built with the same energy-saving technology as today’s products. Your older furnace could be costing you hundreds of dollars a year between maintenance needs and energy usage.
