What's AFUE?

Throughout these pages you'll see references to percentages - 80%, 95%, etc. These numbers are referring to the Annual Fuel Utilization Efficiency rating, or AFUE. The AFUE for a particular furnace is measured in standardized tests developed by the Department of Energy, and shows how efficiently a particular furnace turns fuel into heat for your home. The higher the number, the more efficient the furnace.

Older, inefficient furnaces allow much more of the combustion heat to escape up the chimney without actually heating the house. Newer furnaces capture more of that "waste" heat and send it into the house.

 

Heating

While Rheem makes dozens of models, (and I'll be perfectly happy to sell you anything from their catalog), I've chosen a limited set of Furnaces that I think work particularly well in this part of the country. Like the Air Conditioners, they're all tough and reliable, and specially selected to meet common price points. I always try to encourage my customers to buy the most efficient furnaces in their price range because I know that they'll continue to save money for many years, but I think you'll be happy with my prices no matter what your choice.


Rheem 95% RGRM

While far from being the most expensive unit in their catalog, this furnace from Rheem's Classic Line provides a nice balance of proven technologies, comfort features, and high-efficiency, adding up to what I think is a particularly good value.

Two stages of operation Rheem RGRM Furnace( 70% capacity for low-heat and 100% capacity for high-heat) save energy and maintain optimal comfort level.

Variable speed blower motor technology provides ultimate humidity control, quieter sound levels and year-round energy savings. This same feature also works with your Rheem Air Conditioner to provide perfect humidity control in the summer.

IN-SHOT BURNERS
The natural (or optional LP) gas is ignited by the direct spark ignition at the in-shot burners. The in-shot burner's shutter free design requires no adjustments to regulate the air/gas mixture.

DIRECT SPARK IGNITION
Direct spark ignition is an extremely Reliable and efficient way to light the burner. And it eliminates the need for a standing pilot. For added safety, the remote flame sensor constantly monitors the burner flame to ensure it is operating as it should.Energy Star

Rheem 95% RGRC

This system still has the great efficiency rating, so it qualifies for the rebate, but it's much more of a basic system, with single stage burners and a single speed fan. It's a good basic workhorse.

Rheem 80% RGPR

Not long ago this was considered quite a high-end furnace and is loaded with top-of the-line features, but the new 95% units in the line have now taken it's place. You probably won't be able to find a furnace with this many features at this kind of price for much longer. This model is a good buy.Rheem 80% RGPR

The Rheem Classic Plus®
Super Quiet 80 Gas Furnace has two stages of heating to save energy and keep your home at its comfortable best. Most furnaces are either “off” or “on” at 100% capacity, no matter what your heating comfort needs may be. The Rheem Classic Plus Super Quiet 80, however, operates at 70% and 100% capacity. Most of the time, this furnace operates in its energy saving “low-heat” stage to deliver a gentle and steady flow of heating comfort. On the coldest days, when you need more heat, the furnace automatically switches to “high-heat” stage to deliver the maximum heating comfort. The temperature of your home stays at the comfort level you select – wherever you set the thermostat.

 

 

 


Rheem 80% RGPQ

This furnace has quite a few nice comfort features yet is easy on your budget

To help improve the sound qualityRheem RGPQ of the Rheem Classic Plus Super Quiet 80, we re-engineered the door and top-plate to provide a sound barrier between the furnace’s operation and your home.

The integrated, two-stage control board directs activities of the gas valve and blower to efficiently keep your home at its comfortable best.

The two-stage gas valve adjusts the flow of gas to the burner, providing “low heat” and “high heat” as needed for maximum fuel efficiency.

Direct spark ignition is an extremely efficient way to light the burner while eliminating the need for a standing pilot. And for added safety during operation, the remote flame sensor constantly monitors the burner flame to ensure it is burning as it should.

Because the Super Quiet 80 two-stage usually runs at the lower speed, you will enjoy energy saving and operation that is quieter. Working in conjunction with the two-stage burner and the heat exchanger, this induced draft blower quietly pulls hot combustion gases through the heat exchanger and vents them safely outdoors.

A permanent, washable filter makes it easy to keep a clean filter in place. No more filters to buy or store. A clean filter helps your furnace run more efficiently and can improve the indoor air quality of your home.
