Would you believe more than one-half of your home’s energy costs are linked to heating and cooling? That’s why it’s so important to have an energy-efficient HVAC system.
Furnace efficiency standards were last modified to 80 AFUE in 2015. AFUE, or annualized fuel utilization efficiency, calculates how effective your furnace is at changing natural gas into heat. An 80 AFUE rating means your furnace will expend about 20% of the fuel it uses while generating heat.
In 2022, President Biden proposed new energy-efficiency standards for residential gas furnaces that would substantially lower emissions, save customers money and encourage sustainability.
This proposal is projected to:
- Save Americans $1.9 billion annually.
- Lower carbon emissions by 373 million metric tons and methane emissions by 5.1 million tons over the next 25 - 30 years, the equivalent of what 61 million homes emit each year.
Starting in 2029, the suggested rule would demand all new gas furnaces to be 95 AFUE. This means furnaces would transform nearly all the gas they use into heat.
With these facts in mind, you may be asking yourself "what happens to my existing furnace"? For the time being, not much, as the proposed rule will not go into effect until 2029 at the earliest and does not affect furnaces that are already in use.
But if you’re going to be needing furnace replacement in Oxford soon, highly energy-efficient furnaces are ready and available. Discover how these furnaces can save dollars each month off your energy bills.
Guide to Condensing Furnaces
How Condensing Furnaces Work
A condensing furnace is a kind of heating system that uses a secondary heat exchanger to trap wasted heat from the furnace's exhaust gases. This decreases the amount of energy wasted, improves energy efficiency and lowers greenhouse gas emissions. It also requires less natural gas to produce the same amount of heat in comparison to other types of furnaces.
How Condensing Furnaces Differ from Non-Condensing Furnaces
The main difference between a condensing furnace and a non-condensing furnace is the condensing option's use of a secondary heat exchanger to gather any wasted heat from its exhaust gases, while the latter does not.
The life span of a condensing furnace is dependent on the brand, model and other factors. Usually, a condensing furnace should last between 10-20 years with proper maintenance and regular service. If your heating system doesn’t have regular furnace maintenance, the equipment may have a significantly shorter life span.
Why Condensing Furnaces Cost More
Oftentimes, condensing furnaces are more costly than non-condensing furnaces. This is because of their increased efficiency and the additional parts necessary to capture any wasted heat from its exhaust gases. The extra energy savings can frequently offset the cost of purchase, however, so ultimately, it may be worth investing in a condensing furnace.
Guide to Variable-Speed Furnaces
Variable-Speed Furnaces: The What's and How's
A variable-speed furnace can change its fan speed subject to the heating requirements of your [[location]] home. It operates at a slower speed until it senses a temperature decrease and then fires up to supply more heat. This type of system is much more efficient than standard furnaces, as it only consumes the amount of energy required to heat your home, and thus, saves you money on your utility bill.
The majority of variable-speed furnaces are condensing furnaces, although some are available in non-condensing models with lower AFUE ratings. In order for a furnace to be classified as a condensing furnace, it must be 90 AFUE or higher.
Do Variable-Speed Furnaces Run Continuously?
A variable-speed furnace doesn’t stay on all the time. Instead, it runs at different speeds according to the temperature in your [[location]] home and the amount of energy it requires to sustain that temperature.
When too much energy is necessary to maintain your chosen temperature level, the furnace will increase to a higher speed to handle the demand. This allows for more efficient heating and cooling in your home while also providing quieter operation.
Guide to Two-Stage Furnaces
Two-Stage Furnaces: What They Are and How They Work
A heating system with two settings of operating - high and low - is called a two-stage furnace. In the low stage, the furnace runs at a reduced capacity in order to maintain a desired temperature within your home more efficiently. During the high stage, the furnace will operate at full capacity to fulfill demands for increased warmth or cooling. With a two-stage furnace, you can realize improved energy efficiency and uniform temperatures in all areas of your home.
While two-stage furnaces are extremely efficient, not all systems are condensing furnaces.
Does a Two-Stage Furnace Run All the Time?
A two-stage furnace should not run constantly. In the low stage of operation, the furnace performs at reduced capacity in order to sustain a desired temperature more efficiently within your home. When more warmth or cooling is needed, the heating system will flip to its high stage and operate at full capacity. As a result, two-stage furnaces are able to help reduce energy costs as it is not operating continually.
Contrasting Two-Stage and Variable-Speed Furnaces
Two-stage furnaces have two stages of functionality, low and high. During the low stage, the furnace performs at reduced capacity to help maintain a desired temperature within your home. When more warmth or cooling is necessary, the furnace will shift to its high stage and operate at full capacity.
Variable-speed furnaces can function at multiple speeds in order to maintain a precise temperature within your home. So, if you have more options for temperature-settings, you also have more flexibility for heating you home, which also means more savings on energy bills.
Differences Between One- and Two-Stage Furnaces
One-stage furnaces have a single stage of performance and operate either at full capacity or not at all. Consequently, the furnace will always run in order to maintain a desired level of comfort within your home.
Two-stage furnace, in comparison, have two stages of operation, low and high. While in the low stage, the furnace runs at reduced capacity in order to maintain a desired temperature more efficiently within your home. When additional warmth or cooling is desired, the furnace will shift to its high stage and operate at peak capacity.
