Two-stage furnaces are becoming increasingly popular for home heating solutions due to their energy efficiency, flexibility, and cost savings. These systems use two different levels of heat output to reduce the amount of energy consumed while still providing reliable home comfort.
By cycling between a high and low stage, two-stage furnaces can provide consistent temperature control with a more even heat distribution throughout your home. With features like variable speed blowers and programmable thermostats, two-stage furnaces offer an efficient heating solution for any size home.
In this blog post, we will explore what two stage furnaces are, how they work, and the benefits of using them in your home. If you want to install a new furnace in your home, click here.
What are two stage gas furnaces?
A two stage furnace is a type of heating system that has two sets of burners, which operate in two stages, rather than one. Unlike traditional single-stage furnaces, where the furnace operates at full capacity all the time, these furnaces can adjust the heat output according to the temperature requirements.
Two-stage furnaces are typically gas-powered, using natural gas or propane. Some newer models may use electric heating elements but most two-stage furnaces are powered by gas. Natural gas is the most popular choice of fuel for two-stage furnaces due to its lower cost and availability across many parts of the country.
How do they work?
Two stage furnaces have two separate heat settings: high heat and low heat. In the first stage, when the furnace is turned on, it runs on low heat, consuming less energy and fuel. This low heat setting is ideal for mild winter days, where only a small amount of heat is needed to keep the home comfortable.
In the second stage, when the temperature drops and more heat is required, the furnace kicks into high gear and can produce more heat. This dual-stage operation helps ensure that the furnace only uses as much energy as it needs, thereby saving on utility costs.
The operation of two stage furnaces is controlled by an advanced electronic controller, which monitors the outside temperature and adjusts the furnace operation accordingly.
How two-stage furnaces differ from other types of furnaces
Two-stage furnaces differ from other types of furnaces in several ways. First, they use two distinct levels of heat output to maintain an even temperature throughout your home. This is connected to the ability to cycle between a high and low setting which further helps to reduce energy consumption.
Two-stage furnaces also come with variable speed blowers, so they can adjust the airflow according to their needs while still providing comfortable temperatures. Additionally, two-stage furnaces are often equipped with programmable thermostats that offer more precise control over when and how long the furnace runs for greater energy efficiency and cost savings.
Programmable thermostats
Programmable thermostats are essential for two-stage furnaces because they allow you to control and customize the temperature settings according to your climate.
With a programmable thermostat, you can choose to run the furnace in its high setting when temperatures drop below a certain point, or you can set it to run at a lower setting during milder weather. This allows for more efficient use of energy and cost savings in the long run.
Additionally, programmable thermostats can be programmed with different schedules throughout the day and night, allowing for greater control over when and how often the furnace runs.
Benefits of using two stage furnaces:
Using a two-stage furnace has numerous advantages. Some of these include:
Energy efficiency
The primary advantage of these furnaces is their energy efficiency. By operating on low heat most of the time, two stage furnaces consume less energy, and in turn, reduce your home’s energy bills.
Cost-effective
Since they consume less energy, this translates to reduced utility bills in the long run. While they may be slightly more expensive up front, they pay for themselves in the long run with energy savings.
Comfortable heating
A two stage furnace is designed to provide a more uniform and comfortable heating experience compared to traditional furnaces. By providing two separate heat settings, the furnace can operate more comfortably in a range of outdoor temperatures.
Better air quality
Air filters have a longer lifespan because the system is not running at full capacity all the time. This enhances overall air quality, as it prevents the build up of dirt and dust in filters and therefore stops it from circulating throughout the house.
Improved lifespan
Because they operate at a lower capacity for longer periods, there is less wear and tear on the system, which can contribute to an extended lifespan.
Reduced sound
Two stage furnaces are typically quieter than single-stage furnaces, making them ideal for homeowners who want to enjoy comfortable heating without any noise disturbance.
Choosing the right two stage furnace
When choosing a two stage furnace, it is essential to work with an HVAC professional who can help you determine the right furnace size and specifications for your home’s heating needs. Factors to consider when choosing a furnace include your home’s square footage, insulation levels, and climate conditions.
In addition to the type of furnace required, HVAC professionals can also help with installing and maintaining the furnace to ensure it is functioning efficiently and effectively.
Conclusion
These types of furnaces are an excellent option for homeowners looking for a comfortable, energy-efficient heating system that can provide consistent heat in a range of outdoor temperatures. With the right furnace and proper installation and maintenance, homeowners can enjoy lower energy bills and a more comfortable home environment for years to come.
