Ultimate Guide to Different Types of Furnaces

different types of furnacesWhen winter sets in, few things matter more than reliable home heating. For many people, a furnace is the best choice. It is powerful, long-lasting, and can fit in many spaces, like basements and attics.

The choice of the right furnace isn’t just about heating; it impacts energy bills, home comfort, and even how much time you spend tinkering with the thermostat. With a variety of  different fuels and types available, choosing the best furnace might seem like sorting through a crowd at a concert, all yelling for your attention. So, let’s break down the main types of furnaces to help you make a smart choice.

Key Takeaways

  • Understand the main furnace types: natural gas, oil, electric, and propane.
  • Learn what each type of furnace offers in terms of efficiency and cost.
  • Know the key factors—like size of your home, climate, and efficiency ratings—that can affect your choice.
  • Explore the pros and cons of new technologies, like solar-powered furnaces.

What Is a Furnace?

A furnace is the workhorse of a home’s heating system, warming and distributing air through ductwork. It’s often called a “forced-air” system because it pushes warm air through the home via a blower.

Furnaces rely on fuel types like natural gas, oil, propane, or electricity, each with its own heating process. Natural gas requires a heat exchanger, electric models use heating elements, and oil or propane varieties have their unique methods.

While there are plenty of non-furnace options (think heat pumps or boilers), today, we’re focusing on furnaces and how they keep homes cozy.

Different Types of Furnaces

There are four primary types of furnaces, each with its own advantages, quirks, and ideal conditions. Let’s look at what sets each one apart.

Natural Gas Furnace

In 2020, over 61% of American households kept warm with natural gas, and there’s a good reason for that. These furnaces connect to a municipal gas line, making them convenient and relatively affordable.

Inside, natural gas burns in a heat exchanger, warming up the air before it’s pumped through your home. People love gas furnaces because they’re efficient and usually offer lower monthly heating costs.

Oil Furnace

Only about 4.4% of households in the U.S. use oil, with most of those homes in colder, rural areas in the Northeastern United States.

Oil furnaces work by burning oil to heat air, which is then distributed. They’re typically less efficient than gas powered models, but they provide a good option where gas service is unavailable.

Electric Furnace

Electric furnaces work differently. Instead of burning fuel, they use heated elements to warm air, making them a good fit for regions where electricity is the main energy source. The upfront cost is lower, and installation is generally easier.

However, they tend to be less efficient in terms of monthly bills, so if you live in a cold region, you might want to think twice.

Propane Furnace

Propane furnaces cater to more rural areas, where you might not have access to gas or oil lines. Propane is stored in tanks, offering flexibility, but only about 4.9% of U.S. households use propane heating. Still, for people in isolated areas, a propane furnace can be a convenient, reliable option.

Key Considerations When Choosing a Furnace

gas furnace repair Picking a furnace isn’t as simple as grabbing the first model you see. Here are some things to weigh when making your choice.

Size

Too big, and you’ll waste energy (and money). Too small, and it won’t heat effectively.

Furnace sizes are measured in BTUs (British Thermal Units), which indicate how much heat they produce. For instance, a home around 1,200 square feet needs about 36,000-72,000 BTUs. Choosing the right size helps your furnace run efficiently without breaking a sweat.

Climate and Region

Where you live impacts what furnace is best. Colder areas, especially with gas lines, lean towards natural gas or oil. In milder or more isolated areas, electric or propane models might make more sense.

AFUE Rating

AFUE, or Annual Fuel Utilization Efficiency, measures a furnace’s efficiency. Higher ratings mean more energy saved—ideal if you’re looking to cut down those bills.

However, to really benefit, your home needs solid insulation. A high-efficiency furnace in a poorly insulated home is like trying to fill a leaky bucket.

Compare Furnace Reviews

Shopping for a furnace without reviews is like buying a car without a test drive. Look at customer feedback and consult sources like Consumer Reports or the Better Business Bureau.

These reviews provide insights on reliability, satisfaction, and contractor performance helping you avoid potential headaches down the line.

What About Solar-Powered Furnaces?

Solar furnaces are the new kid on the block, using concentrated solar energy to heat homes. They reduce reliance on fossil fuels and work well in sunny regions, especially in arid climates.

However, they’re a bigger investment upfront and need plenty of direct sunlight to work optimally. Solar heating might not be for everyone, but it’s worth considering if energy bills and sustainability are your priorities.

FAQs About Different Types of Furnaces

Here are answers to some common questions about furnaces and their operation. Whether you’re curious about fuel types or maintenance tips, these FAQs might answer what’s on your mind.

What furnace type is the cheapest to run?

Natural gas is usually the most affordable in the long run, especially if you have access to municipal gas lines.

Can I replace an oil furnace with a gas furnace?

Yes, but it depends on having a gas line available. Conversion costs can vary based on existing systems and installation complexity.

Is an electric furnace a good choice for a cold climate?

While electric furnaces are efficient, they can be expensive to run in very cold areas. They’re often better suited for milder climates.

How often should I get my furnace serviced?

Annual maintenance is generally recommended for all types to keep them running efficiently and to spot any potential issues early.
