Boiler vs. Furnace: What’s the Difference and Which is Better?

As a homeowner, you should ensure that your house is well-heated and choose the best heating system for your home. The most popular types of home heating systems are boilers and furnaces. Whichever you choose, ensure it is well-maintained and cared for by professional HVAC personnel near you. 

However, some homeowners might be confused about which type of heating system to use. Whether planning a home remodeling project or moving into a new home, you might have to look into each heating system, what makes them different from each other, and determine which option is the best choice for you. 

Boilers vs. Furnaces: What are the differences?

Most homes use either boilers or furnaces to heat their homes. On the one hand, boilers heat water and provide steam for heating or hot water. The steam is then distributed through pipes to steam radiators. 

Steam boilers also tend to operate at a higher temperature than hot water boilers. Meanwhile, a coil can distribute hot water through baseboard radiators or heat air. On the other hand, furnaces work by heating air and circulating throughout the house via ducts. 

A boiler or furnace’s efficiency is measured using annual fuel utilization efficiency (AFUE). The Federal Trade Commission requires boiler and furnace manufacturers to display the AFUE so that consumers can determine the appliance’s efficiency in fuel to heat conversion. 


In Spring Hill, TN, homeowners can benefit greatly from investing in boilers and furnaces. For perspective, a natural gas furnace typically has a lifespan of 15 to 20 years. On the other hand, with appropriate care and maintenance, boilers can serve effectively for 10 to 15 years.

Energy efficiency 

Using a boiler or furnace could take up a huge chunk of your energy bill. So if you are looking for ways to improve your home’s energy efficiency, you should check your home heating system. So, which is more energy-efficient, a boiler or furnace? The answer is neither. It depends on the boiler or furnace you have for your home heating needs. 

Fuel consumption 

A residential boiler uses natural gas or oil to power the appliance. The same applies to furnaces that also use natural gas, but some also use oil or electricity. Natural gas is said to be the most energy-efficient. 

Which one should you choose, a boiler or a furnace? It all depends on your home’s heating needs. Both boiler and furnace have their pros and cons. Every home has different heating needs. 

Of course, it is your responsibility to ensure that your home is well-heated and your home heating system well-functioning. That is why it is important to work with skilled HVAC personnel in Spring Hill, TN, to help you find the best heating system for your home.
