How Does a Residential Boiler Actually Work?
In the U.S., roughly 9 million homes have boiler heating systems. More than half of the homes with boilers are in the Northeast.
Even though boilers are rare in American homes, those who do have them become major fans. Boilers offer radiant heat that can't be beat in cold climates.
But, how does a boiler heat a home?
The good news is, it's not as complicated as you might think. Read on to learn what a residential boiler is and how it works.
Boiler vs Furnace: What's the Difference?
A boiler and a furnace are both types of central heating systems, but boilers use water and furnaces use air.
Boilers use hot water or steam to warm your house. The water or steam travels through pipes or radiators and warms the objects in your home.
Furnaces blow hot air through a duct system, which warms the air in your home.
How Does a Boiler Work?
A fuel source such as natural gas enters your home and travels to the boiler. The gas comes out through small jets where it's ignited and turned into a heat source. The heat from the ignited gas goes through the heat exchanger, which warms a water pipe or tank of water.
If you have a hot water boiler, the hot water will travel through the pipes in your floor radiators with the help of a motorized pump. Once the water has heated the room, it travels back to the boiler to get reheated.
If you have a steam boiler, the heat exchanger will continue heating the water until it turns to steam. The steam will rise to the radiators in your home. Once it's heated the room, the steam turns back into water and returns to the boiler to start the process again.
If you can't visualize the cycle, a how a boiler works diagram might help.
The burning fuel produces combustion gases which the venting system takes out of your home. Without this vent, you'd have a buildup of dangerous carbon monoxide gas.
Types of Residential Boilers
While the application of boilers in your home is always the same—they all provide central heat—there are three types of boilers.
Gas fired boilers use natural gas or propane, but are not an option if you don't have access to natural gas. Oil fired boilers require a regular supply of oil which you'll need delivered to your home. Electric boilers are very efficient, but are expensive given the high cost of electricity.
There are also three types of radiators, which bring heat into each room. Steam radiators are larger metal units you might've noticed in older homes.
Hot water radiators are small and sit along the baseboard of each room. Hydronic radiant floor heating uses a network of coils to warm the floor of each room.

I really appreciated Manolos attitude and the way he had patience for all of my questions and never seemed like he was rushing or annoyed with me. He took the time to reexplain it to my husband when he got home. I didn't feel pressured into spending more money or like he was trying to just sell me stuff. I felt like he really took his time and that I was his priority. Thank you for having great service.
z was fantastic! Very nice and easy to talk to and he explained everything perfect! Very professional! I would recommend him to anyone !
This was my first time with 1-800-Plumber Air of Pearland. I called with a minor issue with the dishwasher drain hose and asked that a tech be dispatched on Saturday so that I could be home from work. Chad was scheduled between 8am & 10am today (Sat) and arrived just before 9am. Chad was very knowledgeable and explained to me the entire process. He also answered my many many questions about what he was doing as he was doing it. I'm a smart guy but know very little about plumbing. I felt very comfortable with Chad doing the repair. The long and the short of it, 1-800-Plumber Air of Pearland has a new longtime customer and I will request that Chad be sent if possible the next time I have a plumbing issue.
Kyle Urban is great! He does beautiful work and is a great guy! We will request him personally from now on.
Got a text! Dispatcher was friendly and informative. Several text keeping me up to date and giving me plenty of opportunity to cancel if need be. Z was prompt, curtious and knowledgeable. Was glad to sign up for future business with the company. Excellent experience.
