The difference between a furnace and a boiler
Something I have learned in talking to people is that for most folks, all heating systems are considered “furnaces.” So what’s the difference and why does this matter? “Furnace, boiler, it’s all the same thing.” People think it is just semantics, but it’s not. Sure, we get the idea, and we understand that you are talking about your heating system. But they are not the same thing. A boiler uses hot water to heat your living space, while a furnace uses warm air. The heat is different, and the way that heat is circulated through your home is different.
I was recently talking to a customer on the phone about installing central air conditioning in her home. Of course, over the phone, you must ask “qualifying questions.” Now, I work in the heating and cooling industry, so I have learned the “lingo.” However, if you don’t understand the terminology, it is difficult, really, to answer the questions. This woman was insisting that she had duct work and a furnace in her home. I learned however, that she had a boiler with baseboards.
Ductwork, Warm Air, Hot Water, Boiler, Furnace. Some people just really do not see the difference.
Now when speaking with customers, I learned a long, long time ago that the customer is always right. So when they are insisting they have something that they don’t, it is sometimes difficult to convince them otherwise. Maybe you finally ask the question that helps them understand what type of equipment they have. Most people know what baseboards are, and if you have them, you have a boiler, not a furnace, and chances are you do not have duct work.
We have a diagram on our website that shows the different types of equipment.
Hydronic = Boiler = Hot Water
Warm Air = Furnace = Warm Air
Of course, like everything else in the world, there are exceptions:
Hyro-Air = Boiler + Air Handler = Warm Air
With hydro-air we introduce the addition of the air handler that turns the hot water into warm air. These systems are typically more efficient, and are engineered to create a less dry heat, efficient hot water heating, and air conditioning all in one.
