When it comes to heating your home, there are a lot of different options. A variety of HVAC equipment tends to get lumped together into the heater category, but the reality is that they use a variety of techniques to generate warmth. These differences can also have a major impact on your utility bills, air quality, and comfort, so it’s worth learning about them. Keep reading to find out how furnaces and boilers work and see which one is right for you.
What Is a Furnace?
A furnace is a heater that works by warming up air and then blowing the warm air throughout your home. There are several ways to fuel a furnace, including gas and electricity. Whatever power the furnace runs on, it generates heat directly and lets the air absorb that heat. The furnace then uses blower fans to spread the air throughout the ducts and into your home. When your furnace is running, it’s constantly circulating air. The fans will pull cool air into the furnace via a return duct and then blow heated air into your home from supply vents. Furnaces are one of the most popular types of heaters available. They work with most standard HVAC designs, so you can find them in all sorts of homes.
What Is a Boiler?
A boiler is a heater that works by distributing water. Boilers use fuel to heat up a tank of water. This hot water is then distributed throughout your home through a series of pipes. Depending on how your boiler is set up, it might use a radiant floor system, radiators, or heated baseboards. Some boilers may also distribute steam instead of liquid water. Wherever the hot water goes in your home, it gradually releases heat into the air and warms up the temperature of your house. Some boilers may also heat water for other purposes, such as showers or washing dishes. Boilers are a less common type of technology. They were more common in historic homes, but they’re gradually becoming popular again in modern times.
Which One Is Right for You?
Whether your heater warms air or water might seem like a minor distinction, but it can greatly change how your home feels. If you’re trying to decide between the two styles of heater, here are some important factors to consider.
Efficiency
If you’re looking for ways to heat your home without using a lot of fuel, a boiler is a better pick. In general, water transfers temperatures more efficiently than air does. This means that it takes more energy to heat air than it does to heat water. The exact amount of money it costs to run a furnace or a boiler will depend on things like your local fuel rates, the efficiency of the model you select, and the type of fuel you use. However, the overall cost to run a boiler can be as low as half the cost to run a furnace.
Comfort and Convenience
While it’s largely a matter of personal preference, many homeowners report that boilers are more comfortable. This is partially due to humidity levels. Furnaces remove moisture from the air as they run, so when you end up with a heater running nonstop in winter, air can become uncomfortably dry. Boilers have more stable levels of humidity, so you don’t get uneven swings in moisture levels. With boilers, you’re less likely to have static shocks, dry skin, and other issues. The ambient heat provided by boilers tends to be even and gentle no matter how long it runs. Another advantage of boilers is that they’re much quieter. You might hear the occasional gurgle of the water tank warming up or refilling. However, you won’t hear the rushing noises of a furnace moving air around. Despite these issues, furnaces may have a slight advantage when it comes to convenience. Many homeowners find that the ducts and vents of furnaces have a lower profile. Unlike a radiator, the components of a furnace do not take up wall space or require you to decorate around them.
Air Quality
When it comes to air quality, both types of heaters have their pros and cons. Overall, boilers tend to be better. Since they aren’t blowing air around, they don’t kick up a lot of dust and allergens. This ensures that things like mold spores aren’t circulating through your home. However, it also means that boilers don’t help with circulation. Furnaces move air throughout your home, so they can filter air and improve ventilation. If your HVAC system is set up with effective filters and ventilation options, it can spread fresh air through your home in a way that a boiler can’t. Ultimately, the average boiler will be better for air quality than the average furnace, but if your home’s HVAC system is set up with air quality in mind, a customized furnace and ventilation system can be better.
Price
Since furnaces are more common, there are a lot more options. This lets you shop around and find much lower prices for equipment. Furnaces are also less complex than boilers and use fewer parts, and this contributes to their lower purchase price. When it comes to installation, furnaces also win out. Most furnace installations are straightforward and use the ductwork system you already have in place for your air conditioner. Meanwhile, boilers can require additional installation for things like radiators or flooring, so adding the entire boiler system to your home is a big project. Don’t forget about the better efficiency of boilers though. Even if the initial cost is higher, you often save money in the long run with a boiler system.
Maintenance and Repairs
Neither furnaces nor boilers require a lot of maintenance beyond an annual service visit. However, furnaces will need you to change their filters every month or two, so there can be a few extra minutes of maintenance. If something goes wrong with your system, furnaces can be preferable. A broken furnace usually just means a cold house, strange noises, or some unpleasant smells. Unfortunately, a broken boiler can be a large hassle. If something goes wrong, a boiler can leak, and the hot water inside it can cause a lot of damage to your home.
