Boiler Vs Furnace – Which Is More Efficient In 2022

Even though they both serve the same objective (heating your house), boilers and furnaces operate in separate ways. Boilers heat water and convert it to steam or hot water before distributing it around your house, whereas furnaces heat air and transport it via your duct system with the help of a blower. Aside from this significant difference, there are several additional differences between boilers and furnaces, such as pricing, installation, and servicing. We’ll go through how both types of heaters perform in each of these categories and more in this tutorial. We’ll also give you a quick rundown of the key similarities and differences to assist you in deciding which heating system is best for you.


Boiler’s heat water and convert it to steam or hot water, which is then pumped through pipes and distributed through radiators throughout your home. Radiators come in a variety of shapes and sizes, including baseboard radiators, cast iron radiators, and radiant floor heating systems (which include a set of pipes beneath the floorboards that emanate heat and warm your floors). Modern boilers are often powered by natural gas or oil, although some types may run on electricity or wood pellets.


Furnaces, on the other hand, take in cold air, warm it up, and then spread it throughout your home via ductwork. The air is then released through vents to heat different parts of your home. Natural gas, propane, oil, or electricity are the most common fuels for furnaces. A conventional furnace has numerous distinct components, including a burner (for burning fuel), heat exchangers (for transferring heat), a blower fan (for distributing heat), and a flue (for exhaust).


Furnaces are the more affordable choice, with a new midrange furnace costing anywhere from $1,500 to $6,000. Boilers are more expensive, with an average model costing between $3,600 and $8,200. Keep in mind that this pricing only covers the appliances themselves and does not include installation or fuel.


 New Boilers installation is more difficult than furnaces. Most furnaces can be placed in a matter of hours, but other boilers might take days. Furnace installation costs roughly $2,000 on average, whereas boiler installation costs more owing to the additional time necessary.

In any case, both sorts of installation might be difficult. Depending on the type of furnace or boiler you pick, attaching a new model may need dealing with a natural gas line, electric hook-ups, or other fuel sources – all of which are dangerous and should be handled by a professional.


When it comes to boiler and furnace maintenance, boilers come out on top. When compared to furnaces, they don’t require much regular care. Regardless, you should get your boiler examined by an HVAC specialist once a year.

If you have a furnace, though, it’s critical to keep it in good condition. An HVAC specialist will calibrate the burners, clean the combustion chamber, clean the fan, and more during a furnace cleaning and inspection once a year. You should also replace your furnace filters every few months or so, in addition to the yearly cleaning.

Efficiency and effectiveness

Heating your home with water (as in a boiler) uses less energy than heating your home with air (as in a furnace), therefore boilers will burn through fuel more slowly than furnaces. In other words, a boiler may have cheaper energy and running expenses than a furnace.

The annual fuel utilization efficiency (AFUE) of a boiler or furnace is a measure of how much energy the heating system creates versus how much fuel it uses.

The most efficient boilers and furnaces now have AFUE ratings of 90 to 98.5 per cent. In other words, the greater the AFUE rating, the less gasoline is wasted, saving you money and not harmful to the environment.

Life expectancy

In terms of projected longevity, furnaces and boilers are comparable, although furnaces have a little advantage. Furnaces may endure anywhere from 15 to 30 years if properly maintained. Boilers may endure up to 20 years on average. Of course, how often you use it and how well it’s maintained will determine how long it lasts.
