Furnace vs Boiler

There are so many types of heating systems that sometimes the terms can get confusing. It’s good to know what type of system you have so that the proper maintenance can be provided. It is also important if a heating emergency occurs. If you are looking to install a new system, this may also be helpful to you in choosing the option that’s right for you.

Furnace

These types of units heat air, which is then blown through a ducting network within the structure. These units can usually be identified by rectangular, silver, ducts that feed off the unit and into the building. If you have found yourself gravitating towards a warm stream of air coming out of a vent in the ceiling or floor grate, you most likely have a furnace.

These units typically have an air filter that should be switched out on a regular basis. Monthly or quarterly should be good enough, but if you have pets, you may have to change them more often. These units can be further enhanced with the addition of air purification ionization systems which can remove pollen, dander, viruses, bacteria, and mold particles.

These units are also usually paired with an electric hot water heater, or an on-demand boiler to supply hot water.

Pros: Less noisy, comfortable heat, better air quality, heated water can be recycled.

Cons: Can create dry drafty environments, can aggravate allergies, requires regular maintenance.

Boilers

These units heat water instead of air. The is heated water by passing through the unit using coiled metal tubes. The water will then exit the boiler and feed directly into the house’s hot water plumbing. Hot water will go directly to faucets. Water used for heating will pass through baseboards, or be used in radiant floor heating systems. If the sounds of ticking baseboard heaters in winter brings you comfort, then you have a boiler.

These can usually be stand alone units, or can be paired with a hot water tank to store up hot water in an energy efficient manner and keep up with daily demand. Depending on the type of setup, they can be floor mounted, or wall mounted.

Pros: Costs less and takes less time to install, has less chance of freezing

Cons: More expensive to install, damage from leaks or burst pipes can be expensive.
