Furnaces vs. Boilers

Other Solutions

Our Malvern heating and cooling company posted this blog a couple years ago, but since the weather is getting cooler and you may be thinking about replacing your heating unit, we thought it would be a good time to repost:

There are some major distinctions between furnaces and boilers, and both have advantages and disadvantages when it comes to heating your home. Before you decide which you’d prefer, learn more about what makes them different:

Thermostat Control

A furnace acts like a central heating system for your home. It transports hot air throughout your home’s duct work and vents to heat all of the rooms at the same time. A boiler, however, works in conjunction with several heaters throughout your home. This means that you can adjust the thermostat of each room a heater is in.

Operation

A furnace uses gas, oil, or electricity to heat a series of coils, then uses a blower to move air across the heated coil and distributes it throughout your home via duct work and vents. Boilers, however, use water as a source of heat. After water is heated in the boiler, it is distributed to various heaters or radiators throughout your home. While a boiler is much quieter than a furnace, it takes longer to heat up.

Maintenance

Because a furnace uses air (instead of water) to push heat throughout your home, dust will collect in the filters and you’ll need to clean or change them every few months. When it comes to leaks, if you experience a leak in your boiler, it can pose a property damage threat to your walls, ceilings, or floors. A leak in your furnace, however, is easy to fix.

Efficiency

The efficiency of any heating system depends on what you buy, but today’s boilers and furnaces are both created with 80% – 95% efficiency. When it comes to heat loss, however, furnaces usually lose more because the duct work and vents tend to absorb it as it passes through.

Cost

Many homeowners choose to heat their homes with furnaces because they cost less. Mid-efficiency boilers cost between $2,500 and $4,000, while mid-efficiency furnaces cost between $2,000 and $3,000. Both high-efficiency boilers and furnaces can cost over $5,000, but some boilers can reach a cost of $10,000.

Air Quality

If you’re looking for better air quality for you and your family, it’s wiser to invest in a boiler. A furnaces heats your home with warm air, which also circulates dust, allergens, and other airborne particles throughout each room and decrease your air quality.
