What are the differences between a boiler and a furnace?

Many people may not realize there are big differences between a boiler and a furnace. They are similar in that they both provide heat, but different in how the heat is distributed, the energy sources used, the energy efficiency offered and the cost to operate and replace.

Boilers

Function: A boiler heats and circulates hot water or steam through pipes in the house, and then distributes the heat throughout the house via a radiator, radiant floor system or through a coil.

Energy Source: Boilers can be powered by natural gas, oil, electricity and wood.

Energy Efficiency: Boilers require less fuel to heat your home compared to a furnace, but depending on the energy source, the efficiency can range from 80-90%. Since there is no ductwork in this system, energy is not lost through the distribution of the heat.

Cost: Typically, boilers are more expensive than a furnace due their increased complexity during installation. You can expect to pay $2,500-$4,000 for a mid-range model or $5,000-$10,000 for a high-efficiency model – both prices include installation. However, the annual average cost of operating a boiler is significantly lower than operating a furnace. The operating cost of a boiler can vary between $250-$700 depending on the energy source of the boiler and how much the unit is being used throughout the year.

Pros:

  • More Energy Efficient – Boilers use less fuel to operate, which means your energy costs during operation will be lower.
  • More Consistent Heating – A boiler produces more consistent heating through the heating of water rather than the forced air heat.
  • Less Noise During Operation – Boilers are usually quieter since they don’t have to blow air throughout the house.
  • Requires Less Maintenance Over its Lifetime – Boilers do not require an annual filter change or cleaning, but general maintenance of the unit annually is highly recommended to prevent more expensive repairs in the future.
  • Better Air Quality – Boilers do not use ductwork to push the warm air throughout the home, so they don’t spread dust or allergens, and they generally provide a moister air than a furnace.
  • Higher Resale Value for Your Home – Heating units are known for lasting 15-30 years, but boilers tend to last even longer, especially newer models that are more energy efficient.
  • Best for Cold & Northern Climates – Due to its ability to provide more consistent heating, it is most recommended for regions with longer and colder winters, such as in Denver and across Colorado.

Cons:

  • Slower to Adapt to Changing Temperatures – If you turn the heat up or down, expect the unit to take longer to adjust to the temperature changes.
  • More Difficult to Install – Usually requires the installation by a professional.
  • Harder to Convert – If you choose a boiler now but want to a convert to a furnace later, it’s more difficult to convert since the furnace requires the installation of ductwork throughout the home.
  • Potential Water Damage – If the boiler leaks or freezes, you could incur water damage or damage to the pipes or equipment used by the boiler.

Furnaces

Function: A furnace heats the air and forces the hot air throughout your home using a blower motor and a series of air ducts and vents.

Energy Source: Furnaces are powered by electricity, natural gas, propane or oil.

Energy Efficiency: Depending on the model of the furnace or the energy source being used, the efficiency can range from 55-98%. However, efficiency is most lost in the ductwork of the heating system, up to 35%.

Cost: Depending on the model and energy source of the furnace, you can expect to pay between $650-$2,000 for a new furnace. However, the operating cost of running the furnace is generally much higher than a boiler, usually between $800-$1600 annually.

Pros:

  • More Affordable Unit & Installation – The unit itself is cheaper as is the professional installation of the unit.
  • Best for Southern Climates – Due to the higher annual average temperature in the southern states, furnaces are often paired with A/C units, which are a necessity in the summer.
  • No Leak or Freeze Hazards – The unit does not run on water, so the potential of damage is minimal.

Cons:

  • Less Efficient – The furnace will use more of its energy source to operate, so the operational cost is much higher for a furnace compared to a boiler.
  • Noisier Operation – Due to its function, the furnace will make noise every time it starts up and begins to blow air.
  • Poor Air Quality – The ductwork of the furnace can hold dust and allergens, and the heated air is usually drier.
  • Inconsistent Heating – Some rooms may be hotter or cooler than others since forced air heat is not as consistent as steam or hot water heat.

Depending on your unique situation, you may prefer one unit over the other. However, Rabbit Heating of Denver highly recommends a boiler unit to heat homes in Colorado due to their longer, harsher winters and the benefits that a boiler unit can provide to your home.
