High Efficiency Boiler System

Boiler vs. Furnace: What is the difference?

Boiler vs Furnace. It is crucial to choose the correct heating method for your home. The process involves many factors, such as energy efficiency, size, climate, repair costs, and more. To determine which system is best for your home, take the time to understand how each system functions.

What is the difference between a Boiler and a Furnace? 

Boiler heat is different from furnace heating. A boiler heats your home with hot water, steam or hot water while a furnace heats it with warm air. The contrast goes beyond that. Each system works differently to provide climate control in sub-zero temperatures. It is essential to consider other factors such as repair costs and initial installation when deciding which one is right for you.

How do they work?

The operation of each type is another vital aspect to remember when deciding between boiler and heater. Natural gas, propane, and electricity are the three primary fuels for furnace systems. The furnace heats air and pushes it through your home’s ductwork with a blower. However, the air can sometimes feel less comfortable because of dryness.


Natural gas, oil and electricity are the primary energy sources for boiler systems. Boilers heat water to scorching temperatures, and use a pump to heat radiant floors, cast iron radiators, and baseboard radiators throughout your house. Radiantly heated air is the best option for your home because it doesn’t require a blower.


In summer, you can combine furnaces or boilers with air conditioning systems to cool your home. However, some homes may require additional ductwork to make this possible.

Maintenance requirements

A boiler system has different maintenance requirements than a furnace. A professional can perform an annual tune-up on boiler units. In contrast, furnaces require a yearly inspection and the maintenance of your air filters every other month or quarterly. You will need to change your furnace filters more frequently if you live in an area with high dust or pets. 


There are some maintenance differences between a natural gas furnace and a natural gas boiler. It is vital to have both systems checked by a professional service provider once a year to reduce the chance of natural gas poisoning and natural gas leaks.

Pros vs. cons

There are many differences between a boiler and a heater. Furnaces are often cheaper and require less time to set up than boiler systems. Furnaces don’t use water to heat the house, so there is less chance of freezing during a power cut. However, ductwork can lead to a drafty environment. Leaky ducts are especially dangerous for people with allergies. Natural gas furnaces can also be susceptible to valve leakage, leading to serious health problems.


Radiant heat from a boiler system, on the other hand, is more comfortable than forced furnace air. These units also produce better indoor air quality and are quieter, more efficient, and less noisy. There is no need for ductwork. You can reuse the heated water in certain situations for laundry, showers or dishwashers. These systems can be costly to install and could cause significant damage to your home if they leak.


It is essential to research the different heating systems available and compare them with your specific needs before you decide which one you want. A boiler system is the best choice in most cases. However, there are pros and cons to both types of heating systems.

Boiler vs Furnace – What’s the Difference?

It is vital to choose the right heating system. It’s crucial to understand how each system works to determine what heating system is best for you. This guide will help you with your fact-finding mission.

What is the difference?

A boiler uses hot water (or steam) from hot water to heat your home. A furnace circulates warm air through ductwork.

Energy Source?

The energy source for boilers is natural gas or oil, electricity, and wood pellets. Natural gas, propane, and electricity are all options for heating a furnace.

How do they work?

Boiler systems heat water to scorching temperatures. They use a special pump that heats radiant flooring systems, cast-iron radiators, and baseboard radiators in your house.

A furnace heats the air and pushes it through ductwork with a blower to create a high ambient temperature.

Maintenance requirements

Boilers need very little maintenance other than an annual check-up by a professional.

Furnaces need an annual inspection and filter changes every two months.

Pros & Cons: Boiler vs Furnace

It is essential to research the pros and cons of each heating system to choose the best one for you. A boiler is the best option in most cases. However, there are pros and cons to every type of heating system.

Boiler Pros

  • Heat is more comfortable
  • Less noisy
  • More energy efficiency
  • No ductwork is required
  • Better air quality
  • Reusable heater water

Boiler Cons

  • Higher prices
  • Leakage can cause extensive damage

Furnace Pros

  • Cost less
  • Installs in less time
  • There is less chance of freezing during winter

Furnace Cons

  • Drafty environment
  • Families with allergies are at greater risk
  • Avoid valve leakage

It is crucial to have your natural gas and carbon monoxide systems checked annually by an expert to reduce the chance of poisoning yourself or leaking natural gas.
