Furnace vs. Heat Pump: Which One Is Right for Your Home?

When it comes to heating your home, there are various options available, each with its unique set of advantages. Two of the most popular heating systems are furnaces and heat pumps. Both have been designed to efficiently heat your home, but they operate on different principles and are suited for different needs. So, how do you know which one is right for your home?

In this blog, we'll compare furnaces and heat pumps, covering how each system works, their advantages and disadvantages, and factors you should consider before making your decision. By the end of this guide, you'll have a clearer idea of which heating system best fits your home’s needs. At Aqua Plumbing & Heating, we have been serving Edmonton residents with heating and plumbing services since 1985. Whether you need a furnace installation or a heat pump, our professional team can guide you through the best options for your home.

How Does a Furnace Work?

A furnace is a traditional heating system that generates heat by burning fuel (natural gas, oil, or propane) or using electricity. The heat produced is then distributed throughout the home via a system of ducts and vents. A furnace typically consists of the following components:

• Burner: In a gas or oil furnace, this is where the fuel is burned to generate heat.
• Heat Exchanger: This component transfers the heat produced by the burner into the air circulating through the ducts.
• Blower: The blower fan pushes warm air through the ducts to heat the rooms in the home.

Furnaces are generally known for their ability to heat homes quickly and efficiently, especially in colder climates like Edmonton. They are often favored in areas with extreme winters because they can consistently provide a high level of warmth, even in sub-zero temperatures.

How Does a Heat Pump Work?

A heat pump works differently than a furnace. It doesn't generate heat by burning fuel; instead, it moves heat from one place to another. Heat pumps use electricity to transfer heat from the outside air or ground into your home. In the winter, the heat pump extracts heat from the outdoor air (even when temperatures are below freezing) and brings it inside. In the summer, the process can be reversed, with the heat pump pulling heat from the indoor air and expelling it outside, acting as an air conditioner.

Heat pumps consist of the following key components:

• Evaporator Coil: This is where heat is absorbed from the outdoor air or ground.
• Compressor: The compressor moves the refrigerant through the system, helping to transfer heat to the indoor unit.
• Condenser Coil: This releases heat into your home during the heating process or removes it in cooling mode.

Heat pumps are considered highly energy-efficient systems because they use electricity to move heat rather than generating it from a fuel source. They can be an ideal choice for homeowners in regions with moderate winters, though they can also handle extremely cold temperatures when equipped with an auxiliary heat source.

Furnace vs. Heat Pump: Efficiency Comparison

One of the most important factors when choosing a heating system is energy efficiency. The higher the efficiency of your system, the lower your utility bills will be over time.

Furnace Efficiency

Furnaces are generally very efficient when it comes to providing heat quickly. Natural gas furnaces, in particular, have high Annual Fuel Utilization Efficiency (AFUE) ratings, often in the range of 90-98%. This means that nearly all of the energy from the fuel is used to produce heat. However, the efficiency of a furnace depends on factors like the type of fuel used, the quality of the unit, and how well the system is maintained.

Gas furnaces typically perform best in colder climates, where they are capable of providing a high output of heat regardless of the outdoor temperature. However, while they are efficient at heating, they still require the burning of fossil fuels, which has an environmental impact.

Heat Pump Efficiency

Heat pumps are known for their high energy efficiency, particularly in moderate climates. Because they transfer heat rather than generating it, they can be 3-4 times more efficient than traditional furnaces. A heat pump's efficiency is measured by its Heating Seasonal Performance Factor (HSPF), which indicates the amount of heating provided per unit of electricity consumed. In ideal conditions, heat pumps can operate at over 300% efficiency, making them an excellent choice for energy-conscious homeowners.

In colder climates like Edmonton, heat pumps are often paired with backup heating sources, such as electric resistance heaters or a furnace, to ensure the home remains warm during extremely cold temperatures. While heat pumps can operate in freezing temperatures, their efficiency decreases as the outside temperature drops significantly, which is why backup heating is sometimes necessary.

Furnace vs. Heat Pump: Installation Costs

When considering the cost of installation, it’s important to factor in both the upfront and long-term costs.

Furnace Installation Costs

The installation cost of a furnace depends on factors such as the size of your home, the type of fuel used (gas, oil, electric), and the complexity of the installation. On average, a new furnace installation can cost anywhere from $3,000 to $7,000 or more, including labor and materials. While the initial installation costs may seem higher, a furnace is a reliable option that can heat your home efficiently in extremely cold conditions.

Heat Pump Installation Costs

The installation cost of a heat pump can also vary based on the size of your home, the model chosen, and the complexity of installation. A heat pump typically costs between $4,000 and $10,000 or more, which includes both heating and cooling capabilities. While the upfront costs can be higher than those of a furnace, heat pumps have lower operating costs because of their energy efficiency, making them a long-term cost-effective option.

Furnace vs. Heat Pump: Maintenance and Lifespan

Furnace Maintenance

Furnaces require regular maintenance to ensure they continue to operate efficiently and safely. This includes annual inspections, cleaning the blower and burner, replacing filters, and checking the ductwork for leaks. Regular maintenance can extend the lifespan of a furnace, which typically lasts between 15 to 20 years.

Heat Pump Maintenance

Heat pumps also require regular maintenance, including cleaning the filters, checking refrigerant levels, and ensuring that the outdoor unit is free from debris. Since heat pumps serve as both heating and cooling systems, they tend to experience more wear and tear than a furnace, leading to a shorter lifespan of around 10 to 15 years. However, with proper care, heat pumps can still provide reliable service for many years.

Which System Is Right for Your Home?

When choosing between a furnace and a heat pump, several factors should be considered:

• Climate: In colder climates like Edmonton, a furnace is typically the more reliable option because it can produce a large amount of heat even in freezing temperatures. Heat pumps are great for moderate climates and can work well in homes where temperatures rarely dip below freezing.
• Energy Efficiency: If energy efficiency is a priority and you live in an area with mild winters, a heat pump may be the better option. Heat pumps provide consistent, energy-efficient heating and cooling throughout the year.
• Installation and Maintenance Costs: While the initial cost of a furnace may be lower, heat pumps can provide significant long-term savings due to their high efficiency. Consider your budget and long-term goals when deciding which system to invest in.
• Backup Heat: If you choose a heat pump, you may need a backup heating system for very cold weather, which can add to the overall cost.
