A lot of buzz is going around heat pumps these days! Which is the better option—a heat Pump or a Furnace for Canadian Winters? Some experts say heat pumps are not efficient below a certain temperature, while others say they save on energy bills.

When comparing a gas furnace to a heat pump, consider factors such as how they work, cost, energy efficiency, performance, maintenance, lifespan, appearance, and safety considerations.

What is a Heat Pump?

A heat pump is a heating and cooling system that moves heat from one place to another rather than generating heat directly. These systems work by scavenging heat from the air outside, transferring it to a liquid refrigerant, and then pumping the refrigerant to a coil or heat exchanger inside the home’s ductwork. A fan then blows air across the coil, heating up the air before it’s dispersed through the rooms.

Pros of a Heat Pump:

• They are highly energy-efficient, as they transfer heat rather than generating it directly
• It can provide both heating and cooling functions, acting as an all-in-one HVAC system
• Typically, they have a longer lifespan than furnaces, with an average of 15-20 years
• There is no need to store or combust fuel, making them a cleaner heating option

Cons of a Heat Pump:

• Less effective in extremely cold climates (below around 5°C/40°F), when they may need supplementary heating
• Higher upfront installation costs compared to furnaces
• Require both indoor and outdoor units, taking up more space
• It can be noisier than furnaces due to the outdoor compressor unit

What is a Furnace?

A furnace is a forced-hot-air heating system connected to ductwork throughout the home. These systems use fuel oil, propane, natural gas, or electricity to heat a burner, and then a large fan blows air across a heat exchanger to disperse the heated air through the ductwork.

Pros of a Furnace:

• Highly effective at heating in cold climates, with no loss of efficiency at low temperatures
• Generally have lower upfront installation costs than heat pumps
• It is a simpler system with only an indoor unit, taking up less space
• Quieter operation than heat pumps (no outdoor compressor unit)

Cons of a Furnace:

• Requires the storage and combustion of fuel, which can be less environmentally friendly
• Can have higher ongoing operating costs, especially with natural gas or propane
• They have a shorter average lifespan of 15-20 years compared to heat pumps
• Can’t provide cooling functions, requiring a separate air conditioning system

Key Differences Between Heat Pumps and Furnaces

While heat pumps and furnaces share the common goal of heating a home, they have some significant differences that are important to understand:

Cost

One of the first questions homeowners typically ask when comparing heat pumps and furnaces is which one costs more. The answer can vary depending on your home’s existing setup. Homes with direct access to natural gas may find that a furnace is more affordable, as the installation costs for the gas line are already covered, while a home without gas access will likely pay more to install a furnace system.

Generally speaking, a heat pump system will have higher upfront installation costs than a furnace, but the ongoing operating costs are often lower due to greater energy efficiency.

Energy Efficiency

From a pure efficiency standpoint, highly efficient heat pump systems are technically more energy-efficient than even the most high-efficiency furnaces. Heat pumps can transfer significantly more energy than they use, making them extremely efficient.

The story gets more complex when considering the energy source. Heat pumps generally use less energy in warmer climates than gas furnaces. However, in colder climates, high-efficiency gas furnaces can be more efficient than ENERGY STAR Certified Heat Pumps, especially when factoring in the relatively lower cost of natural gas compared to electricity.

Performance

When it comes to heating performance, furnaces generally have the edge in colder climates. Traditional furnaces can provide effective heating even when outdoor temperatures drop below freezing. On the other hand, heat pumps can start to lose efficiency when temperatures dip below around five °C (40°F) and may require supplementary heating at very low temperatures.

However, heat pumps have the advantage of providing both heating and cooling functions, acting as an all-in-one HVAC system. Furnaces are strictly for heating, requiring a separate air conditioning system for cooling.

Maintenance

Both heat pumps and furnaces need regular maintenance to function efficiently and have a long lifespan. Homeowners can easily replace the air filters in both systems. Heat pumps also require annual cleaning and inspection of the outdoor unit, while furnaces, although not requiring an outdoor unit, are often paired with a central air conditioning system that does have an outdoor component.

Lifespan

On average, both heat pumps and furnaces have a similar lifespan of around 15-20 years, with proper maintenance. The longevity of these systems depends on factors like usage patterns, system size, installation quality, thermostat settings, and environmental conditions. Regular maintenance and timely repairs can extend the lifespan of both heat pumps and furnaces.

Appearance

Heat pumps are the less aesthetically pleasing option, as they require a large standalone unit to be installed outside the home. On the other hand, furniture is typically much more unobtrusive, as it is generally installed in out-of-the-way locations like basements, attics, or utility rooms.

Safety Considerations

Gas furnaces pose a higher risk of gas explosions and carbon monoxide poisoning compared to electric heat pumps. However, gas furnaces typically have built-in safety features like automatic shut-off valves and pressure regulators to prevent such incidents. Electric heat pumps have their own safety features, such as automatic shut-off switches and refrigerant leak detectors.

Regardless of the heating system, it’s important to have a qualified technician regularly maintain and inspect the equipment to ensure its continued safe and efficient operation.

Dual Fuel Systems: The Best of Both Worlds?

For homeowners looking to get the best of both worlds, dual fuel systems might be the answer. These systems blend a heat pump’s energy efficiency with a gas furnace’s raw heating power.

In a dual-fuel system, the heat pump handles most of the heating duties, using its efficient heat transfer capabilities to keep the home warm. However, when outdoor temperatures drop to the point where the heat pump starts to lose efficiency, the system automatically switches to the gas furnace to provide the necessary supplementary heating.

This combination allows homeowners to enjoy the energy savings and versatility of a heat pump for most of the year while still having the reliable heating power of a furnace for those extremely cold winter days. Dual fuel systems can be a great solution for Canadian homeowners looking for a heating system that can handle the diverse climate.

FAQs

Is a Heat Pump Better Than a Furnace?

There needs to be a more complex answer to this question, as heat pumps and furnaces have advantages. Heat pumps are generally more energy-efficient and versatile, providing both heating and cooling functions. However, furnaces are typically more effective at heating in colder climates. The “better” option depends on your home, climate, and heating needs.

How Do I Know if I Have a Furnace or Heat Pump?

The easiest way to tell if you have a furnace or a heat pump is to look at the system’s components. Furnace and boiler systems have all their components inside the home, while heat pumps have indoor and outdoor units.

Should I Switch from a Furnace to a Heat Pump?

For most homeowners, switching from a furnace to a heat pump is the better option. Heat pumps are generally more energy-efficient and can provide both heating and cooling, acting as an all-in-one HVAC system. However, heat pumps may be less effective in extremely cold climates, so it’s important to carefully consider your local weather conditions before making the switch.
