56% of Canadian households heat with furnaces and 24% use electric baseboard heating. Both can be expensive.

Hybrid heating systems (also called dual-fuel systems) have emerged as an excellent solution that combines the benefits of two different technologies – typically a traditional furnace and a heat pump.

Continue reading to learn about the pros and cons of hybrid heating systems, including how they work, initial costs, operating costs, and where they make the most sense.

What is a Hybrid Heating System?

A hybrid heating system combines two different heating systems to maximize your energy efficiency and comfort.

Typically, it pairs a traditional gas or oil furnace with an electric heat pump. The furnace is responsible for heating your home during extremely cold weather, while the heat pump[gk1] takes over during milder conditions.

A smart thermostat switches between these two heat sources based on the outdoor temperature.

What Are The Components Of A Hybrid System?

A typical hybrid system includes the following components:

• A traditional furnace: This is a gas or oil furnace which provides powerful heating during any weather.
• A heat pump: The heat pump extracts heat from the outdoor air and transfers it into your home. It operates efficiently in temperatures down to between -5°C and -25°C (depending on the model).
• A duct system: The warm (or cold) air is distributed throughout your house via a network of ducts, which start at the hybrid equipment and extend to each of the heated spaces.
• A smart thermostat: The thermostat monitors indoor and outdoor temperatures. It controls the transition between the furnace and the heat pump to optimize energy efficiency and comfort by assessing the current furnace fuel and electricity prices, indoor and outdoor temperatures, and equipment performance characteristics.

How Does Hybrid Heating Work?

Hybrid heating systems rely on a smart thermostat to determine the most efficient way to heat your home.

When the outdoor temperature is mild, the system uses the heat pump, which extracts heat from the outdoor air and pumps it into your home. This method is highly efficient, as it doesn’t rely on burning fossil fuels.

When the temperature drops significantly, the smart thermostat starts up the traditional furnace. Furnaces generate heat by burning natural gas or oil and distributing it through the home’s ductwork. This is more suitable for extreme cold.

The smart thermostat continuously monitors outdoor temperatures and makes the switch between the two heating methods automatically. This seamless transition ensures consistent indoor comfort while optimizing energy efficiency.

Hybrid Heating System Pros

Energy Efficiency

A significant advantage of a hybrid heating system is its energy efficiency.

The heat pump operates by transferring heat from the outside air to your home’s interior. This uses much less energy than traditional heating methods, which burn fossil fuels.

A heat pump can transfer 300% to 400% more energy than it uses, whereas the most efficient furnaces can turn 97% of its energy into heat.

This lowers your energy bills, which is particularly appealing where Canadian winters can be harsh, making your heating costs substantial.

Cost Savings

With a hybrid heating system, homeowners can experience considerable cost savings, especially in regions with fluctuating winter temperatures.

During milder periods, the heat pump takes over, using electricity instead of consuming more expensive fossil fuels.

The system’s ability to adapt to changing weather conditions means you can enjoy the benefits of both technologies without breaking the bank.

Environmental Benefits

Hybrid heating systems are environmentally friendly, as they significantly reduce greenhouse gas emissions. Home heating is the second-largest contributor to greenhouse gas (GHG) emissions in Canada, and a hybrid system could produce 30% less GHG than a furnace alone.

The electricity they use to transfer heat produces less greenhouse gases than the furnace would produce for the same amount of heating—much less in areas where green electricity is available from wind or hydropower.

This promotes Canada’s commitment to sustainability and its efforts to reduce carbon emissions.

Comfort and Consistency

Hybrid systems provide consistent and comfortable heating throughout the year. While heat pumps offer even heating and cooling, the furnace component ensures your home remains warm during the coldest days of winter.

This dual functionality results in a comfortable indoor environment throughout the year.

Hybrid Heating System Cons

Initial Cost

One of the main drawbacks of a hybrid heating system is the initial cost.

Installing a hybrid system can be more expensive than a conventional furnace or heat pump. Homeowners need to consider the cost of both components, along with installation expenses.

However, it’s essential to remember that this initial investment can be recouped through energy savings in the long run.

Installation Complexities

Installing a hybrid heating system is more complex than setting up a traditional heating system.

It requires both a furnace and a heat pump, which means more components and potential complications. Proper installation is crucial to ensure the system operates properly and efficiently.

Therefore, it’s essential to hire a qualified HVAC technician with experience in hybrid systems.

Maintenance and Repairs

Hybrid systems may require more maintenance and repairs due to their dual nature.

Both the furnace and the heat pump need regular servicing, which can add to the long-term cost of ownership. Homeowners should budget for ongoing maintenance to keep the system running smoothly.

How Much Does A Hybrid Heating System Cost?

The cost of a hybrid heating system can vary significantly depending on factors such as the size of your home, local market conditions, and the specific components you choose.

On average, a hybrid system can range from $8,000 to $12,000 or more for the initial installation. This cost includes the furnace, heat pump, thermostat, and installation.

While the upfront cost may be higher than that of a conventional heating system, it’s estimated that the savings can pay for the system in three to five years.

Also, government incentives and rebates are often available to help offset the initial cost of hybrid systems, encouraging homeowners to adopt more energy-efficient solutions.

Furnaces vs. Heat Pumps vs. Hybrid

To better understand the advantages of hybrid heating systems, it’s essential to compare them to conventional furnaces and heat pumps.

Furnaces

Furnaces are the traditional heating systems in many Canadian homes. They typically burn natural gas or oil to create heat that provides reliable heating during any weather.

Heat Pumps

Heat pumps are highly energy-efficient heating and cooling systems that work by transferring heat between the indoors and outdoors. They do not create heat.

They are ideal for moderate climates but lose efficiency as the temperatures drop below freezing, and they may not provide enough heating in many parts of Canada in the winter.

Hybrid Heating Systems

Hybrid systems combine the strengths of both: during mild weather, the heat pump provides cost-effective heating until the temperature dips too low, at which point the furnace takes over.

This dual approach offers superior energy efficiency and cost savings, making hybrid systems an attractive option for many Canadian homeowners.

When Does a Hybrid System Make Sense?

Hybrid heating systems can offer a practical and cost-effective solution to homeowners in several areas:

Do you live in a place where the temperature changes over a wide range?

If you live in an area of Canada where the temperature varies from hot to very cold, a hybrid system optimizes energy usage yet keeps your home comfortable over the entire range.

Do local laws and incentives encourage energy efficiency?

Many provinces and territories in Canada have implemented incentives and regulations to promote energy efficiency. Hybrid systems often qualify for rebates and other financial incentives, making them more attractive to eco-conscious homeowners.

Does dry, hot heat in the winter impact your personal comfort?

Traditional furnaces tend to create a dry indoor environment during the winter, which can lead to discomfort and health issues. The heat pump helps maintain proper humidity levels, improving overall comfort.

How Can A Hybrid Heat System Save You Energy and Money?

A hybrid heating system is designed to maximize energy efficiency and cost savings. Here’s how it accomplishes this:

1. Efficient Use of Energy.

During mild weather, when using a furnace may be overkill, the heat pump operates, transferring heat from the outside to the inside of your home.

This process consumes less energy than burning fossil fuels or using electric resistance heating, giving you lower energy bills.

2. Adaptive Heating.

The smart thermostat uses the heat pump, the most energy-efficient heating source, whenever possible. It monitors outdoor temperatures and automatically switches to the furnace only when necessary to maintain comfortable indoor temperatures.

3. Reduced Carbon Footprint.

Using the heat pump minimizes the furnace’s consumption of fossil fuels, which produces more greenhouse gas emissions than the electricity driving the heat pump. This eco-friendly approach aligns with Canada’s commitment to environmental sustainability and can help homeowners reduce their carbon footprint.

4. Long-term Savings.

While the initial cost of a hybrid system can be higher, the potential for long-term savings on energy bills makes it a cost-effective choice. In colder regions, these savings can be substantial.
