Is a Dual Fuel Heating System Right for You?

Dual fuel heating systems offer uninterrupted heating when you need it most. This two-in-one solution combines an electric heat pump and a propane or gas furnace, forming a reliable, energy-efficient system for year-round comfort, even when the temperature drops.

Many Ontarians are switching to a dual fuel system as it offers multiple benefits, including savings on electric bills, stable temperatures during cooler months, and indoor comfort. But before you replace your current HVAC, learn more about how this heat pump and furnace combo works to see if it’s right for you. 

What Is a Dual Fuel System? 

A dual fuel system is an energy-efficient solution that combines the benefits of both a heat pump and a furnace. By automatically switching between these two distinct heat sources, a dual fuel system maximizes the efficiency and functionality of your HVAC system.

Heat Pumps Versus Furnaces: How They Differ 

Both heat pumps and furnaces heat houses, but they do it in different ways and use different fuel sources. Furnaces burn propane or natural gas to generate heat. A heat exchanger warms air, which is distributed around the house through a duct system. Furnaces offer powerful heating capabilities during the winter months, but can not be used to cool houses in the summer.

Heat pumps use electricity and have both heating and cooling abilities. A heat pump transfers heat between inside and outside air, so these flexible systems can change their function based on the temperature outside. During winter, a heat pump extracts the limited heat from outdoor air and transfers it indoors to increase temperature. The system works in reverse during the summer, giving it some of the same functionality as an air conditioner.

How Does a Heat Pump and Furnace Work Together? 

The heat pump and furnace combo monitors outdoor temperatures and selects the most cost-effective heating source based on its readings. In this hybrid unit, the dual fuel heat pump acts as the primary heat source as its overall energy costs are lower than a furnace.

However, heat pumps become ineffective in extremely cold weather because there’s little to no heat to extract from the outside air. The unit switches to the secondary heat source, the furnace, which burns fuel to quickly produce heat and maintain a comfortable temperature inside. 

Benefits of a Heat Pump and Furnace Combo 

Combining a heat pump and furnace means doubling your HVAC’s efficiency. Each system has its strengths and weaknesses, but these heating sources maximize efficiency, help you save money, and address any comfort concerns. 

Higher Energy Efficiency

The energy efficiency of a hybrid unit comes from its ability to switch between the furnace and the heat pump. Depending on outdoor conditions, the system automatically selects the heat source that makes the most sense, ensuring a consistent flow of warm air in your home.

Cost Effective 

A dual fuel heating system relies on the heat pump’s functions most of the year, which is seen on utility bills as reduced energy costs. An electric heat pump uses less energy to deliver the same heating and cooling effects as furnaces and air conditioners, respectively. 

Lower Carbon Footprint 

A dual fuel HVAC is an eco-friendly choice since it operates using electricity for most of the year. Traditional furnaces use non-renewable energy sources like fossil fuels and natural gasses that release harmful emissions into the environment.

Guaranteed Flexibility 

With the right installation, a dual fuel furnace and heat pump combo is sufficient in most weather conditions. HVAC experts match a hybrid unit’s settings to region, weather, and utility cost data. In turn, you can control which cost-effective heating source is right for you.

Factors to Consider Before Choosing a Dual Fuel System 

Now that we’ve explored what a dual fuel heating system is, you can decide if it’s a good solution for your home. Before you decide, it’s important to consider the following factors:

Climate and Region 

While dual fuel heating systems are suitable for most climates, a high-efficiency furnace may be a better option in colder regions with long, harsh winters, like Northern Ontario. As for Southern Ontario, a heat pump and furnace combo is well suited for the region’s cold winters and warm summers. 

Comfort 

It’s important to consider air quality when choosing a heating system. A dual fuel heating system harnesses the power of both heating and cooling systems to maintain comfortable temperatures indoors. However, installing a humidifier can further improve your home environment by balancing moisture levels in the air for maximum comfort.

Costs 

Dual HVAC systems have higher initial costs, and installation can also be expensive. However, the long-term savings on electricity bills and lower environmental impact make them worthwhile investments.

If you already have an existing heat pump or furnace, costs may be lower, as you’ll only need to purchase one system to complete the hybrid set. Additionally, the Ontario government has an HVAC rebate program that can grant up to $5,000 to eligible homeowners!
