Why You Should Consider a Secondary Heat Source

1. Power Outages

Severe weather events such as ice storms and heavy snowfall can lead to widespread power outages, leaving homes without heat for hours or even days. In areas prone to outages, a secondary heat source can ensure that you and your family stay warm until power is restored.

2. Extreme Cold Temperatures

Canada experiences some of the coldest temperatures in the world, particularly in provinces like Alberta, Saskatchewan, and Manitoba. When temperatures drop to -30°C or lower, even the most efficient heating systems can struggle to maintain warmth. A backup heat source provides an extra layer of protection against extreme cold snaps.

3. Primary Heating System Failure

Like any mechanical system, furnaces and heat pumps can break down unexpectedly. If your primary heating system fails in the middle of winter, repairs may take time, leaving you without a reliable heat source. A secondary heat source ensures you have an alternative way to keep your home warm while waiting for repairs.

4. Fuel Supply Interruptions

Homes relying on oil, propane, or natural gas for heating can face supply shortages, especially in remote areas. If fuel deliveries are delayed due to bad weather or supply chain issues, a secondary heat source that uses a different type of fuel can keep your home warm.

5. Zoning and Energy Efficiency

Some homeowners opt for a secondary heat source to improve energy efficiency. For example, using a wood stove or pellet stove in frequently used areas can reduce reliance on central heating, lowering overall heating costs.

Common Secondary Heat Sources in Canada

1. Wood Stoves

Wood stoves are a popular choice for backup heat in rural and suburban homes. They provide consistent heat and do not rely on electricity, making them an excellent option for emergency situations. However, they require a steady supply of firewood and proper ventilation to operate safely.

2. Pellet Stoves

Pellet stoves burn compressed wood pellets and offer a more controlled, efficient heating alternative to traditional wood stoves. Some models require electricity to operate, but battery backup options are available to ensure continued functionality during power outages.

3. Propane or Gas Fireplaces

A propane or natural gas fireplace provides a convenient and efficient backup heating solution. Unlike wood stoves, they require minimal maintenance and offer instant heat at the flip of a switch. However, they do rely on a continuous fuel supply, which may be affected by supply shortages.

4. Electric Space Heaters

For homes with a generator, electric space heaters can provide localized warmth during power outages. They are affordable and easy to use but may not be practical for heating larger areas.

5. Radiant Floor Heating

Hydronic radiant floor heating, which uses heated water pipes under the floor, can serve as an excellent secondary heat source when paired with a backup generator. It provides even, consistent warmth but requires significant upfront investment.

6. Solar Heating Systems

Solar thermal heating systems use the sun’s energy to provide supplemental heat, reducing reliance on traditional heating methods. While not a primary emergency heat source, they can help offset heating costs and provide additional warmth during sunny winter days.

Cost Considerations

1. Upfront Installation Costs

The initial cost of a secondary heat source varies depending on the type of system chosen:

• Wood stove: $2,000–$5,000 (including installation)
• Pellet stove: $3,000–$6,000
• Gas fireplace: $3,500–$8,000
• Electric space heater: $50–$200
• Radiant floor heating: $10,000–$25,000
• Solar heating system: $5,000–$15,000

2. Fuel and Maintenance Costs

• Wood and pellet stoves require ongoing purchases of firewood or pellets, averaging $500–$1,500 per winter.
• Gas fireplaces rely on propane or natural gas, with costs varying based on local fuel prices.
• Electric space heaters increase electricity bills, making them less cost-effective for long-term heating.
• Radiant floor heating has minimal ongoing costs but requires professional maintenance.
• Solar heating systems have low operational costs but may need periodic servicing.

3. Emergency Preparedness Costs

If your secondary heat source requires electricity (e.g., pellet stoves, radiant floor heating), you may need to invest in a backup generator, which can cost between $2,000 and $10,000.

Choosing the Right Secondary Heat Source

When selecting a backup heating system, consider the following factors:

• Climate and frequency of power outages – Homes in remote areas with frequent outages should prioritize non-electric options like wood stoves.
• Home size and insulation – Larger homes may require a more robust backup system to heat multiple rooms.
• Availability of fuel – If wood or propane is scarce in your region, alternative heat sources may be more practical.
• Budget and long-term costs – Weigh upfront costs against ongoing fuel and maintenance expenses.
• Ease of use and maintenance – Some systems require regular upkeep, while others provide hassle-free operation.

Conclusion

A secondary heat source in Canada is not just a luxury—it’s a necessity for many homeowners facing harsh winters, power outages, and extreme temperatures. Whether you choose a wood stove, pellet stove, gas fireplace, or another backup option, investing in a reliable secondary heating system ensures your home stays warm and comfortable when you need it most. Before making a decision, consider the costs, maintenance requirements, and availability of fuel sources to find the best solution for your household.

FAQs

1. What is the best secondary heat source for power outages?

A wood stove or gas fireplace is ideal since they operate without electricity.

2. Are secondary heat sources required by building codes in Canada?

Most building codes do not require a backup heating system, but they are recommended in areas prone to extreme cold and outages.

3. Can I install a secondary heat source myself?

While some electric space heaters are plug-and-play, installing wood stoves, gas fireplaces, or radiant heating typically requires professional installation.

4. How much does it cost to run a secondary heat source?

Costs vary by fuel type—wood and pellet stoves can cost $500–$1,500 per winter, while gas fireplaces depend on local fuel prices.

5. What is the most energy-efficient backup heating system?

Pellet stoves and radiant floor heating systems are among the most energy-efficient options.
