Do winter's chilly days leave you longing for cozy comfort? Many homeowners wonder if using space heaters with furnace systems is a safe way to stay comfortable in freezing conditions. The thought of maximizing your main heating capabilities with space heating is understandable if you have a cold house. However, we recommend you consider the potential long-term implications before pulling your heater out of storage.

Can Furnaces and Space Heaters Work Together?

Your heating system is a complete home heating solution that distributes heat evenly through air ducts and vents. In contrast, portable heaters deliver additional warmth by targeting specific rooms. While this combination can make sense for temporary situations, relying too heavily on your space heater all winter may prevent you from noticing underlying issues that indicate the need for furnace repair or a new, economical furnace installation.

How Much Electricity Do Portable Heaters Use?

Space heater electricity use and wattage vary widely. If you've wisely kept up with routine furnace maintenance, relying on a space heater all winter will likely raise your bills instead of reducing them. Proactively addressing energy waste by replacing old insulation and air sealing materials typically delivers better results than combining a patchwork of solutions.

Precautions to Take When Using a Portable Space Heater With Your Furnace

Safety should always be a priority in your household. Portable heaters can create safety dangers if you put them too close to furniture or window treatments, so always maintain proper distances. Look for models with automatic shutoff mechanisms to reduce risks. Be mindful of circuit capacity and electrical limitations, since straining circuits can cause electrical issues. And remember to check your furnace ventilation to ensure you don't expose your family to increased toxic gas hazards when running your heat for months.

Potential Benefits of Space Heaters

Portable heaters provide personalized comfort by quickly warming rooms that feel colder than others. However, modern smart thermostats and programmable settings or zoning often achieve the same effect even more safely and efficiently. With smart thermostat optimization, you can fine-tune comfort settings, reduce power consumption and even improve indoor air quality at lower temps without relying on additional appliances.

Avoid these mistakes when using space heaters alongside your furnace:

  • Relying solely on space heaters to replace your heating system
  • Using old units that lack modern safety technology
  • Heater positioning that blocks airflow from heating registers
  • Using a space heater that is too small to adequately warm the target area

Alternatives to Space Heaters for Supplemental Heat

You don't have to use several units or keep lugging a heater around different rooms in your home. These solutions often outperform space heaters in safety and affordability:

  • Zone control systems for targeted comfort
  • Installing an updated, energy-efficient heating system for better performance ratings
  • Improving thermal barriers to reduce thermal leakage

Balancing Efficiency and Safety

Pairing a supplemental heater with your furnace can provide temporary comfort, but it's no substitute for investing in professional HVAC upkeep and long-term solutions like improved insulation. For lasting comfort, efficiency and safety, focus on keeping your furnace in optimal working order and exploring modern upgrades that deliver whole-house comfort with fewer risks.
