Propane Backup vs. Electric Heat Strips Explained

When winter storms hit and temperatures drop, having a reliable heating system becomes essential. Let’s compare two common heating backup options: propane systems and electric heat strips.

What Is Propane Backup Heat?

Gas is a reliable heating alternative that uses gas to provide warmth in extreme weather when heat pumps become ineffective, or the main heating system fails.

What Are Electric Heat Strips?

Electric heat strips are backup heating elements installed in many heat pump systems. They work like a giant toaster, using electricity to create heat when your main system can’t keep up with demand.

Why Propane Beats Electric Heat Strips

Performance in Extreme Cold:
- Electric Heat Strips: When temperatures drop below 35F-40°F, heat pumps struggle. The heat strips kick in, but heat slowly and often can’t keep up in severe cold without being very costly to run.
- Propane Backup: Gas heaters produce much hotter air (120-140°F) than heat strips (85-95°F). Therefore, your home will warm up faster, even when it’s freezing outside.
Power Outage Protection:
- Electric Heat Strips: When the power goes out, so do your electric heat strips. During winter storms—when you need heat most—you’re left in the cold.
- Propane Backup: Many of these systems can run even during power outages when paired with a generator. Your family stays warm regardless of what’s happening outside.
Energy Efficiency:
- Electric Heat Strips: They use a lot of electricity. When they run constantly during cold snaps, your electric bill will skyrocket.
- Propane Backup: These systems heat more efficiently, using less energy to create more warmth, resulting in lower utility bills during the coldest months.

Feature	Propane Backup	Electric Heat Strips
Air Temperature	120-140°F output	Only 85-95°F output
During Power Outages	Works with a generator to run the fan	Require a much larger generator
Cost Efficiency	More efficient heating	Cause huge electric bills

Is Propane Backup Right for You?

This type of heating makes the most sense if you:

Live in areas prone to winter power outages
Experience temperatures below 35F-40°F
Want consistent warmth regardless of weather conditions
Are concerned about winter energy costs
