When it comes to heating your outdoor space, the choice between electric and gas-powered porch heaters often boils down to cost, efficiency, and convenience. Each type has unique advantages and drawbacks, but which one is cheaper to run? Let’s dive into the numbers and practical considerations.

Quick answer: Gas porch heaters typically cost $1.50-$3.00 per hour to operate, while electric models average $0.20-$0.50 per hour. If electricity prices are stable in your area, electric heaters are cheaper for extended use. However, gas heaters excel in rapid heating for larger spaces.

Key Differences in Cost Per Hour

The operating cost of a heater largely depends on energy prices and consumption rates. Here’s a breakdown:

| Heater Type | Average Cost per Hour | Energy Source | Heat Output (BTU/W) | |---------------------|-----------------------|-------------------------|------------------------| | Electric Heater | $0.20-$0.50 | Electricity, 1500 W | 5,000 BTU | | Gas Heater | $1.50-$3.00 | Propane, 20 lbs tank | 40,000 BTU |

Electric heaters consume 1,500 W on average, costing about $0.12 per kWh in the U.S. Gas heaters, with propane priced at $3-$5 per gallon, cost significantly more to run but provide higher heat output. For short-term use, gas heaters may be worth the expense, especially in colder climates.

Efficiency: Which Heats Better?

Efficiency isn’t just about cost, it’s also about how effectively the heater warms your space. Electric models are best for small patios or enclosed areas. They provide steady heat without emissions but take longer to warm up. Gas heaters, on the other hand, deliver intense heat quickly, making them ideal for larger, open spaces.

Electric heaters convert nearly 100% of electricity into heat, but their lower BTU output limits effectiveness outdoors when temperatures drop below 50°F. Gas heaters, with outputs up to 40,000 BTU, can maintain warmth even in freezing conditions.

If your space is enclosed or you only use the heater sporadically, electric might be the smarter pick. For consistent outdoor use, gas heaters often justify their higher running costs.

Safety and Environmental Impact

Safety and environmental factors are often overlooked but critical. Electric heaters are safer for indoor or semi-enclosed spaces since they don’t produce emissions or require ventilation. Gas heaters need careful placement and regular maintenance to prevent hazards like carbon monoxide poisoning or fire risks.

Environmentally, electric heaters have lower carbon footprints if powered by renewable energy sources. Gas heaters rely on fossil fuels, which produce CO2 and contribute to air pollution.

Which Heater is Right for You?

Choosing the right heater depends on your specific needs. Here are some scenarios to help you decide:

  • Choose electric heaters if you’re heating a small, enclosed patio or if your area has low electricity rates. These are also ideal for households prioritizing safety and environmental sustainability.
  • Choose gas heaters for large, open outdoor spaces, especially in colder regions where high BTU heat output is necessary. They’re a better choice for hosting larger gatherings in winter.

FAQ

How much does a propane tank cost for a gas heater?

A standard 20 lbs propane tank costs $50-$60 and provides about 10 hours of heat on high settings. Refills are priced around $15-$20.

Do electric heaters work in freezing temperatures?

Electric heaters provide consistent heat but are less effective outdoors in freezing conditions. Their 5,000 BTU output is best for mild cold.

Which heater lasts longer?

Electric heaters typically last 10-15 years with minimal maintenance, while gas heaters average 7-10 years due to wear from combustion.

Can gas heaters be used indoors?

Gas heaters should only be used indoors if they're vented models or rated for indoor use. Otherwise, they pose carbon monoxide risks.

What’s the cheapest electric heater for outdoor use?

The Heat Storm HS-1500-PHX ($129) is a budget-friendly option with 1,500 W output and Wi-Fi controls.
