Heat Pump vs Propane Furnace: How to Choose the Best Heating System for Your Home

Heat Pump vs Propane Furnace

Heat Pump vs Propane Furnace: If you are looking for a new heating system for your home, you might be wondering whether to choose a heat pump or a propane furnace. Both systems have pros and cons, and the best option for you depends on several factors, such as your climate, budget, energy efficiency preferences, and comfort level. 

In this blog post, we will compare heat pumps vs propane furnaces in terms of how they work, how much they cost, how efficient they are, how durable they are, how easy they are to maintain, and how they affect the environment.

How do They work?

A heat pump is a device that transfers heat from one place to another using a refrigerant cycle. It can work as both a heater and an air conditioner, depending on the direction of the heat transfer. In the heating mode, a heat pump extracts heat from the outside air, even when cold, and pumps it into your home. In the cooling mode, it reverses the process, removes heat from your house, and dumps it outside.

A propane furnace is a device that burns propane gas to create heat. It uses a burner, a heat exchanger, a blower, and a flue to heat the air and distribute it throughout your home via ductwork. A propane furnace requires a propane tank to store the fuel and must be refilled periodically.

Cost Comparison

The cost of a heat pump vs propane furnace depends on several factors, such as the system’s size, efficiency, quality, installation fees, fuel prices, and operating costs. Here are some general estimates:

  • Heat Pump Installation: Typically ranges from $3,500 to $4,500, depending on the heat pump type (air source, ground source, or water source), installation complexity, and existing ductwork.
  • Propane Furnace Installation: Averages between $2,500 and $4,000, influenced by furnace efficiency and quality, installation complexity, and existing ductwork. Additionally, consider the propane tank cost, ranging from $500 to $3,000 based on size and location.

  • Operating costs for a heat pump versus a propane furnace depend on electricity and propane prices, system efficiency, and usage. In 2023, the average residential electricity was 13.31 cents/kWh, and propane was $2.02/gallon. A heat pump costs about $1,500/year, and a propane furnace about $2,400/year. Costs vary by location, thermostat settings, and insulation.

Efficiency Comparison

Different metrics measure the efficiency of a heat pump vs a propane furnace. For a heat pump, the most common metric is the heating seasonal performance factor (HSPF), which is the ratio of the total heat output to the total electricity input over a heating season. The higher the HSPF, the more efficient the heat pump. The minimum HSPF for a heat pump is 7.7, and the most efficient models can reach up to 13.5.

For a propane furnace, the most common metric is the annual fuel utilization efficiency (AFUE), which is the percentage of the propane energy converted into heat. The higher the AFUE, the more efficient the furnace. The minimum AFUE for a propane furnace is 80%, and the most efficient models can reach up to 98%.

Durability Comparison

The durability of a heat pump vs propane furnace depends on the system’s quality, installation, maintenance, and usage. Generally, a heat pump can last between 10 and 15 years, while a propane furnace can last between 15 and 20 years. However, these lifespans can vary depending on the frequency of repairs, the climate, and the wear and tear.

Maintenance Comparison

Maintenance of a heat pump vs propane furnace is essential to ensure the system’s optimal performance, efficiency, and longevity. Both systems require regular inspections, cleaning, and tune-ups by a professional HVAC technician at least once a year. Additionally, both systems require some basic maintenance tasks by the homeowner, such as changing the air filters, clearing the debris, and checking the thermostat.

However, a propane furnace also requires extra maintenance tasks, such as refilling the propane tank, checking the gas lines, and testing the carbon monoxide detectors. If improperly maintained, a propane furnace also poses a higher risk of fire, explosion, and carbon monoxide poisoning.

Environment Comparison

The environmental impact of a heat pump versus a propane furnace depends on the electricity source and emissions. A heat pump transfers heat using electricity sourced from renewable or non-renewable sources. A heat pump’s carbon footprint is low with renewable sources like solar, wind, or hydro but higher with non-renewable sources like coal, oil, or natural gas.

A propane furnace utilizes propane gas, a fossil fuel that emits carbon dioxide, nitrogen oxides, and pollutants when burned. According to the U.S. Environmental Protection Agency, propane has lower carbon intensity than other fossil fuels. Yet, it still contributes to greenhouse gas emissions and climate change.

Heat Pump vs Propane Furnace: Which Is Best for You?

The best heating system for your home depends on your personal preferences, your budget, your climate, and your home’s characteristics. Here are some general guidelines to help you decide:

A heat pump might be a better option for you if:

  • You live in a mild to moderate climate, where the temperature rarely drops below freezing.
  • You want a system that provides heating and cooling in one unit.
  • You want a more energy-efficient and environmentally friendly system, especially if you have access to renewable electricity sources.
  • You should pay a higher upfront cost for a lower operating cost in the long run.

A propane furnace might be a better option for you if:

  • You live in a cold climate, where temperatures frequently drop below freezing.
  • You already have a separate cooling system, such as a central air conditioner or a window unit.
  • You want a more robust and reliable system, especially in extreme weather conditions.
  • You should pay a lower upfront cost for a higher operating cost in the long run.
