How Much Does Propane Cost for Water Heater?

The cost of propane for a water heater can vary significantly depending on several factors, including the price of propane in your local area, the efficiency of your water heater, and the amount of hot water you consume. In this comprehensive guide, we’ll dive deep into the details to help you understand the true cost of using propane for your water heater.

Propane Prices: Understanding the Fluctuations

The average cost of propane in the United States is around $2.60 per gallon, according to recent data. However, this price can fluctuate based on supply and demand, as well as other market forces. Factors such as seasonal changes, global events, and regional supply and distribution can all impact the price of propane.

To get a more accurate estimate of the cost of propane in your area, it’s best to check with your local propane supplier or use online resources that provide up-to-date pricing information. Some websites, such as the U.S. Energy Information Administration (EIA), offer interactive maps and tools that allow you to view propane prices by state or region.

Calculating the Cost of Propane for Your Water Heater

To calculate the cost of using propane for your water heater, you’ll need to consider the following factors:

  1. Propane Consumption: The amount of propane your water heater consumes per day or per month. This can vary depending on the size and efficiency of your water heater, as well as your household’s hot water usage.

  2. Example: If your water heater consumes 0.35 gallons of propane per day and the cost of propane is $2.60 per gallon, the daily cost of propane for your water heater would be $0.91 (0.35 gallons x $2.60 per gallon).

  3. Thermal Efficiency: Propane water heaters typically have a thermal efficiency of around 90%, which means that only 90% of the energy consumed by the propane is used to heat water. The remaining 10% is lost through the venting system or other inefficiencies.

  4. Example: If your water heater has a thermal efficiency of 90%, the actual cost of using propane for your water heater would be $1.01 per day (daily cost of $0.91 / 0.90 thermal efficiency).

  5. Cost per BTU: When comparing the cost of propane to electricity, it’s important to consider the cost per British Thermal Unit (BTU) of each energy source. According to one source, the cost per BTU of propane is $0.000031, while the cost per BTU of electricity is $0.000038. However, these costs can vary depending on the price of each energy source in your area.

  6. Cost per Million BTUs: To determine which energy source is more cost-effective for your water heater, you can calculate the cost per million BTUs of each energy source. According to one source, the cost per million BTUs of propane is $38.48, while the cost per million BTUs of electricity is $35.17. However, these costs can vary depending on the price of each energy source in your area.

Factors Affecting Propane Water Heater Costs

In addition to the cost of propane, there are other factors that can impact the overall cost of using a propane water heater:

  1. Water Heater Efficiency: The efficiency of your water heater can significantly affect its energy consumption and, consequently, the cost of operation. More efficient water heaters, such as tankless or high-efficiency models, can help reduce the amount of propane required to heat water.

  2. Hot Water Usage: The amount of hot water your household consumes can also impact the cost of using a propane water heater. Households with higher hot water usage will generally have higher propane consumption and, therefore, higher operating costs.

  3. Installation and Maintenance: Installing a propane water heater requires specialized skills and knowledge, including proper venting and gas line installation. Hiring a licensed professional for the installation can add to the upfront cost. Additionally, regular maintenance, such as flushing the tank and inspecting the system, can help ensure the water heater operates efficiently and extend its lifespan.

DIY Installation Considerations

While it’s possible to install a propane water heater as a DIY project, it’s generally not recommended due to the specialized skills and knowledge required. Improper installation can lead to safety hazards, such as gas leaks or improper venting, which can be dangerous and potentially illegal in many areas.

If you do decide to attempt a DIY installation, it’s crucial to thoroughly research and understand the local building codes, safety regulations, and best practices for propane water heater installation. Failure to follow the proper procedures can result in costly repairs, fines, or even legal issues.

In most cases, it’s advisable to hire a licensed and experienced plumber or HVAC contractor to handle the installation of your propane water heater. While this may come with a higher upfront cost, it can help ensure the safety and long-term reliability of your water heating system.

Conclusion

The cost of propane for a water heater can vary significantly based on a variety of factors, including the price of propane in your local area, the efficiency of your water heater, and your household’s hot water usage. By understanding these factors and calculating the true cost of using propane for your water heater, you can make an informed decision on the most cost-effective energy source for your home.

Remember, while DIY installation may seem like a cost-saving option, it’s generally not recommended due to the specialized skills and knowledge required. Hiring a licensed professional can help ensure the safe and proper installation of your propane water heater, which can ultimately save you money in the long run.
