In the picturesque San Juan Islands, where the climate can shift from crisp to chilly, a reliable and efficient heating source is essential for comfortable living. Propane heat emerges as a standout feature for homes in this region, offering a blend of affordability, efficiency, and environmental benefits. As a cleaner alternative to oil and generally more cost-effective than electricity, propane is increasingly the fuel of choice for island homeowners. Its efficiency surpasses that of natural gas, making it an attractive option for those seeking to minimize their environmental impact while keeping their homes warm. This guide explores the advantages of propane heat and provides critical questions to ask when purchasing a home with a propane system in the San Juan Islands, with insights into how Inter Island Propane supports the community.

Why Propane Heat is so important in the San Juans

Propane heat is highly valued in the San Juan Islands for several reasons:

  • Power Outages: Propane is important during power outages because it provides a reliable and long-lasting backup power source for generators. Unlike gasoline or diesel, propane doesn't degrade over time, ensuring it's ready when needed, and it's also readily available and can be transported and delivered even during widespread outages. “We like the ability to be able to cook and use our propane fireplace when the power is out. We are considering adding a propane generator”- Denny S from Friday Harbor

  • Cost-Effectiveness: Propane is typically cheaper than electricity, helping homeowners save on energy bills, especially during the colder months.

  • Efficiency: Newer propane appliances are extremely efficient, delivering consistent heat with less fuel consumption.

  • Environmental Benefits: As a cleaner-burning fuel compared to oil, propane aligns with the eco-conscious values of many island residents.

  • Versatility: Beyond heating, propane can power appliances such as stoves, water heaters, clothes dryers, hot tubs, generators and even outdoor barbecues, enhancing home functionality.

For homebuyers, a propane-heated home in the San Juan Islands likely represents a smart investment, combining comfort with long-term savings. However, transitioning to a home with propane heat involves considerations that may differ from gas, oil, or electric systems, making it essential to gather detailed information from the seller, your home inspector or your local propane company.

Five Essential Questions to Ask When Buying a Propane-Heated Home

To make an informed decision when purchasing a home with propane heat, consider asking the seller the following questions. These inquiries will help you understand the propane system’s setup, costs, and maintenance history, ensuring a smooth transition to your new home.

1. What Is Propane Being Used For?

Propane’s versatility makes it a valuable fuel for various household functions. In the San Juan Islands, it is most commonly used for:

  • Heating: Space heaters, furnaces, or boilers to keep homes warm.

  • Appliances: Stoves, ovens, water heaters, and clothes dryers.

  • Outdoor Use: Barbeques or patio heaters for enjoying island evenings.

If the home has recently converted to propane, not all appliances may be propane-compatible. For example, an electric stove might need upgrading to a propane model to maximize the fuel’s benefits. Understanding the current uses of propane will help you assess whether additional investments in appliances are necessary, impacting your budget and offer.

2. Who Owns the Propane Tank At The Home I'm Buying?

Propane tanks can either be owned outright by the homeowner or rented from a propane provider like Inter Island Propane. Each option has distinct advantages and considerations:

Ownership Type

Pros

Cons

Owned Outright

No monthly rental fees; greater control over fuel decisions; long-term cost savings.

Upfront purchase cost (reflected in home price); homeowner responsible for maintenance and repairs.

Rented

No maintenance or replacement costs; easy transfer of rental agreement; lower initial costs.

Monthly rental fees; less control over tank decisions.


Inter Island Propane, your trusted local provider, often rents tanks to homeowners but also offers the option to purchase them outright. If you choose to rent, we can seamlessly transfer the agreement upon home purchase. If buying the tank, ensure you receive documentation proving ownership to avoid future disputes.

3. How Big Is the Residential Propane Tank?

The size of the propane tank directly affects how often you’ll need to schedule deliveries, which is particularly relevant in the San Juan Islands, where outer island access may be less frequent. Residential tanks typically range from 120 to over 1,000 gallons:

  • Smaller Tanks (120–250 gallons): Suitable for homes with minimal propane use, such as for a single appliance.

  • Medium Tanks (500 gallons): Common for homes using propane for heating and multiple appliances.

  • Large Tanks (1,000+ gallons): Ideal for larger homes or those on outer islands, reducing delivery frequency.

Ask the seller about the tank’s size to estimate delivery needs. Inter Island Propane can provide guidance on selecting the right tank size based on your household’s consumption patterns, ensuring you’re prepared for island living.

4. Are Propane Tanks Under or Above Ground?

Propane tanks can be installed either above ground or underground, each with its own benefits:

Tank Placement

Pros

Cons

Above Ground

Easier and cheaper to install; simpler to access for maintenance.

Less aesthetically pleasing; takes up yard space.

Underground

More visually appealing; frees up yard space.

Higher installation costs; more complex maintenance.

Most rental tanks from Inter Island Propane are above ground due to cost and ease of installation. However, underground tanks may appeal to those prioritizing aesthetics. Discuss with Inter Island Propane to determine the best option for your property and whether installation services are needed.

5. Are Propane Tank Maintenance Records Available?

Like any home appliance, propane tanks require regular maintenance to ensure safety and efficiency. Key maintenance tasks include inspections for leaks, corrosion, or valve issues. When buying a home, request maintenance records from the seller to verify the tank’s condition. If records are unavailable, it’s prudent to have the tank inspected by a professional, such as Inter Island Propane’s experienced technicians, to identify potential issues before they become costly problems.
