Above-Ground vs Underground Propane Tanks: Which Is Better

The Pros and Cons of Above-Ground vs. Underground Propane Tanks

Choosing the right propane tank installation for your home or business is an important decision that impacts both functionality and aesthetics. At Coombs Gas, we’re here to help you understand the key differences between above-ground and underground propane tanks so you can select the option that best fits your needs. Check out the pros and cons of each option below to help guide your decision.

Above-Ground Propane Tanks

Above-ground propane tanks are installed on a concrete or gravel pad, typically in an accessible location near your home or business.

Pros

Lower Installation Cost - Above-ground tanks are easier and less expensive to install since they don’t require excavation or special coating for burial.

  • Easier Maintenance and Inspection - These tanks are fully visible, making it simple to check for rust, damage, or leaks. Routine maintenance is straightforward and often quicker than underground tanks.

  • Flexibility for Relocation - If you move or decide to switch tank sizes, above-ground tanks can be relocated with minimal effort and cost compared to underground tanks.

  • Reliable in Flood-Prone Areas - In regions with a high water table, above-ground tanks are a better choice because underground tanks can float if not properly anchored during flooding.

Cons

  • Aesthetic Impact - Some homeowners find above-ground tanks less visually appealing. While they can be concealed with landscaping or fencing, they may still disrupt the look of your yard.

  • Temperature Sensitivity - Above-ground tanks are more exposed to extreme temperatures. In colder climates, the propane inside may be subject to pressure drops, potentially affecting performance.

Underground Propane Tanks

Underground propane tanks are buried below the surface, leaving only a small dome visible for access.

Pros

  • Improved Aesthetics - With the tank hidden underground, your yard remains uncluttered and visually appealing, allowing for landscaping or outdoor projects without obstruction.

  • Temperature Stability - Underground tanks are less affected by extreme temperature changes, ensuring consistent propane pressure and performance throughout the year.

  • Increased Property Value - Many buyers appreciate the aesthetic and practical benefits of underground tanks, potentially enhancing your home's resale value.

Cons

  • Higher Installation Costs - Installing an underground tank requires excavation, additional materials like anti-corrosion coatings, and anchoring systems, making it more expensive upfront.

  • Maintenance Challenges - While these tanks are durable, repairs or inspections are more complex since they require excavation to access the buried tank.

  • Flooding Risks - In areas with high water tables, underground tanks need to be properly anchored to prevent them from floating during floods. Improper installation can result in costly issues.

  • Potential Soil Impact - Over time, leaks from an underground tank could affect the surrounding soil, though modern tanks are designed to minimize this risk.

Factors to Consider When Choosing

Aesthetics

If maintaining a clean, open yard is a priority, an underground tank may be worth the investment. For those who don’t mind the appearance of a visible tank (or are willing to landscape around it), above-ground tanks are a great option.

Budget

Above-ground propane tanks are more affordable to install and maintain, making them ideal for homeowners seeking a cost-effective solution. If you’re willing to invest more upfront for long-term benefits, an underground tank may be the way to go.

Local Regulations

Some areas have specific zoning laws or environmental considerations that dictate where and how propane tanks can be installed. Check with Coombs Gas for guidance on local requirements.

Environmental Conditions

If your property is prone to flooding or has a high water table, above-ground tanks might be the safer choice.

Tank Size

Larger tanks, such as those used for whole-home heating, are often installed underground to minimize their visual impact. Smaller tanks are typically above-ground due to ease of access and portability.
