My Buying Guides on 120 Gallon Horizontal Propane Tank
When I decided to purchase a 120 gallon horizontal propane tank, I realized there were several important factors to consider to make the best choice. Here’s what I learned from my experience that might help you too.
Understanding the Capacity and Size
A 120 gallon tank holds roughly 480 pounds of propane, which is a good medium size for home heating, grilling, or running appliances. I made sure to measure the available space where I planned to install the tank because these horizontal tanks are quite long and need level ground.
Horizontal vs. Vertical Tanks
I chose a horizontal propane tank because it fits better in my yard and is easier to install near the house. Vertical tanks take up less footprint but can be less stable without proper mounting. Consider your installation space and local regulations before deciding on the orientation.
Material and Build Quality
Most propane tanks are made from steel and coated to prevent rust. I looked for a tank with a durable powder coating finish and thick steel walls. This ensures longevity and safety, especially in harsh weather conditions.
Safety Features to Look For
Safety is paramount when dealing with propane. My tank had a pressure relief valve, a shut-off valve, and was DOT certified. These features help prevent accidents and comply with federal and local safety standards.
Installation Requirements
I checked with my local authorities about permits and setback requirements. Installing a propane tank usually requires it to be a certain distance from buildings and property lines. Professional installation is highly recommended to ensure everything is done safely and up to code.
Maintenance Tips
To keep my tank in good shape, I regularly inspected it for rust or damage, checked valves for leaks, and made sure the area around it was clear of debris. Proper maintenance extends the tank’s lifespan and keeps it safe.
Price and Warranty Considerations
Prices vary depending on brand, features, and where you buy. I compared several options and chose a tank that offered a solid warranty—usually 10 to 20 years—which gave me peace of mind.
Where to Buy
I found reputable suppliers both online and locally. Buying from a certified dealer ensures the tank meets all safety standards and often includes delivery and installation services.
Final Thoughts
Buying a 120 gallon horizontal propane tank is an investment in convenience and energy efficiency. By focusing on capacity, safety, quality, and installation requirements, I was able to find a tank that fits my needs perfectly. I hope my guide helps you make an informed decision too!
