My Buying Guide on 120 Gallon Horizontal Propane Tank
When I decided to invest in a 120-gallon horizontal propane tank, I quickly realized that there were several key factors to consider. Whether you’re looking to power your home, a business, or just need it for recreational use, here’s my comprehensive guide to help you make an informed decision.
Understanding Propane Tanks
Before I dive into specifics, let me clarify what a 120-gallon horizontal propane tank is. This type of tank is primarily used for residential heating, cooking, and hot water. It’s designed to be installed above ground and is perfect for spaces where vertical tanks won’t fit.
Assessing Your Needs
First, I had to assess my specific needs. I asked myself several questions:
- What will I use the propane for? Is it primarily for heating, cooking, or a generator?
- How often will I need to refill it? This depends on usage and the size of your household.
- What is my budget? Understanding how much I was willing to spend helped narrow down my options.
Choosing the Right Size
While I was focused on the 120-gallon option, I found that it’s crucial to ensure it’s the right size for my needs. This tank can hold enough propane for various applications, but if my usage was particularly high, I might have needed a larger tank. I suggest calculating your average monthly propane usage to determine if this size is suitable.
Material and Construction
I wanted a tank that would last, so I looked at the materials and construction quality. Most 120-gallon horizontal tanks are made from steel, which is durable and corrosion-resistant. I also considered looking for tanks that have undergone rigorous testing for safety standards.
Local Regulations and Codes
Before purchasing, I made sure to check local regulations regarding the installation and placement of propane tanks. Some areas have specific codes that must be followed, and I didn’t want to run into any issues later. This included distance requirements from buildings, property lines, and more.
Safety Features
Safety was a top priority for me. I looked for tanks equipped with safety features such as:
- Pressure relief valves: These prevent excessive pressure buildup.
- Overfill protection devices: They ensure the tank doesn’t get filled beyond its capacity.
- Corrosion-resistant coating: This extends the lifespan of the tank and enhances safety.
Installation Considerations
I learned that the installation process for a 120-gallon horizontal propane tank could be complex. I opted for professional installation to ensure it met all safety standards and regulations. If you’re considering DIY installation, make sure you’re well-versed in local codes and safety practices.
Maintenance Requirements
Maintaining my propane tank was something I wanted to keep in mind. Regular inspections for leaks, corrosion, and overall integrity are essential. I also found that having a contract with a propane supplier for regular maintenance and refills could save me time and hassle.
Finding a Reliable Supplier
After researching, I discovered the importance of choosing a reliable propane supplier. I looked for companies with positive customer reviews, good customer service, and competitive pricing. I also considered their delivery options and whether they offered emergency services.
In the end, my journey to purchasing a 120-gallon horizontal propane tank was thorough and rewarding. By assessing my needs, understanding safety features, and choosing the right supplier, I felt confident in my decision. I hope this guide helps you navigate your own buying process with ease!
