My Buying Guides on 120 Gallon Residential Propane Tank
When I decided to purchase a 120 gallon residential propane tank, I realized there were several important factors to consider to ensure I got the right tank for my home’s needs. Here’s what I learned through my experience, and what I think will help you make an informed decision.
Understanding the Size and Capacity
At first, I wondered if 120 gallons would be enough for my household. This size is generally ideal for small to medium residential use, powering appliances like water heaters, stoves, or fireplaces. It stores approximately 120 gallons of propane, but remember that propane tanks are usually filled to about 80% capacity for safety reasons, so usable propane is closer to 96 gallons.
Assessing Your Propane Needs
I took stock of all the propane appliances I have and estimated their consumption. If you have multiple appliances or higher usage, you might need a larger tank or more frequent refills. For me, the 120 gallon size struck a good balance between storage capacity and space requirements.
Material and Durability
Most residential propane tanks, including the 120 gallon models, are made of steel. I looked for a tank with a durable, corrosion-resistant coating to ensure longevity. Some tanks also come with powder-coated finishes which provide extra protection against weather and rust.
Safety Features
Safety was a big concern for me. I made sure the tank I chose met all relevant safety standards and included features such as pressure relief valves, proper venting, and secure fittings. It’s also important to have the tank installed by a certified professional to comply with local regulations.
Installation Considerations
Before buying, I checked the space where I planned to install the tank. The 120 gallon tank is relatively compact but still requires proper clearance from buildings, property lines, and ignition sources. I also made sure the installation site was level and accessible for refilling trucks.
Refilling Options and Costs
I researched local propane suppliers to find the best prices and reliable delivery services. Since the 120 gallon tank is smaller than some commercial sizes, refill frequency might be higher, so I factored that into the ongoing cost and convenience.
Budget and Pricing
When shopping, I compared prices not just for the tank itself but also for installation and permits. Prices can vary depending on the brand, features, and location. Sometimes spending a bit more upfront for a quality tank and professional installation can save money and headaches down the road.
Maintenance and Longevity
Once installed, I learned that regular inspections and maintenance are key to keeping the tank in good shape. Checking for leaks, rust, or damage helps prevent costly repairs or safety issues. Most tanks come with warranties that I made sure to review.
Final Thoughts
Choosing a 120 gallon residential propane tank was a straightforward process once I knew what to look for. By understanding my propane needs, focusing on safety and durability, and planning for installation and refills, I found a tank that perfectly fits my home. I hope my guide helps you make the right choice too!
