This convenience saves me both time and money in the long run.

My Buying Guides on 120 Gallon Propane Tank Cost
When I was looking to buy a 120 gallon propane tank, I quickly realized that understanding the cost involves several factors. I want to share my experience and insights to help you make an informed decision.
1. Initial Purchase Price
The first thing I checked was the upfront cost of the tank itself. For a 120 gallon propane tank, the price typically ranges between $800 and $1,500 depending on the brand, material (steel or aluminum), and whether it is new or used. I found that new tanks are safer and often come with warranties, which made me lean toward buying new despite the higher price.
2. Installation Costs
Buying the tank is only part of the expense. I had to factor in installation fees, which can vary widely. Installation costs often range from $300 to $700 depending on the complexity of the setup, local labor rates, and whether you need permits or inspections. For me, hiring a certified professional was important to ensure safety and compliance.
3. Delivery and Transportation Fees
Since 120 gallon propane tanks are quite heavy and bulky, I had to pay for delivery. This cost depends on the distance from the supplier to my home but usually adds $100 to $300 to the total price. Some suppliers include delivery in their quotes, so I always asked upfront.
4. Additional Equipment and Accessories**
I also considered the cost of accessories like regulators, hoses, mounting brackets, and safety valves. These extras can add a few hundred dollars to the total cost. It’s important to check what comes with the tank and what you need to buy separately.
5. Refilling Costs and Usage
While not part of the initial purchase, I wanted to understand ongoing costs. Refilling a 120 gallon tank costs around $1.50 to $3.00 per gallon depending on propane prices and location. I calculated how often I’d need refills based on my usage to budget accordingly.
6. Leasing vs. Buying Considerations
I also explored leasing options, where some companies provide the tank at little or no upfront cost but charge a monthly fee. This can be convenient but might be more expensive over time. Buying the tank outright gave me full ownership and flexibility.
7. Local Regulations and Permits
Before purchasing, I checked local laws regarding propane tanks. Some areas require permits or have restrictions on tank placement. These requirements can add time and cost to the process, so I recommend researching this early.
Final Thoughts
Overall, my total cost for purchasing and installing a 120 gallon propane tank was around $2,000 to $2,500. Prices will vary, but by considering all these factors, I felt confident in my investment. If you’re in the market for a tank, take your time to compare quotes and ask plenty of questions!
I hope my guide helps you navigate the costs and make the best choice for your needs.
