If you’re considering the use of propane as a heating fuel source for your home or business, you will need to install a tank to store the fuel reserves. Your choice essentially boils down to two options: an above ground or underground propane tank.
By evaluating several factors, you can determine which type is best for you and your property. Please note that it’s unsafe and often illegal to install a propane tank designed for above ground use under the ground. In any case, you should check to make sure your tank complies with all applicable EPA regulations and local zoning ordinances prior to installation.
If you’re like most property owners, appearance is extremely important. Many view a propane tank as an unsightly eyesore that can reduce a property’s aesthetic and curb appeal. If you’re unable to install an above ground tank in a discreet location that is not easily seen, you might want to choose an underground model. Some owners who have an above ground tank will choose to paint it.
Cost is always a consideration when choosing between an above ground or underground propane tank. An underground tank requires the installation of additional protective equipment to prevent corrosion and possible groundwater contamination. When combined with the digging and backfilling involved with the site excavation, the total projected cost of an underground tank can be up to three times the cost of an above ground unit.
An above ground tank poses certain security risks that don’t exist with underground tanks. For instance, a highly visible above ground tank can be susceptible to vandalism, making it less desirable for property owners in high-crime areas. If your tank is located near a roadway or parking area, it can also be vulnerable to vehicle collisions.

Underground tanks are better suited to handling extreme temperatures, particularly colder climates. Unlike above ground tanks, underground tanks are warmed by the earth, enabling them to continue to function at a high level even when the temperature dips well below zero.
There’s the possibility that an underground tank will float. This typically happens when the water level in the hole where the tank is buried rises above the level of the fuel inside the propane tank. Installing an underground tank on a concrete slab can minimize the floating risk. However, if you live in an area that is prone to flooding, an above ground tank may provide a better solution.
Above ground propane tanks are generally easier to maintain than underground units. Underground tanks contain an anti-corrosion component that must be inspected and tested on a regular basis, resulting in an additional cost to the owner. An improperly functioning anti-corrosion component will also need to be replaced.
Yes, underground propane tanks have been used for years and are safe. There are several advantages and disadvantages to weigh including cost, safety, home value, and more.
To ensure your propane tank is installed correctly and applies with all regulations, you should contact a qualified propane service provider to install your tank for you.
Below-ground propane tank prices vary greatly due to differences in service providers and locations. The average estimated cost of an underground tank is typically between $1,500 and $5,000.
Underground propane tank lifespans can vary depending on location, quality of installation, and levels of maintenance provided. However, the lifespan for an underground propane tank typically averages between 20 to 30 years.

I want to install an above ground tank to feed a power generator
Thank you Miguel. We would be happy to help. Call us or contact us and send us your information and we will follow up with you.
Thanks for talking about how an underground unit is more capable of handling extreme temperatures. My husband and I are planning on getting a propane tank for our new home and are unsure whether to use an above ground one or an underground one. Since we are prone to get extremely cold winters in our area, my husband and I will definitely pick the latter choice for our propane tank.
My brother and family just moved into their new house and there's no energy source yet. It was stated here that underground tanks are a better choice than above ground. Moreover, having the tank underground poses only a few threat to security.
I'm grateful for your advice about securing our propane tank. In my opinion, keeping valves turned off when not in use will help. But my concern is, how about if there is a smelly gas even if it's already closed? And there no noticeable damage to it? What do we need to do?
There is an old underground propane tank on my property that I will soon place a mobile home on. Should I be concerned about an explosion if it is disturbed or after 40+ years underground is it safe to just leave it alone?
I agree that cost will always be a consideration when choosing a propane tank. It's good to know that the cost of an underground tank can be up to three times the cost of an above ground unit, like you said. I'll have to really think about if that is the best decision for me.
You need to call a licensed plumber immediately and have them come find the leak and fix it right away!!!
I am a member of the Architectural Review Board in my community. Several resident's have requested to install power generators. I'm trying to find literature on the proper installation for above ground propane tanks abt 200gal and underground tanks. I need to convince our BOD we can do this safely. I can't seem to find documents on what's required on the Sarasota website.
