Above vs. Underground Propane Tank: Which One Is Best For Your Home?

If you’re considering purchasing a propane tank, it’s important to know how your propane equipment works and what the advantages and disadvantages are for each tank. A few weeks go, we explained how propane containers come in many shapes and sizes. Choosing the right size tank for your home is important because it can not only save you money on energy bills, but location also becomes a major factor in your decision-making as you move into the larger scale tanks.

We should note that not all propane tanks have an underground option. For example: smaller tanks that are commonly used for BBQ grills and propane heaters are meant to be portable and easy to carry, therefore are not available for an underground installation. Even 100lb tanks, which are bigger, but still relatively portable are only designed for above ground use.

But once you get to the larger tanks like the 500 to 1000 gallon tanks that are meant for whole home systems, you have the option for above or below ground installation. However, the first thing you should know is that, whether you choose above or below, both tanks will function the same. The biggest difference is obviously the aesthetics.


Some people might consider an above ground tank a major eyesore, or simply not like the fact that it will take a portion of their yard which could be devoted to a pool or swing set. However, it doesn’t actually take up more space then it’s underground-ground counterpart, and there are ways to discreetly hide your propane tank with landscaping, if it’s aesthetically unpleasant to look at for you.

Other things to consider with above ground tanks is that they will most likely be more exposed and vulnerable to extreme climates, making them less durable during severe conditions. However, if you’re in an area prone to flooding, an above-ground tank is often the better option, because if the water rises above the level of your underground propane tank, you risk it floating away from your home.

The biggest pro associated with above ground installation is the price, since there is no need for excavation, it keeps the cost down. Making it the more affordable option.

  • Quick Installation

  • Lower Costs

  • No Excavation Needed

  • Easy To Swap

Underground Tank

No doubt if you prefer a more manicured yard, an underground tank is the obvious choice. However, an underground tank will be costlier upfront due to the extra expenses for excavation, anti-corrosion coating, and labor costs. But on the bright-side, your lawn can go back to looking the way it was before with a little yard work.

Generally, underground tanks are also safer because they’re not exposed to the elements and in the event of a propane leak, it would be less harmful, since a gas leak would be more contained by the soil. And since propane is a green fuel it would not affect the local water or soil.

Homeowners will also be happy to know that an underground tank may increase the value of your home which is something to keep in mind if you’re thinking about the resale potential.

  • Landscape Friendly

  • Safer in Case of Propane Leak

  • Increases Home Value

At the end of the day, there is no right or wrong when choosing between an above ground or below ground tank. It just comes down to what will work best for you and your lifestyle.
