Underground propane tanks help retain your curb appeal. Once buried, only the lid is seen protruding from the ground. The lid keeps the regulator, gauges, and filling port from exposure to the elements. We offer different propane tank sizes to meet a wide range of residential and commercial needs. When filled, the volume of propane is approximately 80% of the total tank capacity to allow for expansion.
These large propane tanks are typically used for whole-home systems, home heating, generators, pool heat, commercial cooking, drying cleaning, and crop drying. The tank is about 6′ 3/16″ tall and 15′ 11″ long. It is appropriate for most buildings ranging from 4500 sq. ft. and up. Metered systems for small communities and shared commercial buildings commonly install 1000-gallon propane tanks as their central propane storage.
This underground propane tank requires you to dig a hole in the yard on your property. Excavating the yard will cause damage and leave a large patch of dirt. However, you can plant grass and sod, and you’ll eventually be able to plant and landscape this space. In fact, the yard can end up looking even better than before and help raise the value of your property!
Above-ground propane tanks can be an eyesore and can require more creative landscaping to hide. Underground propane tanks are also surrounded by earth so they’re not as affected by weather conditions and freezing temperatures as above-ground tanks.
