The best propane tanks and types for your home

There are two types of aboveground propane tanks: horizontal tanks and vertical cylinders.

Horizontal propane tanks (sometimes known as “torpedo tanks”) are big, high-capacity containers that are frequently used in homes where propane is the primary source of heat. Their enhanced storage capacity may reduce the requirement for winter propane delivery, which can be beneficial in locations where the weather is inclement.

Horizontal tanks and vertical cylinders

Vertical propane cylinders are smaller and can be hidden against a structure or along a property line.
