A propane tank exchange is what you would order when you have a used grill tank, that you want to exchange for a fresh grill tank containing a net weight of 15lbs of propane. The price for an exchange tank is much lower since we take your used tanks with us. You can exchange any brand of grill tank if it is a standard grill-size tank. You choose the location… just give us instructions on where to access your used grill tank and we handle the rest.
A spare tank is a ready to use grill tank containing a net weight of 15lbs of propane that you purchase without exchanging a used grill tank. Since you are buying both the propane and the steel cylinder, the price is higher than an exchange purchase. If you do not have a propane grill tank already on hand for your device, you should order a spare tank.
