When installing a propane storage tank, the contractor must
consider proper tank sizing, safety, efficiency, ground char-
acteristics and aesthetics. For a residential customer, the
size may range from 100-1,000 gallons, depending on house-
hold use. Typically, a 500 gallon tank is ample for an aver-
age four-bedroom home. However, it is best to consult your
local propane supplier to ensure the proper sizing for pro-
pane storage requirements. Determining the correct tank
size for each household is a function of demand, economy,
efficiency and convenience. It is a process that requires co-
operation between the propane supplier and customer.
