Number of Dependent Propane Appliances

Space Available 

Homeowners should check the area on their property where the new propane tank will be installed. A larger horizontal propane tank requires a wide yard. You may have to install a vertical propane tank if you own a small yard. Contact a reputable propane company to learn about your options.

Location of the Home

Your propane needs also rely on the region’s climate. Some areas may experience harsher winters. Homeowners should also consider how close the propane provider is to their home. Deliveries from far away mean you may have to wait a long time if the weather is bad. Choosing a large tank that can last longer is prudent in this situation.

Why Do You Need to Find the Right Propane Tank Size?

Here are several reasons it is important to have a suitable propane tank size at home:

Avoiding Frequent Propane Deliveries

A tank that’s too small for your home means the propane will be depleted quickly. As a result, you will require frequent propane deliveries. This can cause inconveniences and difficulties when there’s bad weather. Avoid this issue by getting the right propane tank size.

Minimizing Upfront Propane Fuel Costs

Some homeowners may be attracted to buying the biggest tank available to prevent the need for frequent deliveries. However, this isn’t always the practical route. Keep in mind that large propane tanks require large spaces. Large tanks also come with a heftier price tag. However, having a larger propane tank means you can take advantage of reducing propane costs because you can buy the fuel in bulk.

Considering Safety Regulations

Propane is quite safe, but local governments remain cautious about propane tank installation. Larger tanks have stricter regulations in place than smaller ones. You should consider the feasibility of the rules before installing a larger tank.

What Do Home Propane Tank Sizes Refer To?

Tank sizes can be described in one of two ways: volume and weight. Volume refers to the liquid in gallons within the tanks. On the other hand, weight is in pounds when the tank is full. Regardless, the tanks should only be filled up to 80% of their capacity. The 20% acts as a safety buffer for expansion.
