We invite you to review the following factors to consider when choosing the right propane tank size for your home:
Ideally, higher propane usage requires propane tanks with larger capacities. Determining your propane usage can help you prevent the inconvenience and risks associated with propane shortage in your home.
It also helps you maintain cost-effectiveness by avoiding payment for a larger tank size that exceeds your requirements.
Analyze the steps below to guide you on how to estimate your propane usage:
Determine the number of propane-powered appliances
Inspect your home appliances and utilities such as furnaces, fireplace, cooking appliances, hot water heaters, and more to determine whether they’re connected to propane sources. Reviewing the manufacturer labels on your appliances can also guide you on whether they use propane.
Remember also to assess the outdoor appliances such as grills. If you have previous home maintenance records, reviewing them can also help you determine the number of propane-powered devices.
Compiling a list of all appliances can improve your organization.
Identify the factors affecting usage
Identifying the factors affecting propane usage in your home can help you determine the overall consumption. These factors include your home and family size and external factors such as environmental changes.
Consider reviewing your home construction and architectural plans to get an accurate description of its size. Extreme weather conditions such as winter can increase your use of propane-powered utilities such as space heaters or home hot water heaters.
Calculate the annual consumption
Each appliance typically has a British Thermal Unit (BTU) indicating fuel consumption levels. Note the BTUs on all your propane-powered devices.
Considering the peak usage periods, family, and home size, you can estimate your annual propane consumption levels.
2021 statistics show that propane-powered devices such as a furnace, hot water heaters, fireplaces, patio heaters, stoves, and clothes dryers use 80, 20, 16, and three gallons of propane per month.
Compare your propane usage to the available propane tanks
If your household propane usage is minimal, for example, only for an outdoor grill, consider a small-size propane tank such as a 20 or 33-LB propane tank.
However, larger size propane tanks such as the 120, 250, 320, and 500-gallon propane tanks are suitable if your annual consumption estimate is high.
The space you have can determine the propane tank size you can get for your home. It can influence your choice in the following ways:
Propane tank size
Larger tanks can take up a lot of space, so a space availability limit may restrict you to smaller-sized propane tanks.
This smaller size tank are typically portable, making it easier to store them. Consider underground propane tanks if you have large propane power needs but limited space.
Propane is highly flammable, and any leakages can cause fire or explosion risks.
As a risk mitigation strategy, authorities typically set a specific distance from which you can store propane tanks in buildings. This minimizes the possibility of fire spreading or building structural destruction during propane accidents. As our most genuine advice we encourage you to educate yourself on what propane smells like, propane tank pressure, and how low you can safely let your propane levels get.
The regulations may vary depending on location, but most regulatory authorities typically define a 10-meter distance or even greater for larger-capacity propane tanks.
Small size tank may fit if your space availability isn’t insufficient to maintain regulatory compliance with larger tanks.
Propane tank installation and maintenance options
Large-capacity propane tanks such as the 1000-gallon propane tank are typically installed as underground tanks.
The installation process may require heavy machinery for excavation and installation. Limited space availability can make accessing the specific installation location difficult using heavy operating tools.
Likewise, maintenance may require excavating large propane tanks from underground placements for inspection and repair, and limited space availability may obstruct maintenance efforts.
Your home’s geographic location and its environs can determine the specific propane tank for you in the following ways:
The weather conditions in your home’s geographic location can significantly determine the appropriate propane tank size for you.
The cold weather increases your use of propane to meet your heating demands during the cold season. The appliances requiring higher propane demands include hot water heaters, propane furnaces, and space heaters.
Your appliances, such as outdoor grills and propane patios, may also require more propane.
Homeowners using large propane tanks that are relatively immobile or underground propane tanks use propane delivery trucks from their suppliers to facilitate refills.
If your home is also in a region with poor roads and rough terrain, getting refills for large-capacity propane tanks may take time. This will push you to utilize the more portable common propane tank sizes.
You can physically carry the smaller propane tanks to a nearby gas station or propane supplier for refills.
People living in regions that experience frequent power outages typically have higher propane usage for appliances like backup generators.
The power outage duration can also influence the propane tank size you decide to get. For instance, short power outages may require small propane tanks to provide generator fuel for the entire outage duration.
In contrast, extended power outages may require larger propane tanks. The above principle also applies to the frequency of outages. Additionally, generator size also matters because a larger generator consumes more propane and may require a larger propane tank.
Learning the legal regulations governing the different sizes of propane tanks can guide you when selecting the right size. Some of the legal regulations to consider can include:
Local regulatory authorities often provide propane tank permit requirements for you to obtain before installation. This allows them to maintain compliance with regulatory standards to ensure safety.
The permit requirements often include installation, zoning and land use, setback safety inspection, tank anchoring, and emergency access permits.
The permit requirements for different tank sizes vary, with smaller-size propane tank being less than those for larger ones. Comparing household energy needs to the hassle of achieving specific tank size permits can help you determine a suitable tank size.
The population density of residential areas may influence the legal requirements for propane tanks. Areas with high residential density typically have stricter regulations.
The primary reason for such restrictions is the population’s safety. Primarily, a higher population density increases the risks associated with propane use and storage. A higher population density can also indicate limited installation space.
Hence, limiting large-capacity propane tanks that may compromise the general community layout is essential.
Transportation and Delivery
The primary purpose of these regulations is to ensure safe transportation, delivery, and handling of propane.
Propane transportation trucks may sometimes have additional features, such as a widened truck body that may limit access to certain roads.
Installing a large capacity underground tank in such an area may affect maintenance and refill operations because access limits make it more convenient to take a smaller size propane tank.
Roadway regulations sometimes also include truck weight limits to maintain the road’s integrity forcing large trucks to use alternate routes.
Environmental concerns in certain locations may influence the regulatory restrictions on propane tanks.
For instance, areas around large water bodies and schools with an enormous potential for impact following propane accidents may have stricter propane usage regulations.
If you live in such an area, consider selecting a smaller-capacity propane tank with a lesser risk of environmental effects following any propane accidents.
The amount you’re willing to spend for purchase, installation, and maintenance can influence your choice of propane tank size as follows:
Propane tank cost
The cost of purchasing a propane tank typically varies depending on the tank’s size. A larger propane tank typically requires more materials to produce, making it more expensive to purchase than smaller propane tanks.
The amount of money you’re willing to spend on purchasing one will influence the propane tank size you get.
Delivery charges vary depending on the propane tank size, as larger propane tanks may require different transportation than smaller tanks during installation.
Delivery of the propane refills also varies, depending on the tank’s size. Although the refill cost for large, especially underground tanks, may be high, they’re less frequent. Hence, they’re more economical than smaller propane tanks with a higher refill frequency.
Installing a large propane tank requires excavation and groundwork, which can significantly increase the installation expenses.
This installation may require you to hire excavation machinery, tools, and labor, making it costly. Unlike large-capacity propane tanks, you can easily store the small-size propane tank above ground due to its smaller dimensions and capacity making it more affordable.
Supplier availability varies in different regions depending on demand and may influence the propane tank size you decide to purchase in the following ways:
High supplier availability in your area may create a competitive business environment. Stiff competition among suppliers may expose you to competitive prices and availability. Therefore, purchasing larger propane tanks is easier and more affordable.
High supplier availability can also reduce the cost of additional services, such as delivery costs, as they strive to maintain a competitive advantage in the market, making installation, maintenance, and refills cheaper.
Purchasing a large-capacity propane tank can reduce the refill frequency. This is a suitable solution if you’re located in areas with limited supplier availability. The large fuel capacity can ensure sufficient propane supply even between deliveries.
In contrast, delivery times are shorter in areas with high supplier availability offering refill convenience that may push you to get a smaller size propane tank.
Emergencies may sometimes affect supplier availability. These situations may include severe weather conditions that may restrict supplier movement.
A larger propane tank can get you through such situations due to the higher runtime. Hence, they provide an emergency energy supply until supply availability returns to normal.
If you’re still weighting between different propane providers here’s how to chose the right propane delivery company.
Maintenance and Safety Considerations
Reviewing the safety and maintenance considerations regarding propane tank use can help determine a suitable propane tank size for your home. Some safety and maintenance factors include the following:
Leak Detection and Monitoring
Although propane tanks are relatively safe, they may leak if not installed properly, creating a fire or explosion hazard. Regular monitoring is essential to detect such leakages.
Leakage detection is simple for small propane tanks but complicated for larger propane tanks. These monitoring techniques include:
- using odorants such as ethyl mercaptan
- monitoring pressure gauges on the tank, which may be costly.
Opting for smaller propane tanks with simpler leakage monitoring techniques can save costs.
Considering the expertise you require to manage propane tank safety and maintenance operations can influence the propane tank size you choose.
Smaller propane tanks require less expertise to conduct safety and maintenance checks, unlike the larger ones, which may require trained professionals.
Accessing such specialists to conduct regular inspections and maintenance may be difficult because of their availability and cost. Getting a large-capacity propane tank is feasible if safety and maintenance specialists are available in your area.
Ideally, larger capacity propane tanks offer higher risks, making it essential to conduct frequent inspections. Because of the complex nature of the reviews, large propane tanks may require specialized personnel.
Additionally, increasing the frequency of inspections can expose you to a greater risk of fines and penalties if regulatory compliance isn’t met. Assessing the tank’s inspection requirements can guide you in deciding if purchasing a specific tank size is worthwhile.
Emergency Shut-Off Features
Larger propane tanks require more surrounding room for emergency access to fix leakages or other faults that may cause harm.
The emergency shut-off systems for large propane tanks are more complicated and costly than for smaller tanks. Apart from installing the emergency shut-off mechanisms, regular inspection and maintenance is necessary to ensure they function properly.
The emergency shut-off valves work by isolating the propane supply to the connected appliances, limiting the damage. Consider installing smaller ones if you cannot install and maintain these emergency measures for larger tanks.
Anticipating changes in your household propane usage can help you ensure sufficient propane supply. Factors that may influence your household’s future needs can include:
Anticipating home expansions such as additional rooms, kitchen expansion, workshop, or home office construction can help you accurately determine what propane tank size to get.
Increasing the house’s square footage can increase propane usage due to increased energy needs, such as increased home heating requirements.
Installing large propane tanks can reduce costs and maintain household operations efficiently if you intend to make home expansions.
Family Size Growth
Anticipating growth in family size can help you predict your future propane needs when determining a suitable propane tank size to install.
Welcoming new members to the household can contribute to a growth in the family size, increasing propane usage. If you foresee no family size growth, installing a smaller capacity propane tank is sufficient but may be inadequate if the size increases.
Change of Energy Sources
The need for energy efficiency, independence, consistent supply, and environmental considerations can influence people to change their energy sources. Apart from being an eco-friendly, clean-burning fuel, propane can provide a cheaper alternative and power many household applications. A large propane tank can maintain a sufficient energy supply if you change your energy sources.
Aesthetics and Landscaping
Your overall aesthetic and landscaping needs can influence your propane tank size choice in the following ways:
Outdoor features such as pathways and outdoor patios or decks will improve the outlook of your homestead. However, installing large-capacity propane tanks may interfere with your outdoor features or reduce their aesthetic value.
If you’re interested in adding such outdoor features, a smaller propane tank may be a better option as it may be less obstructive, allowing better utility of the outside space.
You may live where your neighbors value unobstructed views and attractive neighborhood environments. Installing a large capacity propane tank that may reduce the aesthetic value of the neighborhood may affect your neighbor relations.
In such an environment, smaller-capacity propane tanks that may camouflage within the environment offers a suitable alternative.
Property Resell Value
Installing a propane tank that blends well with your landscape can positively impact your property’s resell value.
Large propane tanks may affect the property’s aesthetic, reducing its resell value. In such a case, if you cannot install an underground tank, consider purchasing a smaller propane tank.
How much Propane is ideal for your home? There’s no standard amount we can consider as enough primarily because it all depends on the imminent needs. Nonetheless, buying a small propane tank makes sense if you just need gas for simple household applications.
Still, as we have seen, buying large tanks has its upsides. You’ll have limited refill frequencies, which also helps you stay put when propane gas prices fluctuate.
So ideally, you should balance a huge tank’s high acquisition cost and a smaller one’s frequent refill costs.
