Understanding Blackstone 28” Griddle Propane Requirements

Knowing the propane needs of your Blackstone 28” griddle helps you choose the right tank for efficient cooking. Matching fuel consumption with tank size prevents interruptions and ensures consistent heat.

How Much Propane the Griddle Uses

The Blackstone 28” griddle consumes about 40,000 BTUs per hour. This high output demands a propane supply that maintains steady heat during extended cooking sessions. At this rate, your griddle uses approximately 1 pound of propane every hour since 1 gallon of propane contains roughly 91,500 BTUs.

Typical Cooking Time Per Propane Tank Size

Cooking duration varies by tank size based on its propane capacity and the griddle’s BTU usage.

Propane Tank Size Propane Capacity (lbs) Estimated Cooking Time (hours)
5 lb Cylinder 5 5
10 lb Cylinder 10 10
20 lb Cylinder 20 20
30 lb Cylinder 30 30

You can expect a 20 lb tank to power the griddle for about 20 hours at medium heat. Smaller tanks suit short grilling but require frequent replacement. Larger tanks extend cooking time but add weight and reduce portability.

Common Propane Tank Sizes for Blackstone 28” Griddle

Choosing the right propane tank size for your Blackstone 28” griddle impacts cooking time and mobility. Various tank sizes suit different usage patterns and transport needs.

5-Pound Propane Tanks

Use 5-pound tanks for short cooking sessions or when portability matters most. These tanks provide about 5 hours of cooking time on your griddle. Their compact size makes them easy to carry, ideal for camping or tailgating. You may need to refuel frequently during extended use.

10-Pound Propane Tanks

Opt for 10-pound tanks to balance cooking duration and portability. These tanks last roughly 10 hours on the griddle, supporting medium-length cooking without excessive weight. They’re suitable for backyard meals or small gatherings, offering a convenient option without the bulk of larger tanks.

20-Pound Propane Tanks

Select 20-pound tanks to maximize cooking time with minimal refilling. These tanks deliver approximately 20 hours of griddle use, fitting well for regular cooking or larger events. While heavier, they ensure consistent heat output for prolonged grilling sessions. They require a suitable storage location when not in use.

Benefits of Using Different Propane Tank Sizes

Choosing the right propane tank size for your Blackstone 28” griddle impacts portability, cooking duration, and cost efficiency. Understanding these benefits helps you select a tank that fits your grilling style and needs.

Portability and Convenience

Smaller tanks, such as 5-pound cylinders, enhance portability. You can easily transport them to picnics, tailgates, or camping trips. Their light weight prevents strain during carrying and makes storage simpler. Larger tanks, like 20-pound models, add weight and take up more space, which reduces convenience but offers longer cooking sessions without interruption.

Cooking Duration and Refill Frequency

A 5-pound tank provides about 5 hours of cooking time. If you grill frequently or cook for large groups, a 20-pound tank delivers roughly 20 hours of uninterrupted heat, minimizing refill stops. Medium-sized tanks, such as 10 pounds, balance cooking time and refill frequency with around 10 hours of use. Picking a tank based on how long you cook reduces the risk of running out of propane mid-meal.

Cost Considerations

Smaller propane tanks typically cost less upfront but require more frequent refills, potentially increasing long-term expenses. Larger tanks have higher initial costs but reduce refill frequency and may lower overall propane expenses. Factoring in refill costs helps you choose a tank size that fits your budget while maximizing efficiency.

Choosing the Right Propane Tank for Your Needs

Selecting the correct propane tank depends on your cooking habits, outdoor space, and safety requirements. These factors ensure you get the most from your Blackstone 28” griddle.

Assessing Your Cooking Habits

Evaluate how often and how long you cook. Frequent, extended cooking sessions benefit from larger tanks like 20 pounds, delivering about 20 hours of use. Casual or occasional use suits smaller tanks, such as 5 or 10 pounds, which offer portability and last 5 to 10 hours. Consider the typical number of guests and meal size to match tank capacity with your grilling demands.

Outdoor Space and Storage Factors

Measure the available storage and transport space. Compact areas favor smaller tanks that are easier to store and handle. If space isn’t limited, larger tanks provide longer cooking times without frequent refills. Ensure your storage location complies with local regulations regarding propane cylinders, including shelter from extreme temperatures and secure upright positioning.

Safety and Connection Compatibility

Verify the propane tank’s valve and connection match your griddle’s fittings to avoid leaks or performance issues. Standard tanks generally use POL or Type 1 valves compatible with the Blackstone 28” griddle. Always inspect hoses and regulators for wear and use approved connectors. Maintain proper ventilation during use and storage for safety.

Conclusion

Choosing the right propane tank for your Blackstone 28” griddle means balancing how often you cook with how long you want to grill without interruptions. Whether you prioritize portability or extended cooking time, there’s a tank size that fits your needs perfectly.

Pay attention to compatibility and safety to ensure smooth performance and peace of mind. With the right tank, you’ll enjoy consistent heat and make every cookout a success.
