A standard 20 lb propane tank lasts about 10 hours on high with a typical 40,000 BTU patio heater. Adjust heat settings for longer use.
How Long Does Propane Tank Last Of Patio Heater
Got an awesome patio setup and want to keep cozy even when the weather turns chilly? A propane patio heater is where it’s at! But before you fire it up, there’s one question nagging at you: how long does a propane tank actually last for one of these things?
The answer isn’t a one-size-fits-all situation. It depends on a few factors, like:
- Size of your propane tank: These babies usually come in 20 lb tanks, which are the standard for your typical BBQ grill too.
- BTU output of your heater: Think of this as the heater’s power level. The more BTUs, the more propane it guzzles.
- Your heat setting: Blasting it on high will drain that tank way faster than a gentle simmer.
So, How Long Will It Really Last?
Okay, let’s get down to brass tacks. Here’s a general idea of what you’re looking at:
- Standard 20 lb tank + Typical 40,000 BTU heater = Around 10 hours on high
That’s a solid evening or two of cozy warmth! Keep in mind that cranking the heat down a notch can stretch that time out even longer.
Propane Tank Time Chart
Need a quick reference guide? Here’s a handy chart showing how long a standard 20 lb propane tank is likely to last at different BTU outputs on a high heat setting:
| BTU Output | Approx. Run Time (High Setting) |
| 15,000 BTU | About 28 hours |
| 30,000 BTU | About 14 hours |
| 40,000 BTU | About 10 hours |
| 50,000 BTU | About 8 hours |
How to Make Your Propane Last Longer
Nobody wants their propane tank to run dry mid-party! Here are some savvy tricks to stretch that fuel:
- Weather woes: Windy days make your heater work harder, sucking down more propane to keep things toasty. Can you shield your patio a bit for better warmth?
- Reflective heat: Think of placing a heat-resistant surface behind your heater. This helps bounce some of that warmth back toward you rather than letting it dissipate.
- Smaller cozy zones: Trying to heat a massive patio space with a single heater is a losing battle. Focus on creating a smaller, more intimate area with your seating.
Propane Cost-Effectiveness
Patio heaters aren’t just about the initial investment. Consider the propane cost too. Here’s a rough breakdown:
| Tank Size | Tank Capacity (Approx) | Cost to Fill (Estimate) |
| 20 lb. | 4.7 gallons | $15 – $20 |
Just remember, these prices can vary depending on where you live and propane’s current market value.
Factors That Can Affect Propane Usage
It’s not just about the numbers on the label. A couple of sneaky things can mess with your propane burn time:
- Cold temperatures: When it’s freezing out, your heater chugs harder to reach the desired temperature.
- Older tanks: If your propane tank is ancient, it might not be holding a full capacity anymore.
Is a Larger Propane Tank the Answer?
If you find yourself refilling your tank constantly, a larger option might be tempting. This is definitely doable, but keep a few things in mind:
- Larger tanks are bulkier and harder to move.
- You’ll have a bigger upfront cost for the tank itself.
- Not all patio heaters are designed to accommodate giant tanks.
Table: Propane Tank Sizes (Standard)
| Tank Capacity | Common Uses | Notes |
| 20 lbs | Barbecue grills, patio heaters, small RVs | Most portable and readily available. |
| 30 lbs | Larger barbecues, some RVs | Less frequent refills than a 20 lb tank. |
| 40 lbs | Commercial grills, larger RVs | Not usually ideal for patio portability. |
Propane vs. Electric Patio Heaters
Hold on a second! Propane might be popular, but are there other options out there? Electric patio heaters are worth considering. Here’s the lowdown:
- Propane: The Pros
- Super portable. Take your warmth anywhere!
- Often provide more powerful heat output.
- No electrical cords to contend with.
- Propane: The Cons
- Gotta deal with propane refills.
- Can be more affected by wind.
- Safety concerns regarding propane storage and leaks.
- Electric: The Pros
- No fuel to worry about – just plug and play!
- Often less expensive to operate long-term.
- Generally considered safer than propane.
- Electric: The Cons
- Limited by cord range and outlet availability.
- Might have a lower max heat output.
Safety First!
Whether you rock propane or electric, safety is non-negotiable. Here’s your quick patio heater safety checklist:
- Ventilation is your friend: Propane heaters need good airflow to prevent carbon monoxide build-up. Never use them in enclosed spaces!
- Keep a safe distance: Check your heater’s manual for those specific ‘keep away’ clearances from flammable stuff.
- Maintenance matters: Clean your heater regularly and inspect hoses/connections for damage (propane models).
- Supervise closely: Never leave a running heater unattended, especially around kiddos or curious pets.
Tips for Choosing the Right Patio Heater
With all this info swirling around your head, how do you actually pick the best heater for you? Consider these key points:
- Patio Size: Small space vs. sprawling party patio? Make sure the heater’s BTU output matches your needs.
- Style: Dozens of designs – freestanding, tabletop, hanging… Pick one that vibes with your aesthetic.
- Features: Some models have things like tilt safety switches, auto shut-off, or even remote controls!
Table: Common Patio Heater Types
| Type | Description | Ideal For |
| Freestanding (Pole) | Tall, slim design disperses heat in a circle | Larger patios, open areas |
| Tabletop | Compact, sits on a table like a centerpiece | Smaller, intimate spaces |
| Wall/Ceiling Mounted | Permanently installed, saves floor space | Covered patios, defined seating areas |
Conclusion: How Long Does Propane Tank Last Of Patio Heater?
So, How Long Will Your Propane Last?
Let’s recap! The length of time your propane tank will power your patio heater depends on the tank’s size, the heater’s BTU output, and how high you’re cranking that heat. A smaller tank on a high-powered heater might only get you a few hours of cozy time, while a larger tank on a lower setting could last days.
Remember, proper maintenance, smart heater placement, and keeping an eye on the weather can help you get the most out of your propane investment.
